What is Active PFC?

Active Power Factor Correction improves the power factor value of the PSU by altering the input current wave shape. PSUs with Active PFC can achieve a power factor of 0.99, while PSUs with Passive PFC can only achieve 0.70, and PSUs with no PFC achieve less than 0.60. A higher power factor reduces transmission losses and improves efficiency for power companies, making Active PFC an important feature for the environment.

How can a PFC power supply save energy?

By reducing the volt-amperes your electric utility has to deliver in order to provide a gene power level demanded by the power supply. Much less power is lost in generating useless “harmonics” that unnecessarily load down the AC electrical delivery system.

Are PSUs with multiple +12V outputs more reliable than PSUs with a single +12V output?

Yes, multiple +12V outputs are used to ensure safety protection; each output keeps the current within a safe range. PSUs with a single +12V output generally tend to be older designs and present greater risk because, in the event of a short in any component, there is no over current protection.

Are multiple 12-volt rails better than a single 12-volt rail?

With all the hype about multiple 12-volt rails (ads claim that two rails is better than one, five is better than four, etc.), you’d think it was a better design. Unfortunately, it’s not! Here are the facts: A large, single 12-volt rail (without a 240VA limit) can transfer 100% of the 12-volt output from the PSU to the computer, while a multi-rail 12-volt design has distribution losses of up to 30% of the power supply’s rating. Those losses occur because power literally gets “trapped” on under-utilized rails. For example, if the 12-volt rail that powers the CPU is rated for 17 amps and the CPU only uses 7A, the remaining 10A is unusable, since it is isolated from the rest of the system. Since the maximum current from any one 12-volt rail of a multiple-rail PSU is limited to 20 amps (240VA / 12 volts = 20 amps), PCs with high-performance components that draw over 20 amps from the same rail are subject to over-current shutdowns. With power requirements for multiple processors and graphics cards continuing to grow, the multiple-rail design, with its 240VA limit per rail, is basically obsolete. PC Power and Cooling is once again leading the industry. All of our power supplies now feature a large, single 12-volt rail. The design is favored by major processor and graphics companies, complies with EPS12V specs (the 240VA limit is not a requirement) and is approved by all major safety agencies such as UL and TUV.3

How do I pick a good PSU?

It is not easy for a general user to judge if a PSU is good or not. Here are some principles. • Choose a well-known brand. • Has the PSU passed safety certifications? • Is the wattage number the value for peak output or continuous output? Continuous is better. • Compare the weight with other similar products to see if it is too light. • (Not suitable for passive PFC power supply) • Compare the internal components, if they have size difference. • Does the PSU have the 80 PLUS certification.

NA250A-PRO

How many GPU cards can this hold?

This NA-250A-PRO is only equipped with 400W Power Supply without any extra PCIE power connectorS. You cannot install any GPU cards on this product.

NA255A

Can the NA255A support up to 4 GPU cards?

The NA255A hardware can support up to 4 pcs GPU cards but the BIOS on some manufacturer’s motherboards were not designed This means that hardware will not be issue but the motherboard firmware is more likely to be the cause of a problem if it arises. From our records, only some ASUS motherboards will not work up to 4 GPU cards. Check with your motherboard’s manufacturer for further details regarding compatibility.

How loud and how fast are the cooling fans on the NA255A?

The max speed is at 34dB but default is running at speed of 65% and 22dB. The fan speed can be adjust by manual. How to adjust shows on web http://www.netstor.com.tw/product_info.aspx?SerID=6&Title=TurboBox&ArID=21&PID=PID_170324287237937

What if my MSI™ Z270 gaming motherboard doesn't recognize the NA255A?

The solution is as follows:

  1. Visit the MSI BIOS Download Page to download and update your MSI Z270 Gaming MoBo to the latest BIOS version 7A58v12 released on April 11, 2017.
  1. First, make sure to not have any card installed in slot 2, slot 3, and slot 4 on the MSI motherboard before proceeding.
  1. Install NA255A host card on MSI’s motherboard’s PCIe slot 1 for signal of electrically x16
  1. Connect the monitor to MSI motherboard’s onboard HDMI interface for screen output (see attached image file) so the monitor will utilize Intel Core i3-7100’s integrated HD Graphics 630 processor. In MSI’s MoBo BIOS settings, set i3-7100 integrated HD Graphics 630 as the top priority screen output processor.
  1. Power on your PC, and then the NA255A will be powered on along automatically. When the  Pc boots into Windows 10, the GTX 1080 gpu cards in NA255A will be recognized by WIN10’s Device Manager correctly.

I am interested in possibly using factory overclocked cards that are a little larger for maximum cooling. What is the max card height the NA255A can accomodate?

The NA255A can accommodate the max card height is 5.7”/145mm.

We have just received the NA250A-GPU and I have a question about the cards installation layout in my Mac Pro as well as the NA250A-GPU. The following are the details of my system and PCIe cards. Please advise what would be the best configuration of cards installation in both devices in order to achieve the best performance.

Please help to verify if the NA255A-XGPU is able to support 4 x GTX 980 or 4 x GTX1080 simultaneously with the computer specs provided. Besides, if it is possible to get an upgrade to 1500W power supply instead of 1200W, or can we purchase without a power supply?

We specialize in Forensic Computers for the Military and law enforcement and is currently looking to purchase the NA255A-XGPU. The followings are the PC specs and requirements: Host PC:

  • Motherboard: ASUS X99-E WS/USB 3.1 Socket 2011-v
  • CPU: i7-5820K 3.3GHz
  • RAM: 32GB DRR4 2133MHz
  • PCIe Slots: 7 x PCIe 3.0/2.0 x16 (single x16 or dual x16/x16 or triple x16/x16/x16 or quad x16/x16/x16/x16 or seven x16/x8/x8/x8/x8/x8/x8)
  • Windows 10 Pro 64-Bit

or

  • Motherboard: ASUS Z10PE-D8 WS Socket 2011-v3
  • CPU: 2x Intel Xeon E5-2630v4
  • RAM: 64-128GB DRR4
  • PCIe Slots: 7x PCIe 3.0
  • Windows 10 Pro 64-Bit

GPUs to be installed in the NA255A-XGPU are 4 x GTX 980 or 4 x GTX1080. For your reference, we had provided a real case with a similar scenario as yours: A customer installed four Nvidia GTX 980 GPU cards in his NA255A. The host computer he uses is Asus X99-E WS motherboard installed with Intel Core i7-5960X CPU; he installed eight 8GB DDR4 RAM modules on the motherboard, so totally there’re 64GB RAM on his Asus X99-E WS. The customer reports the four GTX 980 cards in NA255A work properly with Asus X99-E WS. We have confirmed the above setup from the customer is workable. However, you mentioned the CPU you used for the Asus X99-E WS/USB 3.1 motherboard is i7-5820K. But from our success case, the CPU used on Asus X99-E WS is a higher end model of i7-5960X. Please note that the max number of PCIe lanes for i7-5820K is only 28 lanes, but the max number of PCIe lanes for i7-5960X is 40 lanes. (1) i7-5820K: http://ark.intel.com/products/82932/Intel-Core-i7-5820K-Processor-15M-Cache-up-to-3_60-GHz (2) i7-5960X: http://ark.intel.com/products/82930/Intel-Core-i7-5960X-Processor-Extreme-Edition-20M-Cache-up-to-3_50-GHz Furthermore, your RAM for Asus X99-E WS/USB 3.1 motherboard is 32GB DDR4, but, from our success case the RAM is 64GB DDR4. The size of RAM on the motherboard may also have an influence on the number of GPU cards workable with motherboard. Therefore, four GTX 980 GPU cards in NA255A should also work with your Asus X99-E WS/USB 3.1 motherboard. But most importantly, the CPU model and size of RAM must be considered since the i7-5820K CPU only has 28 lanes and motherboard only has 32GB in size. As we mentioned, the ASUS X99-E WS can support up to 4 GPUs; however, the Z10PE-D8 WS can only recognize up to 2 GPUs. We suggest to choose the GTX-1080 because this GPU requires less power and offers better performance. Currently we don’t have the 1500W power supply option available. And due to its elaborate design, we don’t recommend using any different power supply other than the one included in the case.

I'm looking to use NA255A-GPU for heavy multi-GPU computational purposes. Is the Host Adapter PCIe card that plugs into the host PC a simple "data pass through" layer?

Does it add any additional latency when transferring large amounts of data between GPUs and host system memory? Is the upstream port slot inside of the NA255A box a special slot? Or is it a standard PCI-E slot? If I were to connect the Host Adapter card to a custom backplane not manufactured by you guys, say a backplane with a custom FPGA, does that custom backplane and FPGA still get recognized by the Host PC’s bios? I only ask because: 1. The entire system is very attractive for what we do here at Zebra. We do a lot of GPU intensive computations and your product’s ability to give us 4 GPUs in a single box is very attractive. 2. We have custom FPGAs and backplanes with both our static and dynamic holographic display products. We currently connect to these using much lower bandwidth protocols (ex: ethernet and USB). I’m curious if it would be possible to use your Host Adapter card to connect directly to our custom FGPA cards or backplanes so they are directly accessible to the host PC.   Answer:  The NA255A is a standard multiple PCIe slots expansion enclosure. It only require a free PCIe x16 slot from the host PC and doesn’t need any software installation for the enclosure itself. Of course, if the third-party’s PCIe cards that to be installed into NA255A require driver installation then the driver installation procedure is just the same as you plug the PCIe card into your host PC. So, the NA255A is a “data pass through” PCIe slot expansion. Just imaging the NA255A let your single PCIe slot of host PC to be multiple PCIe slots. The upstream slot is pre-installed with a target PCIe adapter in order to connect with the host adapter board of the host PC. If the FPGA is also a standard PCIe interface that can be installed into a standard PCIe slot of the host PC then it can also be installed into any expansion slots of NA255A as well but not in the slot of upstream port.

For the 1200 W model, would those cards work? The first claims 280 W, the second 250 W. While 4*280 < 1200, I am concerned about transients if the load varies a lot.

Yes, it can run 280W power supply *4.

Is this chassis designed to only support air cooled GPUs or is there enough room to install a closed loop liquid cooled card in this chassis?

There is enough room to install two closed loop liquid-cooled graphics cards in the NA255A chassis, and it requires an additional metal bracket to be attached (fastened) to the inner top of the NA255A chassis for the radiators.

Is the NA255A compatible with the motherboard MSI X99A SLI PLUS on a host computer?

We have tested NA255A with major PC motherboards from Asus, Gigabyte, and MSI…etc., and the PC Motherboards work  seamlessly with the Netstor NA255A enclosure, so MSI X99A SLI PLUS motherboard should also work all right with the NA255A.

For a Nvidia GTX 1080 TI graphics cards that uses primarily with OTOY Octane Render, can this also work with NA255A?

When Nvidia GTX 1080 Ti card installed directly on the PC motherboard, and under this circumstance if the OTOY Octane Render works properly with the Nvidia GTX 1080 Ti card installed directly on PC motherboard, it will also mean as GTX 1080 Ti card installed in NA255A connecting to the PC motherboard, the OTOY Octane Render works fine with the GTX 1080 Ti card in NA255A.

NA211A

I'm interested in purchasing the NA211A-GPU PCIe expansion chassis for my 2009 Mac Pro computer. I need it specifically for the DaVinci Resolve software, which relies heavily on GPU Cuda core processing. I plan to use the chassis for a second processing card, as well as a Red Rocket card. Is there any reason why the expansion chassis would not work with Resolve?

The DaVinci Resolve definitely works with the NA211A-GPU PCIe expansion chassis. However, you would not be able to install both the GPU card and a Red Rocket into the NA211A-GPU at the same time as the NA211A-GPU has only one open type PCIe x8 slot available for the PCIe x16 card. We would suggest that you install the GPU card and a PCIe x4 card (moved from your Mac Pro) in the NA211A-GPU, and keep the Red Rocket card in your Mac Pro for best performance. Please take note that either one of the following combinations of PCIe cards would work in the NA211A-GPU. a) 1 x GPU card 1 x low speed PCIe x4 card b) 1 x Red Rocket 1 x low speed PCIe x4 card We would recommend the NA250A-GPU (/product/pcie-expansion-enclosure-na250a/) should you need to install two or more PCIe x16 cards at the same time.

How to convert the NA211A to Thunderbolt PCIe expansion enclosure, NA211TB?

The following video link demo how to convert the NA211A to Thunderbolt PCIe expansion enclosure, NA211TB. http://www.netstor.com.tw/_05/video/NA211A%20into%20NA211TB.html

The description states that PCIe 3.0 x4 slots will be available when upstream port working under PCIe 3.0 x8 mode. Does this mean that if I am running at PCI-e 3.0 16x mode I will not have access to the PCIe x4 connectors?

If the upstream is running under PCIe 3.0 x16 mode then the two PCIe x4 connectors will not be available. The maximum bandwidth that host interface can support is up to 128 Gbps external PCIe 3.0 x16 between host and NA265A.

Does NA221A-NB (Laptop Package) work with Lenovo T530 Laptops running Windows 7 64-bit?

NA221A-NB works with laptops that come with ExpressCard 34/ 54 slot. For older laptops that support only PCIe 1.0 ×1 spec, the bandwidth is up to 2.5 Gbps (2.5 Gbps from 1.0 × one lane = 2.5 Gbps) when NA221A-NB is connected with the laptop. However, for newer laptops with Intel Sandy Bridge micro-architecture (w/ PCIe 2.0 ×1 spec), the bandwidth will be 5 Gbps (5 Gbps from 2.0 × one lane = 5 Gbps) when you connect NA221A-NB to the laptop.

Will the NA211A-DT connect with a 2.0 x4 PCIe slot via a x4 Riser cable? The riser cable is shielded and about 10" in length

It depends on the signal quality of Riser card. If the signal is in a good quality then the host adapter from NA211A-DT still can convert the connection between host computer to NA211A.

Will the NA211A-DT TurboBox work connected to a 2.0 x4 PCIe slot via a x4 Riser cable?

It depends on the signal quality of the Riser card. If the signal is in a good quality then the host adapter from NA211A-DT still can convert the connection between host computer to NA211A.

Can I install the Elgato H60 PRO to the NA211A PCi Enclosure?

The Elgato HD60 PRO is completely compatible with the NA211A.

I have a Power EdgeR630. On the first powering up, PC had no problem to interface with devices in the NA211A box. If rebooting the PC afterwards without powering done NA211A, PC's BIOS hung on "Initializing PCIe" stage. The only solution is to power down NA211A first, and then, power up PC. Could the solution be on the BIOS setting?

  1. There are three PCIe slots as SLOT3, SLOT2 and SLOT1 on the board within the Netstor chassis as shown in the attached Image below.
  2. Now remove (uninstall) all the third-party PCIe cards originally installed on SLOT3, SLOT2 and SLOT1 on the board within NA211A. [The external PCIe x4 interface target card must be remained at SLOT4]
  3. Connect NA211A to Dell R630 server by the external PCIe x4 data cable.
  4. Power on NA211A first and then power on R630.
  5. After Dell R630 fully boots into operating system, reboot the R630 server. Then check if the original situation ‘PC’s BIOS hung on “Initializing PCIe” stage’ still occurs or no longer exist.

For further information please contact us.  

NA381TB3

I would like to use the NA381TB3 on a Linux Server IBM 3650. Is there any path that we can upgrade/reconfigure our existing box to use our disk storage array on our linux server?

You can change the Thunderbolt interface to external PCIe interface as the attached external PCIe storage.

You need to purchase the kits as the following three lists.

 

NA960AG3-H for Host

NA960AG3-T Installed for NA381TB enclosure to replace Thunderbolt card.

AAML6815  – PCIe cable for connection between NA960AG3-H and NA960AG3-T

I currently have 2 NA381TB3 and have found an issue when copying specific files form the raid. It crashes the Thunderbolt BUS on my host Macbook Pro.

This problem is caused from the Apple adapter firmware. Since Apple doesn’t provide new firmware. This can be solved by upgrading NA381TB3’s Firmware. Currently the firmware of Netstor Thunderbolt 3 card in the NA381TB3 should be an earlier version. Please contact us directly in order to give you instructions on reverting the NA381TB3 to an earlier version.  

Do you have versions of the hard drive backplain board (looks like part number NS310SBP - see attached image) with pin 3 lifted, or do you have modification instructions for lifting pin 3 with the current boards? I only need to replace 2 hard drive back plains, not the full 5.

SAS 12Gb drives with SAS 3.0 standard and SATA 6Gb drives with SATA 3.3 standard define power connector pin3 as Power Disable Pin,but pin1-3 was defined for 3.3V input in older standards. If the backplane power connector provides 3.3V to pin3, it will disable the power of the hard drive and result drive not spin up. Our older backplane provides 3.3V, so these drives will not spin up. Two possible solutions for this case: 1. Paste a tape on the hard drive SAS connector (P1~P3) to block power down control feature, because we do not use this feature. 2. Modify the backplane to remove 3.3V power feature. you can contact with your original supplier for backplane rework assist.

NA210A

What is the bandwidth provided when TurboBox NA210A is connected with a laptop or a desktop PC?

The TurboBox NA210A is PCIe 2.0 spec, providing throughput 5 Gbps per lane. For desktop PC users, since both host card and target card are PCIe 2.0 ×4 spec, when TurboBox NA210A is connected with desktop PC, the bandwidth provided is 20 Gbps (5 Gbps × 4 lanes = 20 Gbps). For laptop users, since current technology of laptop supports only PCIe 1.0 ×1 spec, when TurboBox NA210A is connected with laptop, the bandwidth is 2.5 Gbps (2.5 Gbps from PCIe 1.0 × one lane = 2.5 Gbps). However, after the release of laptop with PCIe 2.0 ×1 spec (Intel Sandy Bridge microarchitecture) in the first quarter of 2011, when TurboBox NA210A is connected with laptop, the bandwidth will be 5 Gbps (5 Gbps from PCIe 2.0 × one lane = 5 Gbps).

How do I know the third party PCIe cards plugged on TurboBox NA210A are recognized by computer?

For users of Windows operating system, please check “Device Manager” from Computer Management. As for users of Mac OS X, please check “About This Mac” under the Apple icon to see if the third party PCIe cards are recognized by computer. For detailed information about the verification of third party PCIe cards, please check the user manual and see the ninth section “Verify Installation” at the third page of the user manual.

After I connect the TurboBox NA210A to laptop/desktop PC, the TurboBox can not be recognized by computer. What can I do to solve this problem?

If the TurboBox NA210A is not recognized by computer, it can be BIOS’ problem. Please update your laptop/desktop PC to the latest BIOS from the Web site of your laptop/desktop PC manufacturer. After updating the laptop/desktop PC to the latest BIOS, the TurboBox can be recognized by computer.

Wondering if your Model# NA210A can support a KONA 3 and/or Red Rocket card(s)? I want to use this with a MacBook Pro.

Only MacBook Pro(Unibody Model ID 5,1) has problem on its ExpressCard interface compatibility; others models of MacBook Pro are working well with NA210A. The spec. of Red Rocket card(s) is no problem working with NA210A but the spec. of KONA seems to ask for PCIe x4 bandwidth. Since Laptop is only provide PCIe x1 bandwidth so when KONA 3 works with a Laptop then I suppose it cannot reach full performance. SD will work but I cannot make sure on HD.

My system is: Macpro (8-core) 2x2.8 Quad intel Xeon. I am using Protools Accel cards a total of three PCie cards are already installed and a video card a total of 4 slots. I need to use the video card inside the expansion box so i can use the slot for the host card. I will be using a UAD card inside the expansion box and one video card. Would this be possible?

Yes, NA210A is no problem working both Video and Audio cards and the bandwidth from DT will be fairly enough for handle those two cards together. UAD’s engineer has tested NA210A with their 2pcs of UAD-2 Duo and the result is workin well. UAS will announce this news after they finish their big project of new products.

I'm running a mac pro 2.66ghz quad core intel nehalem processor with 16gb of 1066mhz ddr3 ram. The mac OS is 10.6.6. I want to run the NA210A-L (DT) loaded with two UAD 2 quad cards and a Sonnet tango express card, or quite possibly, three of the UAD2 quad cards.

Yes, it is workable. UAD’s engineer has tested NA210A-L(DT) with 3* UAD2 Duo cards and the result will be announced on UAD’s website soon.

NA220A

What is the bandwidth provided when NA220A is connected with a laptop or a desktop PC?

The NA220A comes with PCIe 2.0, providing throughput of 5 Gbps per lane. For desktop PC users, since both host card and target card are PCIe 2.0 x4 spec, when NA220A is connected with desktop PC, the bandwidth provided is 20 Gbps (5 Gbps x 4 lanes = 20 Gbps). The older version of laptops only support PCIe 1.0 x1 spec, when NA220A is connected with laptop, the bandwidth is 2.5 Gbps (2.5 Gbps from PCIe 1.0 x one lane = 2.5 Gbps). However, after the release of laptop with PCIe 2.0 x1 spec (Intel Sandy Bridge micro architecture) in the first quarter of 2011, when NA220A is connected with laptop, the bandwidth will be 5 Gbps (5 Gbps from PCIe 2.0 x one lane = 5 Gbps).

Does the NA220A support the: UAD-2 QUAD DSP Accelerator?

Yes, NA220A works with UAD-2 QUAD. Moreover, UAD-2 QUAD only consumes 10W , and the NA220A is providing 80W output power which is sufficient.

Do the power supplies support PFC?

Yes, the power supply supports active PFC.

What temperatures do the GPUs and/or the system board reach when run for extended periods?

The maximum temperature depends on the type of GPU cards you are using.

NA265A

Can a single host CPU system support more than one NA265A-XGPU-R?

The amount of GPU cards that can be recognized by the system is dependent on the host’s PCIe resources. For Windows, the amount may be around 4 or 5. In a Linux system, it can recognize more GPU cards.

Can I connect a server through a PCIe 3.0 Interface to 4 GTX 1080TI GPUs located in the NA265?

Most the motherboard systems can recognized over 4 GPUs but till have few cases that the PCIe resources design were shortage by the motherboard designer which only can recognize only 3 GPUs so it depends if the PCIe resources are sufficient or not. It means that it’s not related to NA265A.

What PCIe switch is used on the NA2654?

The PCIe switch used on NA265A is Broadcom PEX 8747.

NA221A-G3

Does the NA221A have a built in AC plug or does it use an external PS brick?

The AC plug for NA221A uses an external PS brick.

What is the power capacity of the PSU?

The power supply is 300W

Does the NA211A-G3 accept one or two 3.5" hard drives?

We no longer have a version that fits 3.5″ hard drives available since all of the PCIe 2.0 versions were discontinued.

Can the case / power supply handle a full size GPU?

For the NA211A-G3, the maximum PCIe GPU card clearance is 315mm x 120mm. 

Does the NA211-G3 need a software driver for Linux OS?

NA211A-G3 itself is a PCIe expansion chassis that extends PCIe 3.0 signal from one slot on computer to three PCIe 3.0 slots for use; therefore, NA211A-G3 itself doesn’t need any driver on any platform of Linux, Windows, and macOS.

As third-party PCIe cards installed in NA211A-G3 connecting to computer running Linux, only the third-party PCIe cards in NA211A-G3 will require the Linux driver for the Linux OS.

I want to expand the PCI slots on my Macbook Pro. What is the optimal setup for the Netstor NA211A-G3 in which to do so?

Given the following two setup options, which would be the most optimal?
OPTION 1:

PCI 1: Nvidia Geforce GTX Titan X 12Gb

PCI 2: OWC Accelsior Pro Q 2T

PCI 3: Sonnet allegro pro usb 3.0 4-port

PCI 4: NETSTOR host Card

NETSTOR

SLOT1: Nvidia Geforce GTX Titan X 12Gb (will the PSU power be enough from NETSTOR?)

SLOT2: BM Decklink 4K monitor

SLOT3: OWC Accelsior + SSD Angelbird 500Gb

 

OPTION 2

PCI 1: Nvidia Geforce GTX Titan X 12Gb

PCI 2: Nvidia Geforce GTX Titan X 12Gb (external PSU, it’s already installed for the first GPU)

PCI 3: Sonnet allegro pro usb 3.0 4-port

PCI 4: NETSTOR host Card

NETSTOR

SLOT1: OWC Accelsior Pro Q 2T (not sure if transfer speed will be slowdown because PCI3.0 x4)

SLOT2: BM Decklink 4K monitor

SLOT3: OWC Accelsior + SSD Angelbird 500Gb

The “option 1” won’t be workable because when you install a GPU card with dual-width then it will be occupied two expansion slots. Therefore, NA211A-G3 can only install up to 2 cards. ‘Option 2’ would be the optimal choice to meet your demands. A third option can also be used, in which you would use the Netstor NA255A then you can get maximum performance and you don’t need to worry the power supply for GPU card as well.  The following setup is the optimal layout for the NA255A should you choose to upgrade.

OPTION 3 

PCI 1: Nvidia Geforce GTX Titan X 12Gb

PCI 2: Nvidia Geforce GTX Titan X 12Gb (external PSU, it’s already installed for the first GPU)

SLOT3: OWC Accelsior Pro Q 2T

PCI 4: NETSTOR host Card

NETSTOR

NA65A-XGPU-R

Is the 1350 watt redundant power supply the the sum of both power supplies?

It is the sum of both however, if one module malfunctions, the other can support 1350 watts. While both modules are running it will still only support 1350 watts.

At what efficiency do the power supplies run and/or do they meet certain 80 Plus certification levels?

No. The power supply is not 80 Plus certified

NA381TB

We would like to check the compatibility between the NA381TB and the ARC-1264IL-16 RAID Controller card. We already have the RAID card on hand and we understand that it’s a 16 channel card while the enclosure has 24 drive bays.

ARC-1264IL-16 RAID card is compatible with NA381TB (24-bay Thunderbolt 2 JBOD) and work with Thunderbolt-enabled Mac. Please take note that ARC-1264IL-16 RAID card can only support 16 bays in the Netstor 4U 24-bay NA381TB enclosure. Please go to http://www.areca.com.tw/support/s_macos/macos.htm and download/ install the latest MRAID program on your Thunderbolt-enabled Mac in order for the ARC-1264IL-16 RAID card to work with NA381TB and Mac OS X.  

What is the read/write benchmark information for either of these two units? What is the normal life span of using 2.5" drives in a RAID environment?.

We don’t have these information yet. But performance and life span will be different when using different host RAID card.  

Is it possible to use this storage array on a Linux Server?

In order to use this on a Linux Server, you must change the Thunderbolt interface to external PCIe interface as the attached external PCIe storage.

You need to purchase the kits as the following three lists:

NA960AG3- H for Host

NA960AG3- T Installed for NA381TB enclosure to replace Thunderbolt card.

AAML6815- PCIe cable for connection between NA960AG3-H and NA960AG3-T

We use our NA381TB for data recovery and we have it's disks out of the enclosure. Since all the disks are numbered and the disks are running RAID 6, where are disk 1 and 2 supposed to be place in the order?

For the design of Thunderbolt 2 NA381TB storage, it allows users to choose their own RAID card to be installed in NA381TB storage enclosure for work.

As Thunderbolt 2 NA381TB is a 24-bay storage, users can choose the RAID card with six SFF-8087 mini-SAS ports such as HighPoint RocketRAID 2760A card, and Areca ARC-1882-ix-24 card…etc. for usage with the Netstor enclosure.

The disk order will be related to the RAID card that is chosen to be used with the NA381TB. There are six SFF-8087 mini-SAS ports on the RAID card. By each brand, model of RAID card, the order of the six SFF-8087 mini-SAS ports on the RAID card is different. For some brand, model of RAID card, the order is disk 1 through disk 24 from bottom SFF-8087 port to top SFF-8087 port while for some other brand, model of RAID card, the order is disk 1 ~ disk 24 from top SFF-8087 port to bottom SFF-8087 port. Therefore, now we have to verify which brand, model of RAID card the user uses inside his Thunderbolt 2 NA381TB storage.

Does the ARC-188ix-24-8NC work on the NA381TB3?

The ARC-1883ix-24 is usuable in the NA381TB3 but the internal cable should be changed to SFF8087 (for backplane) to SFF8643 (for RAID card).

NA332A

Our system only supports PCIe-x4 speed on our host system's PCIe-x8 slot and I need a replacement for the NA332A. Is there any alternative for the NA332A?

We are currently upgrading all of our PCIe 2.0 expansion chassis to PCIe 3.0. Unfortunately, the NA332A is no longer supported. An alternative to this is the updated, NA333A system. Both the NA333A and NA332A’s host adapters come with a PCIe x8 speed. If your host computer only supports PCIe x4 speed on a PCIe x8 slot, as long as the host adapter card can fit the PCIe x8 slot in your system, it should work fine (just at reduced bandwidth).

NA611TB3

Does data transfer speed depend on the type of SSD card being used?

NA611TB3 40Gbps bandwidth is including data and video. For data, the maximum bandwidth is 2600MB/s.

When through Thunderbolt, the Thunderbolt bottleneck will reduce the Write performance a lot. So, the manufacturer suggests an NVMe selection for Thunderbolt better choose the performance under the Thunderbolt bottleneck such as RD400 from OCZ or XG3 or 5 from Toshiba.

Is there any specification performance for the NA611TB3 with a new Samsung 970 PRO M.2 2280 1TB?

Firstly, please refer to the attached Image_1.jpg; the spec of Samsung 960 PRO NVMe M.2 2280 1TB SSD is read 3500 MB/s, and write 2100 MB/s.

For dual Samsung 960 PRO NVMe M.2 2280 1TB SSDs (RAID 0) in NA611TB3 working with the Thunderbolt 3 computer, the read performance is about 2400 MB/s and the write performance is around 1250 MB/s; the data are in the below weblink:

http://www.netstor.com.tw/faq_info.aspx?page=1&id=7

On the other hand, please refer to the attached Image_2.jpg, for the spec of Samsung 970 PRO NVMe M.2 2280 1TB SSD, the read is the same as 960 PRO as 3500 MB/s, and the write is 2700 MB/s which is 600 MB/s more than 960 PRO.

Therefore, it could be speculated for dual Samsung 970 PRO NVMe M.2 2280 1TB SSDs (RAID 0) in NA611TB3 working with the Thunderbolt 3 computer, the read performance might still be identical as around 2400 MB/s and the write performance should be higher than 1250 MB/s because single 970 PRO’s write is higher than single 960 PRO’s write.

So far we haven’t got the chance to test Samsung 970 PRO NVMe M.2 2280 1TB SSDs in NA611TB3 working with TB3 computer, but once we or our partners have got the chance and have tested 970 PRO M.2 SSDs in NA611TB3 working with Thunderbolt 3 computer in the future and have the test performance result, we will let you know the information immediately.

I have two M.2 NVMe 1TB cards I would need to format as RAID 0 in order to have 2TB, will High Sierra do that and use APFS?

Yes, you can use macOS High Sierra’s Disk Utility to format the two M.2 NVMe 1TB cards as RAID 0 in order to have 2TB and use the RAID 0 as APFS.

Click download tab, click on User Manual, then go to page 11 of the user’s manual for the instruction.

If I have one 2TB card, can I assume it would use APFS without question? Bootable? Performance? what kind of speeds comparisons can I expect with these different configurations?

Yes, if you have one 2TB card, it will be able to be used as APFS without question. For the performance and the speeds comparisons, please go to the following webpage:

On the TB611TB3, how do the two or four channels of PCIe work?

Each M.2 PCIe NVMe SSD within NA611TB3 is given with PCIe 3.0 x2 bandwidth, and, yes, it is correct that it will significantly increase the speed benefit of RAID 0. The RAID 0 speed can be seen at the following site (the last row in the chart):

I am using an "OWC Mercury Accelsior E2 PCI Express SSD" with two M.2 blades in my 2009 Mac Pro and will be replacing with a new iMac Pro. Are the M.2 Blades compatible with the Netstor NA611TB3?

The two M.2 blades on your  OWC Mercury Accelsior E2 PCIe SSD card are M.2 SATA interface and not M.2 PCIe NVMe interface.

NA611TB3 storage only accepts M.2 PCIe NVMe interface SSD, and is not compatible with M.2 SATA interface SSD. Therefore, if you move the OWC M.2 SATA blades from your Mercury Accelsior E2 PCIe SSD card into NA611TB3, those M.2 SATA blades will not work with the NA611TB3.

Please refer our Compatibility list to find the M.2 PCIe NVMe SSDs that are compatible with NA611TB3 in your Thunderbolt 3 iMac Pro.

I have a single Module Samsung 960 Pro m.2 NVMe SSD with a MacBook Pro 10.12.6 and the drive does not mount nor does the disk utility show the new drive at all. How can I solve this problem?

In order to support M.2 PCIe NVMe SSDS, the NA611TB3 is only compatible with MacOS High Sierra 10.13.0 and later versions. Please update MacOS X to the latest version on your system and the M.2 PCIe NVMe SSD(s) in your NA611TB3 storage should then be detected. In addition, NA611TB3 can not only work with only one M.2 PCIe NVMe SSD module, but can work with up to two seperate M.2 PCIe NVMe SSD modules.

Will the Samsung 860 EVO Series M.2 2280 2TB work with the NA611TB3?

The Samsung 860 EVO SATA M.2 2TB SSD is an M.2 SATA SSD.

Please refer to the attached image from NA611TB3 site’s specifications. It shows only M.2 PCIe NVMe SSD can be used with the NA611TB3 storage, therefore, the Samsung 860 EVO SATA M.2 2TB SSD will not work with NA611TB3 storage because 860 EVO is an M.2 SATA SSD rather than M.2 PCIe NVMe SSD.

Click on the ‘Compatibility’ tab, and you can see the current M.2 PCIe NVMe SSDs for Netstor Thunderbolt 3 NA611TB3 storage.

I’m looking to use the NA611TB3 to retrieve data off a M.2 NVMe SSD (Item# “SD9PN9U-512G-1012”). Will this work?

Yes, the NA611TB3 storage will allow you to retrieve the data off the SanDisk SD9PN9U-512G-1012 M.2 PCIe NVMe SSD in NA611TB3 over Thunderbolt 3 interface similar to the process on a thumb drive based on the condition that your SanDisk SD9PN9U-512G-1012 SSD is with NTFS format.

Since the SSD M.2 PCIe NVMe was run with Windows 10 Pro within the Dell XPS laptop, the file system of the SSD should be NTFS (New Technology File System) format. You can help double check whether the file system of your SSD is with NTFS format.

Based on the information described above, if your SSD is confirmed to be with NTFS format, when installed in NA611TB3 and connected to Dell  XPS laptop running Windows 10, the SSD [SD9PN9U-512G-1012] in NA611TB3 should be able to work and retrieve data

The working theory is: any M.2 PCIe NVMe SSD can work within inside one laptop or desktop computer, the same as an SSD will also work with a Thunderbolt 3 laptop/desktop computer via the Thunderbolt 3 interface.

Unless the SSD is old (year 2016) or in bad condition (wore out or damaged), It will work with TB3 computer via TB3 port.

Can you confirm the power consumption (Watts) at idle would be low with no Data activity or fan is this correct if the power consumtion states DC Output:+12V/5A, 60W in specs?

Yes, when the NA611TB3 is at idle, the power consumption will be low with no data activity and fan. As the NA611TB3 is at idle, the power consumption will only come from the two installed M.2 NVMe SSDs at idle status, the backplane and the Netstor unit’s internal low power 2×2 cm fan.

I will connect your NA611TB3 - Thunderbolt™ 3 NVMe SSD Storage to the Mac Mini thru the Thunderbolt 3 (USB-C) port. I had read the unit uses 2 pci lanes. What transfer speed could I expect for one card installed?

When only one Samsung 970 EVO M.2 1TB SSD is installed within the NA611TB3 storage, the maximum transfer speed will be up to 15XX ~ 1600 MB/s between NA611TB3 and the Thunderbolt 3 Mac because it is PCIe 3.0 x2 for one M.2 SSD within the Netstor unit.

Would the unit be bootable or need a Driver installed on the Mac. I may install the computers operating system on your NA611TB3

A driver is not required. You can install the macOS operating system on one M.2 SSD within NA611TB3 unit, and the one M.2 SSD in NA611TB3 can be the bootable drive for the Mac.

Does the NA611TB3 support Trim?

Trim is a technology from SSD. As long as the M.2 SSD itself does support the Trim feature, the NA611TB3 supports it.

Does the NA611TB3 support UASP?

NA611TB3’s internal Alpine Ridge controller does support downstream USB 3.1 Gen2 (10Gbps) protocol and the Alpine Ridge is fully compliant with USB 3.1 Gen2 (10Gbps) protocol that supports UASP.

NS370TB3

Do the NS370TB3 controllers use Areca Webgui software? I have an older Areca Model; will I be able to swap out the existing 4 HDD into this new unit?

Yes, you will be able to use your old HDD in the newest unit.

For testing, we used a mac mini(TB2) ==> Deivce(TB2) ==> Apple TB2 to TB3 converter ==> NS370TB3, and the result shows it works.

Therefore, you will need an Apple TB2 to TB3 converter as well.
