Q: Does the NS388P support SSD dual porting?

A: The NS388P storage (model: NS388P-D2) supports U.2 PCIe NVMe 3.0 2×2 dual port 2.5-inch SSDs including Techman XC120, Intel SSD DC D3600 series and Intel SSD DC D3700 series…etc.

On the other hand, the other NS388P storage model ‘NS388P-S4’ only supports U.2 PCIe NVMe 3.0 x4 single port 2.5-inch SSDs such as Intel Optane SSD 900P series, and does not support U.2 PCIe NVMe 3.0 2×2 dual port 2.5” SSD. [Last update Jan 31, 2019]

[dt_gap height=”10″ /][dt_divider style=”thick” /][dt_gap height=”10″ /]

Q: Does a fine Thunderbolt cable need to connected before the NA762TB powers up?

A: Yes, a fine Thunderbolt cable needs to be connected to Netstor NA762TB storage in the very first beginning before everything powers up. [Last update Jan 31, 2019]

NA762TB3

[dt_gap height=”10″ /][dt_divider style=”thick” /][dt_gap height=”10″ /]

Q: Does the Nestor NA762TB3 Desktop 8 Bay Thunderbolt 3 RAID Storage device have a storage capacity limit for the hard drives used within the device’s bays?

A: The capacity limit for one HDD to be used in NA762TB3 depends on the RAID controller within the NA762TB3 storage.

The NA762TB3 uses Areca ARC-1224-8i RAID controller inside. I have visited Areca’s website site and have downloaded the latest Areca HDD compatibility matrix for the ARC-1224-8i RAID controller; please see the attached PDF.

Now for ARC-1224-8i RAID controller, the max capacity the ARC-1224-8i can support for one HDD (Seagate ST14000NM0018) is up to 14 TB; therefore, the NA762TB3 storage can support one HDD (Seagate ST14000NM0018) up to 14 TB.

So users can use eight (8) Seagate ST14000NM0018 HDDs in NA762TB3; when the eight 14TB HDDs in NA762TB3 are set up with a RAID 0 volume, the total capacity the users can use is 112 TB. [Last update Jan 31, 2019]

Q: Is the Nestor NA762TB3 Desktop 8 Bay Thunderbolt 3 RAID Storage device compatible with hard drives of this storage capacity (ie. 14T)?

A: Yes, the NA762TB3 can use HDD of 14 TB. As mentioned in the above point one, from Areca’s ARC-1224-8i HDD compatibility matrix PDF as the attached, Seagate ST14000NM0018 14TB HDD is supported. Because NA762TB3 uses ARC-1224-8i RAID controller inside, NA762TB3 can use Seagate ST14000NM0018 14TB HDD. [Last update Jan 31, 2019]

Q: Should the Nestor NA762TB3 Desktop 8 Bay Thunderbolt 3 RAID Storage device have a technical problem with one of the bays, what is the repair processes?

A: If the NA762TB3 has a technical problem with one of the bays, the repair process will be to apply for the RMA process with Netstor Technology Corporation in Taiwan via the distributor DynapowerUSA. The component/NA762TB3 can be sent back to Netstor Taiwan for fixing/repair; after the component/NA762TB3 is repaired, the component/NA762TB3 will be returned to the customer.

NA381TB

[dt_gap height=”10″ /][dt_divider style=”thick” /][dt_gap height=”10″ /]

Q: I have the original Thunderbolt 1 NA381TB that is about 5 years old. I wish to upgrade its functionality and use it with a 2019 (Thunderbolt 3) Mac Mini that is also being upgraded after 5 years of operation. Can I upgrade the Thunderbolt1 interface with a Thunderbolt2 interface card and use an Apple Thunderbolt 2 to Thunderbolt 3 adapter? Can I upgrade Thunderbolt1 interface with a Thunderbolt3 interface card? Lastly, should I totally replace the NA381TB with a Thunderbolt3 NA381TB3?

A: The Thunderbolt 1 (10 Gbps) NA381TB can work with Thunderbolt 3 Mac mini (Late 2018 model) directly via the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

The Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter also supports Thunderbolt 3 (40 Gbps) to Thunderbolt 1 (10 Gbps) work. Therefore, you can have the following topology for work:

Thunderbolt 3 Mac mini (Late 2018 model) >> Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter >> Thunderbolt cable >> Thunderbolt 1 (10 Gbps) NA381TB

Note that Thunderbolt 2 (20 Gbps) and Thunderbolt 1 (10 Gbps) are basically the same; they share the same Thunderbolt cable. The only difference is Thunderbolt 1 (10 Gbps) uses Light Ridge controller, and Thunderbolt 2 (20 Gbps) uses Falcon Ridge controller. TB2 and TB1 are fundamentally the same.

Netstor’s Thunderbolt 2 card is End-of-Life (EOL). Netstor don’t manufacture Thunderbolt 2 card since early 2017, so it’s impossible for Netstor to sell the Thunderbolt 2 card.

If a user installs a Thunderbolt 3 card in Thunderbolt 1 (10 Gbps) NA381TB to replace the original TB1 card, the Thunderbolt 3 card in Thunderbolt 1 (10 Gbps) NA381TB can only run PCIe 2.0 (5 Gbps) instead of PCIe 3.0 (8 Gbps), so the bandwidth to the Thunderbolt 3 host computer will still be the same speed as Thunderbolt 2.

Note Thunderbolt 3 is PCIe 3.0 x4 for 2750 MB/s and Thunderbolt 2 is PCIe 2.0 x4 for 1375 MB/s.

The reason that the Thunderbolt 3 card in Thunderbolt 1 (10 Gbps) NA381TB can only run PCIe 2.0 (5 Gbps) instead of PCIe 3.0 (8Gbps) is because the backplane within Thunderbolt 1 (10 Gbps) NA381TB is PCIe 2.0. [Last update Jan 31, 2019]

Q: 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.

A: 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. [Last update Jun 28, 2016]

NS388S-SE/ NS330S-8028

[dt_gap height=”10″ /][dt_divider style=”thick” /][dt_gap height=”10″ /]

Q: Does the NS388S provide enough resource/function to allow user to use a zone mode to split the JBOD into two zones to be used by two separate servers?

A: Yes, the NS388S storage can allow the user to use zone mode to split the JBOD into two zones to be used by two separate servers. [Last update Jan 31, 2017]

Q: 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?

A: We don’t have these information yet. But performance and life span will be different when using different host RAID card. [Last update March 19, 2017]
