Late last year the NVMe standard was released and ever since then Supermicro have been releasing new Barebones, Chassis's and motherboards to support this new standard. If you haven't heard of NVMe before it standards for Non-Volatile Memory Host Controller Interface which is a specification for accessing SSDs attached through the PCI Express bus. Because of the direct connection to CPU and SFF-8639 connector it all translates into much higher transfer throughput, almost 3 to 4 times faster than what we get on SATA 3 6Gb/s. 

Supermicro now have good number of brand new bespoke NVMe SuperServers which are available now like the 6028U-TNR4T+ and 1028U-TNR4T+. These come with an option to add in 4 x HotSwapable NVMe drives. However what if you are not looking to replace your infostructure and would to upgrade you exisisting systems to NVMe? Well the the Supermicro AOC-SLG3-2E4 NVMe PCIe Add On card could be the perfect solution!


The AOC-SLG3-2E4 offers support for upto 2 x NVMe drives via the PCIe x8 Gen3 interface. The 2 NVMe drives will connect to the 2 x Mini-SAS HD (SFF-8644) connectors on the card. Currently only supports a max of two drives, you would be required to add in more cards if you wanted more than two NVMe drives per system. Please remember you will need a speific cable also - SFF-8643 to U.2 cable. 

Edit* The only downside is there is no HotSwap support this way. The drives will have to be installed internally. It is possible you can upgrade your chassis's backplane to an NVMe backplane to get HotSwap support but thats completely dependent on your SuperServer or Chassis.

There is also a PLX chip on board, an Avago PLX PE8718. This is there so 2 x NMVe drives can be connected at once. There is the slightly cheaper Supermicro AOC-SLG3-2E4R card but this does not include the PLX chip and so only works with certain motherboards, if you want to run 2 drives. 

Please see the slide below for full details of the card:


With one of these AOC-SLG3-2E4 add on cards combined with NVMe drives (we recommend Intels P3600 and P3700 Series SSD's) you easily be looking at sequential read speeds 4.2GB/s. 

The AOC card is available to purchase right now from us and come in at a very reasonable £110.00. Don't hestaite to get in contact with us if you require any more info on this product.
