HP M.2 SSDS FOR BLADE SERVERS
HP recently announced the industry’s first M.2 SSD for blade servers. If you’re not familiar with M.2 (pronounced M dot 2), it’s a small form factor card and connector supporting applications such as Wi-Fi, WWAN, USB, PCIe & SATA seen mostly in desktop / laptop systems.
Adoption of this form factor in Tier 1 vendors is slow coming, which is why this is a big announcement for HP. Since this plugs into the system board, it avoids traversing the SAS mid-plane and allows for connectivity to the system PCIe bus supporting faster speeds.
Key points to note:-
- The HP “M.2 Solid State Enablement Kit” is available in dual and single 64 GB capacity and is compatible with HP ProLiant Gen9 blade servers only.
- The HP M.2 SSD is supported by the HP Dynamic Smart Array B140i Controller using software RAID.
- Ideally, the HP M.2 SSD would provide a platform for booting the O/S, however if disks are required on the blade server, they will be controlled by a separate HP Smart Array Controller.
NOTE: There is a 120GB M.2 offering, however it is only for the HP ProLiant DL series. The BL series blade servers are limited to 64GB.
