HP Introduces M.2 SSDs for Blade Servers

HP M2 Solid State Enablement Kit for BladesHP 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 (see below for details.)
