Windows Server 8 to be storage-focused OS
It will offer RDMA over Ethernet and InfiniBand, should cut Patch Tuesday downtime, execs say

Computerworld - Microsoft executives said Windows Server 8, the beta of which is expected out in the next several weeks, is the most storage-focused OS release to date.

The new OS will support Hyper-V and SQL Server running over the Samba file sharing protocol Server Message Block (SMB) v2.2, including remote direct memory access (RDMA) over Ethernet and InfiniBand.

The new file-sharing capability allows a virtualized server infrastructure to utilize shared JBOD storage through the use of RDMA-enabled network interface cards (RNICs). To date, Microsoft has qualified one 10GbE NIC from Intel and a 10GbE and InfiniBand NIC from Mellanox Technologies.

RDMA allows servers, through special NICs, to access the memory of other servers without the use of the operating system, offering very high throughput, low latency networking for server clusters.

Jim Pinkerton, a partner architect in Microsoft's File Server Technologies development group, compared the ability to use RDMA over Ethernet or InfiniBand to that of the high-speed storage protocol Fibre Channel, in that a network interface card is used to offload network protocol traffic from a server's CPU.
