Infiniband

reliability, and availability in scenarios where data is stored on file shares. Some of the new features and enhancements in SMB 3 include: ■ SMB Direct Enables using network adapters capable of Remote Direct Memory Access (RDMA) such as iWARP, Infiniband, or RoCE (RDMA over Converged Ethernet) that can function at full speed and low latency with very little processor overhead on the host. When such adapters are used on Hyper-V hosts, you can store VM files on a remote file server…

The first letter specifies the wavelength used: S = short, L = long, E = extra-long wavelength. The second letter specifies the PHY type: R = LAN PHY, W = WAN PHY.…

One of the most important statistics to monitor is the “Private Interconnect Transfer Rate (MB/Sec).” Make sure that the transfer rate is not close to the limit of transfer rate imposed by the network cards used for the Interconnect (1 Gig E, InfiniBand, and so on). For example, if we are using a 1 Gig E card, the theoretical transfer rate is approximately 125 MB/sec. Now, the practical transfer rate is around ~70 to 80 percent of that number, which will bring this rate down to approximately 87
