How DCB Makes iSCSI Better
March 5th, 2013A challenge with traditional iSCSI deployments is the non-deterministic nature of Ethernet networks. When Ethernet networks only carried non-storage traffic, lost data packets where not a big issue as they would get retransmitted. However; as we layered storage traffic over Ethernet, lost data packets became a “no no” as storage traffic is not as forgiving as non-storage traffic and data retransmissions introduced I/O delays which are unacceptable to storage traffic. In addition, traditional Ethernet also had no mechanism to assign priorities to classes of I/O.
Therefore a new solution was needed. Short of creating a separate Ethernet network to handle … Read the rest
