  • 35. Prior Barriers to Convergence iSCSI on Gigabit Ethernet best practices architected separate Ethernet network for iSCSI traffic – Servers - iSCSI on separate NICs – Switches – iSCSI on separate switches – Storage – iSCSI targets placed on separate network & switches Rationale – Congestion causes packet loss, creating non-deterministic performance – TCP/IP error recovery expensive from a predictable latency perspective In virtualized environments, best practices employ multiple NICs for traffic isolation (iSCSI, vMotion, production, management, etc.) – Enables effective bandwidth caps between services, ensures available bandwidth at server 35
  • 36. Enterprise iSCSI – Emulex, Dell, VMware Dell EqualLogic storage arrays and Emulex OCe11102 CNAs – Combined with a DCB enabled switch, provide the basis for the iSCSI over DCB model for ESX iSCSI supports 10GbE today, & does not require DCB, however… The same benefits apply to iSCSI as apply to FCoE – iSCSI over DCB provides a lossless environment – iSCSI has a built in mechanism to recover from dropped packets with TCP/IP, but eliminating the need for retransmits makes the host, network, and target more efficient and reduce CPU utilization iSCSI over DCB allows for more deterministic performance in the event of network congestion, and more headroom on the host to run more virtual machines This solution moves 10GbE iSCSI from a bandwidth bump (from 1GbE) to a truly robust iSCSI solution, ready for Enterprise SAN deployment 36
