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
