  34. 34. Emulex and VMware Emulex is a long-standing VMware partner – Early Community Source Partner – Pioneer in CIM Providers for ESXi, working collaboratively – Innovative Fibre Channel technologies such as NPIV vSphere in-box support and IOVP Certifications across Product Lines iSCSI 10GbE offload product support starting with ESX4.1 PVSP Listing on for Dell Equalogic / Emulex now! – See 34
  35. 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. 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
  37. 37. iSCSI over DCB with VMwareEnterprise iSCSI Hardware iSCSI VM1 VM2 VM3 VM26 Current versions of vSphere … App App App App OS OS OS OS don’t directly support DCB protocols – No APIs for a NIC to support DCBX and PFC HBAs/CNAs offload iSCSI, DCB Ethernet transparent to OS Switch – DCBX and PFC all handled by iSCSI device storage – Host to Device interaction all at SCSI layer PVSP certified 37
