i. SCSI Performance Test Conclusions i. SCSI protocol performance is only limited by the speed of the underlying bus and vendor implementation § i. SCSI is ready for mission critical performance workloads § Use Receive Side Scaling to optimize for i. SCSI performance in the host § Use VMQ/VMDq to optimize i. SCSI performance within the VM for best IO scaling § VLANs offers logical separation of LAN/SAN traffic and additional performance isolation § Most applications use moderate IO and throughput §

• • • Always use active/active multipathing load balance policies (round robin, least queue depth) vs. failover mode. Follow vendor guidelines for timer settings • Queuedepth, PDORemove. Period, etc. as these settings will have a direct impact on ability to deliver max IO to VMs and controlling failover times Many array vendors include host utilities that automatically adjust settings to optimize for their array • Example: Dell “hit kit” host integration kit Pay attention to spindle count for workload • SSDs (Solid State Drives) change the game on this For NICs used for i.
