This week I’ve delivered another smashing VMware vSphere Design Workshop :-) During the last day there was a great discussion about IP storage. Hans Booms who attended the workshop pulled out an overview of performance measurements he did on an EqualLogic PS6000XV iSCSI SAN. It’s configured as RAID 10 with 12*15K SAS disks, the ESX 4.01 host is configured with Round Robin and uses 4 NICs and IOmeter is running in a Windows 2008 virtual machine.
