We've recently deployed a Dell EqualLogic PS6210 SAN with an all-SSD configuration. This was connected to Dell Force10 MXL 10GbE switches to provide iSCSI storage to Dell PowerEdge blade servers.
The implementation was interesting, as the Force 10 switches had to connect back to an existing HP ProCurve network at the data centre core, and present iSCSI LUNs back to hosts on both Force10 and ProCurve ports.
The implementation was completed to schedule, including some unanticipated network design and configuration implementation, with no interruption to production services. The new iSCSI SAN was tested at over 125,000 read IOPS at 1ms response time - not bad!
