EqualLogic Performance.

We've recently implemented SQL 2012 With Database Availability Groups on VMWare and with Dell Equalogic PS series SAN utilising SSD/SAS auto tiering. The objective was to provide high availability and high performance SQL hosting for a clinical system

As part of the project, we helped our client undertake some performance baselines to determine read and write performance of the implementation. The EqualLogic PS proved to be very fast, achieving 42,000 IOPS for sequential write operations using MS SQLIO.
