Does anyone have experience of using the Lefthand P4000 kit to implement a "stretched" ESX farm across 2 active-active data centres. How does this compare with the other players (EMC, NetApp, Compellent etc.) Is the lack of sub-LUN storage tiering an issue? We are considering doing this over a dark(ish) fibre connection between 2 sites, using VMWare high availability in order to implement automatic DR/BCP if we lose a data centre. The sites are around 10 miles apart. The Lefthand solution looks nice, because the failover is automatic, and because they support using a third site for a quorum server, to resolve split-brain issues. I'd be interested to hear your experiences.
