We're building an stretch cluster with OES2 and NCS, having one HP EVA
SANs and 6 cluster nodes at each site.

For the SAN replication we need HP StorageWorks Continuous Access EVA

But HP told us we'll also need the following software to build the
whole solution:
- HP StorageWorks Cluster Extension EVA software
- HP ServiceGuard for Linux

Could anyone confirm that? reading the HP documentation, it seems that
some funcionalities of both products overlap with NCS.
