HP MSA500 G2 support for multi-path IO (MPIO) on x64
Am building two SQL 2005 clusters on Windows 2003 Enterprise R2 up in Birmingham, nice bit of kit - four DL380's and two MSA500 G2 SAN's - they come as a cluster package.
Like most people, I'm using x64 versions for Windows 2003 and SQL Server 2005.
Ok, now the crunch; if you buy the 4 port adapter on the back of the MSA500 R2 and try and have controller redundancy (multi-path) between each node in the cluster and the SAN then there is no driver for x64 multi-path, there is for the MSA1000 but I'm not inclined to use another product's drivers even if it is the big brother to the MSA500.
I've been on to HP and nobody will commit to a date when the drivers will be available.
What a pain.
Oh, its buried in the documentation as well; I diagnosed the problem because you see two disks in disk administrator for each logical partition - very strange but understandable.
