Boot from SAN, why? what is the recommendations?
What is the recommendation for doing boot from SAN?
I have /,/var,swap partitions, with of them is recommended to put on the SAN for sure?
Generally, what are the advantages and the disadvantages for using boot from SAN?
As I see it, the big advantage to create /,/var on the SAN because it is good for DRP/DRO for copy those's luns on a backup site, which have the same server(hardware).
I checked also the performance, and it seems that the i/o performance was improved after I moved to boot from SAN.
NOTE: my SAN is McData4700 and AMS-500(HDS storage with 2GB cach)

Some organizations like it because it provides complete separation between a host and the data. So if the host needs to be replaced, another can be substituted that boots identically.

Depends on who you're talking to. I don't think most people or organizations are set up to do SAN booting, but you can do it if you have the correct tools.

Greater complexity, greater dependence on identical hardware, provides separation between hardware and data.

Yes.

Probably. But the contents of your OS disk aren't normally a performance bottleneck in most workloads (and if they are, you're probably storing the data incorrectly).
