I'm using NexentaStor (Solaris, ZFS) to export iSCSI-LUNs and I was thinking about a SSD based LUN for the indexes. As I'm using multiple servers this LUN will use OCFS2.
Given that the SAN always has the network latency behind it, might you be better to look at putting the SSDs in the frontend machines? Obviously this then needs some way to make users "sticky" to one machine (or some few machines) where the indexes are stored?
Storing the indexes on several machines? In this case I have to synchronize them.
maybe i am missing something. if a client has to fetch the index, the server has to read the index from disk and pass it back. the network latency is unavoidable, but i don't see why putting the fastest possible SSD on the server isn't a win. possibly i am misunderstanding something?
