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?
