I have to say I *always* advise against separating indices and bootstraps off 
to dedicated pools.

It makes for a bunch of configuration hassles, and it also increases media 
contention when there is no logical reason to have separation. You don't really 
recover indices any faster by having them on their own devices; they're still 
going to be multiplexed to the same degree as backups to any other device, and 
by having them written to dedicated pools, you increase drive contention.
