Hi Folks,
Perhaps someone here might be able to point me at a reference or two on
alternatives and best practices for configuring storage for a server - using
a mix of SSDs and conventional drives.
I'm in the process of upgrading a small cluster of 4 machines - each
containing RAID arrays, with DRBD across clusters to support failover. Easy
enough with a uniform collection of HDDs. But I can't get my head around
how to add SSDs into the mix - what with the mismatch in access speeds and
all, it would seem like one needs a more complex configuration with a level
of caching between the faster and slower media.
Seems like someone would have written a book, or tutorial, or case study, or
conference presentation - but damned if I can find anything. Any pointers,
or guidance, would be much appreciated.
Thanks,
Miles Fidelman
