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
