In a follow up to this question:
I'm evaluating my next hardware configuration and I'm looking for advice on what to use for a HBA.
Specifically the link mentions the PERC H710/LSI card, and having to use a RAID0 for each drive, vs JBOD.
The PERC 710 doesn't support JBOD, but does have a write cache. The 310 does JBOD, but doesn't have a write cache.
Seems like a write cache is a good thing. Trying to answer:
Is the 710 RAID0 a real bummer (vs JBOD)?
Is having a write cache a big deal for typical Hadoop loads?
So much so that I should look at other HBA cards that don't have these problems?
