Are SSDs reliable enough? The importance of extensive testing under adverse conditions.

Recently, interesting research (see here) from researchers at Ohio State was presented at USENIX.

To summarize, they tested 15 SSDs, several of them “Enterprise” grade, and subjected them to various power fault conditions.

Are some flash storage vendors optimizing too heavily for short-lived NAND flash?

I really resisted using the “flash in the pan” phrase in the title… first, because the term is overused and second, because I don’t believe solid state is of limited value. On the contrary.

However, I am noticing an interesting trend among some newcomers in the array business, desperate to find a flash niche to compete in:

Writing their storage OS around very specific NAND flash technologies. Almost as bad as writing an entire storage OS to support a single hypervisor technology, but that’s a story for another day.

NetApp posts world-record SPEC SFS2008 NFS benchmark result

Just as NetApp dominated the older version of the SPEC SFS97_R1 NFS benchmark back in May of 2006 (and was unsurpassed in that benchmark with 1 million SFS operations per second), the time has come to once again dominate the current version, SPEC SFS2008 NFS.

Recently we have been focusing on benchmarking realistic configurations that people might actually put in their datacenters, instead of lab queens with unusable configs focused on achieving the highest result regardless of cost.
