Latest migrations show SSD is ready for some datacenters

jmke · 20th October 2009, 17:56

When we asked the IT pros in the Server Room to name the number one barrier to solid state disk (SSD) adoption in the enterprise, "price" was the near unanimous consensus. SSD storage is still significantly more expensive than rotating magnetic media, but with datacenters becoming ever more constrained by power and cooling considerations, the overall price picture for SSD vs. HDD keeps getting better. Sure, at the level of an individual drive, the cost/GB difference between SSD and HDD is still huge, but at the level of the overall datacenter, with floor space, power, and cooling factored in, the delta now looks a lot smaller.

Our production servers that host data at my company are all basically disk limited. They are all 100 nodes clusters each running 2 1tb 15k SAS drives using the SuperMicro twin servers. We just recently started testing these in smaller clusters using 4 160gb Intel SSDs in 2 raid0 arrays. Those 10 servers can keep up with the requests going to the 100 node clusters, but right now the capacity is whats holding us back from moving them into production. The slower write isnt really a problem for us because the data is only updated once a day 5 days a week, and clusters are pulled out of production while updated.

I'de be surprised if many companies would trade regular disks that have already proven their reliabilty for SSD that are relatively new.

I would never utter the words reliability and HDDs in the same sentence when it comes down to single disks

we've got another few disk failures last month

Yeah, some people I know just had a bunch of HDDs die out... scary how it is quiet for a few months, then suddenly three or four people you know have one or even two drives die (or slowly fail) on them.

Many of the hard drives were only 3 years old... I bet with typical usage an Intel SSD easily would outlast 3 years... better question is if it can last 5. SLC based SSD's should easily last beyond 5...
