Links 7/22/2008: NetApp and Flash

Flash Forward – Jay Kidd, CTO of NetApp blogs that “NetApp is in the process of certifying enterprise-grade SSDs that you can use in our existing storage shelves.” No dates or pricing announced yet, of course, but he does make an excellent point about SSDs in storage arrays: “For the next few years, you won’t be using a lot of flash capacity in your systems, not just because of the costs. At 10x or more the IOP rate of hard disks, it only takes a small number of SSDs in disk slots to saturate the performance of the array controller. It’s like trying to fly a model airplane in your living room – you’ll run into a system performance wall long before you hit capacity limits. This is another reason that flash as cache is economically efficient – it puts the necessarily small amount of very fast storage at a point in the architecture where you can best exploit the performance.” Not unlike how Sun suggests using SSDs with ZFS.
