We're at a point where server virtualisation is really becoming pervasive. Very few technologies have the kind of impact that server virtualisation is having on the market today, and there is no end in sight.
Everybody is adopting server virtualisation regardless of geography or company size, so it's a very important issue. And server virtualisation actually drives people to take storage that was otherwise internal or direct attached and network it. It doesn't make much sense to keep storage inside servers with a lot of virtual servers on them. It's like owning a TV but only watching DVDs and foregoing cable, you just lose a lot of the value.
Server virtualisation allows users to put every server on the San [storage area network]. For example, you can move images around to any server platform, you can replicate and load balance between servers, do upgrades and so on. We're hearing more users talk about server virtualisation with Nas [network attached storage], and if you're a Nas shop, it makes tremendous sense. We see the adoption of server virtualisation expanding in Nas environments.
