Xiotech ISE was designed with the 2.5″ drives fully in mind. Today, one can have 40 enterprise 2.5″ drives in a 3U container, with full managed reliability and self-healing. The benefits to performance-starved applications are many – but perhaps the best benefit of all is the lack of having to, as a human, deal with herding and managing all these small creatures. This is why no enterprise array vendor except Xiotech has architected the 2.5″ drives into a fully-baked architecture. For others, like the pod people, they are just impossible to control, especially in arbitrated loops.
