As virtualization slowly takes over almost everything in information technology, certain things need to change. One of those things is the way storage operates. Traditional enterprise storage was built for a time when physical machines were king, and there was only one operating system, and often only one workload, per physical server. Virtualization changes that, putting multiple workloads and multiple OS images on a single host, often causing predictive algorithms for caching to fail because the I/O from a particular server looks almost completely random (sometimes referred to as the “I/O blender”). In fact, the I/O isn’t random, it’s just the result of multiple VMs each doing their own thing. Most monolithic storage vendors have adapted their arrays to better understand this new type of I/O, at least in part. However, there is a whole new class of storage company that is looking to start over, upending the storage market by pairing commodity hardware with deeper understandings of virtual environments and new management models.
