It’s no surprise that traditional storage performance falls off a cliff in heavily virtualized server environments. Originally designed to interface with a limited number of hosts, legacy dual controller storage architectures simply cannot meet the I/O workload demands of multiple virtual machine (VMs) application instances. To avoid storage I/O bottlenecks, Hyper-V virtualized infrastructure planners need to consider newer storage paradigms that can dynamically optimize the storage I/O path between virtualized applications and the storage resources assigned to them.
