Last September, Microsoft released some information about what customers could expect to see in Windows 8, and at the very end of February the Windows 8 beta became available. There’s been some interesting activity on the blogosphere about it (see a good blog from Jason Perlow here).
There are a couple of interesting storage enhancements in Hyper-V R3, including VHDX, ODX, built-in deduplication, support for SMB 2.2, and the introduction of ReSF (Resilient File System). In Hyper-V R2, VHDs can be up to 2TB in size, but in Hyper-V R3 with VHDX that has increased to 64TB. While not imposing any limitations themselves, because Virsto vDisks effectively impersonate native VHDs, their size is limited by the native VHD capacity constraints. Virsto welcomes the introduction of VHDX, as this also increases the maximum virtual disk size we support in Hyper-V environments. When Windows 8 ships, Virsto will be supporting vDisks up to 64TB in size. The expanded storage capacity nicely complements increases in CPU and memory on a per VM basis that will allow Hyper-V to host larger, higher performance applications. With Virsto’s unique ability to provide high performance, thin-provisioned, fully cluster-aware storage, Virsto customers will be able to even better support larger, more mission-critical applications with smaller, more cost-effective storage footprints.
