Nexenta recently launched NexentaVSA for View that is designed to handle the storage demands made by desktop workloads that are executing in a VMware View-based, server-based environment. The company points out that virtual desktops use storage differently than server-based workloads do, so they need to be configured differently.
NexentaVSA for VDI is a purpose built storage appliance that provides advanced features and functionality suited to handle the demands of a virtual desktop environment. NV4VDI improves desktop / storage performance by providing better IOPS, latency, and boot storm response. NV4VDI can scale to thousands of machines without changing design or incurring cost overruns, thereby lowering the overall cost of deploying and managing a desktop.
NexentaVSA for View provides comprehensive functionality, including in-line data deduplication and in-line compression, flexible back-up and restore, unlimited snapshots, metadata acceleration, and uniform IOPS at any scale.
Nexenta is one of several storage virtualization suppliers that are offering products designed to increase the overall performance and reliablity of virtual desktop environments. Other suppliers of products that address the same issues include companies such as NetApp, EMC, IBM, HP, Hitachi Data and a few others.
Why is this necessary? Well, there are many differences in how server-centric and desktop workloads use storage. Just connecting the host server to a virtualized storage environment may or may not perform well. Some of the differences follow:
Nexenta says that it has addressed all of these requirements and has make it possible for VDI environments to perform well and be managed by VMware's Horizon View management environment. While this is likey to make VMware View users happy, VMware is not the only VDI game in town. It is not clear at this moment if users of Citrix or Open Source desktop virtualization environments would see similar benefit from NexentaVSA.
Furthermore, encapsulating complete desktop environments and moving that image to servers is not the only form of desktop virtualization. Some approaches to virtual desktops are based on access or application virtualization rather than relying so heavily on virtual processing.
Nexenta is offering some interesting technology that might be of great help if your organization's virtual desktop program is based upon VMware. It would be worth examination if that is what your environment is using. If not, then the products being offered by others would be worth considering.
