|NexentaVSA for VDI|
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.
Basically stated, however, today’s challenges relating to storage and legacy VDI vendors are three-fold:
The transition to VDI is much more complex than the transition to server virtualization. This is where NexentaVSA for VDI can help.
How it Works
NexentaVSA for VDI’s software-only solution provides advanced features and functionality suited to handle the demands of a virtual desktop environment. By combining storage and computing, NV4VDI enables a complete ‘storage-in-a-box’ solution for both persistent and stateless desktops.
NexentaVSA for VDI leverages SSDs, which do not require you to keep your entire environment loaded in expensive and unsafe memory. SSDs provide benefits such as separating the read and write cache for the VDI workload and making the entire cache completely transparent to the end user. And for data security, NV4VDI, utilizing ZFS technology, guarantees end-to-end, air tight data integrity (competitors use unproven Linux or other file systems).
Initially, a virtual storage appliance is installed on the same hardware where the VDI virtual machines are installed. This dramatically improves storage performance for all VDI machines.
In addition, hardware-agnostic NV4VDI leverages your existing investments in external storage hardware (be they NetApp, EMC, Compellent, or others) for dedicated desktops.
Deployment for Your Specific Needs
Persistent (dedicated and Stateless/floating)
NexentaVSA for VDI is designed to be flexible—supporting both dedicated (persistent) and floating (stateless) desktops. The solution includes NexentaStor and HA Cluster already integrated into NV4VDI. Preset values for a tuned desktop environment initially are based on the Dedicated or Floating settings.
For floating desktops, NV4VDI integrates compute and storage. The virtual storage appliance is deployed on the same server as virtual machines for the desktop. Since NV4VDI is integrated with vCenter, customers can scale these multiple integrated (compute and storage) units in a highly available configuration.
Figure 1: Stateless (or Floating) Desktops
For persistent desktops, local virtual storage appliances (see Item #2 in Figure 2, below) continue to provide the necessary IOPS required by the desktops. The local VSA can be complemented with an external storage appliance powered by NexentaStor. Customers get 16TB of NexentaStor license when they purchase NexentaVSA for VDI. User data can be retained in a highly available environment using this configuration.

As in Figure 3, customers can continue to use their choice of enterprise storage appliances, such as EMC, NetApp, or Dell. By using NV4VDI, they can offload the IOPS from the external storage appliance to the virtual storage appliance on the compute node.

NexentaVSA for VDI is optimized for the desktop workload:
When purchasing NexentaVSA for VDI, the package contains:
Fixed Unit (Desktop) Cost: NexentaVSA for VDI lowers the overall, long-term cost of deploying a desktop by providing a clear and fixed cost structure for scaling out as growth requirements are addressed, thereby avoiding the exponential (and usually unknown) costs of legacy solutions.
The price you pay for each desktop does not increase with expansion. Unlike legacy storage solutions, prices remain fixed as growth continues.
