Virtual Desktop has become a high priority for many users and yet has not been widely deployed due to challenges with networked storage. VDI is one of the top applications that customers use the Hyper ISE because we provide the ideal balance of price/performance/capacity as well as rock-solid reliability.

Independent research shows that 98.85% of all users are planning; evaluating, implementing or have already deployed VDI. This is a clear mandate that VDI offers clear-cut value to companies and organizations.

There are four main reasons for deploying VDI including ease of management; reduce the cost of desktop upgrades, consolidation and to improve security.

However, VDI implementations do face some major challenges and many are directly related to storage. Some users experience boot up times of several minutes, which impacts their overall dissatisfaction with VDI. The cost of networked storage is high compared to internal disk drives and often more capacity is needed per users in order to provide performance. Again, performance often is visibly slower because of networked storage performance and this is unacceptable to most users.

One of the main values that VDI provides is consolidation. However, this can create a debiliating bottleneck with your network storage. The I/O contention becomes too great and applications can become painfully slow and in some cases cease to work at all.It is essential that you are aware of the “games” some vendors will play to convince you they can meet your performance requirements.
Incorrectly assume the number persistent users
Underestimate IOPS per user
Capacity per user is configured at the low end
Unable to handle a large number of simultaneous boot-ups
Inability to self-optimize performance

Performance is critical to the success of your VDI implementation. It impacts everything – user experience, application performance and the overall cost of the environment.
It is important to have enough IOPS per user otherwise you will either have slow performance or pay too high a price for performance.
Hyper ISE was designed and architected to provide a low cost per IOPS and per GB. Hyper ISE can support thousands of VDI users in a single 3U, 14.4 TB storage system.

Hyper ISE performance provides a high number of IOPS enabling a high number of virtual desktops sharing a 3U storage supporting 14.4 TB of capacity. Performance varies based on the type of workload and the environment but if you calculate 20 IOPS per desktop, even at 60,000 IOPS that is 3,000 virtual desktops. At 100,000 IOPS it results in 10,000 virtual desktops, etc. Additionally, XIO customers can aggregate multiple Hyper ISE systems using our software, X-Volume provides near linear scalability. Therefore, the performance of Hyper ISE continues to increase meeting the needs of any high performance environment.

The Hyper ISE storage system was designed for performance. And here is something that you must take into account – most vendors provide you performance information based on “best-case-scenario”. However, their performance degrades as they reach high levels of capacity utilization; during RAID rebuilds, performing data movement, mirroring or when they have any drive issues. However Hyper ISE has been architected to minimize any performance degradation that is felt by the users or applications during any or all of these conditions occurring. Hyper ISE is fast forever.
