ACCELERATE VDI PERFORMANCE WITH CITRIX XENDESKTOP AND PERNIXDATA FVP SOFTWARE
PernixData FVP software accelerates reads and
writes to storage by virtualizing server flash and
RAM, resulting in 10x faster VDI (even under
heavy load).
• 90% reduction in XenDesktop latency
• 62x more IOPS with same storage infrastructure
• Scale XenDesktop deployments without
problems
• Lower storage costs by 99%
SOLUTION OVERVIEW:
BENEFITS OF THE COMBINED SOLUTION:
Citrix XenDesktop mobilizes and secures Windows desktops so users can
access them from any device. This reduces desktop costs, while maximizing
control of content.
However, Citrix XenDesktop is very sensitive to latency. The slightest delay (or
variations in delay) can cause poor and/or inconsistent desktop performance.
This makes storage bottlenecks a big threat to the success of XenDesktop
deployments.
PernixData FVP™ software eliminates storage bottlenecks, making it a perfect
complement to Citrix XenDesktop. By moving storage intelligence into hosts
where the XenDesktop VMs reside, FVP lowers VDI latency by 10x–even under
peak loads. In addition, FVP provides a cost-effective way of scaling out storage
performance as your VDI deployment grows.
How it Works
FVP software is seamlessly deployed inside the hypervisor running XenDesktop
VMs (e.g. VMware vSphere). No changes are required to existing hosts, storage,
or VDI components (e.g. XenDesktop Controller, StoreFront, Director, EdgeSight,
Studio or receivers).
Once installed, FVP software virtualizes high-speed server resources. This clustered
pool of server flash and RAM acts as a low latency data tier. When XenDesktop VMs
read and write data, the requests are served by this tier, significantly speeding up I/O.

Key Benefits
High-Performance VDI
PernixData FVP software eliminates storage I/O bottlenecks by
serving reads and writes locally on the host. Typically, this results
in a better end user experience as VDI latency is reduced by up
to 90%.
Reliable Performance, Unaffected by I/O Storms
Various activities, like boot, login, logout, shutdown, AV scans and
update storms, generate substantial amount of I/O activity that
stress backend storage. FVP protects XenDesktop users from
slowdowns during these activities by storing this information in
flash/RAM across several hosts, which minimizes activity in the
array itself. Writes can be from the hosts to the storage array in a
predictable and consistent fashion, preventing the storage device
from being overloaded.
Deploy more desktops. With FVP software, storage performance
can easily grow with your virtual infrastructure simply by adding
more flash/RAM to an FVP cluster. This means you can get more
out of your current storage infrastructure and increase the VM
density on your hosts.
Extend the life of your storage device. With FVP software, a
significant amount of IOPS are offloaded from the storage array
to local hosts, extending the usable life of your storage device by
months or years.
Seamless deployment and management. FVP is a 100% software
solution deployed in less than 20 minutes inside the hypervisor.
It is managed natively by vSphere Web Client making it easy for
virtualization administrators to deploy and use.
Use your existing storage device. With FVP software, storage
performance (IOPS and throughput) comes from the low-latency
data tier. This means you can use your existing storage array for your
VDI deployment, instead of having to purchase a new storage array.
Lower storage performance costs by 99%. FVP decouples storage
performance from capacity, enabling cost effective scale-out. This
lets you avoid/delay a storage upgrade, or spend up to 99% less
(cost per IOPS) compared to new storage hardware.
Real World Example: Regional Bank
A regional bank was having performance issues as they grew their
Citrix XenDesktop deployment. They looked at upgrading their
storage array, but it would cost over $100,000 and not guarantee
an improvement in VDI performance. Instead, the bank invested
in PernixData FVP software. For 1/6th the cost, they got 100K IOPS
per host and 1K IOPS per desktop (FVP increased their VM density
by 2.5x, allowing the bank to deploy desktop VMs with a 100:1
consolidation ratio). This dropped VDI latency from 3 ms to less
than 0.4 ms, enabling the company to grow their VDI deployment
to meet end user demand.

Summary
To deliver the performance end users expect from their virtual
desktops, Citrix XenDesktop needs responsive storage I/O. This
can be difficult to achieve in a cost effective manner when storage
performance is intrinsically tied to storage capacity.
With PernixData FVP software and server flash/RAM, companies
get the best possible storage performance at the lowest cost,
ensuring that both end-users and IT departments are equally satisfied.
This makes the PernixData FVP platform a core infrastructure
component to any Citrix XenDesktop deployment.
