Virtualization Without Compromise: Virsto for XenDesktop

May 2012Eric Burgener, VP Product Marketing

Gregg Holzrichter, VP Marketing

No Compromise Virtualization High performance AND space efficient - no longer either / or choice

Finally Save Costs with VDI Support over 2x the desktops per host & Increase storage utilization by up to 90%

Persistent Desktops that are cheaper and higher performance than physical

Effortless Provisioning & Patching at Scale Virsto snapshots & clones support XenDesktop 5.5 native workflows

Transparent management of VDI

Virsto for XenDesktop 5.5

Changing the economics of storage for virtualized desktops

2

Seamless Integration with XenDesktop

Virsto Rapid Deployment Utility supports XenDesktop 5.5 running on VMware ESX/ESXi 4.1 or ESXi 5.0

Transparently leverages Virsto for storage provisioning while using standard desktop creation workflows Effectively replaces PVS, MCS

Supports the standard deployment, re-deployment and refresh workflows

Virsto XenDesktop Connector hands Virsto-provisioned desktops over to Desktop Studio

vClone (4KBs)

The vSnap is a pointer to an immutable moment in time… 4Kb, no performance

impact upon creation

To make the vSnap usable for I/O, we create a vClone from it. Initially also is

just a pointer to the original data

Sector 0Sector n-1

A vClone is a read/write copy of the Golden Master. Also created with no

performance impact and at 4Kb

The relationship between the virtual blocks and their physical location is

maintained in a mapVM
