Business Drivers for Server Virtualization
▸ CAPEX savings is the #1 driver for Server Virtualization• 40% of users cite CAPEX savings as
their #1 driver▸ Easily quantifiable OPEX is next on
the list, followed by Flexibility and DR▸ Users on average have virtualized 35%
of server workloads▸ More than 75% of respondents plan to
virtualize at least 2/3 of their workloads within next few years
Server Virtualization will continue to be a technology driver over the next few years

Virtualization Reality: Memory Limitations Make Storage A Precious ESX Resource
ResourceUtilization
Before Consolidation
After 10x Consolidation
CPU 6% > 60%
Memory 40% > 400%
Network I/O < 5% > 5%
Disk I/O < 5 % > ? %
ESX techniques for handling memory over-commitment:
1. Page sharing2. Ballooning 3. Swapping
1. Random ESX I/O stresses disk performance2. Traditional storage with large caches not effective 3. VM performance gated by disk IOPs and storage capacity

3PAR Integration with VMware Adaptive Queue Depth Algorithm for Automated IO Queue Management
▸ New QoS feature in VMware vSphere 4 and ESX 3.5 U4• Developed by VMware in
collaboration with 3PAR• Dynamically adjusts the number
of queued I/O on a LUN• Helps recover gracefully from I/O
congestion at the port level
▸ 3PAR storage is qualified with VMware Adaptive Queue Depth
▸ Allows customers to consolidate more VMs per ESX server since I/O traffic levels are regulated dynamically
©2010 3PAR Inc. All rights reserved. | 3PAR Confidential 16
Greater Scalability and Agility: Hardware Assisted Locking (ATS)
▸ New feature in VMware vSphere 4.1
▸ Improved VM density and scalability
▸ Greater agility while performing common actions• Storage vMotion
• Powering on/off a VM
▸ 3PAR Unique advantage• Data comparison operation is 10x
faster
• Performed in 3PAR ASIC vs.
Array controller CPU
▸ Benefit seen in consolidated environment and Hosted Service Providers
©2010 3PAR Inc. All rights reserved. | 3PAR Confidential 17
Greater Agility for Enterprise and Cloud Datacenters: Fast Copy (XCOPY)
▸ New feature in VMware vSphere 4.1
▸ Greater agility while performing common actions• 2x better performance with VM
Cloning

Complexity of Traditional Storage
▸ With traditional storage, provisioning is complex, slow and labor-intensive• Requires careful and time-
intensive upfront planning• Results in brittle
configuration• Requires many more
administration resources
©2010 3PAR Inc. All rights reserved. | 3PAR Confidential 20
Simplified Storage and Server Provisioning
▸ 3PAR Rapid Provisioning• Seconds to provision
storage with no pre-planning
• Self-configuring and auto load-balanced storage volumes
• Labor-intensive and careful planning eliminated
▸ Benefits• Minutes to provision virtual
servers• Dramatic reduction in
storage administration
©2010 3PAR Inc. All rights reserved. | 3PAR Confidential 21
Clustered environments add additional complexity to storage provisioning
▸ VMware clusters create new storage management challenges
▸ 1 cluster of 5 hosts and 10 volumes, requires 50 provisioning actions on most traditional arrays!• At 10 min/action: More than 1
day!• Error-prone
▸ VMware clusters are dynamic resources subject to growth and frequent change
©2010 3PAR Inc. All rights reserved. | 3PAR Confidential 22
3PAR Autonomic Groups eliminates repetitive error-prone tasks
▸ 3PAR Autonomic Groups
• Simplifies and automates volume
provisioning in a single command
▸ Exports a group of volumes to a host
or cluster of hosts
• Automatically preserve same LUN ID
for each volume across hosts
▸ When a new host is added into the
host group:
• All volumes are autonomically
exported to the new host
▸ When a new volume is added into
the volume group:
• New volume is autonomically exported
to all hosts in the host group
