Agenda

▸ Server Virtualization Business Drivers & Storage Challenges

▸ Why 3PAR for Virtual Server Environments


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 Wide Striping enables higher VM Density

▸ 3PAR Wide Striping• Spreads volumes across all

disks• Delivers predictable

performance even at full capacities

• Allows a VMDK to be striped across all disks without capacity wastage

▸ Benefits for VMware• Higher and more predictable

service levels in VMware environments

• More VMware ESX servers to be consolidated per array

• Double #VMs per physical server

3PAR Gen3 ASIC is key for superior mixed workload support

‣ High speed, low latency interconnect between the controller nodes.

‣ Responsible for moving all data. Leaves CPUs to do what they do best - compute. Mixed workload built in.

‣ Mirrors writes in the HW

‣ RAID Calculations in the HW

‣ Zero Detect -Thin built-in to the HW

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


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


Greater Agility for Enterprise and Cloud Datacenters: Fast Copy (XCOPY)


▸ Greater agility while performing common actions• 2x better performance with VM

Cloning

▸ 3PAR Unique advantage• Only written data will be

cloned with EZT VMDKs

▸ Benefit seen in almost all VMware vSphere deployments

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


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


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


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

Autonomic Storage Tiering

▸ 3PAR Adaptive Optimization optimizes storage cost• Sub-volume optimization

software allows striping of data across storage tiers to lower cost

• VMware environments can take advantage of this capability with no additional configuration or tuning

• Cost optimization occurs autonomically via defined policies in the storage array
