How Virtual I/O Helps You Do Three Times More

with VMware vSphere and Intel Nehalem

VMworld 2009

• Data center in a 36U rack

• 960 virtual machines

• 160 cores

VMware ran all demos from one rack:

At VMworld 2008, it took 14 racks.

3 Ways Virtual I/O Helps

• More Bandwidth

• More Scalability

• Enables the Cloud

How Has Server I/O Changed?

What is Driving the Need?

What is vSphere?

VMware ESX 4.0New storage features

New network management features

Built for bigger jobs.

I/O Tuning• More efficient use of I/O resources

Fault Tolerance• Zero downtime and zero data loss availability • Instantaneous, stateful failover between the two

virtual machines

1TB Host Memory • Supports systems with up to 1TB of RAM

Enables more VMs per server

What’s new in vSphere?

Many new features, but for I/O…

What’s new in Nehalem?

3X more I/O capacity

How does virtual I/O help vSphere and Nehalem?

1) Scalable Connectivity

• Scalable I/O– vSphere requires NICs for Fault Tolerance logging and vMotion– Xsigo enables the needed I/O– Can move FT vMachines to any device

– Including blades and 1U servers– Reduces costs, cables, switching and dedicated hardware

vSphere Requirements

1) Scalable Connectivity

• Hardwired connections difficult to add / change

• Difficult to accommodate new requirements

Without Xsigo

With Xsigo • On-demand connectivity for:

• Vmotion• FT network• Management

• Meet future requirements without re-cabling

To get the most from vSphere, you need more I/O

• vSphere + Nehalem offer 3X more I/O capacity• Both eliminate limitations of previous gen products

• I/O becomes a limiting factor

Completes the cloud computing ecosystem

3) Enables Cloud Computing
