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.

How does virtual I/O help vSphere and Nehalem?
![Page 19: How Virtual I/O Helps you do 3X More with VMware vSphere and Nehalem](https://reader033.vdocuments.us/reader033/viewer/2022061218/54820e6cb47959fb0c8b46b3/html5/thumbnails/19.jpg)
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
![Page 20: How Virtual I/O Helps you do 3X More with VMware vSphere and Nehalem](https://reader033.vdocuments.us/reader033/viewer/2022061218/54820e6cb47959fb0c8b46b3/html5/thumbnails/20.jpg)
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
