Realize the Power and Flexibility of Virtualization

Is I/O limiting the power of your virtual machines? While VMs increase server utilization, they can also create bottlenecks at network and storage connections. One solution is to deploy more I/O to each server. VMware users typically deploy seven or more I/O connections per server, according to a recent survey. But this adds cost, creates cabling disarray, and limits your ability to deploy compact, 1U high servers.

Xsigo offers a better answer: Virtual I/O. Now you can add the connectivity you need to ensure performance and uptime, without adding excess cards and cables. And virtual I/O gives your VMs new mobility that’s not possible with conventional I/O.

Xsigo virtual I/O eliminates the NICs and HBAs in your servers. Instead, you deploy virtual NICs and virtual HBAs on the fly, as they’re needed. Network and storage traffic are consolidated to a single high-speed interconnect (or two for redundancy). For virtualization users, this delivers five benefits:

1. Provides dedicated I/O resources for all VMs.

• VMs deliver the same performance they would with a dedicated physical link.
• Supplies the performance and isolation of multiple connections, without all the cables.

2. Improves Quality of Service.

• Guaranteed I/O bandwidth ensures isolation, to protect bandwidth for critical applications.
• Enforced in hardware, Xsigo QoS demands no server resources.

3. Delivers full flexibility to migrate virtual machines.

• Suspend a VM on one device, then resume on any other, free from the restrictions and security implications of VMotion.
