Virtual I/O Overview

Less Cost, More Flexibility


Xsigo virtual I/O dramatically reduces the capital and operational costs of server connectivity. By dynamically connecting any server to any network -- both Ethernet and Fibre Channel -- Xsigo virtual I/O enables a simpler, lower cost infrastructure that eliminates the limitations of cards, cables, and switch ports.

With Xsigo virtual I/O, you can move, add, or change connectivity on demand. Configure up to 64 separate connections per server through a single cable, and manage I/O in software, not hardware. Re-purpose servers or add I/O connections in seconds, not hours. Learn more about the cost savings here.

Enable a Dynamic Infrastructure

You need to get the most from your resources, and Xsigo’s dynamic I/O helps you do just that. Re-purpose assets quickly using Xsigo’s intuitive user interface and rich management feature set. Xsigo makes it easy to deploy assets when and where they are needed.
