Realise the Power and Flexibility of Virtualisation
Is I/O limiting the power of your virtual machines? While VMs increase server utilisation, 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 or blades.
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 virtualisation users, this delivers five benefits:
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.
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.
Delivers full flexibility to migrate virtual machines
- Realise the Power and Flexibility of Virtualisation. Suspend a VM on one device, then resume on any other, free from the restrictions and security implications of VMotion.
Enables I/O resource mobility
- Move connectivity from any server to any other server.
- If a server fails, the entire I/O identity can immediately be replicated on another device.
Provides the ability to use smaller servers
- Xsigo reduces physical I/O resources by 70%, so you can more often use space-saving 1U high servers.
Summary
Xsigo virtual I/O delivers predictable performance, better VM mobility, and more complete isolation. Don't let physical I/O limit the power of your VMs. Get virtual I/O, the server connectivity that was designed for virtual machines....Xsigo Director Product Overview
