HOW VDI DEPLOYMENTS BENEFIT FROM VIRTUAL I/O
	Accelerates response time with 1/3 the latency of 1G Ethernet Eliminates I/O bottlenecks with up to 80Gb/server Ensures user experience with QoS controls Enables isolated networks to any server

The VDI Challenge

VDI (Virtual Desktop Infrastructure) places significant demands on servers and data center infrastructure. Your desktop users expect the performance of a local machine, with fast boot times and responsive applications. You need a VDI delivery model that is reliable, efficient, and straightforward to deploy. And of course, these requirements must be met at a cost that is inevitably compared with the desktop machines being replaced. Xsigo virtual I/O helps you meet these objectives with the industry's simplest, highest-performance server I/O.

40Gb Performance for a Superior User Experience

A great VDI user experience demands fast response time under all load conditions. Xsigo offers benefits that help you deliver the best possible performance:

• Up to 80Gb bandwidth to each server eliminates I/O bottlenecks
• 1/3 the latency of 1G Ethernet to accelerate network, storage, and server-to-server communications

Accelerate thin app servers and speed users through the login process by minimizing the "boot storm" impact when clients log on simultaneously. Get performance that users will appreciate.

Network Isolation for Multiple Workgroups

When specific workgroups require physically isolated networks, complexity may grow. You could host those groups on separate servers, or provide multiple physical connections to each server. But those options add cost and complexity. Only Xsigo lets you configure isolated environments, within a single group of servers, free of hardware limitations. Establish multiple connections to each server, in software, without even entering the data center.

70% Less Complexity Simplifies Deployments

Xsigo's simple architecture minimizes your space and power requirements and accelerates your VDI rollout.

• Reduced server size: With Xsigo you need just two I/O links per server, giving you the flexibility to choose the smallest, most efficient server that meets your needs - even 1U servers or blades. PCI slot count is no longer a concern since you can configure all needed I/O with just one or two host adapter cards - or possibly even with no cards at all with Xsigo's 10G Ethernet fabric option. All of these options flexibly provide redundant, isolated Ethernet and Fibre Channel connections from your servers to the networks and storage.
  
  
• Fewer switch ports & less cabling: Xsigo reduces switch port and cabling requirements by 70% saving space and cost. Furthermore, as you grow you can add servers with just two I/O cables each. Minimal space requirements plus the simplest possible cabling make expansion a breeze.

Open Architecture Lowers Capital Costs

CAPEX savings with Xsigo may total $10,000 per server or more. In addition to eliminating 70% of the cards, cables, and switch ports, Xsigo also features an open architecture that lets you use the servers, networking and storage of your choice. So you can re-use the gear you have and select whatever components meet your needs.

Remote Management

Xsigo lets you manage I/O from anywhere. Because there is no need to move cables or to enter the data center, I/O can be managed from across the campus or across the globe. This can save steps or even trips.
