Nytro WarpDrive Flash acceleration cards

LSI

LSI has worked with VMware to deliver what it says is breakthrough virtual desktop density for VMware Horizon View deployments. Collaborative testing with VMware Horizon View using a single LSI Nytro WarpDrive application acceleration card achieved concurrent support for 200 active virtual desktop infrastructure (VDI) workloads on a two-node cluster with no storage latency.

VDI environments generate I/O-intensive workloads that cannot always be adequately addressed by traditional hard disk drives. Typical VDI workloads generate small, random write-intensive bursts of I/O during peak periods, forcing IT organisations to over-provision expensive storage resources to meet that peak demand. The Nytro WarpDrive card helps to eliminate infrastructure guesswork and improve storage utilisation by providing a flash-based solution with both predictable and reduced application response times.

To demonstrate the benefits of deploying the Nytro WarpDrive card in a VDI implementation, LSI and VMware emulated demanding, real-world end user workloads using Login VSI version 4.02 and View Planner 3 to drive 200 active desktops. The LSI Nytro WarpDrive card comfortably supported the 200 active desktop workloads, achieving a VSImax rating of 280 before exhausting CPU resources. The demonstration also showed that at 150 desktops per ESXi node, eight hosts can easily scale to 1,000 concurrent desktops at a fraction of the cost compared to traditional storage area network deployments with similar performance characteristics.
