Benefits of Server Caching for VDI

Lower cost of IOPS

Improved performance: IOPS and latency

Server-based manageability

Smaller blocks for scalability

Predictable performance at scale

Less power consumption and floor space

Traditional Architecture

Virtual Desktops Platform + OS and Hypervisor

Server Storage

Controller Storage Media

• Read and write operations serviced by the storage array• For IOPS-intensive workloads, backlogs and serialization occur at the access fabric, storage controller, and

storage media• Best read and write performance would be read from and write commit on the storage controller write cache• Queue depths on the controller serialize IOPS

Write latency = ~ 600 microseconds to 15 milliseconds (ms)

Read latency = ~ 600 microseconds to 10 ms

Write latency = ~ 600 microseconds to 15 milliseconds (ms)

Read latency = ~ 600 microseconds to 10 ms

• Reads and writes serviced by Cisco UCS® storage accelerator (PCIe flash memory)

• 10 times more IOPS compared to 20 times more for SSDs behind a RAID controller

• Consistent performance of random read-write operations

• Queue depth does not matter

Cisco UCS storage accelerator-based solution can reduce average read latency by 5 times compared to enterprise shared storage

Cisco UCS Architecture with Citrix

B200 M3 Blade ServerVDI clones x 140+ per blade (streamed from Citrix PVS vDisk)

• Cisco UCS® server with 8 GB of RAM, and 2 CPUs

• OS caches vDisk file data at the block level• 64-bit OS provides better caching performance:

typically up to 1000 streams per server

Economics of IOPS

* Includes industry-standard enterprise storage to support up to 2000 desktops with 1-year support (US$286,000), 4 ports of Cisco Nexus® 5000 Series Switches, and 4 storage port licenses for Cisco UCS fabric interconnect, all at ASP

** Includes Cisco UCS and Fusion-io 785-GB cards at ASP

Storage Costs for 2000 Virtual DesktopsFor 2000-desktop solution, Cisco UCS® and Fusion-io flash memory solution can reduce storage costs by 50% compared to standard enterprise shared storage

A single Cisco UCS Fusion-io 785-GB card can provide up to 500,000 writes (512 KB): about 10 times more write IOPS than typical shared storage for 2000 desktops

A single Cisco UCS Fusion-io 785-GB card can provide up to 100,000 reads (512 KB): about 3 times more write IOPS than typical shared storage for 2000 desktops

Power Consumption and Floor Space

* Assumes that a typical 15,000-rpm SAS drive on Industry-standard enterprise storage consumes 8W, and assumes 20% additional overhead for controller, shelves, and management nodes ** Cisco UCS and Fusion-io 785-GB card typically consumes 20W, and on average 130 virtual desktops are supported on Cisco UCS B200 M3 Blade Server

• Cisco UCS® storage accelerator is 16 times more energy efficient per virtual desktop compared to typical enterprise storage

• Cisco UCS storage accelerator consumes no incremental floor space for the solution
