VDI review: Kaviza VDI-in-a-box

Kaviza VDI-in-a-box comes closer than eitherPano LogicorNComputingto being a one-size-fits-alldesktop virtualizationsolution. It is also straightforward to deploy. Available as a preconfigured virtual machine, Kaviza installs into an existingVMware ESX/ESXiorCitrix XenServerinfrastructure, and it provides connection brokering, load balancing, user access control, and guest VM management in a single browser-based console. It supports both Microsoft RDP and Citrix HDX remote access protocols, as well as Kaviza's own Java-based client, so client access is nearly universal.

UnlikePano Express,Kaviza不进来一个大盒子的怪胎y goodies to install and configure. For deployment, IT will simply download the Kaviza virtual machine from Kaviza's website and import it into their existing VMware or XenServer host (support for Hyper-V is forthcoming). At first glance, the requirement to have a hypervisor already in place would seem like a deal breaker when compared to other solutions that include the server hardware (Pano Express) or require nothing but a good desktop PC (NComputing). But if you crunch the numbers, a typical virtual desktop using Kaviza can be had for about $425 per concurrent user (based on 50 users) -- including server hardware, VMware hypervisor, the Kaviza software, and Windows client licensing.

One reason the cost is almost half the price of a standard desktop PC is that Kaviza runs just fine on a "commodity" server, by which I mean a server with about eight CPU cores, 32GB of RAM, and some form of fault-tolerant local storage. There's no need for an expensive high-speed SAN or redundant servers. Kaviza claims this platform can handle at least 30 concurrent users. I didn't try to replicate that in my lab, but I had no trouble with 10 simultaneous users running 32-bit versions of Windows XP Pro and Windows 7 Pro on similar hardware.
