snydeq writes "InfoWorld's Paul Venezia takes VMware's purported 'cloud OS,' vSphere 4, for a test drive. The bottom line: 'VMware vSphere 4.0 touches on almost every aspect of managing a virtual infrastructure, from ESX host provisioning to virtual network management to backup and recovery of virtual machines. Time will tell whether these features are as solid as they need to be in this release, but their presence is a substantial step forward for virtual environments.' Among the features Venezia finds particularly worthwhile is vSphere's Fault Tolerance: 'In a nutshell, this allows you to run the same VM in tandem across two hardware nodes, but with only one instance actually visible to the network. You can think of it as OS-agnostic clustering. Should a hardware failure take out the primary instance, the secondary instance will assume normal operations instantly, without requiring a VMotion.'"

Guanine writes in with a follow-up to our discussion a few months back on the SheevaPlug: 1.2-GHz ARM-compliant processor, 512 MB DDR2, 512 MB flash, USB 2.0, gigabit ethernet, in a package the size of a wall wart, for $99. Saul Hansell's Bits Blog in the NY Times talks about a few applications for such a device, whose price point Hansell claims will drop to $40 before too long. "The first plausible use for the plug computer is to attach one of these gizmos to a USB hard drive. Voila, you've got a network server. Cloud Engines, a startup, has in fact built a $99 plug computer called Pogoplug, that will let you share the files on your hard drive, not only in your home but also anywhere on the Internet. ... [Marvell's CEO said] 'Eventually you won't see the plug. We want this device to be in your TV, your stereo system, your DVD player.'"
