Right now their students use PC's, and each student has their own USB harddisk (provided by the school) where they keep their data. The 700+ PC's they use right now at the school are a mess. Malware, trojans, viruses ... With VDI you could (at least in theory) give each of those students "their own" virtual Windows XP instance (or whatever other OS is desired; e.g. many of their CS students use Linux too). So in other words: with VDI a Sun Ray DTU kind of "turns into" a full PC. The customer could then dump those USB disks the students are constantly moving around with (and thus spread infections between the PC's) because with hotdesking you don't need USB disks anymore ... your data follows you wherever you go. Administration would get easier too: Right now when one of the 700+ PC's is infected one of the admins needs to trigger a reinstallation. They use Novell ZenWorks right now, but it's not really ideal. They spend a lot of time and bandwidth sending installation packages over their network, just because they constantly need to reinstall one of their PC's ... With Sun Ray, VMware and VDI this issue does not exist anymore. You simply clone the "golden master image" (= one good Windows XP VM which is running as it should and which is configured and customized the way their administrators want it) again, replace any potentially crippled VM's, and voila, you're done. So that's how VMware fits into the picture. :) Regards, DJM. > > From: [email protected] > [mailto:[email protected]] On Behalf Of scorp123 > Sent: Wednesday, 11 March 2009 3:05 AM > To: SunRay-Users mailing list > Subject: [SunRay-Users] Question: Server hardware suggestion for 1200 Sun > Ray thin clients? > > > > Hi all, > > a customer of mine (a local college here in Switzerland) want to replace > their 700+ existing PC's with 1200 Sun Ray DTU's.
