Hello, I have an older AMD Opteron 240 with 8 GByte Memory (4 x 2 GByte modules) which can have up to 16 GByte of memory. Now I like to install 42 Web- and Mailservers onto it, since I do now want to use a 42HE/19" Rack currently (too expensive @hostingprovider). Some of the Servers have large Debian repositories and CD-Images to download. (I use 30 SCSI-Drives of 300 GByte divided in 6 Raid5 ensembles) Now my question is, what resources must I calculate? Should/Must I update the two CPU''s and increase the memory?

It can only be said that Xen does not use much of ressources on it''s own, but an important factor when using virtual disks and nics might be that they produce load on the dom0 cpu, also.
