Xen users - Dec 2013 - Newbie: Xenserver Hardware/setup configuration recommendations

I''m a newbie to Xen, and have been given the go-ahead to spec out a 
medium-ish sized system to run VMs on for development/testing.

We are primarily an HP server shop. I''m looking for detailed
information
about hardware configuration recommendations - memory, disk, NIC ports, 
processors, etc.

Could someone point me to some good info?


Thanks.

This list is mostly to do with the upstream Xen.org version of Xen, and
the supported hardware will depend on the underlying distro and kernel
which you choose.

XenServer is in effect its own distro so for XenServer specific advice
you will probably find more folks on the www.xenserver.org lists or the
XenServer forums at
http://forums.citrix.com/category.jspa?categoryID=101 or your Citrix
Support channel folks. I''m fairly certain that XenServer also publish a
Hardware Compatibility List, I''d be amazed if there weren''t a
bunch of
HP systems on it.

If you want to deploy upstream Xen on a regular distro then IMHO the
best advice is to pick a Linux (or BSD) distro which you are familiar
with and check if there is any Xen advice for that distro in
wiki.xen.org (e.g. http://wiki.xen.org/wiki/Category:Host_Install) or on
the distros own wiki.

Hard to say, beside trivial recommendations. Many CPU cores are better 
than few, bigger RAM is better than smaller. Leave room for upgrade 
(second CPU, double the RAM, add disks) if you are trying not to spend 
too much. Depend a lot on the intended use. If the goal is just to test 
Xen, grab anything.

Make sure the CPU support virtualization and your storage system has a 
hardware RAID. Good idea to have 2 or more NIC ports, one for 
administration (and, maybe, storage) another one for the VM''s. The
usage
will tell you the rest.

I don''t think you could find any relevant general recommendation,
beside
reference of what people actually use for specific purposes.
