I ask because I have a fair number of these just sitting around and it would be nice to see them being used in my virtualization project. I''m not sure however if these are adequate for much. The machines I currently use are 8-way/32GB so quite different from these so thought I would ask. Thanks for any input you may be able to offer.

Re: [Xen-users] Anyone using dual 3Ghz/4gb servers?
As you seem to want to be able to migrate, you should be aware that you can only migrate between the same architecture (e.g. 32/64 bit, Intel/AMD) and even within a family, there seem to be limitations. The topic has been addressed here previously with links to in-depth discussions. If "...a fair number of these..." means that they are similar, then that''s ideal! Other than that, if the servers are worth the power they consume - I''d say just go ahead!

You could almost certainly put them to use - how useful they''ll be will depend on what you need them for. Like someone else mentioned, migration may or may not work between those systems and your 8-way ones. Also, if those 2-way systems don''t have VT capability you''ll only be able to run paravirtualized guests - you won''t be able to run HVM domUs (which rules out Windows and a few others). -Nick>>> "lists@grounded.net" <lists@grounded.net> 2009/01/21 22:08 >>>I ask because I have a fair number of these just sitting around and it would be nice to see them being used in my virtualization project.

The machines are all IBM so they will be similar in many ways.> Other than that, if the servers are worth the power they consume - I''d say > just go ahead!Well, that''s what I''m not sure about and is why I was asking if some folks are using such machines and if so, do they find them adequate for their purposes. Hearing others input, you sometimes realize that there is something you can do.

I use a machine like that for one of my beta machines, and it was the first machine that I installed Xen on. Depending on the age and the bios version you may not be able to do HVM but paravirtualized stuff works fine.

Just kinda wondering how useful they are since they will in fact use up more power than the 8-way machines but will be individual servers. For example, aside from power requirements: One, 8-way 3.0Ghz Xeon server with 16GB to 32GB memory. vs or equate to; Eight, dual 3.0Ghz Xeon servers each with 4GB memory, expandable to 8GB. Trying to get a handle on what would be best to use. Most of the services will be LAMP based with a smattering of various other redundant services such as DNS, etc. Mike _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi Steve, The machines are IBM blades, HS20 to be exact.

As far as the 2-way systems go, the machines I use for Xen virtualization are 2 x Socket, 4 x Core per Socket. I don''t know if that makes them 2 way machines or 8 way machines, but they''re definitely on the lower end of the server range and they work great for me. Sounds like yours are new enough that you should be able to use them without a problem. -Nick -----Original Message----- From: lists@grounded.net <lists@grounded.net> Reply-To: lists@grounded.net To: xen-users <xen-users@lists.xensource.com> Subject: Re: [Xen-users] Anyone using dual 3Ghz/4gb servers?
