Re: Need advice on a new midrange.com server config

For simplicity's sake I'd say go with a single Linux install. However,
simple isn't always better. Going the VM route gives you the ability to
manage your workloads with more granularity. VMs also give you some
insulation against dependencies or compatibility issues that could come up
later. For instance, if a new version of one app comes out and it's got a
feature you really want, but it requires an upgrade to the kernel or to the
underlying database that you can't upgrade because another app isn't
compatible with the upgraded kernel then you're stuck.

An alternative would be a blended approach: Set up a VM architecture so you
have the ability to do multiple VMs but start with a single VM that runs
everything. That way, in the future should you decide you want or need to
split workloads or create a test environment you're already laid the
groundwork and you just have to create the new VM (and not reload the server
as a VM).


I can't recommend a VM platform as I've little experience with them. My
employer uses the expensive version of VMWare as we've got hundreds of VMs
across dozens of physical boxes. Between physical & virtual we've over
1,000 servers.


As for the hyper threading question, consult the docs on the VM platform for
their recommendation. If they have none, then enable it. Modern HT is much
better than the original HT implementation.

Another thing ... I ordered the machine with 4gb of memory with the
intention of upgrading it myself.

It will arrive with 2x2gb DDR3-1333 ... I could get another 2x2gb dimm's

Thanks!
