You need that? I thought one of the religious HV vs. ESX points was that ESX overcomitted RAM i.e. allocates what a VM is actually using, not say the 4GB it thinks it has.I'm crossing my fingers that 48GB will be in my price range next year
Until 6 months ago i hadnt touched Citrix Xen. Now we have a fully home grown openfiler iSCSI san - citrix xen environment. That 6 months includes trialing, learning, implimenting and testing, and probably 4 of those months were spent on Openfiler rather than Xen.
Persoanally i wouldnt dismiss it out of hand because you dont know it, aslong as you click a mouse on the really simple GUI there really is nothing to learn (not at the home user level anyway)

For your ref, and perhaps it'll clear things up... With proper ESX you also need a management server (windows with SQL and a seperate DC (both can be VMs running on the system)) called vCenter. This is a single point of contact (for vSphere clients) that you add your ESX hosts too. vCenter does all the work in a production environment controlling licencing, vmotions etc etc. vCenter is pretty expensive, but under 3 hosts and you get get a 'foundation' licence that is about 1k.
Look up the 'ghetto' scripts for ESXi... you can do some stuff Xen offers for free where MS/VMware charge. Not sure you need migrations for 1 server tho.

Most of the stuff re: ESX, management, licenses, cost, etc.. kicks in when you're dealing with multiple hosts and trying to juggle it all... Sort of the KVM switch of the VMWare world... Ok that makes a lot more sense...
Well that was my next thought, ie: migrating a VMWare to a Xen... I'll have the old server (once I transfer it all off) to play with anyway so I may just stick Xen on that when there's more time.. Doesn't hurt to have another skillset or experience... There's just so little time!Look up the 'ghetto' scripts for ESXi... you can do some stuff Xen offers for free where MS/VMware charge.

ESXi IS ESX without the Linux Console VM. ESXi also happens to have a free version that lacks many features that are common to both ESX and ESXi when *licensed* (them having virtually identical features).
The minor differences:
ESX can provide guest access to COM/USB ports
ESXi can be run from USB/Embedded
Both have the same level of managability when used with vCenter.
Oh, and for testing I do recommend the ML115, I have one here for ESXi - cheap and mostly works with ESXi/Xen/Hyper-V

VMware's website isn't exactly clear on which version you're likely to end up using:
However the VI3 page says:VMware ESXi is the easiest way to get started with virtualization—and it’s free.
Lets add vSphere and Clouds into the mix just to confuse everyone!Customers (of the paid-for version) can choose to deploy either VMware ESX or VMware ESXi.
DMcCoy - Thanks for clarifying, my mistake!

Finally got myself organised and got one ordered... Had a horrible scare with my old server system and main PC that left me looking at a complete reinstall scenario with newborn baby screaming, etc... in background.
Me thinks £258 is a small price to pay for a bit of pro-active work... Now just got to update my MS Partner subscription..
