Re: [PLUG] Recommend: cheap server suitable for virtualization?

[brainbuz <brainbuz@brainbuz.org>]

I run a fairly robust virtualization environment on a quad core amd processor in a mid-grade consumer motherboard. 

I'm running KVM and have had at times a lot of instability, I recommend running a current kernel as it seems to have settled down quite a bit with 3.2. 

For a server I do not recommend any kind of overclocking or unlocking, you have no way of knowing whether your locked core is defective. If you can get ECC RAM at close to the price of standard ram I recommend it, but it is often way more expensive. 

One thing I splurged a little on was an Adaptec RAID 6405E. If you're thinking about any kind of RAID, do it in hardware, and $200 for a real Adaptec SATA RAID controller that works out of the box with current Ubuntu is a no brainer. Yep you're going to buy a $100 MB and then spend $200 on the disk controller. When I added the Adaptec the system got a lot more stable than with fake-raid and the performance also improved. In fact for a database application an SSD did not result in a big performance gain vs the RAID-1 7200 RPM hard drives.

I have a VPS "in the cloud". I'd like to back it up to something at home, and it'd be even cooler if I could boot/play/mirror with it.
(It's a PAE kernel under Xen as far as I know).
What's a good/cheap hardware platform I can set this up on? (and then setup another VM to dev on?)

thanks
