Re: [Xen-users] HTPC + DUAL PC In one

Hello again Guys. I looked up that HP Microserver, it is pretty cool and cheap. Now I have a limited budged so i will remain on virtualized HTPC. Maybe in the future it will be useful.Â

Kristian thank you for the infos on CPU and Motherboard, i wasn't able to find them.

Ragarding unRaid, i read something about it. Is it a good idea to install it as Dom0? In such way it will manage the storage of all the VMs. Gordan what is a ZFS reciever?

It seems that i7 is more performant than AMDs... But the point is that using Xen and multiple virtual machines, i'll need more parallel calculus power, right? So 8 cores would be better? Is it possible that those benchmarks aren't done using all the eight cores of AMDs? Austin said that he can reach the calculus power of aÂdual processor Xeon E3-1286 v3. That's really a goodÂresult. So maybe i should choose AMD...

Another point is that one virtual machine will be for myself, the other one for my family. My family doesn't need much caclculus power, but in my VM i need the top calculus power i can get with my budget (500â, for CPU and motherboard, maybe something more in the future). What do you suggest?Â

I haven't tried any encryption, but I do use them heavily with ZFS, mostly 4-disk RAIDZ2. Receive always saturates the gigabit ethernet link and scrubs go at about 250MB/s. All my models are older N36L (1.3GHz) and N40L (1.5GHz), i.e. substantially less CPU than the most recent N54L (2.2GHz).
