What will that CPU be like for a small openvz node?
Comments
Well it all depends on the servers that are on it and what they are hosting. If they are just running small things it will be fine. If you can on the motherboard you are using upgrade to dual quads Id suggest it, it is really cheap to upgrade.
The L5420 is also an option. I would not put any high ram customer machines on it, max of 1gb
I have a node with dual l5420's that are performing great, no matter that they are old.
I just ordered a batch of Intel Xeon 5150/60 both are good CPUs 5160 are 3.2Ghz but PLGA771 not LGA771.
They are not suitable for a production node, I would recommend a E5440 or L5420 over them.
L5420 will probably be better then
As we should all learnt, i/o is always the killer -> for a smaller node the CPU is fine. I guess you're asking this due to the Dacentec offer? They do at least offer 4*80GB -> smaller node -> fine
Perhaps go for a Dual E5520 or L5520. Pretty good value overall.
This CPU stuff is overrated.
A full small OVZ node as we have with SSD (typical one):

If you have fast storage and the CPU is not waiting on IO, the load can be handled by smaller CPUs, if you have a lot of iowait, no matter how good the CPU, will still spend the same amount of time waiting.
