Sorry to ask, i couldn't find any posts related to my question. Im going to soon, well planning to have colocation with a unmetered 100Mb port. I want to host only Linux VPS and Deticated servers. For deticated servers I have no problem just buy some of Pentium 4 servers and so on.
But I have a questions about for the vps services. Im planning to buy a brand new server that would cost from $1000 to $1800. That is kinda my budget for the new vps server. But down to the questions...
What kind of cpu that would be good for vps, cheap and good. Intel Xeons or AMD?
What would be good for about 13Ghz total cpu for a server?
Im planning to have about only 12 vps on each server (12 customers) each customer has 1Ghz and 1GB RAM.
GHz or number of cores really mean less and less today.
If you are buying 1U servers and trying to sell VPS from virtualization, best choice for performance per watt per dollar is the Nehalem Xeon 55xx series, notable choices include E5504, E5520 and L5520.
Anandtech recently did an article with exactly your question in mind, although the author had always been strongly AMD biased, he did come to the same conclusions that L5520 is the best for the money today.
Dual-Quad's is what I'd recommend with a minimum of 12-16GB of memory. The more you stack on it originally, the easier it will be on you down the road.
We have learned over the years that it's so tempting to spend a little less now but in 3 months... We're wishing we'd have spent the extra money Plan ahead for growth and the unknown. You want to allow for some cushion.
You're not going to wrong with either Intel or AMD. The new Nehalem's and Xeon's are working great for Virtualization and AMD has always made a strong processor that works well with Virtualization. You'll be good either way.
