Moving from dedicated. openVZ, KVM or stick with dedicated?
| Posted by phactor, 08-05-2010, 12:04 PM | | Hello,
Atm i have about 6 dedicated servers ( xeon x3220 + 8G ram DDR 2 and 2x 500gb raid1 ) running shared hosting with cPanel. I'm about to change this servers to new boxes.
I'm thinking about migrating my customers from dedi to a vps. I will buy lets say 4 more powerfull servers (raid 10 and 10k / 15k RPM drives ) and create 8 or 9 vms. From a management point of view, and using a cluster with promox ve it will much better, as even allows live migration, for example if a have a problem in a node i can quicky migrate to another one.
However i dont know if i will loose stability and power if i migrate to a VPS. Whats your suggestion? I'd better keep with dedicated servers to have more power, or a few vps with 4 / 8gb of memory and a faster raid will give me more performance?
Regarding the technology, what will give more more performance / security ( openvz or kvm )? This will be all linux servers for now.
For the record, i already have two servers running about 40 openvz vps and they work fine.. but i want to offer something reliable to my customers.
Please share your opinions.
thanks

This is neat stuff: http://www.linux-kvm.com/content/usi...ge-merging-kvm
