hi.
Please help me with a decision. I like to know if proxmox is ready for production use and what is the performance when you use kvm only vm's.

I have a brand new server , intel Nehalem with Dual XEONS 2,4 (16 Cores) and 8 Gig RAM. Powered by 4 Velocy Raptor Disks and this Iron is really fast! (As an example: I Installed Windows 7 on Proxmox within 3 Minutes!) That brought the idea to test this hot iron in production use.
I like to run 3 W2k3 Terminalserver on this iron under Proxmox.
Is this config recommended? and what would the performance be ? really 3 % under physikal? or is this only for openvz?

2 Years ago i tried vmware server in production, but it was too slow so i had to roll back to physikal systems...


And another question:
how should i configure the hardddisks if i want to use 3 Servers in a cluster? is there something like loadbalancing possible?

Please help!

a few questions more:
what raid controller do you have? which configuration for the 4 hdds (300 GB each?)?
 
Master server:

RAID bus controller: 3ware Inc 9690SA SAS/SATA-II RAID PCIe (rev 01)

4x 150 GB SATA II WD Veloci Raptor 10000 U/min in a Raid 5

and we have 3 other servers, all nehalem (16 cores with 8 Gig RAM)
these servers have
3Ware 9690SA 4x SAS/SATA (0,1,10,5,50,6)
4x1000 GB SATA II WD Raid Edition III 3,5" in a raid 5

why do you use raid5? the suggested raid10 is more powerful in write speed.

as you talk about KVM, you can also think of use a SAN for storing the images (instead of local hard drives).

see http://pve.proxmox.com/wiki/Storage_Model

traditional way, yes. but due to the low prices of disks nowadays raid10 makes in most situations more sense: you can get up to double write performance in contrast to raid5.

but anyways, depends on the usage scenario. but for standard virtualization hosts like Proxmox VE where i/o is most times the bottleneck its the very best choice.

Actually raid 5 is falling out of favor due to large drive sizes. The time to write parity to the replacement drive is getting too long that having another drive fail in the meantime is becoming greater.

I setup a 8x2TB RAID10 array and it's fast, real fast, and since I bit the bullet and went with 2TB drives I can lose the storage.
 
Thanx for all the replies.
Actually i got a second netapp shelf so i can use the san solution.

But i got no reply to my question: Is proxmox ready for production use and what about the config?

I want to have 3 Terminalservers (w2k3) running under KVM. Would you recommend that?!

I see no problem here (I would use virtio for net and block on the win2003), assign one cpu to each guest.
io in the guest should be no problem as these are terminalservers.

there are quite a lot of win2003 around. most running with IDE and e1000 as this is stable since years.
