Hi there

We need to virtualize about 4 servers with some mysql (about 6 DBS' with 400mb each) and mail (moderate) use. Someone know if this will be a good configuration ? or can suggest changes on it

dell 1950iii
2x quad core xeon 2.0
16gb ram with 400gb sas x 2 15k / RAID 1
perc6i sas raid int pcie 256 cache
dual embedded broadcom nextreme 2

Or it will be better

dell 2950
2x quad core xeon 2.0
16gb ram with 250gb sata2 x 4 7.2k / RAID 10
perc6i sas raid int pcie 256 cache
dual embedded broadcom nextreme 2

thanks for your great work and also as usual thank u again!

I vote for the system with SAS drives.

What VM´s do you plan to run on Proxmox VE? KVM guests or OpenVZ containers?

I vote for containers.

Hi!

Don't know if anyone else have seen it, but I couldn't install Proxmox VE 1.1 using a perc6i controller before turning off the write-back cache in the RAID controller. I have three 300GB 15k SAS disks connected to the perc6i. RAID 5 or 1 produced the same result, install getting very slow at about 75-80%, when configuring packages. After that different timeouts happen and it finally fails. I think I was able to produce two working installations from about twenty tests, before turning the cache off. After finally figuring that out everything worked as a charm. After installation the write-back can be turned on again, for better IO speed. At least I haven't noticed anything strange after. The setup is not quite the same as the ones you list above though. I have two PE-2970 with AMD processors and an additional 4-port Intel network card. I must say I'm very impressed with the speed of OpenVZ containers on these two systems now.
