We now get into choosing hardware for that shiny new gentoo-server ... as mentioned this will be a KVM-host and we look at a HP Proliant DL385p ... 2 AMD Opteron 6344 ... 32 GB RAM, 8 disks (the customer has some bigger contract with hp, so we are a bit biased to hp here).
For the server that runs the VMs right now we back then chose 2 smaller SAS-disks for the OS (speed, expensive) and installed SLES on a mirror built on those 2 disks. The other 8 (?) SATA-disks run in a RAID-6 ... Now I ask myself if I want to do that again: 2 smaller disks, fast, RAID1 -> OS/ Gentoo (SSD? I think, no) 6 bigger disks, maybe 7200rpm, SATA -> RAID6 -> LVM -> space for VMs (maybe straight LVs for the VM-disks ... performs well, nice backups) Or should I go for all 8 disks in a RAID6 ... ? I'd like to discuss that and hear your opinions and experiences. Thanks!
