The space currently uses a lot of old, power hungry hardware and could be optimised by the addition of a small amount of money to refresh the infrastructure. This page stands to collect the ideas on how and what to do with performing this task.

Proxmox Servers

These systems take a lot of power (3 pieces of about 200-400W a piece) (confusion , precious , anotheroneikeepforgetting )

Usage

We run a copious amount of virtual machines on our Proxmox cluster

Replacement

Not sure if this is totally viable, but :

This quadcore CPU has full VT extensions, but is just 10W TDP! For 99% of our VMs, this is probably already a sufficient host. Motherboard has a max of 16GB (in 2x SODIMM DDR3 1866mhz)

Questions

  • How is the reallife performance?

Netapp

The Netapp storage has been identified as a power consuming piece of hardware. It is also FAILING STEADILY so this is important to upgrade!

Usage

This machine is primarily used for NFS mounts across the infrastructure.

Replacement

  • The0 has a 3u case/machine with 12 disk hardware RAID controller (controller has broken ports) with brackets but without disks in it that might make a good replacement.
  • We could construct a JBOD and do software RAID - using the an ASROCK c2750d4i is a good starting point but it is kind of expensive.
  • Maybe 3 old atom boxen with each 4 disks and something like ceph might also work?
  • Or buy a new motherboard and use zaryas 4 port Areca controller

Questions

  • What type of FS do we want? (ext4, XFS, ZFS)
  • Can we do HA somehow? (ceph?)
  • What OS?
