Time for an update....
Current setup as of 04/05/15 (UK date format).
Top to bottom:
Monitor/keyboard tray.
(back dell 5324 switch)
Low power virtualisation server (Xeon L5520, 24Gb ram, 500Gb drive)Runs Proxmox 4.1, although it is in a sopos email 1u case (aka a rebranded supermicro chassis) it actually has a Supermicro X8STi+ motherboard. using a riser to add an additional 2 NIC's
HP DL385 G1 - Archive server. (opteron 220, 4GB RAM, 6x 300GB scsi drives in raid 5 with hotspare) This machine is pretty old and entirly used for making weekly dumps from the FreeNAS machine as a sort of offline storage (ignoring another machine offsite)
Sun X fire X4170 M2 - virtualisation (2x X5650, 96GB RAM, 4x 146GB SAS in Raid 5) (Ikaros)A more recent acquisition entirely so I could compact my older Ikaros system from a 4u to a 1u system. Also runs latest Proxmox. Runs a huge bulk of VM's and is hooked up to two networks providing servers for both.
FreeNAS - Storage (Asuna (she's grown a little fatter)) (2x L5520, 48GB RAM, 6x 2TB in Zfs raidz2) got some other disks to go in it, 3x 4TB woooo. Asuna.... got fat, almost a year ago I acquired the Supermicro cs824 chassis. It was an old ex-enterprise unit that had some "disk issues". Which basically turned out to be the SAS expanding backplane giving up the ghost. Now all disks are directly attached (mess of cables) into LSI 9240-8i (flashed as a 9211 IT) and a 9211-8i.
Finally a APC 3000 smart ups, a 2.7Kw capable unit. Got it for free and replaced the batteries, works solidly.The APC unit actually came with the rack (along with two really old fujitsu servers) and was basically dead. Took a gamble on purchasing new batteries for it (8 in total and close to £100) and magically it sprang back to life. The network management unit on this model is a bit flakey and keeps resetting passwords (???). Although it can sustain a 1.4Kw draw for about 20 minutes on battery, which is fairly impressive. Seeing as the machines mostly draw on average 400Watts it can keep them on for a long time.
