A quick preview of the update I did over the years of my first home server. I scavenged the web to find second-hand electronics, hard drives, racks, routers, cables, SAS controllers, GPUs, CPUs and motherboards. I replaced almost everything from the original design to allow the current polling to have:
- added exhaust fans for better cooling during summer (hard drives do not like to go over 40°C that much.
- a robust 2-drive pool (each 12 drives). One pool for hot data / production. One pool for local backup in case of bit root or user error (I am planning to have the backup on another, physically separated rack in the future).
- a total of 261 TB of raw storage capacity ; 10,91 TB hot spare, 218 TB usable, 109 TB for backup and 109TB for hot capacity.
- a robust ZFS system for each drive pool, formatted in RAIDZ-6 (2 drive redundancies for each, so 10 usable and 2 redundant capacity drives equivalent).
- a SAS backbone for drive shutdown of the backup pool during no usage times (saves 120W continuous power)
- an intel 7900K for AVX-512 processing (local llama), 58 PCIE lanes and ample transcoding power.
- a GTX 1050 (still, this did not change from the first build) for transcoding purposes
- a LSI SAS 24i SAS expander for internal disk connection (useful during the monthly ZFS scrub to reduce scrub time down to 20h approximately)
A more complete article will probably follow as soon as I have the time. In the mean time here is a quick gallery:
