I present them here for your unbridled enjoyment and pleasure:
update: Based on feedback from this post, we went back and improved our rack hygiene:
- 1U web servers (5)
2.83 Ghz quad core, 8 GB RAM, 2 drive RAID 1
- Primary 2U database server
3.33 Ghz quad core x 2, 48 GB RAM, 6 drive RAID 10
- Backup 2U database server
2.5 Ghz quad core x 2, 24 GB RAM, 6 drive RAID 10
- QNAP TS-409U network attached storage device
500 Mhz CPU, embedded Linux, hot-plug 4 drive RAID 6
- Netgear GS108T smart switch (2)
8 ports, gigabit, managed SNMP, web interface
- Netgear GS724Tv3 ProSafe switch
24 ports, gigabit, managed SNMP, web interface
- Tripp-Lite RS-1215-20 12 outlet power strip
seriously? it's a friggin' power strip. Oh fine.
Note that the primary database server is shared across all sites; only two of the web tier servers currently serve Stack Overflow. We have quite a bit of extra capacity in the rack.
If you'd like to see more, you dirty hardware perv, you can peruse a more detailed breakdown of the internals of the servers in Stack Overflow Server Glamour Shots.
