This is just a simple list of hardware and part numbers we have for the cluster. It's getting hard to keep track of our toys. If you're looking for machine MAC addresses, go /wiki/spaces/RAM/pages/6848587 instead.
Cluster Configuration
Special Notes
Special notes about rc01-rc80:
- rcmonster augmented with a Crucial M550 1TB SSD (Jonathan, 2014-05-26)
- rc56-rc64's second (right) drives have been replaced with Crucial M550 1TB SSDs (Jonathan, 2014-05-26)
- rc01-08 have their secondary NICs connected to the switch and are accessible via the hostnames rcXXb (i.e. rc01b) (Stephen, 2016-8-23)
- Note: After a reboot or rczap, one will have to re-enable the network device via "ifconfig eth1 up && dhclient eth1 && ifconfig eth1 | grep inet"
