ALICE crunch server WIP

This page contains an overview of the machine and an everyday log of what is being done. Later there will be more accurate documentation.


The machine has 3 disks.

  • One M.2 (SSD) for boot and system in raid 1 with the one below (3 copies of the system, but we will see if of any use)
  • Two U.2 (SSD) in RAID1 for user homes
  • a large capacity RAID6 for data, ~60TB

See description in this graph below.

One can login to the machine as it does with aurora.

Additionally admins can login to a separate monitor machine to check the status of hardware components. This machine will also send warnings in case of issues.

Florido will take care of OS installation and hardware maintenance/monitoring. This info will be shared with ALICE admins. ALICE admins will have access as root and control any parameter they want.
