UPS inventory for CCB Clusters and non-cluster HPCs

Note: Currently none of the clusters ChemIT manages have UPSs for their computer nodes.

UPS supporting both Synology storage system and headnode.

UPS USB-connected to Synology storage system. Synology thus sends a signal to headnode. Algorithms are:

  • Synology:
  • Headnode:

Synology's own s/w.

On Linux systems, running "nut".

Waiting for head node to deploy (on C4 at the moment)

Old UPS; on the margin

Baird: 1 rack-mounted computational computer

NONE
ChemIT recommended making this investment (standard of practice), but group decided explicitly not to make the investment.

Petersen: 2 rack-mounted computational computers

Yes, but needs to be deployed in true production; using Widom's UPS for now.
ChemIT using UPS for testing UPS-related control software.

UPS supporting both stem #50 and system #51.

UPS USB-connected to system #50, which itself does not send signal to system #51.

On system #50: Shutdown if only 10% battery power is left.

On system #51: No s/w running to listen for signal from system #50(if signal were to be sent).

Windows OSTo do: Establish sending a signal from system #50 to system #51 and have system #51 properly shut down in the event of a prolonged outage. 
Scheraga: 4 GPU rack-mounted computational computers

NONE
($900, estimate)
Need to protect? Data point: Feb'14 outage resulted in one of these not booting up correctly.

What does it cost to UPS a research

...

system?

Assuming protection for 1-3 minutes MAXIMUM:

Current goal: Do all head nodes and stand-alone computers in 248 Baker Lab. Started getting done, fall 2014.

Assuming protection for 1-3 minutes MAXIMUM:

About $180 (APC brand) per head node or server every ~3-4 years  (3 yr for warranty and ~4 years actual battery life).

  • Unusual case: And ~$900/ set of 4 GPU systems (Scheraga) every ~3-4 years (to for this, must confirm approach, appropriateness, and estimates).
