We are currently running at reduced capacity, with only two of four chillers running. After inspecting the chilled water pumps and the pump controllers, we determined that the condenser water pumps are fine, and that two of the four cooling tower water pumps failed. We are pulling these pumps out today (July 17) to determine whether they can be repaired. If the time to return them to service is too long, we will consider bringing in a portable cooling tower to augment our existing system. Until we have more information, we do not know when the facility will be back to full capacity.
The current status of NAS resources is as follows:
| Pleiades | Half capacity |
| Westmere | Half |
| Westmere GPU | Full |
| Sandy Bridge | Half |
| Ivy Bridge | Half |
| Endeavour | Full capacity |
| Merope | Down, but targeted for full capacity |
| Maia | Down |
| Mira | Down |
| Hyperwall | Down |
| Filesystems | Up |
| Archive | Up |
