Inventory of how the Manoa cluster is used and some details of the hardware.

Nodes criticalness

When necessary, the nodes labeled 1 can be shut down first. Then, the nodes labeled 2, and so on...

• 1: Can be shut down. Not necessary for operations:
  • poi00 (offline now ipp000, master, nkbf0, alala)
• 2: Could be shut down but necessary for full operations.
  • ipp003,
• 3: Shouldn't be shut down. Absolutely necessary for operations.
  • ipp001, ipp002, ipp022, ippops1, ippops2,
• 4: Shouldn't be shut down unless data shuffle not needed
  • ippb04, ippb05

All systems should have sensors available to check temperatures. Temperatures also available on the ganglia plots ​http://ganglia.pan-starrs.ifa.hawaii.edu/?c=IPP%20Development

ipp000

ipp001

• dumps of gpc1/ippadmin/isp, daily, every 4 hours
• mysql data base for ifa pstamp request and development test data store
• ippMonitor/transients/ippBlog
• proxy
• has idl
• mysql slave
• 4 cpus/ 8gb
• 8 TB

ipp002

• has some files from rsync server (the big threepi db)
• svn/trac
• 4 cpus/ 8gb
• 8 TB

ipp003

• rsync server
• proxy
• 4cpus/ 8gb
• 10 TB
• transients DB/name server

ipp022

• rsync server
• has idl
• 8 cpus/ 16gb
• 20 TB
• datastore (IfA users postage stamps request) -- Very small. Bill says could be moved to ipp001
• ipp build for running data store and IFA postage stamp request submission scripts. Bill says it could be moved.

ippops1

• ipp datastore/pstamp proxy to ippc17

ippops2

• ganglia monitor server

master

• IPP gentoo OS (portage and driver) development

poi00

• IPP NIS secondary

nkbf0

• rsnapshot server (HW raid controller flaky, ARC-1170 PCI-X)
