This area contains slides of talks and reports on work in progress on the IceCube StorHouse HSM system. If you are not one of our collaborators, you are not entitled to review this material. It contains preliminary work which can be inaccurate, and only members of our collaboration are in a position to determine accuracy.

• Various documents
• 05Apr2011 : Copy rates out of StorHouse
• 06Apr2011 : Copy rates StorHouse to disk
• 21Apr2011 : Data usage by experiment and year
• 04May2011 : Data layout for 2010 IceCube
• 06May2011 : Notes about new RFS software.
• 12May2011 : Ingest speed w/ new RFS software looks pretty good.
• 19May2011 : 3 simultaneous ingests overcommits the disk. Speed is OK
• 26May2011 : annotated rfs.cfg fragment
• 31May2011 : Multiple ingests running with small areas.
• 07Jun2011 : Nagios plots for sam ingest.
• 10Jun2011 : Decreased network contention doesn't noticeably increase ingest rates.
• 14Jun2011 : Using the fast disk changes the ingest speed by a factor of 3, and the temporary collection failure messages go away.
• 15Jun2011 : Larger collection areas by themselves (with no other tuning) do not prevent temporary collection failures on the slow disk.
• 16Jun2011 : Symptoms of misconfiguration
• 24Jun2011 : Limiting factor seems to be disk speed. 2 active ingest collectors is probably max.
• 28Jun2011 : Report for Zeuthen
• 05Jul2011 : rsync job fails. Mysterious spikes in data rates
• 06Jul2011 : More details on resource use on sam
• 11Jul2011 : New version of rsync works better.
• 12Jul2011 : sam crashed.

These slides are presented here for the use of IceCube collaborators; both for quick communication during phone conferences and for archival purposes. They refer to internal development work, and are not intended for publication to the general public. As of this date none of our collaborators are blind, and since none but our collaborators are likely to benefit from reading them, I see no purpose in making the postscript files accessible to the blind.
