Saturday 12 Nov 2011 – SAN Dedup affecting Performance

Saturday 12 November 2011

After 5TB of old “dedup” data was scheduled for routine deletion, at 12.07am one SAN node within the COY DC storage platform unexpectedly became intermittently responsive.

The decision was taken to take the storage node offline in an isolated fashion and perform a full data integrity check, which completed successfully and all servers utilising this SAN were reconnected for normal operation at 6.26am.
