| Jan 19, 2012 at 17:22 | comment | added | Mark S. Rasmussen | Write cache is enabled for all LUNs, default settings across the board. I don't think it's cache related as even the NUL backups show problems - thus eliminating write issues. For reading, each controller has 2GBs of read cache, plus the memory on the host (which has an infinite PLE given plenty of memory). | |

| Jan 19, 2012 at 14:46 | comment | added | Mark S. Rasmussen | The data files are on a dedicated 6-disk RAID10 LUN. The backup files are stored on a separate LUN. So far I see no indications that the backup drive/files are affected, it only seems to be the data drive. | |
