FC60 Single LUN ramifications

[Dave Fenner]

We have just installed a HP L series server with a FC60
disk array. The array is configured with dual fibre-channels, full-bus scsi, four enclosures with 4x36GB disks in each enclosure, (16x36GB array total). The array was brought on-line as a single LUN, 16 disk, 245GB logical volume, raid 0/1, primary and mirror drives on separate enclosures. I have suggested that this configuration will not load balance or utilize the second fibre channel but are there other problems with this type of deployment other than I/O?

If you would like to run at some point in time parallel backups you'll have to load ballance manually the directories to backup. The same story for restore.

I hope you don't have a huge numbers onf files/inodes (> 1 million). You'll face file system performace degradation.
Your DBA will not be happy finding out that he has all the redo logs, data files, indexes, etc on the same file system.
