Common guy interpretation?
Let me see if I can interpret this for the common person.
1- The fibre optic cables feeding the SAN were not optimally fitted -
How is this possible? There should be a "click" sound when the LC connector is fitted in. It's always been "insert" or "not inserted". I don't recall any instance where a FC cable can be halfway inserted. Maybe the cables were "bent".
2- Disk drives on the SAN had software bugs that made the stored data on the drives inaccessible or unable to be read -
If I can't read data on a disk, blame it on a firmware bug instead of a software bug.....
3- Some monitoring features were not activated, including a "back-to-base" tool to report operating errors -
When setting up - "ATO is a very very very secure site, I DON'T WANT CALLBACK! Disable callback! My peons will monitor this!"
Post mortem - "How did 12 disks fail without anyone knowing??? Didn't you promise callback??? Why is it not working????"
4- SAN design has overemphasis on performance features rather than stability or resilience -
When setting up - "I am on a tight very budget. Can you give me X TB usable by configuring RAID 5?"
Post mortem - "WHY ARE THE DISKS ON RAID 5??? These data are critical! I WANT THEM ON RAID 6 OR RAID 1!!!"
