Hard disk drives
The server contains two hard disks, which are configured as a Linux SW RAID
1 pair, and they store server or cluster-related data. These hard disks are not
part of the customer-usable data storage that is available to the server.
Hard disks are located behind the bezel on the left side of the chassis.
Note: Failed hard disks are hot-swappable, so a failed hard disk can be
replaced without shutting down the server. However, there are serious risks
in trying to swap a drive that is not failed.
