Upgrading Your Server 9-65
Disk Array Controller
The disk array controller board N8103-81F is an optional PCI board provided to improve the data
reliability.
The installation of this board enables the hard disks in the 3.5-inch hard disk bay of the server or
those in an optional disk expansion unit to be used in the disk array configuration.
