NOTE: If higher performance, higher availability, or higher capacity is required, arrays can
be moved from the Integrated Smart Array Controller to a higher performance array
controller without requiring a backup-and-restore procedure, but only if relative drive
order is maintained. If relative drive order is changed, or if no data backup exists, perform
a full backup before moving any array to another controller.

Controller Interface

The Integrated Smart Array Controller server interface is a Peripheral
Component Interface (PCI) bus. The PCI bus is a high-performance, 32-bit bus
with multiplexed address and data lines. It includes a parity signal and
provides a high-speed path (up to 132 MB/s) between the system board and
the array controller. The Integrated Smart Array Controller is a PCI Bus
Master device and conforms to PCI Local Bus Specification, Revision 2.2.
