A.1.1 Key Features of the ICP Controllers of the GDT RS and RN Series
64 Bit Hardware RAID Controllers with RAID 0/1, or RAID 0/1/4/5/10 Array Drives at con-
troller level, completely independent of the computer system and the operating system.
Several Array Drives can be operated simultaneously.
Operation in 64 Bit and 32 Bit PCI slots. Full Bus Mastering. Maximum data transfer
rates: 132MB/sec in a 32 Bit PCI slot and 264MB/sec in a 64 Bit PCI slot (with RN Series,
only).
"Private" (i.e., for one Array Drive) or "Pool" (i.e., for several Array Drives) Hot Fix Drives.
Online Capacity Expansion. Add one or several new disk drives to an existing Array Drive
to expand its capacity. During the Expansion all data are redundant.
Online RAID Level Migration. Online change of an Array Drive's RAID Level, e.g., from
RAID 0 to RAID 5.
Online Capacity Expansion and RAID Level migration can be performed simultaneously.
