Sun StorEdge A1000 Hardware RAID
Controller Module
The Sun StorEdge A1000 hardware RAID controller module is a compact unit
designed to provide high-performance disk array management services. The
controller module supports dual SCSI hosts on a 16-bit SCSI-2 bus. There are 2 SCSI
controllers inside the controller module that manage data distribution and storage
for up to 12 disk drives. The controllers perform system status and fault detection
functions as well. RAID 6.1.1 allows the user to reset the disk array in different
RAID configurations.
The Sun StorEdge A1000 controller module comes with two 4MB Single Inline
Memory Modules (SIMMs) for program memory and two 8MB SIMMs for data
cache memory installed and two UltraSCSI connectors (68-pin) for the host
connection. Data cache memory is a memory buffer on the controller used to support
the Write Cache feature of RAID Manager, the disk array management software.
The standard configuration contains 24 MB of DRAM, upgradable to 80 MB DRAM.
See "SIMM Upgrade Procedure (A1000 only)" on page 30.
