Chapter 4: RAID Configurations

This chapter describes how to set up, configure and use the 2Gb SANbloc Series RAID Controller. Some general infor- mation about the RAID controller is also provided.

2Gb SANbloc Series RAID Controller Introduction

The 2Gb SANbloc RAID Controller is a high performance

controller, providing two host fibre channel and two device fibre channel interfaces. It is an intelligent, caching controller that supports RAID levels 0, 1, 3, 5, 0+1, and JBOD. The controller enables multiple hosts to access an array of disk drives, which can be configured as one or more virtual storage devices (logical units).

The controller provides continuous access to data in the event of a disk drive failure. When configured in a dual- active controller system, the RAID controller also provides continuous access to data in the event of a controller failure. This dual-active controller system is one in which two controllers share access to the same array of disk drives. In the event of a controller failure, controller opera- tions are assumed by the surviving controller through a failover process. The failed controller can then be removed and replaced while the system is online. The new controller resumes processing array operations in a failback process. During failover and failback, write cache coherency is maintained with the disk drives.

Three circuit boards make up the RAID Controller:

•Controller: The controller circuit board contains the main controller and peripheral functions, including processor, control-store memory, XOR engine and cache controller, and
