The Hsz80 Array Controller - Compaq StorageWorks HSZ80 Configuration And Cli Reference Manual

The HSZ80 Array Controller

Your controller is the intelligent bridge between your host and the devices in your
subsystem.
Figure 1–2. Bridging the Gap Between the Host and Its Storage Subsystem
The controller shown in Figure 1–2 is an integral part of any storage subsystem
because it provides a host with high-performance and high-availability access to
storage devices. See the HSZ80 Array Controller ACS Version 8.3 Release Notes for
the most recent list of supported devices and operating systems.
The controller provides the ability to combine several ordinary disk drives into a
single, high-performance storage unit called a storageset. Storagesets are
implementations of RAID technology, which ensures that every unpartitioned
storageset, whether it uses two disk drives or ten, looks like a single storage unit to the
host. See Chapter 3 and Chapter 4 for more information about storagesets and how to
configure them.
