Storage Processor (SP)

The SP provides the intelligence of the storage system. Using its own

operating system (called Core Software), the SP processes the data

written to or read from the disk modules, and monitors the modules

themselves. An SP consists of a printed-circuit board with memory

modules (DIMMs), status lights, and switches for setting FC-AL

addresses.

For high availability, a storage system can support a second SP. A

second SP provides a second route to a storage system, so both SPs

can connect to the same server or two different servers, as follows.
