System architecture overview
The overview describes the architecture of the storage system.
Hardware architecture
The basic system architecture of a single controller is shown in the following
diagram.
In this architecture, the virtual storage directors (microprocessors) are
shared across the cache, front-end directors (host adapters), and back-end
directors (disk adapters), providing processing power where and when it is
needed, without wait time or interruption. This significantly increases the I/O
throughput, up to three times the speed of the VSP system. The system
provides a highly granular upgrade path, allowing the addition of drives to
the drive chassis, and components such as virtual storage directors to the
controller chassis as storage needs increase.
