Controller chassis

The controller provides system logic and control, memory, and monitoring, as
well as the interfaces and connections to drives and host servers.
The 10U-high controller chassis consists of Virtual Storage Directors
(microprocessors), cache path control adapters, cache backup module kits,
front-end directors (host I/O modules), service processors (SVP), ten cooling
fans, and up to four power supplies. In a system with drives, the controller
also contains at least two back-end director pair. All components are installed
in redundant pairs so that if any component fails, the mirrored component
will handle the load and the system will continue to run. Any component,
including the operating system running on the SVP, can be replaced or
upgraded while the system is in operation.
Clusters
The controller is logically divided in the center. Each side of the controller is a
cluster that works in parallel with the other cluster. The virtual storage
directors, front-end directors and back-end directors, cache, and cache
backup kits are installed symmetrically across the two clusters and work as
one system.
The following figure shows the front and rear views of the clusters in a fully
configured controller chassis.
