Storage complexes
A storage complex is a set of storage units that are managed by management
console units.
You can associate one or two management console units with a storage complex.
Each storage complex must use at least one of the management console units in
one of the storage units. You can add a second management console for
redundancy.
Management console
The management console supports storage system hardware and firmware
installation and maintenance activities.
The management console is a dedicated processor unit that is located inside your
storage system, and can automatically monitor the state of your system, and notify
you and IBM when service is required.
To provide continuous availability of your access to the management-console
functions, use an additional management console , especially for storage
environments that use encryption. Both management consoles share a keyboard
and display that are stored on the left side of the base frame.
Hardware specifics
The storage system models offer a high degree of availability and performance
through the use of redundant components that can be replaced while the system is
operating. You can use a storage system model with a mix of different operating
systems and clustered and nonclustered variants of the same operating systems.
Contributors to the high degree of availability and reliability include the structure
of the storage unit, the host systems that are supported, and the memory and
speed of the processors.
Storage system structure
The design of the storage system contributes to the high degree of availability. The
primary components that support high availability within the storage unit are the
storage server, the processor complex, and the power control card.
Storage system
The storage unit contains a storage server and one or more pair of storage
enclosures that are packaged in one or more frames with associated power
supplies, batteries, and cooling.
