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 to the management-console functions, especially for storage
environments that use encryption, an additional management console is provided. For models 994 and
996, a 1U keyboard and display (feature code 1765) is required. The 1U keyboard and display is optional
for model 993.
Note: The 1U keyboard and display (feature code 1765) is not available with the model 993 ZR1
installation (feature code 0937) or LR1 installation (feature code 0938).
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 node, 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.
Storage server
The storage server consists of two processor nodes, two or more I/O enclosures, and a pair of power
control cards.
Processor node
The processor node controls and manages the storage server functions in the storage system. The
two processor nodes form a redundant pair such that if either processor node fails, the remaining
processor node controls and manages all storage server functions.
Power control card
A redundant pair of power control cards located in the Management enclosure coordinate the power
management within the storage unit. The power control cards are attached to the service processors
in each processor node, the primary power supplies in each frame, and indirectly to the fan/sense
cards and storage enclosures in each frame.
Flash drives
The storage system provides you with a choice of drives.
The following drives are available:
• 2.5-inch Flash Tier 0 drives with FDE
– 800 GB
– 1.6 TB
– 3.2 TB
