6.2 High Availability Characteristics
6.2 High Availability Characteristics
This section describes the redundant configuration of the power supply, Fan Tray, and System
Control Facility Processors, memory, PCI card, and System Boards. High Availability of the
main unit.
6.2.1 Redundant Configuration
The power supply, Fan Tray, and System Control Facility can be configured redundantly. If a
redundant system of System Control Facility is implemented, a second System Control LAN
must be added.
A redundant SMC configuration is available by installing a second SMC as a spare unit. The
Console Connection Unit can be also configured redundantly.
The file units can be configured to operate continuously. An accidental interruption such as disk
failure will not interrupt the user's business tasks by having to connect the disk array unit or
having to deploy disk mirroring.
6.2.2 Processors, Memory, PCI Cards
A degradation function in the power-on diagnostics and the dynamic degradation function while
the OS is in operation are provided. For more information, contact a certified service engineer.
6.2.3 System Boards
System Boards also provide the degradation function.
If you want to reduce the effect of degradation, you need a two-port connection in each partition,
both on-board LAN ports and the RS-232C port on the System Boards. For details, contact a
certified service engineer.
