Description
The redundancy mode, also called the "operation mode."
• Active-Active ULP: SAS only. Both controllers
are active using ULP (Unified LUN Provisioning),
which means 128 LUNs are available for mapping
volumes.
• Active-Active: FC and iSCSI only. Both controllers
are active, and each has 128 LUNs for mapping
volumes owned by that controller only.
• Independent Cache Performance Mode:
Cache mirroring and failover between controllers is
disabled, which results in improved write performance
but at a risk of loss of unwritten data if a controller
failure occurs while there is data in the controller's
cache memory.
• Single-Controller: There is only one controller in
the enclosure.
• Redundant: Both controllers are operational.
• Operational but not redundant:
In active-active mode, one controller is operational and
the other is offline. In single-controller mode, the
controller is operational.
• Redundant with independent cache: Both
controllers are operational with cache mirroring
disabled.
• Operational: The controller is operational.
• Down: The controller is installed but not operational.
• Not Installed: The controller is not installed.
