A.2.3
Firmware LUN Filtering (RAID-Based Mapping)
LUN filtering is a method used for separating and controlling access to data from the
RAID controller. One major benefit of Fibre Channel is the capability to share a
common storage pool with multiple servers or workstations. However, allocation
becomes an issue when every server in a network can access the data in a logical drive.
LUN filtering provides a means for controlling data access if data is not allowed for
every server.
When you map a logical drive to a host LUN through the firmware application, you
can create a mapping according to the worldwide port names (WWPN) that are
specific to each host adapter. A LUN mask can then be created as an access filter for
including or excluding host adapters from addressing specific storage unit. A host map
is composed of an ID range that is configured to include one or more IDs. A host
adapter can be identified by its ID (device-specific port names) as included or
excluded from range. The LUN mask is also defined with a filter type as read only or
read/write.
A.2.4
Firmware Redundant Loops
The selection of “drive-side dual-loop” is fixed. Since two channels are used to
connect a group of physical drives, the two channels automatically assume the same ID
address and operate in duplex mode.
A.2.5
Firmware Dynamic Load Balancing
The controller provides a mechanism to equally distribute I/O loads between channels
in a redundant loop configuration.
