ta transfer speed between primary and secondary arrays
Bandwidth of data transfer paths
The bandwidth (that is, the data transfer speed) of data transfer paths between the primary and
secondary arrays depends on your environment. The bandwidth must exceed the data transfer speed in
“normal status” mentioned previously.
Journal transfer speed of DKCs
A DKC's journal transfer speed depends on the number of paths used for transferring journals. The
number of paths for transferring journals must be large enough that the journal transfer speed exceeds
the data transfer speed in the “normal status” mentioned previously. The maximum number of paths for
each pair of the primary and secondary DKC is 8.
NOTE:
If the jo
urnal transfer speed falls short of the desired speed, check the channel processors' usage rate.
If the us
age rate of some channel processors is high, the journal transfer speed might increase if you
add channel processors.
Configuring primary and secondary arrays for Continuous
Access XP Journal operations
After installing the Continuous Access XP Journal hardware and software, you can configure the primary
and secondary arrays for Continuous Access XP Journal operations.
1. Identify the Continuous Access XP Journal data and journal volumes in the primary and secondary
arrays. You must know the array's S/N and port ID, so you can confi gure the primary and
secondary arrays correctly for the desired pairs. When creating pairs, you must know each volume's
port, target ID, and LUN.
2. Connect to the local array you want to use. For more information about Command View XP or XP
Remote Web Console installation and operations, see the HP StorageWorks Command View XP
user guide for XP Disk Arrays or the HP StorageWorks XP Remote Web Console user guide for
XP12000/XP10000/SVS200 or contact your HP account support representative.
