When multiple remote paths share a port, it is recommend that you set the same value of blocked path SIM monitoring time (time for watching SIMs reported when paths are blocked) for all remote paths.

The following table lists the setting items and their values, or supported functionalities for each transfer speed.

Setting item / supported functionality	25-Gbps Ethernet channel board	10-Gbps iSCSI channel board
Blocked path monitoring time¹	40 seconds³ (default)
Blocked path SIM monitoring time²	150 seconds	70 seconds⁴ (default)
Setting for enabling/disabling header digest and data digest	Available	Not available
Default setting for header digest and data digest	Enabled	Enabled
Transfer speed of the connection target port	25 Gbps/10 Gbps	10 Gbps
Redundant configuration of the remote path	Required	Recommended
Note: You can specify the setting by running the raidcom modify remote_replica_opt command with the -path_blocked_watch option specified. You can specify the setting by running the raidcom modify remote_replica_opt or raidcom modify rcu command with the -path_blocked_watch_sim option specified. If you shorten the blocked path monitoring time, the path might be blocked due to a cause of delay in the network (such as spanning tree algorithm of switches). Use the default setting.
