Description
Data replication speed of a HyperMetro
consistency group.
l Low: Data replication takes a relatively
long time. This value is applicable to
scenarios where the service load is
heavy. The speed ranges from 0 MB/s to
5 MB/s.
l Medium: Data replication takes a
relatively short time. This value is
applicable to scenarios where the service
load is relatively heavy. The speed
ranges from 10 MB/s to 20 MB/s.
l High: Data replication takes a short
time. This value is applicable to
scenarios where the service load is
relatively light. The speed ranges from
50 MB/s to 70 MB/s.
l Highest: Data replication takes the
shortest time. This value is applicable to
scenarios where the service load is light.
The speed is greater than 100 MB/s.
Activation status of site. The value can be
Active or Passive.
HyperMetro domain to which the
HyperMetro consistency group belongs.
The data synchronization direction of all
HyperMetro pairs in one HyperMetro
consistency group. Including Remote to
Local and Local to Remote.
After the Isolation Switch is turned on, the
system will suspend the HyperMetro pair
when the difference between the write I/O
latency of the two storage arrays is greater
than the isolation switch. The storage array
with the longer write I/O latency will stop
providing services.
Write I/O latency difference between the
host and HyperMetro storage arrays.
