• Write In MB/s—The rate at which data is written to an array because of write activity to
the members of the source array. The write activity includes host writes, merges, and replication
retries. A merge is an action initiated by the source array to write new host data that has been
received and logged while a replication write to the destination array was interrupted, and
now has been restored.
• Write Out MB/s—The rate at which data is written from an array because of write activity
to the members of the source array. The write activity includes host writes, merges, and
replication retries.
• Free Write Resources—The minimum number of free resources available for DR write
operations.
• Free Copy Resources—The minimum number of free resources available for DR copy
operations.
• Free Command Resources—The minimum number of free resources available for DR
command operations.
HP EVA DR Group Information
The EVA DR Group Information object provides information about the performance of the DR Group
Write History Log (WHL) files. The performance metrics are provided for each DR group. The WHL
fill and drain rates can be displayed in either MBs or KBs.
Creation and management of DR groups is not supported by HP P6000 Command View array-based
management.
The counters are:
• Log full percentage—An instantaneous value representing the percentage of the log
disk which is used, in tenths of a percent. For example, 1000 is equal to 100 percent, and
10 is equal to 1 percent.
• Log fill Req/s—The rate at which requests to put data into the log disk owned by this
DRM group come in
• Log fill KB/s—The rate at which data is put into the log disk owned by this DRM group.
• Log drain Req/s—The rate at which requests to remove data from the log disk owned by
this DRM group to send to the destination via the DRM tunnel come in.
• Log drain KB/s—The rate at which data is removed from the log disk owned by this DRM
group to send to the destination via the DRM tunnel.
