VRM Server name
Displays the iSCSI initiator name of the VRM device.
Password
Type the password which is set in the storage device; is required by the VRM device to
communicate with the storage devices; corresponds to the password, which is set for every
storage device.
Use as backup server
You can set up another computer as the master server, provided that the VRM device is
started on it. The existing configuration settings will then be continuously compared and
adopted for the VRM device.
System-wide CHAP password
Type the password of the master server.
Secondary target block allocation (GB)
Enter the number of 1 GB memory blocks that are allocated to a device on the failover iSCSI
target (secondary target). The minimum number of memory blocks for each device allocated
to the secondary target is eight. When carrying out this step, note that each VIP X1600 module
is counted as an individual device.
The retention time specified in the system also applies to secondary target memory blocks.
The number of secondary target memory blocks for a device should be selected in such a way
that there is enough memory space to continue recording for the required length of time if the
primary target fails.
Depending on the baud rate, you can assume that one block is sufficient for approximately
one hour of recording.
Memory blocks should remain free on the secondary target as a buffer. These are used by the
VRM system as memory if the blocks allocated to a device are insufficient.
Calculation example:
–
Memory capacity of the failover iSCSI target: 5,024 GB
–
Number of allocated VIP X1600 devices: 140 (each occupied with four modules)
–
Failover memory block allocation: 8 (minimum)
–
Resulting number of allocated failover blocks: 140 x 4 x 8 = 4,480
–
Resulting number of free failover blocks: 5,024 - 4,480 = 544
A buffer of 544 GB remains for recordings in case of a failover; this buffer is also available to
the allocated devices if required.

CAUTION!
Ensure that the VRM computer is synchronized. Otherwise you can loose video data.
Configure the time server software on the Central Server. On the VRM computer, configure
the IP address of the Central Server as time server using standard Windows procedures.
