The capacity required for the shared disk for shared data of AdvancedCopy Manager's agent is as follows:

Table 7.5 Capacity of shared disk for shared data of AdvancedCopy Manager's agent

Transaction Type	Disk Space Required
Managed Server transaction	The total value of 1 to 3 below

1. Replication operations

   • If the number of paired replication source/replication destination volumes used for a replication operation is p, use the following formula:
     1.1 * p [KB]

2. Backup operations

   • If the number of backup volumes is "a", the number of transaction volumes is "b", and the number of DSIs of all database spaces to be backed up is "c":

     • When backing up Symfoware:
       ((a + b * 35) + (b + c * 0.5)) / 1024 [MB]

     • When not backing up Symfoware:
       (a + b * 35) / 1024 [MB]

3. Capacity required for cluster operation management data

   1024 [KB]

Note

If a single shared disk is to be used for both the repository and the shared data, add the size of the shared disk for repository (partition, etc.) that will coexist on the shared disk for AdvancedCopy Manager shared data to the abovementioned value.
