Clone image file storage area
A clone image file storage area is required if cloning is to be performed.
Allocate area on the master server as an area to store the clone image files belonging to the cloned slave server (excluding slave servers built in virtual environments).
Note
Create the clone image file storage area at the Master Server local disk or at SAN storage. Folders on network drives, shared Folders (NFS, SMB, etc.) on other machines on the network, or UNC format folders cannot be specified.
The server used to create the clone image and the servers targeted as clones must be the same model. If there are different models, a separate clone image must be created for each model. Refer to the Note in "6.3 Adding Second and Subsequent Slave Servers" for details.
The method for estimating the space required as a clone image file storage area is as follows:
Clone image file storage area = Disk space used by one slave server * Compression ratio * Number of models
If actual results are available from a system build having the same software configuration, use the same disk size as that system. If one disk is split into multiple sections, use the total size used in all sections.
Use the operating system features to check the disk size used.
If actual results are not available from a system build having the same software configuration, make an estimation on the basis of the disk space given in software installation guides or similar.
This is the compression ratio when the disk area used at the slave server is stored at the master server as an image file.
The compression ratio depends on the file content, but generally a ratio of about 50% can be expected.
