7. In the Repository Size window, provide the following information:
a. In the Repository size (TB) field, enter the repository size (in terabytes)
that you determined using the Create repository planning wizard.
b. In the Estimated factoring ratio field, enter the estimated factoring ratio
value that was determined with the assistance of IBM Support personnel.
c. In the System peak throughput (MB/Sec) field, specify the rate of system
peak throughput that the meta data file systems can support.
d. In the MD Raid configuration field, select the RAID configuration of the
logical volumes on which the repository meta data file systems are to be
created. For example, select FC-10K 2+2 for a configuration of RAID 10
2+2 with Fibre Channel 10K rpm disks.
e. In the Disk Size (GB) field, from the drop-down list, select the disk size
that is the closest match to the disk size of the server on which the
repository is being created. If an exact match is not available, choose the
next larger value.
8. Click Next.
The Storage window opens. See Figure 45 on page 125. In this window, the
Allocated meta data size field displays (in gigabytes) the amount of disk
space allocated for meta data. The Allocated user data size field displays, (in
gigabytes) the amount of disk space allocated for user data, based on the
estimated factoring ratio and the set of existing file systems.
