Hi Everyone,

I am in the process of acquiring new disk which means that I will be able to 
layout the storage for the database, log and storage pools in a more efficient 
manner.  I was told by IBM that a filesystem should contain no more than 2-3 
volumes and there should be a 1 to 1 ratio of physical disk volumes to TSM 
volumes.

I was thinking about doing the following but I was wondering if there is a 
known limit to the size of a volume that should be used for the database or 
storage pools?  And should I have more storagepool volumes created per 
storagepool?

Any suggestions/opinions are greatly appreciated!!!!

3 filesystems that are 50 GB each with 1 physical 50 GB LUN with 2 TSM database 
volume per filesystem:

Filesystem                          Volume                Size (GB)
/tsmdev/db1                     dbvol1                  25
                                              dbvol2                  25
/tsmdev/db2                     dbvol3                  25
                                              dbvol4                  25
/tsmdev/db3                     dbvol5                  25
                                              dbvol6                  25

For my log volumes I'm just going to create 1 filesystem with 1- 15 GB lun and 
then create 3- 4 GB log volumes from it:

Filesystem                          Volume               Size (GB)
/tsmdev/logfs                   logvol1                  4
                                              logvol2                  4
                                              logvol3                  4

Storage pools:

Filesystem                          Volume                                Size

                       Represents vol2 of Oracle storagepool
/tsmdev/stgpool4           vol7                        125

   Represents vol1 of Windows storagepool
                                                Vol10                     200   
                      Represents vol2 of Windows storagepool

                      Represents vol3 of Windows storagepool
