Hello
I have a p720 server with AIX 6.1 installed. Back end Storage is on a DS4800 behind a SVC. I am going to be using SDDPCM as we currently do that on a p520 server running Aix 5.3.
Our existing production TSM 5.5 Server's database is 150GB (130GB used). I'm not doing a migration as I plan on moving clients over to the TSM 6.2 server in small quantities.
The p720 is a single 8-Core CPU with 32GB Ram (in case we decide on dedup)
My initial thoughts on DB2 sizing are:-
Directories
/opt/tivoli/tsm/db/dbdir001 100GB
/opt/tivoli/tsm/db/dbdir002 100GB
/opt/tivoli/tsm/db/dbdir003 100GB
/opt/tivoli/tsm/db/dbdir004 100GB
Active Log
/opt/tivoli/tsm/log/active 30GB ?
Archive Log
/opt/tivoli/tsm/log/archive 30GB (probably a bit on the low side??) I backup about 300,000 files a day.
dbvg will be the DB2 Dir Volume Group (4 LUNS - 1 hdisks / LUN)
actvg will be the DB2 Active Log Volume Group (1 LUN - 1 hdisk)
archivevg will be the DB2 Archive Log Volume Group (1 LUN - 1 hdisk)
Questions:
1. Is my archive log size going to be too small to cater for two full TSM DB2 backups?
2. Is the active log size overkill for 300 nodes?
3. Should I have more DB2 directories and smaller sizes?
I probably have more questions as I think of them.
Any feedback would be appreciated. Thank you.
