We need to configure a CMOD system to run on Linux. It's a sizeable requirement with the system having to satisfy a number of CMOD queries/retrievals per second at peak times. We need to size this system; that is decide on how many hardware processors, which processors and how much memory is required to give satisfactory fast response for the users.
One aspect to take in consideration, what do you call a "CMOD System":
- arssockd + arsload + DB2 + TSM(with DB2)
- arssockd + arsload + DB2 & SM is external e.g. different system aka cloud object store or remote TSM
- arssockd + arsload & DB2 or Oracle & SM remote
- arssockd & arsload on different system e.g. via ODWEK (though this is very unusual)
Also need to consider any other Services you may wish to run on the same box, such WAS/ICN, SAMBA (server and/or client), NFSd, sshd
Another question, how is the storage attached to the system, SAN, NAS or direct attached
As a rule of thumb I would say CMOD system is more IO intensive (Network & Disk) rather than CPU, but someone could argue that point. I am assuming moderate balanced ratio between need to compress and pre-compressed, as well as more searches than actual retrievals.
Well, here is my 5¢
