I have a similar situation as Brian. 250 clients, running 4.2.3.2 servers on both a 9672-R52 and 9672-R14 which will be replaced with a z/800 0C1 in the next few months. I'm sole support for tape, dasd, OS/390 as well as TSM and, for the most part, everything runs very smoothly. Joe's problems seem to be with the structure of his organization and its charging mechanisms more than any TSM peculiarities on OS/390. For instance, I doubt that most mainframe shops IPL anywhere near as frequently as his does. Once every couple of months or even less is probably more like it. It's pretty obvious from the number of items on this list related to tape libraries and tape management in general, that this is a big problem on other platforms. Running on OS/390 you NEVER have any of those kinds of things to worry about. Sam Sheppard San Diego Data Processing Corp.

Staffing required for TSM server support of 200 clients 1, staffing for mainframe tape and dasd support 1. Actually it's just me. We are only backing up about 300gb a night but we have tuned our system to accommodate TSM and control the CPU that is consumes. As you know charge back is different from organization to organization so our charge out for CPU is kinda funny money. In any event I still feel that AIX is a better fit for our TSM environment although we have not been able to cost justify it yet, but we are still working in it. Brian L.

The tape issue turns out to be a wash for us since we'd use the same tape libs. DASD you're paying for in either case. We did the same exact eval that you're doing right now. Initially it seemed like a "no brainer". We had spare MIPS on the frame and figured, why not use them. Once we started using them, the complaints/bills started flying. Complaints due to the large amount of MIPS TSM consumes, the bill for the MIPS usage. Even though they're spare MIPS, we still get charged for them (again, internal funny money). Money aside, the staffing and maintenance schedule is enough to keep me off the mainframe. But, as always, each decision has to be based on your companies core competencies, budget and hardware availability. And finally, If I were starting from scratch, AIX implementation hands down.

We are currently running TSM 4.2.1.9 on a 9672-R44 running OS/390 2.10 and we have been doing an evaluation on moving TSM from OS/390 on to AIX. While the cost of the AIX hardware is relatively cheap we still need to incur DASD costs in the form of SAN and Tape costs, not to mention the need to develop cron jobs on AIX to handle tape processing , on OS/390 you do not have to define volumes, drives or the library to TSM. Also we found that the licensing costs of TSM itself on AIX were actually higher than the mainframe costs. Granted we are tied into tape media (STK 9840) and our management is not looking to replace that media but even if we did the cost is still slightly higher for us on AIX. Brian L.

Too many fingers in the pie (tape group, dasd group, TCPIP group, operations etc... When you begin to figure out total cost of ownership, you have to add all of these support teams into the equation, not to mention the internal charge (funny money) for MIPS usage on the mainframe that you'll incur. TSM will also be at the mercy of the mainframe IPL schedule as well, which typically is on Saturday night into Sunday morning (a window that you really want open for your large archives or db backups) If you're on any other platform, your costs should drop significantly. e.g. If you have a P690, you have 1 SA managing that server. You don't need nearly the staff that you'd require for a mainframe solution. How often does an AIX or Sun machine have to be taken down for maintenance? (not often). And finally, a P690's I/O is comparable to a mainframes. If you get the budget, go with a big Unix system. Run screaming from the mainframe solution. You'll save a lot of headaches and meetings. Just my opinion.
