Sysman
Old Geek <:)=
11:00 PM on a Friday night, and what is Sysman doing? 
3 years ago, we got a nice new project from one of our best customers. It was a tough time for the company. We had just lost another big client, and had to lay off 20% of the staff. The new project really was a huge part of our future...
It took us more than a year to write/modify the programs, almost another year to "debug" it in a real world production environment. But we finally "went live" on April 1 this year...
We have a pretty nice mainframe at work. An IBM z/800 with 3 CPUs, 16 fibre channels, 8 of which talk to the disk array. A couple more channels feed the "OSA" adapters, which are the interface to the web, and our local LAN. A couple more run the tape drives, etc...
Before we "went live" we had about 150 on-line users. Plus a fair amount of "batch work", like customer service people doing custom reports, us programmers doing compiles and tests...
But since we "went live" we now have about 250 on-line users. And the amount of batch work has also increased a fair amount. It is starting to "stress" the system...
So I just ordered a 4th z/800 CPU, another OSA adapter to keep up with the increased web traffic, another disk array, and another 8 fibre channels to drive the array. We do have plenty of space on the first array, but being able the "split the load" on another set of channels, another set of access arms, etc., should provide a giant overall performance improvement...
The boss just said yes, I just called my IBM dude and said yes...
So have a beer, and help me celebrate! Life is good!!!
