Tom: I've been in the IT field for a very long time. When I started punch cards had round holes and 90 columns. While the punch cards have gone the way of the dinosaurs some things have not. One of those that has not disappeared over the decades is the failure to look at Total Cost of Ownership (TOC) when contemplating a platform switch. The failure to look at TOC has bitten more than one MIS manager in a certain part of their anatomy. For example: * The Windows world is very much a flat earth model - each app runs on its own server. Where you have one server now, there will be 10's of servers tomorrow. By the way, good heavy duty Intel based machines don't come cheap, even from Dell. * Check the uptime statistics for Windows servers. Gartner and others can provide the numbers. The last I heard the stat was at about 98.5 percent. Assuming a 24 hour a day, 5 days a week operation, month in and month out means you are down just short of 30 hours per month on each server. To provide for this level of outage sites generally set a duplicate server in place on critical applications. Oh yes, this up/down time stat is the reason why IPL-ing a Windows box is no big deal - Windows sys admins do it all the time. When was the last time you IPL-ed your AS400? And it's not the hardware. I have clients running UNIX on the same hardware who go 1 to 2 years between IPL events. * Check the staffing levels of Intel architecture sites. In my experience they generally carry twice the staff found at an AS400 site. * Do not forget Windows does not come with the DB engine. Whether it's Oracle or SQL server or MySQL or Progress or DB2 there is an extra cost to license the DB stuff for each server. * What do you plan to do about the language "barrier"? Frankly, RPG is a dirty word in the Windows world. And while C++, java, SQL, etc. are all capable languages they all require training and ramp up time - read more money. * And the biggest hurtle of all: the conversion of your business to the new platform will cost 3 times as much as budgeted and take twice as long as planned. When management looks at the TOC I suspect they will determine the risk/reward ratio simply does not support the change. Yes, lots of sites take on the challenge; that's where the "cost 3 times as much as planned and take twice as long as allowed" comes from. It's also why the IT manager's door in a few shops is a revolving door.

As we continue to hang more and more bolt-ons to BPCS we are being forced to upgrade platforms. We are looking at a AS400 810 with 1492 CPW and no interactive limits. This is quite expensive and our IT director is not a real IBM fan and has asked me to find out more about the Windows 2000 server capabilities. We have a 130 BPCS license count. Has anyone had experience with the SSA product on the supposedly supported windows platform? I am sceptical on how we could even size a Intel platform large enough to support our already overloaded system. - Tom ____________________ _______________________________________________ This is the SSA's BPCS ERP System (BPCS-L) mailing list To post a message email: BPCS-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/bpcs-l or email: BPCS-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/bpcs-l.
