In my Experience, I have used Multiple flavors of Unix and Window, and I prefer windows, I'm just not a Unix guy. I am not answering your questions just giving you more to think about, and if you have taken all of this into consideration great, if not here you go.
First and foremost you need to review the Compatibility Matrix on the Remedy Support web site Then I would look at the Getting Started guide and the Concepts guide More questions have to be asked about sizing; What type of application or applications are you going to run, Issue Tracking, Change Management, Asset, etc? Will these be Off the Shelf Remedy apps or Custom built? Though you are only talking about 25 write licenses, will you allow Read licenses to create and modify? You will need to have some Idea of how many records per a given time frame will be created, and how much data is on each record, in other words How many records and how many columns per record. One of our environments is a Windows server with 4 processors and 4 gig of ram and at peak we can have up to 2000 + concurrent users using 4 separate Issue Tracking apps. That is a clustered App server only with a separate MSSQL DB Cluster of the same size, and performance has never been a real problem. Performance is obviously related to two things, the Server and the Network. The network is on you to research, the server in my opinion Bigger is always better. ARS is a Memory hog and has the tendency to have memory leaks, again the more the better. I would get the most server your management and budget will allow, think scalability. Server questions you need to ask yourself Are you going to maintain the Database locally or on a separate server? Is the Server completely dedicated to ARS (always recommended) or will it house other apps? How many outside integrations to other apps will you have? Load Balancing; Never a bad Idea, but why with 25 users, unless you have more concurrent users with read licenses, and if they submit or not. Mid-Tier, I prefer a separate web server, but again how many concurrent users? -- Gary Dries _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org ARSlist:"Where the Answers Are"
