MOSS plus Project Server 2007 middle tier
Posted on 2007-10-10
I need some reference information and a few questions answered regarding an installation of MOSS + Project Server 2007. I've not installed Project Server with MOSS -- but I also want to be sure I've read the correct TechNet materials. Some related things seem a little contradictory as well.
Please set me straight here.
The current topology is a medium to large farm, 8 servers with a planned configuration as follows:
a) 2 WFE's in an NLB (hardware load balanced)
b) 4 middle tier application servers (1 index server, 1 Query, 2 servers TBD )
c) 2 SQL Servers (clustered - Active/Passive) with Analysis and Reporting Services installed
Pretty standard stuff I think - Here are my questions
1) I understand that index server needs to be a single server. What should I suggest as a recovery plan if the index server dies? Any way to make this redundant? What is the current industry suggestion here?
2) TechNet says that project server MUST be installed on each farm server. This means the installer must be run on all six servers (excluding SQL). If so, would there ever be a reason to have Project Services run in its own NLB (say with 2 of the 4 servers) in the middle tier?
Multiple middle tier servers can run the same services (example: Excel services) but I don't see in that same material saying that two or more middle tier servers need to be load balanced. Yet, another document/book may show a diagram of each middle tier server being load balanced.
So my basic question is under what circumstances is NLB sggested (for redundancy/availability) in the middle tier or is joining the farm during install enough for any application within a MOSS environment? - Particularly with Project Server 2007.
