I don't like putting all eggs in one basket. Our site had installed AIM* on the
same box as all terminal services/thin clients and OPC services. A problem or
upgrade to one piece typically meant that all three were affected. For the WW
historian, we opted for a standalone box.
One of your questions sounds like you're more worried about the WW historian
slowing down your Galaxy functionality. I'd be more worried about big Galaxy
operations (Direct Access operations, .cab file import/export) slowing down
your ability to serve and/or record trend data.
Anecdote: Our Galaxy (EVO 9.2, CS 6.2) is also a System Auditor Alarm Shelving
Utility server, so it handles omgets/omsets for the WPs with ASU installed.
There's a scheduled task on the Galaxy that runs at 1-minute intervals to reset
an ACCUM block that alarms at 5 minutes. During nightly .cab file backups, this
alarm goes off! Conclusion: The .cab file backup is onerous enough that a
scheduled task and/or omset command can be delayed by 5+ minutes.
What might also factor into your decision - how big your site/DCS is, uptime
requirements, contingency plans for loss of historian or Galaxy programming
ability, how much history you need (ie, hard drive space), budget, etc.
Another option- virtualize physical servers and WPs on redundant V90's
(V91's?). If a basket is fault-tolerant and redundant I don't mind putting
multiple eggs in it!

Subject: [foxboro] Galaxy and Wonder ware Historian?
Guys,
I'm looking for the Pros and Cons of having both the Galaxy and the New Wonder
Ware Historian running on the same Server 2008 R2. Will the updating of tags
through inSQL Fetch cause the server to be to slow or not have enough to run
Galaxy?
EVO 9.3
CS v6.3
Wonder ware System Platform 2014
inSQL historian with 25K tags?
FoxView 10.4.4
Thanks,
Joe Scott
