Active\Active Support in Windows 2000 Adv Server using MSCS on Compaq DL380 G3 Packaged Cluster ?

I have DL380 G3 Packaged Cluster running Windows 2000 Advanced server and MS Cluster Services.

Want to use Node 1 for SQL DB and Node 2 for Application (COM+) with Node 2 being failover for SQL DB and Node 1 for Application - apparently this is deemed "Active/Active" (?)even though we do not intend to run 2 copies of either at same time.

Compaq support this config for active/active but I have heard on grapevine that Microsoft (using MSCS as built into Win2k Adv Server) do not (Active\Passive only)...problem is I can't find anything on website to see official statement to that effect.

More specifically, I need to know:-

1. Does Microsoft support Active\Active using MS Cluster Services on Compaq DL380 G3 Packages Cluster ?
2. Does Compaq/HP support Active\Active using MS Cluster Services on Compaq DL380 G3 Packages Cluster ?

this setup is considered active/active because both nodes are running applications that have the ability to failover to one another

Answers to your questions, being a former Compaq/HP Consultant:

I am running about 12 A/A Clusters Compaq/HP Proliant and some of them are packaged clusters.
Make 100% sure you are running the latest ROMPAQ on all your devices, we lost an exchange DB because we were at a low patch level.


For SQL - WE setup a Single default instance on the 1st cluster and use the shared drives for the data, and then setup a named instance on the second node.

I'm going to accept these answers anyway but just want to clarify some issues (I'll add more point to question before accepting to make it fair...or use a dummy question to allocate points if EE doesn't allow points modify to question):-

1. For SQL cluster:-

a. Billy suggests separate SQL instance on 2nd this necessary/pre-requistite ?
b. Do you need a separate db and/or disk resource for 2nd node instance ? (if yes then how do you synchronise ?)

2. For COM+/SQL:-

a. I have seen some (vague) references to needing separate disk physical resource for differing apps (e.g. 1 x RAID-1 pair on shared for SQL (or 2 x RAID-1 pair if ans to 1a is yes) and 1 x RAID-1 pair for COM+ - can anyone elaborate/confim/deny ?
b. I have seen article about COM+ Clustering but it seemed to indicate use of Network Load Balancing rather than clustering - can you use either for COM+ ?
c. Following on from the above, we may want to use simple Active/Passive for SQL and NLB for COM+ - is it acceptable to mix and match these technologies on the same servers ?

3. Deployment

a. Have used PQ Deploy Center in the past (and Ghost a little bit) to deploy mainly PCs - although have used for servers - what is best way/best practice to deploy several clusters (each on different domain) ? Options as I see them:-

i) Just image of plain OS and manually do rest
ii) Image of servers after cluster service installed/configured (not sure of issue this will present upon restore of image)
iii) Image of servers after cluster service AND applications installed/configured

...more options ?

Please comment.
