I know that everyone has a different opinion on how things should be done.
I am open to hearing what others have done and reasons why we should do a certain set-up or a better approach.
Currently we have CUCM 6.1 running on 7845 H2 servers. Currently we only have a Publisher and Subscriber. We also only have about 100 users at this time configured.
2 Corporate Offices
-Location one 400 Users
-Location two 100 Users
-Ranging from 5 to 10 Users
-Location one 100 Users
-Location two 20 Users
-Location three 15 Users
-Location four 13 Users
-Currently 2 locations in Mexico
--Location 1 50 Users
--Location 2 100 Users
-Approximately 300 Users
The design approach "WAS" Separate clusters for each entity.
1. Retail, which would cover Stores and Warehouses
2. Corporate Office One
3. Corporate Office Two
I am not 100% sold on doing this. My thought was have 2 Clusters, one in each Corporate Office and build sites off of those. Each cluster can handle upto 30,000 phones so why not? Unless there is another reason not too.
I believe we have money allocated for 3 total cluster.
Is this the best approach?
Right now we only deliver dial-tone and want to add features.
Need mobile user access
Need extension mobility*
Need Conference Calling
Need Contact Center*
*I understand that these are separate servers already.
Money is not an issue at this point, it is more of a best approach issue, what is the best?
Since the international locations are only in Mexico I would go with a single cluster for all sites, unless there is a policitcal reason not to.
Another driver would be the contact center, how many agents do you envision as that can drive the totoal supported phones down to 2000 phones with UCCE 7.2 and below or 4000 with UCCE 7.5 according to latest marketing slides. So if you envision significant contact cetner I would split the environment into 2 clusters.
