CUCM on UCS - C w/CCx, ER, ELM, 281 Users

Experts

I am working on a single site with 281 sets (50 of them CCx sets) and I need ER for a remote building in campus, plus ELM for easy license management.

This is a net new deployment, with a Cisco 2921 Router - PSTN Gateway with SRST, Catalyst 3750 routers and CUCS - C Class (2 servers for redundancy)

I would like to have the PUB and SUB 1 on Server 1 with Unity Connection 1 & SUB 2 and 3 with Unity Connection on Server 2 for complete redundancy. (Any recommendations here)

My questions are, since I used CUWL STD bundled do I need to separately add CUSS or that is included on the CUWL.

I added CCx licenses separately, do I need to show the CCx application separately on the server diagram below to assign CPU cores to it, and how many cores?

I am also in doubt about the steps to add the 3 SUBs licenses to my 9.0 Publisher Cluster, my intention is to use 2 UCS - C Servers for redundancy with the application distribution showing below.

I attached the report showing the BOM for details, I thank you all for the recommendations.

A four-node cluster rarely makes sense. Look at the SRND for guidence here but for <1200 users/devices you typically only need two nodes. If you have exceeded that you are at a five-node cluster, not four.

UCSS is a required subordinate SKU and must be selected when building the order. Validation will flag this as a problem in either Netformx or CCW if you try to skip it. Also note the CUWL UCSS only covers the products included in CUWL-STD (i.e. not CCX or CER).

Yes. This depends on the OVA you choose.

Also, be advised of the following tools:
