SAP Gateway, Workmanager and SMP 3 relationship

Hi Everyone,

I'm trying to setup SAP mobile platform(SMP 3.0) for our company and deploy SAP WorkManager. After going through SMP documentation I believe this is the setup that is needed:

SAP Business               SAP Gateway                                             SMP 3.0 cluster

Suit Backend    <---->    (Formerly Netweaver Gateway)   <---->  (comes with embedded integration  <---->  Mobile devices(WorkManager APP)

                                                                                                                   gateway)

SAP Gateway(formerly netweaver gateway) exposes backend data through OData protocol, SMP 3.0 cluster which consists of data tier cluster(2 Oracle DB servers) and application cluster(2 SMP 3 servers) provisions that OData channels. Workmanager is deployed on SMP 3.0. Now I have these questions:

1- Is this a correct setup?

2- Workmanager is a Syclo Agentry APP so do I need to put that SAP Gateway there?

3- Considering that Workmanager is Syclo APP, Does it use embedded integration gateway inside SMP 3.0?

4- If question 3 answer is Yes, and considering integration gateway can not be clustered, what would be my alternative clustering(HA) solution?

Any help would be highly appreciated.

Thanks
