Installing SAP Mobile Platform with a Microsoft Failover Cluster with Shared Hosts

This installation scenario locates two data tiers on separate servers within a Microsoft Failover Cluster, and two SAP Mobile Server Application Server nodes are colocated on the same servers, one with each data tier, but outside the failover cluster. This provides failover capability for the data tier servers and load balancing between the SAP Mobile Server instances on minimal hardware.

Prerequisites

The architecture, design characteristics, and use cases for this installation scenario are described in Landscape Design and Integration > Designing the Landscape > Microsoft Failover Cluster with Shared Hosts. The installation instructions in this chapter assume that you have used the Landscape Design and Integration document to design the landscape

This diagram illustrates the system you are installing with this scenario:


Microsoft Failover Cluster on shared hosts
Note: You cannot install cluster nodes concurrently. You must perform Microsoft Failover Cluster tasks and install the nodes in this cluster in this order:
  1. Perform critical Microsoft Failover Cluster setup tasks.
  2. Install the first data tier.
  3. Prepare Microsoft Failover Cluster for second data tier.
  4. Install the second data tier.
  5. Install the first SAP Mobile Server as an application server node.
  6. Install the second SAP Mobile Server as an application server node.
Task
  1. Critical Prerequisite Tasks
    Perform all critical tasks before you attempt to install the first data tier in your Microsoft Failover Cluster environment.
  2. Installing the First Data Tier
    Install the first of two data tiers on a server that is the active node in a Microsoft Failover Cluster.
  3. Preparing Microsoft Failover Cluster for Second Data Tier Installation
    With the first data tier installed, in preparation for installing the second data tier, complete the configuration of the failover cluster to handle all the tasks involved in switching the two data tier nodes between active and passive states.
  4. Installing the Second Data Tier
    Install the second of two data tiers on the second server in the Microsoft Failover Cluster where the first data tier is installed.
  5. Installing the First SAP Mobile Server Node
    Install the first SAP Mobile Server as an application server node outside of the Microsoft Failover Cluster. Initially this is the primary SAP Mobile Server node for the cluster.
  6. Installing the Second SAP Mobile Server Node
    Install the second SAP Mobile Server as an application server node outside of the Microsoft Failover Cluster. Initially this is the secondary SAP Mobile Server node for the cluster.
  7. Verifying the Full SAP Mobile Platform Cluster Installation
    Verify that you can see all SAP Mobile Server nodes in the cluster in SAP Control Center, and that you can inspect the settings for each.
