7 Using ESAM in a cluster system
There are specific software and configuration requirements for using ESAM in a cluster system.
Cluster system architecture
The following diagram shows the architecture of a typical implementation of a cluster system.
You connect an executing node and a standby node to MCU and RCU so that the nodes can
access both MCU and RCU. A heartbeat network must be set up between the nodes.
If a failure occur in the executing node, operations are continued by a failover to the standby node.
Required software
The following software is required to use ESAM in a cluster system:
•
Software that uses a SCSI-2 Reservation with the hypervisor platform, Virtual Machine File
System 5 (VMFS 5).
•
Cluster software.
Supported cluster software
ESAM supports the following types of cluster software:
Operating systems Software
Microsoft Failover Cluster (MSFC) •
Windows Server® 2008
• Windows Server® 2008 R2
AIX 6.1 TL6 PowerHA (HACMP) 5.4.1 SP7
