Fault Tolerant Configurations ··· 43

Prerequisites for a Cluster

Vocera fault tolerance support requires that you set up a two-node cluster using

the Microsoft Cluster Service, a feature of the Windows Server 2003 and

Windows 2000 Advanced Server operating systems. The Cluster Service may be

implemented differently on different platforms. Refer to documentation from

your hardware and operating system vendors for complete information.

After setting up the cluster, perform the following Vocera-specific tasks:

• Set up a shared drive to maintain Vocera data. This drive must be separate

from the quorum drive.

• Create a cluster group named Vocera.

• In the Vocera cluster group, create and bring online a resource named

Vocera Data Drive to represent the shared drive. When you create this

resource, set the following properties:

• Resource type is either Physical Disk or a vendor-specific equivalent (for

example, IBM ServeRAID Logical Disk)

• Make both nodes possible owners

• No dependencies

• Specify the drive ID

• Also in the Vocera cluster group, create and bring online an IP Address

resource named Vocera Cluster IP to store the cluster’s virtual IP address.

When you create this resource, set the following properties:

• Make both nodes possible owners

• No dependencies

• IP address and subnet mask

• Network type is Cluster Public Lan

• Do not enable NetBIOS for this address
