7.5 IBM iSCSI Server Adapter in Microsoft Cluster
Server
This section describes the installation of a Microsoft Cluster Server with two
nodes and shared storage from a IBM TotalStorage DS300. Each cluster node is
equipped with two IBM iSCSI Server adapter. This two adapter are currently not
used for host bus adapter failover. The logical drives are accessed over one host
bus adapter or the other but not both.
For security not only the HBA has to authenticate with CHAP on the TotalStorage
DS300 but also the TotalStorage DS300 has to authenticate against the
initatiors.This is called bidirectional authentication.
Microsoft Windows Server 2003 Enterprise Editions is used as operating system
because this includes the cluster service.
7.5.1 Planning and considerations
The nodes will be equipped with two iSCSI server adapters. This permits the
ability to distribute the load over two adapters. When a host bus adapter failover
driver becomes available, it can be installed and the assignment of the logical
