Windows Server 2003 iSCSI Cluster Supports

Windows Server 2003 iSCSI Clustering Consulting Services

Windows Server 2003 supports an iSCSI Cluster supports on 2 nodes using SCSIport, Storport and MS Software Initiator. Coincident with Windows Server 2003 Service Pack 1 (SP1) release the iSCSI support we intend to change the requirements so that 2 nodes are supported under the SCSIport storage stack and 8 nodes under the Storport and MS Software Initiator stacks. This is crucial in clusters which have more than 2 nodes. SCSIport does not support individual LUN resets, therefore we are limiting SCSIport support to two nodes. Individual LUN reset is very important in scenarios in which you have multi-node clusters in which disk failovers need to happen with as little disruption as possible other disks unaffected by the failover.
