Deploying iSCSI Boot Nodes in a Windows HPC Cluster

Applies To: Microsoft HPC Pack 2008 R2, Microsoft HPC Pack 2012, Microsoft HPC Pack 2012 R2, Windows HPC Server 2008 R2

Starting in Microsoft® HPC Pack 2008 R2, you can centralize the storage of boot images of your HPC cluster compute nodes by using iSCSI storage arrays. An iSCSI storage array is a computer, storage system, or appliance that provides storage resources over a network connection, using the iSCSI protocol.

By using iSCSI storage arrays, the compute nodes in your cluster do not require a local hard disk drive to serve as a system disk. Instead, the nodes can use the storage resources on the storage arrays to boot a Windows operating system running HPC Pack over the network. Compute nodes that use the storage resources on the storage array to boot over iSCSI are called iSCSI boot nodes.

This guide provides step-by-step procedures for deploying iSCSI boot nodes in your HPC cluster.


To deploy iSCSI boot nodes in a cluster that is running HPC Pack 2012, ensure that the cluster is updated with at least Service Pack 1 (SP1).
