SANs offer great performance in return for perceived complexity and expense. Many IT pros incorrectly equate SAN with Fibre Channel,but iSCSI offers an alternative that is widely available. Microsoft offers a software alternative (iSCSI Software Target 3.3) that has previously only been available with Windows Storage Server,but now can be downloaded from download center! In this session we describe in detail the significant performance improvements Microsoft iSCSI Software Target 3.3 offers over previous versions. We will discuss how to deploy iSCSI Boot,and show how Version 3.3 is able to support booting 500 HPC servers in under 10 minutes! The Microsoft iSCSI Software Target offers a low-cost means of supporting iSCSI booting for multiple server nodes from a single golden image,while using differencing VHDs to store only the unique data and paging for each server node.
