Bruce Mackenzie-Low examines the benefits and disadvantages of MBR and GPT-based Windows disks. The 2 approaches differ in how they track the mapping of physical disk sectors to logical block numbers. MBR (Master Boot Record) is widely accepted, but partition size is limited to 2 terabytes. GPT (GUID Partition Table) was created to accommodate the larger partition sizes and offers greater resilience to corruption.

Windows failover clusters can now take advantage of iSCSI storage to access shared data. Using iSCSI reduces the initial investment costs for clusters by allowing you to use your existing TCP/IP networks instead of expensive SANs. This article by Bruce Mackenzie-Low explains how to set up iSCSI-based disks and configure them for use with Windows failover clusters.

How to use the Cluster Validation Wizard, also known as Validate, to perform a variety of tests to ensure that cluster components are accurately configured and supported in a clustered environment. Bruce Mackenzie-Low explains using the Cluster Validation Wizard to systematically test the storage subsystem in order to isolate any failing components, including generation of a Validation Report which documents the tests and their results, along with hyperlinks to detailed troubleshooting information such as failing disks and server names.
