VMware has released a White Paper titled “Recommendations For Aligning VMFS Partitions”. The White Paper provides decision makers the information on partition alignment, a known issue in physical file systems, and its remedy. The goal of the testing reported in this paper was to validate the assumption that unaligned partitions also impose a penalty when the partition is a VMware Virtual Machine File System (VMware VMFS) partition.
This paper lists a summary of the results of our testing, recommendations for VMware VMFS partition alignment, and the steps needed to create aligned VMware VMFS partitions. It covers the following topics:
• Executive Summary on page 1
• Recommendations on page 2
• Instructions for VMware VMFS Partition Alignment Using fdisk on page 2
• Instructions for Guest File System Alignment on page 3
• Caveats on page 5
• Background on page 5
