Best Practices for File System Alignment in Virtual Environments
This paper provides guidelines for preventing, detecting, and correcting file system misalignment issues for virtual machines hosted on VMware ESX, Microsoft Hyper-V, and Citrix XenServer infrastructures. File system misalignment is a known issue in virtual environments and can cause performance issues for VMs. The steps outlined in this paper should be taken so that the issue can be prevented during the storage provisioning and VM creation phase of the project. For existing VMs, the steps outlined in this paper should be taken to detect and correct any existing misalignment issues. Please note that this issue is not unique to NetApp storage and can occur with any storage array.
