NFS Best Practices – Part 3: Interoperability Considerations

Welcome to part 3 of the NFS Best Practices series of posts. While part 1 looked at networking and part 2 looked at configuration options, this next post will look at interoperability with vSphere features. We are primarily interested in features which are in some way related to storage, and NFS storage in particular. While many of my regular readers will be well versed in most of these technologies, I’m hoping there will still be some items of interest. Most of the interoperability features are tried and tested with NFS, but I will try to highlight areas that might be…

NFS Best Practices – Part 2: Advanced Settings

Following on from part 1 of the NFS Best Practices, part 2 is going to look at tuning from a vSphere perspective. As mentioned, our objective is to update the NFS Best Practice white paper which is now rather dated. There are quite a number of tunable parameters which are available to you when using NFS datastores. Before we drill into these advanced settings in a bit more detail, it is important to understand that the recommended values for some of these settings may (and probably will) vary from storage array vendor to storage array vendor. My objective is to…

NFS Best Practices – Part 1: Networking

There is a project currently underway here at VMware to update the current Best Practices for running VMware vSphere on Network Attached Storage. The current paper is a number of years old now, and we are looking to bring it up to date. There are a number of different sections that need to be covered, but we decided to start with networking, as getting your networking infrastructure correct will play a crucial part in your NAS performance and availability obviously.

Heads Up! VSA Manager 5.1.x – Install Error 2896: Executing action failed

I was asked recently to provide some assistance with a VSA installation problem. The issue which this person experienced is described in the release notes for VSA 5.1.1 . VSA 5.1.1 installation fails with the Error 2896: Executing action failed message This problem might occur when the location of the temp drive is set to a drive other than C:, where VSA Manager is to be installed. Workaround: Make sure that the user and system TEMP and TMP variables point to a specified location on the C: drive.
