This community utility is designed for the to simplify the configuration process of the Virtual SAN All-Flash configuration. As some of you may or may not know, Virtual SAN 6.0 introduces a two-tier architecture model with the all flash configuration (caching tier and a capacity tier). For which two different types of flash devices, with different endurance qualifications, are used for different purposes. Since both, tiers are composed of flash based devices, the devices that will be utilized in the capacity tier need to be marked and identified by ESXi as such.
Today, the procedure for making the capacity devices is performed from one of the two command line interface utilities which are ESXCLI and RVC. While marking the device from either of the command line utilities is a simple procedure doing that manually from the command line can become a tedious task. I arrived at the realization of this while working on my 64 node all flash cluster that I normally refer to in demos as “The BigDaddy.”
Once you start dealing with a lot of flash devices, maybe even hundreds of them, a simple utility with an extremely easy to use interface can very handy. I got together with Brian Graf and Alan Renouf (the masters of the PowerCLI automation universe and VSANChampions) and put this utility together. For the funny details on how I came up with this utility read Brian’s Post. Thanks Brian for all your handwork debugging the tool for us. Read Full Article →
