The SAN Guy

Welcome to The SAN Guy blog! Thank you for reading my posts and for supporting my site, I appreciate all of the comments and positive feedback I’ve received over the years. A new addition to my blog is the ability for guests to submit posts for publishing. I’ve received many comments and emails over the years with some great ideas and content, so I wanted to give the opportunity to my readers to submit related content that may be useful to the storage community in general.

Below is a list of all of the posts and articles I’ve written over the years, grouped by general category.

Scripting (Automation and Reporting). Over the years I’ve created a ton of windows and UNIX scripts to automate tasks and create custom reports, most of which I’ve created blog posts about. Below is a list of all of my posts that include custom scripts that I’ve written.
