Storage Options

Compañeros! Welcome back to the SQL Trail. Have you ever wondered what a LUN is? Have you given some thought about getting more into new storage options, but aren’t sure where to start?  You’re in luck because in Episode 53 Steve Stedman and I chat with THE Argenis Fernandez, storage guru and PASS Director-at-Large. We talk storage options, LUNs, IOPs, and why he thinks we all need to approach storage a lot differently.  Steve and I learn something new from him every time we talk to him and this time is no exception.

Argenis Fernandez

Argenis is a Solutions Architect with PureStorage, a Microsoft SQL Server MVP, VMWare vExpert, and a well-known face to the #SQLFamily community, especially since he’s now the Director-at-Large of SQL PASS. He’s a regular speaker at PASS events, including SQL Server Summit. He also founded the PASS Security Virtual Chapter.

We’ve been avoiding the topic of storage for a long time. And you know what? We actually have ITIL to blame. Do you know it’s ITIL that actually started splitting responsibilities between operations and engineering? And then even within operations there will be people in charge of certain things. So isolation in environments and segmentation of duties in companies, that’s actually brought us to where we are today.
