Sudo Show 9: Storage Technologies Deep Dive

Episode 9 of the Sudo Show is a bonus episode that exists because one question during our AMA turned into way more than we expected. ComputerKid asked about SAN storage in the chat, and what followed was basically a free seminar.

We pulled that segment out and gave it its own episode because it was too good to let sit buried in a three hour AMA. The conversation covers the difference between SAN and NAS, how fiber channel and iSCSI actually present storage to a system, and then goes deep on scalable storage with Gluster and Ceph. I learned a lot just listening back to this one, especially the bit about why you want JBOD instead of hardware RAID underneath something like Gluster, since the software is already handling replication on its own.

What I liked most is how practical it gets. We’re not just talking theory, we’re talking about running Gluster on Pine64 boards in a home lab, the difference between petabyte scale Ceph and a smaller Gluster setup, and why KVM matters even if you’ve never touched it because it’s quietly running most of the public cloud.

If storage has ever felt like a black box to you, this episode does a good job cracking it open. Worth a listen.
