Awesome! Thanks for the tip on the redbook

You won't be able to use a switch to expand the number of drives you would attach to a host, but you would extend the loop via the in/out ports. I would recommend checking out the IBM RedBook titled "Introduction to Storage Area Networks" and they talk about FC topology starting on page 90 (it's freely available as a PDF or even as an ePub file).

Linh Pham

The idea of dual-attached SAS drives comes from the dual-loop FC drives as a form of redundancy. It allows you to have redundant paths from a host to the drives (think of two different FC HBAs, in case one goes kaput or the fiber connection drops out), or you have a pair of hosts where you can split the drives across hosts or one host owns all the drives while you have passive that can take over.

Ahh interesting! So both machines can be on the loop. This will be fun haha

FC drives use the small SCA connectors since they only need to provide power and a handful of pins required for dual FC loops. The drives and the drawers will connect to the server as arbitrated loops. It's been a while since I've worked with FC, so I don't remember the x_Port terminology used. 😅

haha I love it. yeah that's not a bad idea!

Loved the remodel update! For the smaller videos maybe the ITWatchDogs environment monitor would be a good one. I say that because I got mine in the mail last week and I'm ready to follow along hahaha!
