Many of the customers I talk to have a fixation on port numbers. I find it a bit unusual because we tend not to have the same sort of fixation on anything else we do in life. The benefits of more ports seem obvious—my fellow blogger Dave Berry writes about how performance and capacity help data centers do more with less—but when it comes to RAID controllers or HBAs, we definitely have a fixation.
For example: I have 2 x SSD – hmm, you don’t have a 2-port controller so I’ll look at 4-port instead. I’m not interested in looking at 16-port controllers because I’m fixated on the number of drives I currently have. That’s a shame because in fact it’s the 16-port controller that you need, whether you currently realize it or not.
