What happens in linux when you have more than 26 drives?
In linux you have your drives, /dev/sda etc.
Logically, the 26th would be /dev/sdz, but what happens after that?

Double letters, maybe? Numbers, like /dev/sda1?
/dev/sda1 means the first partition on sda
You send the 27th and so forth my way.
I have no clue really, i would think it would add a second letter /dev/sdaa or something to that effect. The better question would be why do you have 26 drives?
I don’t. I just was wondering what would happen since I was formatting a few drives today.
^Do you have any idea what they’re talking about?
This will depend on the version of Linux you’re running; device files in /dev are often created automatically by the kernel and the number and naming scheme will vary. In RHEL and some IBM bullshit, this is entirely kernelspace (devfs?) and in 2.6.15+, this is mostly userspace (udev).
For example, *BSD and its cousin, Mac OS X, create device files in the /dev/diskxsx style: disk1s1 is the first partition of the first disk, etc.
Anyways, to answer the damn question, often there will be two letters added: /dev/sdaa1, /dev/sdab1. This happens on RHEL and SUSE, according to this authoritative-looking IBM handbook.
Don’t put complete faith in any of this—it seems like this is very possibly something that varies across architectures/drivers/distros/whatever.
