"SB111" does indeed match the pattern. You want /^SB[0-9]{1,2}\z/i.

Then there's the issue that you use $& when no match occur, even though it's only set on match. I think you use !~ when you meant to use =~.

Then there's the issue that you use $&, which causes all non-capturing regex matches in your program to become slower. $sbNumHost1 would be a suitable replacement for $& here.
