Subject: What is a good SCSI tags value?

I noticed (though LINT and ncrcontrol) that I can set the number of
tags used. I have a NCR board and used to have the FAILSAFE option
set. This reduces SCSI_NCR_DFLT_TAGS to 0.

One of my 3 disks seems to support tags. Now I wonder:

- What exactly are these tags? I think it is something like number of
  concurrent disk operations, is that correct?

- I can set it to 16, maximum. What is a good value?
