The BT Global Update diagnostics table is organized by rack, I/O group
(Grp), and slot (Slt). The first row (0:) shows the BTRs first, then the BTWs
on rack 0. From left to right, BTRs at I/O group 0, slot 0; I/O group 0, slot 1;
I/O group 1, slot 0; I/O group 1, slot 1; and so on.
A lower case ‘r’ or ‘w’ indicates that a block transfer has been observed at that
location at some point in the past. An upper case ‘R’ or ‘W’ indicates when a
block transfer happens.
