8 FBA pages make up a "track" in full track cache. With CKD it is known
that if one page is referenced on a track, it is likely that others on
that track will be referenced. This information is not known for FBA.
Therefore we wanted to keep the number of pages per FBA track small.

"track". MDC does not use blocks
per cyclical group since a track
would not necessarily be
page-aligned.

in an FBA "track".
