The Teradata database-engine racks had large arrays of disks and high densities of CPU's. Not sole 11/84's.
If you had a standalone short rack with a 11/84, I think that was used as front-end communications, RJE-style, to the IBM mainframe it attached to. I recall many vendors put a DEC bisync card in a Unibus 11/44 or 11/84 chassis and effectively emulated RJE. This may have been the Teradata "IFP", but it could also have been some other third-party bolt-on not directly sold by Teradata related to other RJE stuff in the shop. If I had to guess based on my experience: at least half of all 11/44's and 11/84's sold were equipped with bisync cards and used in a variety RJE front-ends.
