The following direct access storage devices and control units are
supported by VM/370. The direct access storage devices sUpported by VM/370 are: ,. IBM 2305 Fixed Head Storage, Models 1 and 2. , IBM 2314 Direct Access Storage Facility. IBM 2319 Disk storage. IBM 3330 Disk Storage, Models 1, 2, and 11. IBM 3333 Disk Storage and Control, Models 1 and 11. IBM 3340 Direct Access Storage Facility, Models A2, B1, and B2; the 3348 Data 35, 70, and 7Cr; and the 3344 Direct Acc€sz Storage, Model B2. IBM 3350 Direct Access Storage, Models A2 and B2.
All of these direct access devices are supported as VM/370 system
residence, paging and spooling devices and as virtual devices for use by
virtual machines. All are supported as dedicated devices. All except
the 2305 are supported by CMS. The following direct access control units are supported by VM/370: IBM 3345 Storage and Control Frame Models 3, 4, and 5 on the Models
145, 145-3, and 148 with the standard ISC for: --3330 Models 1 and 2
--3333 Models 1 and 11 --3340 Model A2 and 3344 Model B2 --3350 Model A2 IBM 2835 Storage Control Model 1 for 2305 Model 1. IBM 2835 Storage Control Model 2 for 2305 Model 2. IBM 2844 Auxiliary Storage Control for 2314 and 2319. IBM 3830 Storage Control Model 1 for 3330 Models 1 and 2 only. IBM 3830 Storage Control Model 2 for 3333 Models 1 and 11 , 3340 Model A2, and 3350 Model A2. IBM 3830 Storage Control Model 3 for 3330 Models 1 and 11, and 3333
Models 1 and 11. IBM 3880 Storage Control Model 1 for 3330 Models 1, 2, and 11, 3333
Models 1 and 11, and 3350 Models A2 and A2F. IBM Integrated File Adapter (#4650) on System/370 Models 135 and 145

IBM 3350 Disk Storage, Model 12. .!ith 3350 Expanded Control Store special feature (12151) provides additional
control storage for microprogramming use and is a prerequisite for 3350 disks attached to the 3830 Model 2; or for the 3345 Integrated storage
control units Models 3, 4, and 5 attached to a System/370 Model 145,
145-3, 148, 158 or 168.
The Control Store Extension feature (#2150) is a prerequisite for
feature 12151. Notes: IBM 3330 Model 11 can be used as a system generation device in the same way as the 3330 Models 1 and 2, since the starter system
does not use cylinders 404-807. 2. The System/370 Models 145, 145-3, and 148 must have the Word Buffer
feature (#8810) installed in order to attach a 3330, 3340, 3350 or 2305 Model 2. Part 1. Planning for System Generation 109
