290 DS8000 Series: Concepts and Architecture
13.2.9 Migration considerations
A DS8000 will be supported as an IBM 2105 for z/OS systems without the DFSMS and z/OS
SPE installed. This will allow customers to
roll the SPE to each system in a sysplex without
having to take a sysplex-wide outage. An IPL will have to be taken to activate the DFSMS and
z/OS portions of this support.
13.2.10 Coexistence considerations
Support for the DS8000 running in 2105 mode on systems without this SPE installed will be
provided. It will consist of the recognition of the DS8000 real control unit type and device
codes when it runs in 2105 emulation on these down-level systems.
Input/Output definition files (IODF) created by HCD may be shared on systems that do not
have this SPE installed. Additionally, existing IODF files that define IBM 2105 control unit
records for a 2107 subsystem should be able to be used as long as 16 or fewer logical
subsystems are configured in the DS8000.
13.3 z/VM enhancements
z/VM is an IBM operating system that supplies a virtual machine to each logged-on user. The
DS8000 will be supported on z/VM 4.4 and higher.

13.4 z/VSE enhancements
z/VSE is a system that consists of a basic operating system (VSE/Advanced Functions) and
any IBM-supplied and user-written programs required to meet the data processing needs of a
user. VSE and the hardware that it controls form a complete computing system. The DS8000
will be supported on:
z/VSE 3.1 and higher
VSE/ESA 2.7 and higher

VSE/ESA does not support 64K LVS for the DS8000.
