Preface
X2000 is based on the Solaris operating system and provides the following functions:
HAL (Hardware Abstraction Layer)
HAL maps the hardware-software interfaces of the /390 mode to equivalent interfaces
of the SPARC64 mode.
/390 firmware
The /390 firmware component extends the SPARC64 mode and enables existing
customer applications to run object-compatibly on the SX servers under OSD/XC. This
applies both for applications generated with ASSEMBH and also for programs which
were generated with the BS2000 compilers for high-level programming languages. As
of OSD/XC V2.0 and X2000 V3.0A05 the SX servers also support ESA data spaces in
customer applications. Objects which are available in the special RISC object format for
SR2000 must be recompiled. The commands supported by ASSEMBH are described
in the manual
Execution of the inputs/outputs and data communication
Administration and operation of the SX server
Entry-level models in the SX series
The entry-level models in the SX series are non-partitionable and designed for use exclu-
sively with the BS2000/OSD operating system. BS2000/OSD running on entry-level models
uses the functionality of the X2000 carrier system.
With these models, too, state-of-the-art processor technology, the efficient LTO tape device,
and optional fibre channel connection technology for FibreCAT and Symmetrix disk systems
and for CentricStor and ITC/SBU with SAN integration capability make these servers a
future-safe investment.
You will find more detailed information on the hardware of the different model series in the
