Hardware features of the SX Series Business Servers
SX series business servers have the following types of partition depending on the operating
system being run on the partition:
BS2000 partition
The BS2000/OSD with the X2000 carrier system is installed. X2000 is based on Solaris
and mainly provides the runtime environment for BS2000/OSD.
Here BS2000/OSD can also run under the VM2000 virtual machine system.
The available CPUs of a BS2000 partition are divided logically into processing
processors for BS2000/OSD and I/O processors which X2000 makes available to
BS2000./OSD. The available memory is also divided between BS2000/OSD and
X2000. You will find further information in this appendix in the section on the relevant
model series.
Solaris partition
The Solaris operating system is installed.
The SX servers have at least one BS2000 partition.
The system boards (also the XSBs) of different partitions are separated from each other in
terms of the hardware.
On SX130 systems the integrated SCSI disks for booting the relevant operating system are
unambiguously assigned to the system boards concerned by plug connections. As of the
SX140 model series they are operated via integrated SCSI controllers and are assigned to
the XSBs via their slots. Each XSB has interfaces for boot disks, console, LAN, and a boot
PROM. Use of the last two XSBs of a system board always requires the presence of a
PCI/disk box.
Depending on the model and its configuration Capacity on Demand (CoD) enables the
CPUs present on the system boards but currently not in use or those present on free,
additional XSBs to be attached or detached as needed.
A description of the capability to temporarily increase the performance of the server in this
way can be found in the
"Capacity on Demand" of the manual
Functions" [1].
As far as the BS2000 addressing modes in the program address space are concerned, the
models in the SX series are fully compatible with the S servers. Data spaces are supported
on SX servers as of BS2000/OSD V6.0 and X2000 V3.0A05.
