Appendix
The basic versions of the additional BS2000 partition have the same performance classifi-
cation as that of the first BS2000 partition. They are equipped with a model-specific number
of processors, a model-specific memory capacity, 2 boot disks, power supply and fans so
that they can be installed in the system cabinet in addition to the first BS2000/OSD
instance.
The customer defines which XSBs are included in further partitions.
Servers can be upgraded by adding CPUs. An SX140, for example, can be upgraded to
model SX140-60C by adding a total of 7 used CPUs.
Models can be easily upgraded on site.
Important system components, such as hard disks, power packs and fans, are designed
redundantly and can be changed during live operation. The maximum power supply
protection can be achieved by using the optional dual power supply.
The SX140 system has a highly available system control network; this has the following
functions:
– It monitors and controls the operating status (temperature, fans, etc.).
– Defective memory blocks are handled without any effect on the system.
– It informs the console about error conditions.
– It forms the basis for preventive maintenance.
– It monitors and controls all cabinets via RCI (Remote Cabinet Interface).
Peripherals of the SX140 system
Channel peripherals (of type 2 and type S) can be connected to the SX140 server by a
maximum of 2 channel chassis in a BS2000 partition. A maximum of 32 channels in total
are therefore available on an SX140 in a BS2000 partition. Any combination of channels of
type 2 and type S is possible.
The channel subsystems are built into the rack of the SX server.
Each system board has 2 onboard-integrated SCSI controllers for connecting the hard disks
and 2 onboard-integrated Ethernet controllers.
In the basic version, two disks (each of 72 GB) are assigned to the (first) BS2000 partition.
Optionally a FibreCAT or Symmetrix disk storage system can be connected via Fibre
Channel
CentricStor and ITC/SBU can also be connected via Fibre Channel.
