This section describes the Server Units SU710 and SU730 / SU730B. The SE server SE710 contains an SU710. The SE server SE730 / SE730B is equipped with an SU730 / SU730B as the first Server Unit.
Components and ports which are not used are not described below.
The SU710 / SU730 / SU730B enables BS2000 to execute on /390 architecture (in Native mode or as BS2000 guest systems).
Features
18 models with a high performance range are available. Depending on the model, one or two processor modules are used. The processor module has 8 CPUs. Depending on the model, 1 to 16 processors are available. Capacity on Demand permits temporary processor attachment.
One hot spare processor is available with dynamic activation.
The main memory is up to 256 GB in size.
The I/O system has up to 126 Fibre Channels, each with a throughput of 16 Gbit/s.
The SU supports a 1 Gbps and a 10 Gbps LAN (connection via the HNC).
The Server Unit SU710 / SU730 / SU730B consists of the following components:
a CPU box
an AROMA-P (Automatic and Remote Operation Manager) controls the power supply of the SU and occupies two height units (HUs).
two to eight channel boxes
CPU box
Depending on the configuration, the CPU box contains one or two system boards.
Each system board contains a processor chip with the following features:
depending on the model, up to eight CPU cores with a joint cache
two IOPs (I/O processors)
one MAC (Memory Access Controller)
The processor chip is connected directly to the memory of the system board.
Processors on different system boards communicate over an Inter Connect Interface.
The CPU box, together with AROMA-P, occupies six height units in the rack.
Channel box (CHE box)
Depending on the configuration level, at least two and up to eight channel boxes (#0 through #7) and up to 126 FC channels are possible in an SU710 / SU730 / SU730B. In the basic configuration, the SU710 / SU730 / SU730B has two channel boxes, channel box #0 and channel box #4.
Up to eight channel modules, each with two FC channels (16 Gbps), can be integrated into a channel box. Only in the case of the first channel box is the first slot already occupied by the system.
A channel box occupies two height units in the rack.
