This section describes the Server Unit SU500. SE500 is equipped with an SU500 as the first Server Unit.
Components and ports which are not used are not described below.
The SU500 enables BS2000 to execute (in Native mode or on BS2000 VMs) on /390 architecture.
Features
6 models with a high performance range are available. The processor module has 8 CPUs. Depending on the model, 1 to 3 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 64 GB in size.
The I/O system has up to 94 Fibre Channels, each with a throughput of 8 Gbit/s.
The SU supports a 10 Gbps LAN (connection via the HNC).
The Server Unit SU500 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 six channel boxes
CPU box
The CPU box contains one system board.
The system board contains a processor chip with the following features:
four CPU cores with a joint cache
two IOPs (I/O processors)
one Mac (Memory Access Controller)
The CPU box, together with AROMA-P, occupies six height units (HUs) in the rack.
Channel box (CHE box)
Depending on the configuration level, up to six channel boxes (#0 through #5) are possible. In the basic configuration, the SU500 has two channel boxes, channel box #0 and channel box #4.
Up to eight channel modules, each with two FC channels (8 Gbit/s), can be integrated into a channel box. Only in the case of the first channel box is the first slot already occupied on the system side.
A channel box occupies two height units (HUs) in the rack.
