Operating Systems, Modular Expansion, System Partitioning

Operating Systems

dual inline memory module (DIMM) sockets that support 2-GB or 4-GB fully buffered DIMMs, and all the other components it needs to function as a self-contained computer system.

Modular Expansion

The cell-based building-block design allows Express5800/A1160 systems to grow as business needs evolve. By connecting cells together, you can expand an Express5800 Model 7600R system from 4 to 16 processor sockets. Memory expands from 2 to 128 DIMM sockets. With 4-GB fully buffered DIMMs, a cell can contain up to 128 GB of memory, and a 4-cell system can contain up to 512 GB of memory. The I/O subsystem expands from 6 to 24 PCIe slots and adding PCIe expansion modules can further increase the number of I/O slots. Hardware to connect the cells together is added only as the server size increases.

System Partitioning

Each cell in an Express5800/A1160 system can function as an independent partition. In multiple-cell systems, two or more cells can be combined into a single partition. Each partition can run an operating system different from the operating system in any other partition.

Customer Installation and Servicing

Express5800/A1160 systems are designed to be installed by the customer without any special tools or training. Likewise, no special tools or training are required to service customer-replaceable units (CRUs).

Reliability, Availability, and Serviceability

Express5800/A1160 systems contain many features to detect and isolate faults. Systems with two or more cells provide 99.995% or better hardware availability.

Distributed System Management

Management controllers within each cell of an Express5800/A1160 system cooperate to provide management of the system. Hosted remotely, a server management application, such as NEC Server Management software, can monitor and control the system.
