Server Technical Overview

Operating Systems
1-2
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.
