Features
Performance
Impressive performance using the latest microprocessor technology. The basic
configuration is a 4-way building block (node), thus supporting up to four Intel
®
Xeon™ MP dual-core microprocessors. In the basic configuration, the system
comes with two microprocessors. You can install up to four microprocessors to
further enhance performance and symmetric multiprocessing (SMP) capability.
Scalability
Scalability redefines performance and investment protection by giving you the
ability to expand and scale the system as needs change. Scalability capabilities
include SMP expansion of up to four microprocessors, and resource configura-
tions for optimum performance.
The system is scalable and can be connected to multiple nodes so that you can
share resources between them. Starting from the 4-way base unit, adding a 4-
way extension unit, an 8-way (2-node) configuration is formed. Two 8-way
configuration sets may be connected to form a 16-way (4-node) configuration.
Large system memory
In the basic configuration, either 2 GB or 4 GB of memory is installed,
depending on the type of memory installied. Each node supports up to 32 GB
(64 GB) of system memory. The memory controller supports error correcting
code (ECC) for up to 16 industry-standard PC2-3200, 333 megahertz (MHz),
1.8 V, 240-pin, registered, double-data-rate (DDR) II, synchronous dynamic
random access memory (SDRAM) dual inline memory modules (DIMMs).
Additional features are Memory Scrubbing, Chipkill™, Redundant Bit Steering,
hot-plug Memory and Memory Mirroring.
Memory Scrubbing
Memory Scrubbing is an automatic regular test of all the system memory that
detects and reports memory errors that might be developing before they cause
a system outage.
When an error is detected, Memory Scrubbing determines if the error is recov-
erable or not. If it is recoverable, Redundant Bit Steering is enabled and the data
that was stored in the damaged locations is rewritten to a new location. The
