Reduce downtime with enhanced memory protection
With the rapid price decline of memory, there has been an increase in
the amount of memory usage in systems. With more memory in use,
the potential for memory failure increases, which increases the impor-
tance of memory reliability features in the platform. New DP Intel Xeon
processor-based server platforms offer increased reliability over previ-
ous platforms through new features implemented in the chipset mem-
ory controller:
• Memory scrubbing: The system constantly tests the memory for
soft failures. When a failure is detected, a warning can be issued
or spare memory can be invoked to ensure continued operation.
• Memory mirroring
5
: Two copies of the memory’s content are
kept. If one set of memory fails, the other set enables continued
operation and system availability.
• On-line spare memory: Reserved memory can be invoked and
brought online when there is a failure in the memory currently in use.
• Dual-channel failover to single-channel operation: If memory
in one of the two memory channels fails, the system can fail-over
to single-channel operation, allowing continued system availability
until the failed memory can be replaced.
• x4 Single Device Data Correction (x4 SDDC): In a x4 DDR2 or
DDR memory device, the Intel
®
x4 SDDC provides error detection
and correction for 1 to 4 data bits within a single device or error
detection for up to 8 data bits within two devices.
PCI Express Reliability/Availability/Serviceability (RAS)
features keep you up and running
PCI Express is rich in RAS capabilities:
•Built-in clocking for Data Integrity Checking
• Advanced error logging and reporting through IPMI
• Hot-plug
5
capability simplifies replacement of failed devices and
reduces system downtime, while allowing mix and match of
peripherals and systems or I/O chassis from different vendors
(something that is not generally possible in today’s environment)
•A high-performance yet cost-effective RAID can be
implemented on the server board using the Intel
®
IOP332
I/O processor, designed to connect directly to the chipset’s
memory controller via PCI Express
Summary
Dual-processor server platforms based on the 64-bit Intel Xeon
processor with 2MB L2 cache and the Intel E7520 chipset or
the Intel E7320 chipset deliver outstanding computing power
and flexibility, with the cost-effectiveness you need today and
the headroom you need to migrate to 64 bit in the future.
In addition, these new platforms, backed by the Intel Xeon
processor brand, offer optimized power consumption, plus
improved platform reliability and manageability compared to
previous-generation server platforms to further lower TCO
and maximize your return on investment.
