around the globe.
These environments require servers
that are ruggedly dependable and designed with features
that can tolerate a component failure without total
shutdown.
xSeries 440 servers pack numerous
fault-tolerant and high-availability features into a
high-density, rack-optimized package that significantly
reduces the space needed to support massive network
computing operations. Features include:
•
Advanced memory subsystem uses ECC algorithm
based on memory symbols that provide these fault
tolerance features:
−
Memory scrubbing
—
Refreshes data to correct
single memory symbol errors from the previous
write and periodically tests all unused memory to
maintain error thresholds
−
Memory ProteXion
—
Four spare memory bits per
memory port allow data to be rerouted around bad
memory by use of the spare bits without replacing
the actual DIMMs
−
Memory mirroring
—
Helps protect against memory
failure by writing data to redundant memory ports
and is supported independent of operating systems
−
ECC RDIMMs combined with an integrated
advanced ECC memory controller with Chipkill
support
—
Corrects single-, two-, three-, and four-bit
memory errors to minimize disruption of service to
LAN clients
•
Active PCI-X slots
—
Hot-add and hot-swap adapters in
Windows
2000 and NetWare environments
•
Two standard SCA-2 compliant, hot-swap HDD bays
•
ECC L2 cache processors
—
Help improve data
integrity and reduce down time
•
PFA on HDD options, memory, processors, XceL4
cache, power supplies, and fans in conjunction with
IBM Director
—
Alert the system administrator of an
imminent component failure
•
Two, 1050-watt, hot-swap redundant power supplies
standard
—
Support n+n redundancy in full
configurations
•
Four hot-swap, multi-speed fans and up to 10 thermal
sensors
—
Provide ample cooling, cooling redundancy,
and enable individual fan replacement without
powering down the server
•
Integrated Remote Supervisor Adapter enabling
diagnostic, reset, POST, graphics, and auto recovery
functions from remote locations and monitoring of
temperature and fan speed
—
Alerts generated when
thresholds are exceeded
•
Information LED panel and innovative, front-accessible
pull-out, Light Path panel
—
Provide first-level
diagnostics and second-level component diagnostics
for easy diagnostics without removing the top cover
•
Easy top access to system board, adapter cards,
processor, and memory
•
CPU failure recovery in SMP configurations
—
Allows
a failed processor to be forced offline, the server
rebooted, an alert generated, and continued operation
with the working processors
XpandOnDemand Scalability:
xSeries 440 platforms are
designed for complex applications needed for your
business today, and feature XpandOnDemand scalability
from Enterprise X-Architecture technology for future
growth potential. Features include:
•
Massive I/O expansion
—
Support for up to 18 PCI-X
card slots:
−
Six Active PCI-X, full-length adapter card slots
standard
−
Optional RXE-100 Remote Expansion Enclosure
—
Supports up to 12 more Active PCI-X slots
•
Up to eight-way SMP operations with powerful new
Xeon MP processors today and up to 16-way in third
quarter 2002
•
Support for up to 32 GB of system memory
•
Two hot-swap drive bays
—
Support up to 146.8 GB of
internal data storage (using two 73.4 GB Ultra160
Hot-Swap HDDs)
•
Terabytes of external data storage
—
Support optional
EXP storage units, ServeRAID
SCSI controllers, and
FAStT Fibre Channel controllers and storage units
Systems Management:
xSeries 440 servers feature IBM
Director, a powerful, highly integrated systems
management software solution built on industry standards
and designed for ease of use. Now you can exploit your
existing enterprise or workgroup management
environments and use the Internet to securely access and
manage physically dispersed IT assets more efficiently.
It can help reduce costs through:
•
Reduced down time
•
Increased productivity of IT personnel and end users
•
Reduced service and support costs
IBM Director lets IT administrators view the hardware
configuration of remote systems in detail and monitor the
usage and performance of critical components such as
processors, HDDs, and memory.
IBM Director includes IBM Director Extensions, a portfolio
of server tools that integrates into the IBM Director
interface and works with the Remote Supervisor Adapter,
or other system management monitoring functions
contained in xSeries servers.
Typical functions and
monitoring capabilities can include:
•
PFA-enabled critical hardware components
•
Temperature
•
Voltage
•
Fan speed
•
Light Path Diagnostics
This gives the IT administrator comprehensive, virtual
on-site control of xSeries servers through the ability to
remotely:
•
Access the server regardless of its status
•
Inventory and display detailed system and component
information
•
View server bootup during POST
•
Browse and delete logs of events and errors
•
Reset or power-cycle the server
•
Run diagnostics, SCSI, and RAID setup during POST
•
Monitor thresholds on server health including:
−
Operating system load
−
POST time-out
−
Temperature
•
Set proactive alerts for critical server events including
PFA on:
−
Processors
−
XceL4 cache
