The IBM eServer BladeCenter JS20 blade server 8842-4Tx with low
profile handles in a BladeCenter T chassis is your key component for
building your telecommunications blade configuration.
The JS20 blade servers, in a BladeCenter or BladeCenter T chassis,
offer advanced application serving for Linux (SUSE and Red Hat), AIX 5L
V5.2, and AIX 5L V5.3 environments with performance, density, and
scalability. At your command are two powerful PowerPC 970 processors,
high-speed memory, dual Gigabit Ethernet connections, and comprehensive
high-availability and systems management features.
The JS20 2.2 GHz processor enhances performance for both Linux and AIX
applications as part of an innovative economic approach to the deployment
of large numbers of powerful servers. In the BladeCenter or BladeCenter
T chassis, the servers require less space and fewer power resources than
traditional rack-mounted servers. The JS20 4Tx model is designed with a
power management capability to give you the maximum uptime possible for
your systems. In short term extended thermal conditions, the 8842-4Tx
automatically reduces the frequency of the processor to maintain
acceptable thermal levels. Refer to NEBS in the Operating
environment for additional details.
Powerful blade-thin computing
The IBM eServer BladeCenter chassis and IBM eServer BladeCenter JS20
blade servers are key components to building your blade configuration.
Optionally available Ethernet, Fibre Channel, InfiniBand, and Myrinet
Cluster Expansion Cards for IBM eServer BladeCenter support advanced
configurations.
The Topspin IB Switch Module for IBM eServer BladeCenter delivers low
latency, high-bandwidth connectivity between InfiniBand connected

the customer prefers a scripting interface to perform cluster management
tasks. CSM provides full installation for Linux and a flexible command
line interface.
BladeCenter Management Module
Use the management module in the BladeCenter to manage the BladeCenter
and obtain vital system information about your installed JS20 blade
servers. The management module communicates with the blade servers
within the BladeCenter via an RS-485 intermanagement network. This
network relays vital information about individual blade servers such as:
- Temperature
- Voltages
- Power supply status
- Memory status
- Fan status
- HDD status
- Error and status log
You can receive the status and you can control all blade servers
within the BladeCenter. You can shut down and restart any blade server
from anywhere on the network to help save time and costs associated with
travel to the actual installation.
These manageability functions are provided through a self-contained
Web page, creating an easy and familiar way for administrators to
monitor, control, and maintain highly available BladeCenter
installations. The Management Module communicates to the JS20 blades
through serial-over-LAN interface.
Power management in the NEBS operating environment
The 8842-4Tx model is designed with a power management capability to
give you the maximum uptime possible for your systems.
In short term extended thermal conditions, rather than shutdown
completely, or fail, the JS20 4Tx model automatically reduces the
frequency of the processor to maintain acceptable thermal levels. The
processor frequency will automatically cycle back up as thermal
conditions improve. Power management is invoked only when the blade is
housed in a BladeCenter T chassis and only under the thermal conditions
described as short term in the high end of the NEBS extended temperature
range (41 to 55 degrees C). The BladeCenter Management Module (MM) is
notified when power management starts and again when it stops.
Appropriate entries are then made in the MM Event Log.
Applications could be sensitive to processor frequency changes. For
instance, frequency reductions could potentially impact benchmarking or
applications/tools that depend on execution times for accounting, CPU
utilization, or profiling. It is recommended that you check with your
individual application vendors to see if there are any possible impacts
and weigh the potential benefits and risks of 8842-4Tx power management
in the short term extended thermal NEBS environment before installing the
system.
Note: Short term refers to a period of not more than 96 consecutive hours
and a total of not more than 15 days in one year. (This refers to a
total of 360 hours in any given year, but no more than 15 occurrences
during that one-year period.)

Standards
The IBM eServer BladeCenter JS20 supports or complies with the
following standards:
- FCC - Verified to comply with Part 15 of the FCC Rules, Class A
- Canada ICES-003, issue 3, Class A
- UL 1950(1)
- CSA C22.2 No. 950
Note: (1) This server is certified by the respective UL agencies.
- The JS20 BladeCenter blades contain four DIMM sockets.
- A maximum of 8 GB of system memory is supported by adding a 2 GB
PC2700 CL2.5 ECC DDR SDRAM DIMM in each of the four DIMM sockets. The 2
GB DIMM is supported only on the 8842-42x and 8842-4Tx. All supported
system memory is addressable through direct memory access. The JS20
blade supports 512 MB, 1 GB, and 2 GB DIMM system memory options.
Supported DIMMs can coexist in the same server; however, memory DIMMs of
the same capacity must be installed in matched pairs.
- The BladeCenter chassis (8677-1XX/2XX/3XX) and BladeCenter T chassis
(8720-1RX/8730-1RX) support a mix of JS20, LS20, and HS20 blades.
- A keyboard/video/mouse is not supported on the JS20. The console
select button is also not supported on the JS20 blade; direct connections
should be made using Serial over LAN
- The second IDE connector supporting an IDE HDD cannot be used when a
JS20 Fibre Expansion card, BladeCenter Gigabit Ethernet Expansion Card,
Topspin IB Host Channel Adapter Expansion Card, or Myrinet Cluster
Expansion Card is installed due to mechanical reasons.
- The Topspin IB Host Channel Adapter Expansion Card is supported in
Linux environments only.
- The Myrinet Cluster Expansion Card in a JS20 is currently supported
only with Linux and AIX 5L V5.2 operating systems.
- Two 2,000-watt power modules are in the 8677-3XX BladeCenter with
support for two optional 2,000-watt power modules for redundancy and
robust configurations. Processor blades 1 to 6 receive their power from
power modules 1 and 2. Processor blades 7 to 14 receive their power from
power modules 3 and 4. If a JS20 blade is being installed in the
8677-1XX/2XX BladeCenter, the IBM eServer BladeCenter Power Module
Upgrade Guidelines (59P6598) will contain a table identifying the
power load factor of all possible blades.
- Two hot-swap 1,300-watt power modules are standard in the BladeCenter
T (8720-1RX/8730-1RX) to provide redundancy and power for bays 1 through
4 and switch modules 1 and 2. Two additional 1,300-watt power supply
modules are required to support installation of blade servers in the
BladeCenter T bays 5 through 8 and switch module bays 3 and 4.
- If your BladeCenter chassis was shipped before June 2003; check the
following items:
- An update to the customer interface card on the media tray may be
required for proper CD-ROM operation with the JS20 blade. To determine
the part number of your existing media tray, from the management module
Web interface, under the heading "Monitors" in the left hand column,
select Hardware VPD and then look at the Module Name "media tray". If
the FRU number of the media tray in your blade center is 59P6629, call
your hardware support center and request a free replacement media tray.
- Power modules may need to be upgraded to handle the additional power
requirements. The following link can assist you to determine if an
upgrade is required:
- http://www.pc.ibm.com/us/eserver/xseries/pdf/COGdec2003-US.pdf
- To prevent problems at installation, order any required upgrades
along with the JS20. The level of the ethernet switch module firmware
must be at level 81 or higher. To determine the revision level of your
existing firmware, from the management module Web interface, under the
heading "Monitors" in the left hand column, select Firmware VPD, then in
the table for "I/O Module Firmware VPD" look for the revision number of
the "Main Application 1" for the selected ethernet switch module. If you
need new firmware, the latest level is available for download from the
Internet at:
http://www-306.ibm.com/pc/support/site.wss/
document.do?lndocid=MIGR-50457
- BladeCenter JS20:
- Serial over LAN (SOL) is required to perform local or network
operating system or software installation on the JS20 blade server. SOL
communication requires a supported Gb Ethernet Switch Module to be
installed in switch module bay 1 of the BladeCenter chassis. If ethernet
booting is employed by the user, a second supported Gb Ethernet Switch
Module must also be installed.
- The BladeCenter JS20 does not support the KVM function that is
standard with the Management Module. The serial over LAN capability of
the Management Module is used on the JS20 as an alternative to the
functionality provided by the KVM feature.
- BladeCenter chassis:
- When using Serial over LAN (SOL) for operating system or software
installation (required for the JS20; optional for the HS20, or HS40), a
supported Gb Ethernet Switch Module is required in switch module bay 1 of
the BladeCenter chassis. If ethernet booting is employed by the user, a
second supported Gb Ethernet Switch Module must also be installed.
