But, how do you manage it all?
Administrative Challenges of Clusters
Hardware Failures
Remote Monitoring and Access
Software Upgrades and Cloning
Linux NetworX Evolocity™
First vertical-node design
AMD Athlon™ or Intel Pentium®
Single or Dual processors
Fast Ethernet included; High-speed options available (Dolphin, Myrinet, and Quadrics)
Pre-configured to use ICE™ because real cluster management takes both hardware and software
No one has built Linux clusters longer than Linux NetworX
Horizontal design increases heat Vertical design allows for better air flow
Vertical rack-mount design increases system component
reliability
Evolocity decreases heat by 12° C compared to the average 2U solution
Evolocity™ Benefits
Integrated Cluster Environment (ICE)™
ClusterWorX® - Cluster management software
ICE™ Box - Management hardware appliance
“As Lawrence Livermore National Laboratory continues to add to parallel capacity resources, cluster management becomes a more critical issue, which is why we required the ICE management tool from Linux NetworX.”
Lawrence Livermore National Laboratories Dr. Mark Seager, Asst. Dept. Head for
TeraScale Systems
ClusterWorX® and ICE Box
Integrated Power and Temperature Monitoring
Serial Console access to each node – the only serial connection that does not require any rack space
View and assign node properties and network configuration
ClusterWorX® Events
Events perform automatic system administration tasks
Example:
If (Temperature >= 60 °)
Shutdown the node
Send email when an event has been triggered.
ClusterWorX® Plug-in
Perl and native Linux plug-in support allows you to add custom monitors and actions
Over 40 built-in near real-time monitors
Three types of plug-in: Monitor –
constantly monitors the node
Startup – read once when node boots
Execute – act upon a system trigger

ClusterWorX® Monitoring
Remote Access through Web Browsers
Examine Load Averages, CPU Usage, Memory Usage, and Configuration
Manage the cluster using Subgroups
ICE™ Box Remote Access and Control
Adjust identification power, temperature, and reset with LED control panel.
ICE Box folds open for easy access,
then folds-up neatly.

Background Slow computation was costing time and money - the legacy
system would have taken 38 years to complete!
Solution Linux NetworX delivered a 74-node system with 150 GigaFlops of
Performance running with ICETM Cluster Management
Results ICETM reduced administrative overhead by $10,000 per year Their computation completed on the Linux NetworX cluster in 34
days
Performance in Bioinformatics
An increase of over 400 times the speed
Linux NetworX Roadmap
Clustrix 1.0 (2002) LNXI distribution for clustering Integrated MPICH, Myrinet,
PBS, and Maui
ICE Box 3.0 (2002) IPMI-based System Monitoring SNMP MIB Agents
LinuxBIOS 1.0 (2002) BIOS reboot in under 3 seconds Remotely manage BIOS
settings
Oracle 9i RAC (2002) Cluster transparent Database
