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
