control the cluster as a single system and provides secure remote monitoring and management capabilities.
Clusterworx Master Host The Clusterworx Master Host is the host that controls the remaining hosts in a
cluster (for large systems, multiple masters may be required). This host is reserved exclusively for managing the
cluster and is not typically available to perform tasks assigned to the remaining hosts.

Evolocity II A host packaging solution from Linux Networx. It sits vertically in a rack and uses an
effective .8u of rack space.
Host An individual server or computer within the cluster that operates in parallel with other hosts in the
cluster. Hosts may contain multiple processors.
Icebox An important piece of the Linux Networx cluster management solution, the Icebox is an architectureindependent
hardware device that provides remote monitoring and advanced power control for hosts installed
in your cluster. The Icebox can monitor up to four processors per host and is accurate to ± 1 degrees Celsius.
The Icebox also contains advanced serial switching that allows administrators to maintain a redundant serial
network.

Rack Enclosure The rack used to hold Evolocity cluster hosts. Mounting rails used to hold hosts are 19
inches apart.
Serial Console port The Icebox port that connects to a remote computer via a serial connection. This is used
to access the Command Line Interface (CLI) for Icebox management.
Temperature/Reset ports Icebox ports that connect to the back of a corresponding host. These ports send
temperature and host status information to the user and provide the ability to remotely reset and control
beaconing for individual hosts.
