System Management Workstation (SMW)
The System Management Workstation (SMW) is the system administrator's console for managing a Cray system.
The SMW is a server that runs the CentOS (version 7.3) operating system, Cray developed software, and third-
party software. The SMW is also a point of control for the Hardware Supervisory System (HSS). The HSS data is
stored on an internal hard drive of the SMW.
The SMW provides shell and web access to authorized users to perform administrative and monitoring tasks. The
Nagios Core service also runs on the SMW.
Most system logs are collected and stored on the SMW. The SMW plays no role in computation after the system
is booted. From the SMW an administrator can initiate the boot process, access the database that keeps track of
system hardware, analyze log messages, and perform standard administrative tasks.
CAUTION: The SMW is a critical system component, which facilitates the operation of other hardware
and software components. Therefore, it is important that all instructions in this publication be followed
before making any changes/reconfigurations to the SWM, as well as before restarting the SMW.

About the Integrated Dell Remote Access Controller (iDRAC)
The iDRAC is a systems management hardware and software solution that provides remote management
capabilities, crashed system recovery, and power control functions for the System Management Workstation
(SMW). The iDRAC alerts administrators to server issues, helps them perform remote server management, and
reduces the need for physical access to the server. The iDRAC also facilitates inventory management and
monitoring, deployment and troubleshooting. To help diagnose the probable cause of a system crash, the iDRAC
can log event data and capture an image of the screen when it detects that the system has crashed.
For more information about the iDRAC, refer to online documentation at
