Chapter 4: System Modules
CMM Functions
The following sections describe local functions and remote functions of the CMM. With
only minor exceptions, all of the remote functions can be performed by one of three
mechanisms: web-based access to the CMM module, access to the CMM using
IPMIview , a client tool implemented in Java, or via IPMItool commands (DOS
commands or shell scripted commands).
When the web based browser is used, the CMM acts as a web server, requiring a higher
bandwidth connection to the CMM. If there are any bandwidth constraints, IPMI will
provide a superior experience. Additionally, since graphical updates are provided by
client-side Java, IPMIview can also be a superior user experience.
IPMItool on the other hand can provide the ability to issue similar/identical commands to
many 8U SuperBlade enclosures/CMM’s to manage all of them in a similar way.
Remote KVM over IP
Remote KVM over IP is independent from local KVM (although local KVM can operate in
parallel with Remote KVM). Remote KVM encrypts all communication between the
remote user and the CMM.
To Use: Remote KVM over IP is initiated with the management software (IPMI View or
Web-based utility). Attach the LAN cable to the LAN port on the CMM module then refer
to
"Web-based Management Utility" on page 4-12 to login and use either utility.
Remote Storage (Virtual Media)
The Remote Storage function allows the user to connect to a remote storage device
(such as a floppy, hard disk, or USB storage device) and access the device as if it were
local. This can be used not only to read and write to remote storage devices but to load
an operating system from a remote drive.
Serial Over LAN (SOL)
Serial Over LAN allows you to redirect the input and output of a serial port via IPMI in
order to manage blade modules from a remote location.
To Use: Serial Over LAN can be activated via the Web-based Management utility. See
the Web-based Management Utility User’s Manual for the procedure to initiate SOL.
Monitoring Functions
Used in conjunction with IPMI or the Web-based Management utility, the CMM module
can monitor and provide information on the hardware health of the blade modules and
the system as a whole. In addition to the monitoring functions, you can remotely power
on, power off or reboot a system.
Health information includes:
• Temperature levels
• Fan speeds
