Support for Virtualization Through Logical Domains
The SPARC Enterprise T5440 server supports the use of open source Logical Domains
(LDoms) technology. Through the use of the Solaris OS and the built-in server firmware, and
by installing the Logical Domains Manager software, you can virtualize the compute services
that run on your server.
A logical domain is a discrete, logical grouping with its own operating system, resources,
and identity within a single computer system. Each logical domain can be created, destroyed,
reconfigured, and rebooted independently, without requiring a power cycle of the server.
You can run a variety of applications software in different logical domains and keep them
independent for performance and security purposes.
Each logical domain can be managed as an entirely independent machine with its own
resources, such as:
Kernel, patches, and tuning parameters
User accounts and administrators
Network interfaces, MAC addresses, and IP addresses
Each logical domain can interact only with those server resources made available to it. The
configuration is controlled using the Logical Domains Manager.
For more information on Logical Domains, refer to the Logical Domains (LDoms)
Administration Guide.
Remote Manageability With ILOM
The Integrated Lights Out Manager (ILOM) feature is a system controller, built into the
server, that enables you to remotely manage and administer the server.
The ILOM software is preinstalled as firmware, and initializes as soon as you apply power to
the system.
ILOM enables you to monitor and control your server over an Ethernet connection (supports
SSH), or by using a dedicated serial port for connection to a terminal or terminal server.
ILOM provides a command-line interface and a browser-based interface that you can use to
remotely administer geographically distributed or physically inaccessible machines. In
addition, ILOM enables you to run diagnostics (such as POST) remotely that would
otherwise require physical proximity to the server’s serial port.
