SNMP server (See SNMP manager)
SoL (serial over LAN)
Access to the console of a server or other device that supports redirection of
serial server data to a dedicated Ethernet port. Permits access to and control of
the BIOS and operating system console over the LAN or Internet. Eliminates
the need for the device to have a serial port and the need for serial cabling to
enable console access. On the OnBoard, once a device’s SoL Ethernet port is
connected to one of the OnBoard’s private Ethernet ports, an authorized user
can access the server or a device’s console either through the “Device
console” or “devconsole” option (available on the Web Manager, rmenush,
or onbdshell) or through entering the devconsole command with ssh
on the command line).
SP (service processor)
Ethernet-based management controller on a server, which provides
out-of-
band management through an interface between the server’s administrator
and an internal baseboard management controller (BMC) that enables the
management features. Management features can include serial console
emulation (using Telnet or IPMI), KVM over IP, power control, sensor and log
information from the server hardware, and virtual media.
SRM (secure rack management)
An out-of-band infrastructure (OOBI) capability delivered by the AlterPath
OnBoard that isolates the management ports (emergency service ports) of
servers that have service processors from the production network. Physically
consolidates and logically secures the Ethernet connections between the
AlterPath OnBoard and the connected service processors. By providing IP
consolidation, SRM substantially lowers the cost and complexity of deploying
service processors. SRM also lowers the security risks of using service
processors by providing centralized authentication and user access control,
isolating vulnerable service processor protocols from the production network
and communicating with authenticated and authorized users over the public
network using higher-end secure protocols (such as SSH, SSL, and HTTPS).
