Secure Sockets Layer
(SSL) A protocol that enables client-to-server communication on a network to be
encrypted for privacy. SSL uses a key exchange method to establish an
environment in which all data exchanged is encrypted with a cipher and
hashed to protect it from eavesdropping and alteration. SSL creates a secure
connection between a web server and a web client. Hypertext Transfer Protocol
Secure (HTTPS) uses SSL.
sensor data record
(SDR) To facilitate dynamic discovery of features, the Intelligent Platform
Management Interface (IPMI) includes this set of records that include software
information such as how many sensors are present, what type they are, their
events, threshold information, and so forth. The sensor data records enable
software to interpret and present sensor data without any prior knowledge
about the platform.
Serial Attached SCSI
(SAS) A point-to-point serial peripheral interface that links controllers directly to
disk drives. SAS devices include two data ports that enable failover
redundancy, which guarantees data communication through a separate path.
serial console A terminal or a tip line connected to the serial port on the service processor. A
serial console is used to configure the system to perform other administrative
tasks.
server certificate A certificate used with Hypertext Transfer Protocol Secure (HTTPS) to
authenticate web applications. The certificate can be self-signed or issued by a
Certificate Authority (CA).
Server Message Block
(SMB) protocol A network protocol that enables files and printers to be shared across a
network. The SMB protocol provides a method for client applications to read
and write to files on, and to request services from, server programs in the
network. The SMB protocol enables you to mount file systems between
Windows and UNIX systems. The SMB protocol was designed by IBM and
subsequently modified by Microsoft Corp. Microsoft renamed the protocol the
“Common Internet File System (CIFS).”
service processor (SP) A device used to manage server environmental, configuration, and service
functions, and receive event data from other parts of the system. It receives
data through sensor interfaces and interprets this data by using the sensor data
record (SDR) to which it provides an interface. The SP provides another
interface to the system event log (SEL). Typical function of the SP is to measure
processor temperature, power supply values, and cooling fan status. The SP
can take autonomous action to preserve system integrity.
session timeout A specified duration after which a server can invalidate a user session.
Simple Mail Transfer
Protocol (SMTP) A Transmission Control Protocol/Internet Protocol (TCP/IP) used for sending
and receiving e-mail.
