Glossary-19
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 chassis 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 functions of the SP are to
measure processor temperature, power supply values, and cooling fan status.
The SP can take autonomous action to preserve system integrity.
session time-out 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 email.
Simple Network
Management Protocol
(SNMP) A simple protocol used to exchange data about network activity. With SNMP,
data travels between a managed device and a network management station
(NMS). A managed device can be any device that runs SNMP, such as hosts,
routers, web servers, or other servers on the network.
Small Computer
System Interface
(SCSI) An ANSI standard for controlling peripheral devices by one or more host
computers. SCSI defines a standard I/O bus-level interface and a set of high-
level I/O commands.
Spanning Tree Protocol
(STP) A networking protocol based on an intelligent algorithm that allows bridges to
map a redundant topology and eliminates packet looping in local area
networks (LANs).
subnet A working scheme that divides a single logical network into smaller physical
networks to simplify routing. The subnet is the portion of an Internet Protocol
(IP) address that identifies a block of host IDs.
