service covers and to pull out components
for servicing.
service information message (SIM)
A message sent by a storage server to
service personnel through a System z
operating system.
service personnel

or companies authorized to service the
DS8000. The terms service provider, service
representative, and IBM service support
representative (SSR) refer to types of
service personnel. See also service support
representative.
service processor

data. All volumes in a session must
transfer their data successfully to the
remote site before the increment can be
called complete.
SFP Small form factor pluggables.
shared storage
Storage that is configured so that multiple
hosts can concurrently access the storage.
The storage has a uniform appearance to
all hosts. The host programs that access
the storage must have a common model
for the information on a storage device.
The programs must be designed to handle
the effects of concurrent access.
shortwave laser adapter

SNMP agent
A server process that resides on a
network node and is responsible for
communicating with managers regarding
that node. The node is represented as a
managed object, which has various fields
or variables that are defined in the
appropriate MIB.
SNMP manager
A managing system that runs a managing
application or suite of applications. These
applications depend on Management
Information Base (MIB) objects for
information that resides on the managed
system. Managers generate requests for
this MIB information, and an SNMP agent
on the managed system responds to these
requests. A request can either be the
retrieval or modification of MIB
information.
