expansion service processor (ESP)
expansion service processor (ESP). A service processor (SP) that is not a master service 
processor (MSP). ESPs occur in pairs in groups 02 through nn (not in group 01). See 
also master service processor (MSP).
explicit DLL. See explicit dynamic-link library (explicit DLL).
explicit dynamic-link library (explicit DLL). A dynamic-link library (DLL) that is named in 
the libList of a client or is a native-compiled loadfile associated with a client.
export. To offer a symbol definition for use by other loadfiles. A loadfile exports a symbol 
definition for use by other loadfiles that need a data item or function having that 
symbolic name.
export digest. A mathematical hash of the exported symbol names and locations in a 
library. Two libraries with the same export digest are interchangeable in that they both 
export the same symbols at the same locations; they are not necessarily semantically 
equivalent.
extended link format (ELF). A standard binary file format common on UNIX systems. The 
ELF format is used for position-independent code (PIC) files.
extended link format (ELF). A standard binary file format common on UNIX systems. The 
ELF format is used for position-independent code (PIC) files.
fabric. A complex set of interconnections through which there can be multiple and (to the 
user) unknown paths from point to point. The term fabric is used to refer to the X or Y 
portion of the ServerNet communications network; for example, the X fabric.
fastLoad. An optimization that allows the loader to avoid reading symbols and binding 
symbolic references when loading a program or dynamic-link library in an environment 
equivalent to that of a previous load. See also preset, cached bindings, and library 
import characterization (LIC).
fault tolerance. The ability of a computer system to continue processing despite the failure 
of any single software or hardware component within the system.
field-replaceable unit (FRU). A unit that can be replaced in the field only by qualified 
personnel trained by HP and cannot be replaced by customers. A unit is classified as a 
FRU because of safety hazards such as weight, size, sharp edges, or electrical 
potential; contractual agreements with suppliers; or national or international standards. 
See also customer-replaceable unit (CRU).
filename. In the Open System Services (OSS) environment, a component of a pathname 
containing any valid characters other than slash (/) or null. See also file name.
file name. A string of characters that uniquely identifies a file.
In the PC environment, file names for disk files normally have at least two parts (the 
disk name and the file name); for example, B:MYFILE.
