HP Integrity
NonStop™
NS-series servers
The HP NonStop servers having product numbers beginning with the letters NS. These servers
implement the ServerNet architecture and run the HP NonStop operating system.
HP NonStop™
operating system
The operating system for HP NonStop systems.
HP NonStop™
S-series servers
The set of servers in the HP NonStop range of servers having product numbers beginning with
the letter S. These servers implement the ServerNet architecture and run the HP NonStop operating
system.
HP NonStop™
Transaction
Management
Facility (TMF)
HP software that provides transaction protection and database consistency in demanding online
transaction processing (OLTP) and decision-support environments. It gives full protection to
transactions that access distributed SQL and Enscribe databases, as well as recovery capabilities
for transactions, online disk volumes, and entire databases.
HP Open System
Management
(OSM) product
See OSM.
HP Tandem
Advanced
Command
Language (TACL)
The user interface to the HP NonStop operating system. The TACL product is both a command
interpreter and a command language. Users can write TACL programs that perform complex
tasks simply or provide a consistent user interface across independently programmed applications.
I/O adapter
module (IOAM)
A collection of modular components that provides I/O connectivity and can include ServerNet
switch boards, Fibre Channel ServerNet adapters (FCSAs), Gigabit Ethernet 4-port ServerNet
adapters (G4SAs), fans, and power supplies. In the IOAM, each module is a logical entity that
represents a single service domain.
I/O cabinet See I/O enclosure.
I/O enclosure An HP NonStop S-series system enclosure containing exactly one module, which includes ServerNet
adapters, disk drives, components related to the ServerNet fabrics, and components related to
electrical power and cooling for the enclosure. An I/O enclosure is identical to a processor
enclosure, except that it contains I/O multifunction (IOMF) customer-replaceable units (CRUs)
instead of processor multifunction (PMF) CRUs.
I/O multifunction
(IOMF) 2 CRU
A HP NonStop S-series customer-replaceable unit (CRU) that connects an I/O enclosure to a
processor enclosure through a ServerNet cable and supplies power to the components within the
IOMF 2 CRU as well as redundantly to the disk drives, SCSI terminators, and ServerNet adapters
in that enclosure. The IOMF 2 CRU contains a power supply, a service processor (SP), a ServerNet
router 2, an Ethernet controller, three configurable ServerNet ports, and three SCSI ServerNet
addressable controllers (S-SACs) in a single unit. IOMF 2 CRUs are supported on G06.10 and
later software RVUs.
I/O multifunction
(IOMF) CRU
1. A HP NonStop S-series customer-replaceable unit (CRU) that connects an I/O enclosure to a
processor enclosure through a ServerNet cable and supplies power to the components within the
IOMF CRU as well as redundantly to the disk drives, SCSI terminators, and ServerNet adapters
in that enclosure. The IOMF CRU contains a power supply, a service processor (SP), a ServerNet
router, an Ethernet controller, an external ServerNet port, and three SCSI ServerNet addressable
controllers (S-SACs) in a single unit.
2. A collective term for both IOMF CRUs and IOMF 2 CRUs when a distinction between the two
types of CRUs is not required.
input/output
process (IOP)
A running program (part of the HP NonStop operating system) that manages the I/O functions
for one or more ServerNet addressable controllers (SACs) of the same type.
interactive mode A mode of operation that is characterized by having the same input and output device (a terminal
or a process) for the session. If a terminal is used, a person enters a command and presses Return.
If a process is used, the system interface waits for the process to send a request and treats the
process in the same manner as a terminal. Contrast with noninteractive mode.
Internal disk A SCSI disk that resides in slots 1 through 18 of a NonStop S-series system enclosure.
