IOMF CRU
IOMF CRU. See I/O multifunction (IOMF) CRU.
IOMF 2 CRU. See I/O multifunction (IOMF) 2 CRU.
I/O multifunction (IOMF) CRU. (1) An 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.
I/O multifunction (IOMF) 2 CRU. An 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.
IOP. See input/output process (IOP).
IP. See Internet protocol (IP).
IP address. An address that uniquely identifies a specific host system within a network to
the Internet protocol (IP). An IP address consists of two parts: a network address,
which identifies the network, and a local address, which identifies the host within the
network. IP routes data between source and destination IP addresses.
IPC. See interprocessor communications (IPC).
IPU. See instruction processing unit (IPU).
ISO. International Organization for Standardization. ISO is an international body that drafts,
discusses, proposes, and specifies standards for network protocols. ISO is best known
for its seven-layer reference model that describes the conceptual organization of
protocols.
ISO is sometimes called the
International Standards Organization. Although ISO is the
official abbreviation, it does not correspond to the organization’s name in any
language.
ISO 646. An ISO standard for representing characters in languages based on the Roman
alphabet. Like ASCII, ISO 646 uses only 7 bits of each 8-bit byte to represent data.
Contrast with ISO 8859
