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.
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. IOMF 2
CRUs are supported on G06.10 and later software release version updates (RVUs).
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.
iPAQ Desktop. An Internet-based computing model and business PC used for Internet
access, mainstream computing, and running the Windows 2000 Professional operating
system. The iPAQ Desktop is designed to reduce hardware and software conflicts; it
eliminates Industry Standard Architecture (ISA)/Peripheral Component Interconnect
(PCI) slots and uses Universal Serial Bus (USB) ports with the Windows 2000 or
Windows ME operating system.
IPC. See interprocessor communications (IPC).
IPU. See instruction processing unit (IPU).
