Glossary

B
BE

Boot environment. A bootable instance of the Oracle Solaris image. A BE can contain additional installed software packages.

BOOTP

Bootstrap Protocol.

boot pool

A special pool on firmware-accessible devices that contains the set of files required to boot the Oracle Solaris kernel for a BE. Each dataset in the boot pool is linked to a BE. See also BE and pool.

D
device-specifier

Most commands (such as boot) that require a device name accept either a full device path name or a device alias. In this book, the term device-specifier indicates that either a device path name or a device alias is acceptable for such commands.

DHCP

Dynamic Host Configuration Protocol. Software that automatically assigns IP addresses to clients on a TCP/IP network.

E
EEPROM

Electrically erasable programmable read-only memory.

eUSB

Embedded USB. A flash-based drive designed specifically to be used as a boot device. An eUSB does not provide storage for applications or customer data.

F
FCODE

FORTH code. FORTH is a programming language used in OpenBoot.

G
GB

Gigabyte. 1 gigabyte = 1024 megabytes.

GbE

Gigabit Ethernet.

H
HMAC

Hash message authentication code. Used in cryptography.

I
ILOM

See Oracle ILOM.

InfiniBand

A networking communications standard that features very high throughput and very low latency.

IPoIB

Internet protocol over InfiniBand.

iSCSI

Internet small computer system interface. An IP-based storage networking standard that enables a system to access storage across a network. In an iSCSI network, the remote storage is called the iSCSI target.

iSCSI using IPoIB

A boot process that enables a server or virtual machine to boot an iSCSI target accessible using IP over an InfiniBand network. See also IPoIB.

M
MAC address

Media access control address. A unique address associated with a network interface.

MMU

Memory management unit.

MSB

Most significant bit. The oem-logo variable is a 512-byte array, containing a total of 4096 bits arranged in a 64 x 64 array. Each bit controls one pixel. The MSB of the first byte controls the upper-left corner pixel. The next bit controls the pixel to the right of it, and so on.

N
NVMe

Non-Volatile memory express. A host controller specification.

NVRAM

Non-volatile random access memory.

NVRAMRC script

You can use the nvramrc configuration variable to store user-defined FORTH commands that are executed during start-up. The contents of the variable are called the NVRAMRC script.

O
OpenBoot

Oracle firmware that enables a PDomain to boot the Oracle Solaris OS. Provides an interface for testing hardware and software interactively.

Oracle ILOM

Oracle Integrated Lights Out Manager. The system management firmware that is preinstalled on the SPs.

P
pool

A logical group of devices describing the layout and physical characteristics of the available storage. Storage space for datasets is allocated from a pool. ZFS uses a model where storage devices are aggregated into a storage pool. See also boot pool and root pool.

POST

Power-on self-test. Diagnostic software that runs when the system is initialized from a reset or power-on.

PROM

Programmable read-only memory.

R
RARP

Reverse Address Resolution Protocol.

root pool

A dataset containing a complete Oracle Solaris image or a BE. See also pool.

root port

In a PCIe device path, the root port is always the second element (for example, /pci@300/pci@0).

RPC

Remote Procedure Call.

S
SCSI

Small computer system interface. A standard for attaching peripherals to computers.

T
TFTP

Trivial File Transfer Protocol.

V
virtual machine (VM)

The terms domain, guest, and virtual machine are often used interchangeably. A domain is a configurable set of resources, including memory, virtual CPUs, network devices, and disk devices, in which virtual machines run. A domain is granted virtual resources and can be started, stopped and restarted independently of other domains and of the host server itself. A guest is a virtualized operating system running within a domain. In this document, domain, guest and virtual machine are all referred to as virtual machines in which OpenBoot Firmware runs.

Z
ZFS

Zettabyte file system. A file system that uses storage pools to manage physical storage. See also BE, pool, boot pool, and root pool.
