Gb Gigabit. A measurement of the rate at which the transfer of bits of data
occurs. Sometimes referred to as Gbps. Nominally, a Gb is a transfer rate of
1,000,000,000
(10
9
) bits per second.
For Fibre Channel transceivers or FC loops the Gb transfer rates are:
• 1 Gb is a transmission rate of 1,062,500,000 bits per second.
• 2 Gb is a transmission rate of 2,125,000,000 bits per second.
GUI Graphical User Interface. Software that displays the status of a storage system
and allows its user to control the storage system.
host A computer that runs user applications and uses (or can potentially use) one
or more virtual disks created and presented by the controller pair.
HSV Element Manager The graphical user interface (GUI) through which a user can control and
monitor a storage system. HSV Element Manager can be installed on more
than one storage management appliance in a fabric. Each installation is a
management agent. The client for the agent is a standard Web browser.
Versions later than 2.0 are called Command View EVA.
I/O module Input/Output module. The enclosure element that is the FC-AL interface to
the host or controller. I/O modules are bus speed specific, either 1 Gb or 2 Gb.
initialization A process that prepares a storage system for use. Specifically, the system
binds the controllers together as an operational pair and establishes
preliminary data structures on the disk array. Initialization also sets up the
first disk group, called the default disk group.
LED Light Emitting Diode. A semiconductor diode, used in an electronic display,
that emits light when a voltage is applied to it.
license key A WWN-encoded sequence that is obtained from the license key fulfillment
website.
logon Also called login, a procedure whereby a user or network connection is
identified as being an authorized network user
or participant.
management agent The Command View EVA software that controls and monitors the Enterprise
Storage System. The software can exist on more than one management
appliance in a fabric. Each installation is a management agent.
management agent event
A significant occurrence to or within the management agent software, or an
initialized storage cell controlled or monitored by the management agent.
metadata Information that a controller pair writes on the disk array. This information is
used to control and monitor the array and is not readable by the host.
OCP Operator Control Panel. The element that displays the controller’s status
using LEDs and an LCD. Information selection and data entry is controlled
by the OCP pushbuttons.
offline upgrade During an offline upgrade of the storage system software, VCS is upgraded
on the HSV controllers, while there is no I/O from the applications on the host
servers. During offline upgrades the HSV controllers are rebooted.
Offline upgrades are required when the HSV controllers or Storage
Management Appliance must be rebooted after loading VCS or other software.
