Glossary
A
- authentication server
- The LDAP server that is
used to authenticate users to access Lenovo XClarity Administrator, CMMs, and baseboard management controllers. Lenovo XClarity Administrator supports an internal LDAP server that
is part of the management server or an external LDAP server that resides on a remote system and is provided by the
customer.
B
- baseboard management controller (BMC)
- A generic
term for a service processor in a server that combines systems-management
functions, video adapter, remote presence, and blue-screen capture
features in a single chip.
- bay
- A physical space into which a device or filler
can be physically mounted and connected to power and data (for example,
a fan, power supply, disk drive, server, or CMM).
- bundle
- A file that contains a set of device drivers
and boot files for a specific operating-system release.
C
- cabinet
- See rack.
- Call Home
- A communications link that is established between Lenovo XClarity Administrator and the Lenovo Support Center. When a managed system requires service, Lenovo XClarity Administrator automatically collects diagnostic data from that system,
and uses this link to open a problem ticket with the Lenovo Support Center.
- category pattern
- A set of related firmware settings
that can be reused in multiple server patterns.
- chassis
- A metal frame in which various electronic
components are mounted.
- Chassis Management Module (CMM)
- A service processor
that is used to configure and manage components in a Flex chassis.
- centralized user management
- See managed
authentication.
- compliance policy
- See firmware compliance
policy.
- compute node
- An independent server that is supported
in a Flex chassis and contains one or more microprocessors, memory,
storage, and network controllers. It runs its own operating system
and applications.
- Configuration Patterns
- A set of common configuration settings, including
local storage configuration, I/O adapter configuration, boot settings,
and other management controller and UEFI firmware settings that you
can use to quickly configure multiple servers at one time.
- cryptography
- The transformation of data to conceal
its information content and to prevent its unauthorized use or undetected
modification. Data is encrypted into an unreadable format, called
cipher text. A cipher key is used to decipher (or decrypt) the content
into plain text.
D
- device
- A system or component that Lenovo XClarity Administrator manages currently.
E
- endpoint
- See device.
- Encapsulation
- Firewall rules on the device are configured so
that incoming requests are accepted only from Lenovo XClarity Administrator.
- event forwarder
- Information about where to send
events that occur for a specific device, event class, event severity,
and component. Events can be forwarded using syslog, SNMP traps, or
email notifications.
F
- filler
- A device in the rack other than a supported
manageable device (for example, a network switch or KVM console).
- firmware compliance policy
- A policy that ensures
that the firmware on specified devices is at the current or specified
levels. The policy identifies which devices are monitored and which
firmware-update level must be installed to keep the devices in compliance.
- firmware-updates repository
- A repository that
contains the product catalog and the firmware-update packages that
have been downloaded using Lenovo XClarity Administrator or manually downloaded from the web and then imported.
I
- Integrated Management Module (IMM)
- See baseboard management controller
L
- local authentication
- Active user accounts on
the devices or in Active Directory are used to authenticate managed
devices.
M
- managed authentication
- Active user accounts that
are defined in Lenovo XClarity Administrator are used to authenticate managed devices.
- management server
- See Lenovo XClarity Administrator.
- management controller
- See baseboard
management controller
P
- product catalog
- Contains information about firmware
updates that are currently available in the Support website for all
devices that are supported by Lenovo XClarity Administrator. The catalog organizes the firmware updates in update
packages by device type.
- privilege
- A set of permissions for a specific
action or set of actions.
R
- rack
- The cabinet in which the chassis, servers,
and switches are stored.
- rack server
- A stand-alone server that is supported
in a rack but outside of the Flex chassis and contains one or more
microprocessors, memory, storage, and network adapter. It runs its
own operating system and applications.
- rack view
- A graphical view of the front rack
that shows each device in the rack, including chassis, rack and tower
servers, top-of-rack switches, and fillers.
- repository
- A container of preloaded and imported
files (such as firmware updates and OS images)
- role
- Controls user access to resources and limits
the tasks that users can perform on those resources.
- role group
- Assigns roles to user accounts that
are defined and managed in the authentication server.
S
- server
- A generic term to mean a compute node,
rack server, or tower server.
- server pattern
- A set of configuration settings
that can be used by one or more servers of the same type. The pattern
contains several categories of settings, such as system information
and management interface information. These categories can also be
patterns so that you do not have to specify the same information multiple
times.
- server profile
- Deployable patterns for one or
more devices; stored in the LDAP repository.
- service forwarder
- Information about where to
send diagnostic files when a serviceable event occurs, using either Call Home or SFTP.
- slot
- A physical space into which a device can
be physically mounted (for example, an I/O device, memory, or CPU).
- stacked switches
- A group of switches that operate
as a single network switch. The stack includes a master switch and one or more member switches.
- storage device
- Hardware that provides shared
storage capacity to servers. A storage device can include other storage
devices that work together.
- system
- A chassis, server, or switch that Lenovo XClarity Administrator can discover and manage.
T
- tower server
- A stand-alone server that is supported
outside of a rack and contains one or more microprocessors, memory,
storage, and network controllers. It runs its own operating system
and applications.
U
- Unified Extensible Firmware Interface (UEFI)
- A specification that details the interface between the operating
system and the platform firmware at boot time. It is not specific
to any processor architecture.

updates for a specific device.
V
- virtual appliance
- The Lenovo XClarity Administrator management server plus a virtual machine, such as ESXi
or Microsoft Hyper-V.
- virtual local area network (VLAN)

devices that behave as if they exist in a single LAN despite their
physical location, and share a single broadcast and multicast domain.
- VLAN tagging
- The practice of inserting a tag
(or ID) into a packet header to identify which VLAN the packet belongs
to. Switches use the VLAN tag to determine which interfaces to send
a broadcast packet to.
X
- XClarity Controller (XCC)
- See baseboard
management controller
