HP Virtual Connect Enterprise Manager Software - Manual (Page 191)

Onboard
Administrator The Onboard Administrator is the central point for controlling an entire c-Class rack. It offers
configuration, power, and administrative control over the rack, and its associated blades (Compute
Servers), blade management processors (iLOs), network switches (depending on the models of
switches used) and storage components (such as SAN or SATA). The Onboard Administrator is
a single management processor, with shared resources to an optional backup twin processor for
failover.
profiles Virtual Connect server profile is a logical grouping of attributes related to server connectivity that
can be assigned to a server blade.
racks A set of components cabled together to communicate between themselves. A rack is a container
for an enclosure.
RADIUS Remote Authentication Dial-In User Service. An authentication and accounting system used by
many ISPs. When you dial in to the ISP you must enter your username and password. This
information is passed to a RADIUS server, which checks that the information is correct, and then
authorizes access to the ISP system.
reclaim external Returns the external address to VCEM allocation.
server blade Typically a very dense server system containing microprocessors, memory, and network connections
that can be easily inserted into a rack-mountable enclosure to share power supplies, fans, switches,
and other components with other server blades. Server blades tend to be more cost-efficient,
faster to deploy, and easier to adapt to growth and change than traditional rack-mounted or
tower servers.

shared uplink port An Ethernet uplink port that carries the traffic for multiple Virtual Connect networks. Each associated
Virtual Connect network is mapped to a specific Virtual Local Area Network (VLAN) on the
external connection, and appropriate VLAN tags are removed or added as Ethernet packets enter
or leave the VC Domain.
shared uplink port
set A set of Ethernet uplinks that are used together to provide improved throughput and availability
to a group of associated Virtual Connect networks. Each associated Virtual Connect network is
mapped to a specific VLAN on the external connection and appropriate VLAN tags are removed
or added as Ethernet packets enter or leave the VC Domain.
Simple Network
Management
Protocol One of the management protocols supported by HP Insight Control. Traditional management
protocol used extensively by networking systems and most servers. MIB-2 is the standard
information available consistently across all vendors.
slice Two virtual connect modules placed in horizontally adjacent interconnected bays.
Smart Link A feature that, when enabled, configures a Virtual Connect network so that if all external uplinks
lose link to external switches, Virtual Connect will drop the Ethernet link on all local server blade
Ethernet ports connected to that network.
SSL Secure Sockets Layer
stacking port A VC-Enet module external port used to connect to other VC-Enet modules within an active VC
Domain. Stacking ports are automatically identified by the VC-Enet modules. The port number
(port ID) is illuminated amber.
system Nodes on the network that communicate through TCP/IP. To manage a system, some type of
management protocol (for example, SNMP, DMI, or WBEM) must be present on the system.
Examples of systems include servers, workstations, desktops, portables, routers, switches, hubs,
and gateways.
TACACS+ Terminal access controller access-control system. Allows a remote access server to communicate
with an authentication server in order to determine if the user has access to the network.
uncleared event
status Events that have a Critical, Major, Minor, Normal, or Informational severity.
Critical.
A failure has occurred, and immediate attention is required.
