M
management network

A network that is primarily responsible for booting and installing the designated server and compute

nodes from the management server.

management server (MS)

An ESS node that hosts the ESS GUI and xCAT and is not connected to storage. It must be part of a

GPFS cluster. From a system management perspective, it is the central coordinator of the cluster. It

also serves as a client node in an ESS building block.

master encryption key (MEK)

A key that is used to encrypt other keys. See also encryption key.

maximum transmission unit (MTU)

The largest packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or

frame-based network, such as the Internet. The TCP uses the MTU to determine the maximum size of

each packet in any transmission.

MEK

See master encryption key (MEK).

metadata

A data structure that contains access information about file data. Such structures include inodes,

indirect blocks, and directories. These data structures are not accessible to user applications.

See management server (MS).

MTU

See maximum transmission unit (MTU).

N
Network File System (NFS)

A protocol (developed by Sun Microsystems, Incorporated) that allows any host in a network to gain

access to another host or netgroup and their file directories.

Network Shared Disk (NSD)

A component for cluster-wide disk naming and access.

NSD volume ID

A unique 16-digit hexadecimal number that is used to identify and access all NSDs.

node

An individual operating-system image within a cluster. Depending on the way in which the computer

system is partitioned, it can contain one or more nodes. In a Power Systems environment,

synonymous with logical partition.

node descriptor

A definition that indicates how ESS uses a node. Possible functions include: manager node, client

node, quorum node, and non-quorum node.

node number

A number that is generated and maintained by ESS as the cluster is created, and as nodes are added

to or deleted from the cluster.

node quorum

The minimum number of nodes that must be running in order for the daemon to start.

node quorum with tiebreaker disks

A form of quorum that allows ESS to run with as little as one quorum node available, as long as there

is access to a majority of the quorum disks.

non-quorum node

A node in a cluster that is not counted for the purposes of quorum determination.
