internet protocol See IP
IP Internet Protocol. The network layer protocol for the Internet protocol suite that provides the basis for the
connectionless, best-effort packet delivery service. IP includes the Internet Control Message Protocol
(ICMP) as an integral part. The Internet protocol suite is referred to as TCP/IP because IP is one of the two
most fundamental protocols.
IP address See Internet address
Jumbo packets Ethernet packets that are larger than the Ethernet standard of 1500 bytes.
kernel The core part of the operating system that controls processes, system scheduling, memory management,
input and output services, device management, network communications, and the organization of the file
systems.
LND Lustre Networking Device layer that implements a network type.
LNET Lustre Networking Model API.
Lustre File System A networked file system that is coherent, scalable, parallel, and targeted towards high performance
technical computing environments.
MAC address Machine Access Control Address; also known as a hardware address. The physical address that
identifies an individual Ethernet controller board. A MAC address is a 48-bit number that is typically
expressed in the form
xx-xx-xx-xx-xx
where
x
is a hexadecimal digit or
a
-
f
.
MDS server The ProLiant DL server that the MDS service runs on. Usually the second server in the system.
See also MDS service
MDS service The software that serves meta-data requests from clients and Object Storage Servers. There is an MDS
service associated with each file system.
See also MDS server
mount The operation of attaching a file system to an existing directory and making the file system available for
use. Lustre file systems are mounted using the
sfsmount
(8) command.
See also unmount
mount point A directory that identifies the point in the file system where another file system is to be attached.
MPI Message Passing Interface. A library specification for message-passing, proposed as a standard by a
broadly based committee of vendors, implementors, and users.
MTU Maximum Transfer Unit. The largest IP packet size that can be sent or received by a network interface.
netmask A 32-bit bit mask that shows how an Internet address is to be divided into network and host parts.
network Two or more computing systems that are linked for the purpose of exchanging information and sharing
resources.
Network File System See NFS
NFS Network File System. A service that allows a system (the server) to make file systems available across a
network for mounting by other systems (clients). When a client mounts an NFS file system, the client’s
users see the file system as if it were local to the client.
NFS mounted A file system that is mounted over a network by NFS rather than being physically connected (local) to the
system on which it is mounted.
See also NFS
NID Lustre networking address. Every node has one NID for each network.
Object Storage Server A ProLiant DL server that OST services run on.
See also OST service
