small form factor
pluggable
transceivers
SFP transceivers. Laser-based optical transceivers for a wide range of
networking applications requiring high data rates. The transceivers,
which are designed for increased densities, performance, and
reduced power, are well-suited for Fibre Channel applications.

stored addresses
In S/390 mode, a method for configuring addresses.
subnet
A portion of a network that shares a common address component. On
transmission control protocol/Internet protocol (TCP/IP) networks,
subnets are defined as all devices whose IP addresses have the same
prefix. Dividing a network into subnets is useful for both security and
performance reasons. IP networks are divided using a subnet mask.
subnet mask
A mask used by a computer to determine whether another computer
with which it needs to communicate is located on a local or remote
network. The network mask depends upon the class of networks to
