Term Lists
DHCP (Dynamic Host Conguration Protocol)
Server
A DHCP server manages network conguration
information for all the devices on a network. If
a compatible client device is connected to the
network, the DHCP server will automatically assign
necessary network information such as IP address,
subnet mask, gateway to the device. With a DHCP
server on the network, you don’t have to congure
network information for each device manually.
IP Address
A unique IP address identies each network device
on a subnet.
iSCSI (Internet Small Computer System Interface)
A communication protocol that allows SCSI device
communication over a gigabit Ethernet network.
Jumbo Frames
Ethernet communication with frames larger than the
standard 1518 bytes. Common jumbo frame sizes
are 4102 bytes, 7422 bytes, and 9694 bytes.
MAC (Media Access Control) address
The unique physical address assigned to each
network card. It consists of 3 bytes for the vendor
code (manufacturer ID) and 6 bytes for the individual
user code. Ethernet sends and receives frames
based on this address.
NTP (Network Time Protocol)
A protocol to correct time via the network. It
periodically synchronize time settings with that of
an NTP server to correct the time.
RAID (Redundant Arrays of Inexpensive Disks)
A technology that allows computer users to achieve
high levels of storage reliability from low-cost hard
drives by arranging them into arrays for redundancy.
Many types of RAID are available, including the well
known RAID 1 and RAID 5.
TCP/IP (Transmission Control Protocol / Internet
Protocol)
The standard communication protocol for Ethernet
networks and the Internet. It is a combination of the
TCP protocol (data separation and error detection)
and the IP protocol (providing a receiver and sender
IP address).
UPS（Uninterruptable Power Supply）
An Uninterruptable Power Supply contains a battery
for backup, and can run devices for a few minutes
when utility power is not available so that the
devices can be shut down safely.
