6.9.4 Ethernet Configuration
Use this feature to set the controller Ethernet port configuration.
A customer doesn’t need to create a reserved space on the arrays
before the Ethernet port and HTTP service are working. The firm -
ware-embedded web browser-based RAID manager can access it
from any standard internet browser or from any host computer
either directly connected or via a LAN or WAN with no software or
patches required.
DHCP (Dynamic Host Configuration Protocol) is a protocol that
lets network administrators manage centrally and automate the
assignment of IP (Internet Protocol) configurations on a computer
network. When using the internet’s set of protocols (TCP/IP), in
order for a computer system to communicate to another com-
puter system, it needs a unique IP address. Without DHCP, the
IP address must be entered manually at each computer system.
DHCP lets a network administrator supervise and distribute IP
addresses from a central point. The purpose of DHCP is to provide
the automatic (dynamic) allocation of IP client configurations for
a specific time period (called a lease period) and to eliminate the
work necessary to administer a large IP network.
To configure the RAID controller Ethernet port, move the cursor
bar to the main menu and click on the “System Controls” link.
The “System Controls” menu will show all items. Move the cursor
bar to the “Ethernet Configuration” item, then select the desired
function.
