NOTE:
The Health page provides a visual status of the chassis front and rear
views showing the chassis drives (0-11), the power supplies (PS1 and PS2),
and OS internal drives (12 and 13). This page also lists the major components
in the System Hardware Health table; such as the power supplies, fans,
temperature, storage, network interface cards (NICs), CPU, and DIMM (dual
in-line memory module).
Understanding DR4000 System NICs and Ports
The DR4000 system supports the use of two types of network interface cards
(NICs):
• 1-Gigabit Ethernet (GbE) two-port (10-Base T) using CAT6 cabling
• 10-GbE two-port (100-Base T) using CAT6 cabling
Both the 1-GbE and 10-GbE NICs configurations will bond the multiple
Ethernet ports into a single interface by default:
• For the 1-GbE NIC, the four ports are bonded together to form one
connection.
• For the 10-GbE NIC, to operate at maximum speed, only the two
high-speed Ethernet ports are bonded together.
You configure the NICs to use either of the two following supported bonding
configurations:
• ALB—adaptive load balancing (ALB) is the default; this configuration
does not require special switch support, but it does require the data
source machine to be on the same subnet as the DR4000 system. The
ALB is mediated by the Address Resolution Protocol (ARP).
802.3ad—also known as Link Aggregation Control Protocol (LACP) is
•
used for copper-wired Ethernet applications; this configuration does
require special switch management (the requirement being that it be
managed from the switch).
For more information, see "Configuring Networking Settings" on page 33.
ALB and the 802.3ad are link aggregation methods that aggregate or combine
multiple network connections in parallel to increase throughput beyond what
a single connection could support.
Link aggregation for Ethernet connections also provides redundancy, in case
one of the links fails. The DR4000 system also comes with a Serial-Attached
SCSI (SAS) card for future enhancements.
