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 DR Series system also comes with a Serial-Attached SCSI (SAS) card for future enhancements. The DR Series system ships equipped with the 1-GbE, I-GbE, or 10-GbE SFP+ NIC. To visually differentiate between the NIC types, observe the markings on the NICs installed in the rear chassis of the DR Series system: • 1-GbE NIC is labeled as GRN=10 ORN=100 YEL=1000 • 10-GbE NIC is labeled as 10G=GRN 1G=YLW NOTE: There are two key requirements to meet if you use the 10-GbE NIC configuration: 1) use only CAT6a copper cabling, and 2) you must have two switch ports capable of supporting 10-GbE NICs. NOTE: There are two key requirements to meet if you use the 10-GbE SFP+ NIC configuration: 1) use only Dellsupported SFP+ transceivers, and 2) you must have two switch ports capable of supporting 10-GbE SFP+ NICs (and LC fiber-optic or twin-axial cabling). To verify the types of NICs that are installed in your system, click System Configuration → Networking to display the NIC information. For more information, see Configuring Networking Settings. In addition, you can also use the DR Series system CLI network --show command to display other NIC-related information. Monitoring System Usage To display the current DR Series system usage, click Dashboard → Usage to display the Usage page. This page allows you to monitor system status and the currently displayed system usage status is based on the Latest Range or Time Range settings that are in effect. These settings define the output for the following tab categories on the Usage page: • CPU Load • System • Memory • Active Processes • Protocols • Network • Disk • All (displays all system status categories) Displaying Current System Usage To display the current usage for a DR Series system, complete the following: 1. Click Dashboard → Usage. The Usage page is displayed. 2. View the current system usage based on the current Latest Range or Time Range values in effect (the default is the last 1-hour period). By default, the CPU Load is always the first tab that displays when the Usage page is selected. The tabs you can display in the Usage page include: CPU Load, System, Memory, Active Processes, Protocols, Network, Disk, and All. 3. Click any of the system usage tabs to display the current status for that tab category (or click All to display all of the system usage tab results). For example, click Protocols to display the current results for the NFS Usage - Total, CIFS Usage - Total, and RDA Usage - Total for the system. 84

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 DR Series system
also comes with a Serial-Attached SCSI (SAS) card for future enhancements.
The DR Series system ships equipped with the 1-GbE, I-GbE, or 10-GbE SFP+ NIC. To visually differentiate between the
NIC types, observe the markings on the NICs installed in the rear chassis of the DR Series system:
•
1-GbE NIC is labeled as GRN=10 ORN=100 YEL=1000
•
10-GbE NIC is labeled as 10G=GRN 1G=YLW
NOTE:
There are two key requirements to meet if you use the 10-GbE NIC configuration: 1) use only CAT6a copper
cabling, and 2) you must have two switch ports capable of supporting 10-GbE NICs.
NOTE:
There are two key requirements to meet if you use the 10-GbE SFP+ NIC configuration: 1) use only Dell-
supported SFP+ transceivers, and 2) you must have two switch ports capable of supporting 10-GbE SFP+ NICs
(and LC fiber-optic or twin-axial cabling).
To verify the types of NICs that are installed in your system, click
System Configuration
→
Networking
to display the NIC
information. For more information, see
Configuring Networking Settings
. In addition, you can also use the DR Series
system CLI
network --show
command to display other NIC-related information.
Monitoring System Usage
