Administrator Guide

The DR Series system supports configuring 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 DR Series 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.
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
注: There are three key requirements to meet if you choose to use the 10-GbE NIC configuration: 1) use only CAT6a
copper cabling, 2) you must have two switch ports capable of supporting 10-GbE NICs, and 3) you do not connect
the 1-GbE ports.
注: There are three key requirements to meet if you choose to use the 10-GbE SFP+ NIC configuration: 1) use only
Dell-supported SFP+ transceivers, 2) you must have two switch ports capable of supporting 10-GbE SFP+ NICs (and
LC fiber-optic or twin-axial cabling), and 3) you do not connect the 1-GbE ports.
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.
监测系统使用情况
要显示当前 DR Series 系统的使用情况，请单击 Dashboard（仪表板）→ Usage（使用情况）以显示 Usage（使
用情况）页面。通过此页面可监测系统状态，当前显示的系统使用情况状态基于有效的 Latest Range（最后范
围）或 Time Range（时间范围）。这些设置可定义 Usage（使用情况）页面上以下选项卡类别的输出：
• CPU Load（CPU 负载）
• System（系统）
• Memory（内存）
• Active Processes（活动进程）
• Protocols（协议）
• Network（网络）
• Disk（磁盘）
• All（全部）
