Storage Capacity Table 2: Table 2 lists the capacities of the DD880 and DD880g. Data Domain system internal indexes and other product components use variable amounts of storage, depending on the type of data and the sizes of files. If you send different data sets to otherwise identical systems, one system may, over time, have room for more or less actual backup data than another. Note: Data Domain system commands compute and display amounts of disk space or data as decimal multiples of certain powers of two (2 10, 2 20, 2 30, and so forth). For example, 7 GiB of disk space = 7 x 2 30 bytes = 7 x 1,073,741,824 bytes. Data Domain refers to this process as Base 2 calculation.

Use a ballpoint pen to activate this button. Press to power on the system. Never shut down the system by pressing the Power button. Instead, use the system poweroff command to shut down the system. Lights blue LED front and rear to identify the chassis in a stack. Mutes audible alarm, if active. The front of the control panel contains the following LED indicators, from left to right: Hard Drive Activity LANs 1 and 2 Status Power System ID Blinking green: Drive active Amber: Drive fault Blinking green: Active Steady green: Good Blinking green or amber: Warning Solid amber: Critical error Steady green: power Solid blue: ID button has been pressed DD880 and DD880g Hardware Overview 7
Back Panel Figure 2 shows the hardware features on the back panel. Figure 2: Back Panel A sticker near the Ethernet port connectors (not shown above) shows the system MAC address. The Ethernet ports are named in one of the following ways: eth0 and eth1 (legacy port naming) eth0a and eth0b (slot-based port naming) Ethernet Ports For more information about port mapping, see Ethernet Card Options and Port Naming on page 11. 8 DD880 and DD880g Hardware Overview

A DD880 system can have two or three dual-port Serial Attached SCSI (SAS) HBA PCIe cards for expansion shelf connectivity. DD OS 4.8 supports three SAS HBA cards, but also requires 64 GB of memory to support maximum system capacity. Each SAS HBA port accepts a minisas connector. A DD880g system has two dual-port Fibre Channel PCIe HBA cards for third-party storage connectivity. Each port accepts an LC connector. Both systems have two slots available for optional Ethernet NIC and VTL HBA cards. The optional VTL feature requires at least one VTL HBA card. Depending on your needs, you can leave these slots empty, install two cards of either type, or install one card of each type. DD OS versions 4.7 and 4.8 support 4-Gb Fiber Channel PCIe HBA cards for use as Gateway FC cards and VTL cards. DD OS version 4.9 and later includes support for both 4-Gb Fibre Channel cards and 8-Gb Fibre Channel PCIe HBA cards for use as Gateway FC cards and VTL cards. Note: Mixing 4-Gb and 8-Gb Fiber Channel PCIe cards in the same system is not supported. VTL Card Option The VTL card is a dual-port Fibre Channel PCIe HBA card. 10 DD880 and DD880g Hardware Overview
Ethernet Card Options and Port Naming The available Ethernet NIC cards are: Dual port copper 1 Gb (1000 Base-T) Ethernet PCIe NIC with RJ-45 connectors Dual port optical 1 Gb (1000 Base-SX) multi-mode fiber Ethernet PCIe NIC with LC connectors Dual port copper 10 Gb (10GBase-CX4) Ethernet PCIe NIC with CX4 connectors Single port optical 10 Gb (10GBase-SX) multi-mode fiber (850 nm) Ethernet PCIe NIC with an LC connector Dual-port copper 10-Gb Ethernet PCIe NIC with SFP+ connectors (requires DD OS 4.9 or later) Dual-port optical 10-Gb Ethernet PCIe NIC with LC connectors (requires DD OS 4.9 or later) Note: Two of the same card type can be installed, or a combination of two different card types. Certain restrictions apply to combinations of the 10-Gb Ethernet cards in a system. The following combinations are supported: Dual-port copper 10-Gb Ethernet card with SFP+ connectors plus Dual-port optical 10-Gb Ethernet card with LC connectors Both cards require DD OS 4.9 or later. Dual-port copper 10-Gb Ethernet card with CX4 connectors plus Single-port optical 10-Gb (10GBase-SX) Ethernet card with an LC connector. Other combinations of 10-Gb Ethernet cards are not supported. The Ethernet ports on the system motherboard are named in one of the following ways: eth0 and eth1 (legacy port naming) eth0a and eth0b (slot-based port naming) Legacy port naming is used on systems that are running DD OS 4.8 and earlier software versions. In addition, systems that are upgraded to DD OS 4.9 will continue to use legacy port naming unless you explicitly configure slot-based port naming after the software upgrade. Slot-based port naming occurs by default in systems with a fresh installation of DD OS 4.9, or in new systems that are shipped with DD OS 4.9 installed. With slot-based port naming, the Ethernet ports on installed optional Ethernet cards are identified by a combination of their slot number and port letter. The first port in a slot (at the top) is labeled a and the second port is b. For example, a dual-port copper card in Slot 5 has the Ethernet port names eth5a and eth5b.see the Network Management chapter in the Data Domain Operating System Administration Guide for help configuring the Ethernet interfaces for failover and aggregation.
