6 DD990 Hardware Overview

Storage CapacityTable 2 lists the capacities of the DD990 and DD990 controller with DD Extended Retention software systems. 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: For information about the Data Domain ES30 expansion shelf, see the separate document, EMC Data Domain ES30 Expansion Shelf Hardware Guide.

10 DD990 Hardware Overview

Hardware InterfacesThe hardware interfaces, shown in Figure 2 enable you to connect to the system through a serial console, monitor, and keyboard, or through Ethernet connections.

The four Ethernet interfaces are located near the top left of the rear of the chassis. The top left is labeled eth0a, top right eth0b, bottom left eth0c, and bottom right eth0d. They enable data transfer to the Data Domain system or for administrative access over a network. The Ethernet interfaces are 1000 Base-T Gigabit copper ports with RJ45 connectors that can accept 10/100 Base-T or Gigabit connections.

The two USB ports, VGA port, and serial port are not used during normal operation. They may be used while the system is being serviced.

PCI Cards and Slot AssignmentsTable 6 shows the PCI card slot assignments for the systems. See Figure 2 for a view of the slot positions on the back panel and Figure 3 for a top view.

Slot, Port, and Card Information

• All systems have two 2-GB NVRAM PCIe cards, in slots 3 and 7.

• Each SAS HBA port accepts a miniSAS connector.

• A DD990 system has three SAS cards for third-party storage connectivity. A DD990 controller with DD Extended Retention software system has four such cards.

• Speed: slots 1 and 2 are Gen1, while slots 3-11 are Gen2.

Note: For complete information on PCI cards, slot rules, and related information, refer to the appropriate guides, for example, DD990 PCI Card Replacement or Upgrade. See “Related Documentation” on page 4.

VTL Card Option

The optional VTL feature requires at least one VTL HBA card. A VTL card is a dual-port, 8 Gb Fibre Channel PCIe HBA card. Three FC HBA slots are available to be used.

Ethernet Card Options

The available Ethernet NIC cards are:

• Dual port copper 10 Gbps Ethernet PCI NIC with SFP+ interface for copper direct attach cable.

• Dual port optical 10 Gbps Ethernet PCI NIC with LC connectors for 10GBase-SR multi-mode fiber.

• Dual port optical 1 Gbps Ethernet PCI NIC with LC connectors for 1000Base-SX multi-mode fiber

• Quad port copper 1 Gbps Ethernet PCI NIC with 1000Base-T ports
