EMC - DataDomain - Hardware Overview

1. Overview

Data Domain systems are
based around the same basic hardware architecture. Documents for each hardware model are published on the Data Domain support site. Hardware features common to all models include: rack mountable in four-post racks; hot-swappable disks with redundant hot-swappable fans and redundant hot-swappable power modules; serial port and copper Ethernet ports; DIMM modules for RAM; a battery backed NVRAM card; video, keyboard, and mouse ports to connect to a monitor and keyboard and mouse; front panel LEDs that provide system status indicators.

Components under high mechanical or electrical stress such as spinning drives, fans, and power supplies are provided with N+1 redundant configuration, N+1 redundancy is a system configuration in which certain components have at least one independent backup component to ensure system functionality continues if a part fails. This allows for uninterrupted operation at full capacity and operational status if one component fails. For data, RAID 6 technology provides additional protection of data integrity when up to two disks fail

Data Domain systems may be connected to Ethernet networks for TCP/IP-based data transfer and system management. All models have two built-in ports. Some models may be configured with additional ports by adding optional Ethernet expansion cards. Newer systems also include a dedicated Ethernet port for what is known as lights out management or remote system management. Interface cards are usually added to provide additional network capacity.

Connecting to a Fibre Channel-based storage area network is supported by adding a host bus adapter card. In these environments the virtual tape library VTL software license is also required

For repairs in the field, access to the command line interface to shut down restart and run diagnostics is usually through the serial port. The username for the built-in administrator is sysadmin.

The DD990 and older models provide keyboard and PS2 mouse port for connecting directly to the unit with a keyboard and monitor. Check with the onsite administrator for the preferred access method

The majority of Data Domain system models support the expansion of storage with the addition of expansion shelves. There are three different generations of expansion shelves to consider. These three models are still active in existing and new systems: the ES20, the first generation of the ES30 with SATA drives, and a second generation ES30 with SAS drives. The two different ES30 drive types cannot be mixed in a shelf.
The two different ES30 drives are distinguished only with drive labels. Note that the ES30 SATA shelf label can indicate up to 2 TB, while the ES30 SAS shelf label can indicate up to 3 TB

The 3U Data Domain ES20 expansion shelf has 16 disks for increased storage capacity of certain
models. The expansion shelf fits in a standard 19-inch rack and connects to either a Data Domain
system or to another expansion shelf.

DD7200

The DD7200 enables users to backup 208 TB in under 8 hours with up to 26 TB/hr aggregate ingest performance with DD Boost. The base of this scalable system supports up to 18 expansion shelves of 2 TB or up to 12 expansion shelves of 3 TB, which enables customers to protect up to 21.4 PB logical and 428 TB usable capacity in a single namespace – this includes support for both 2TB and the new 3TB ES30 expansion shelves with these conditions:

• New orders ‐ Factory ships only ES30 SAS Shelves, with 2TB or 3TB HDDs

• DD7200 also supports legacy ES20 and ES30 SATA Shelves

• SAS and SATA shelves cannot be mixed on the same set

With the Data Domain Extended Retention software option, this scalable system can support up to 56 expansion shelves, which enables customers to protect up to 85.6 PB logical and 1.7 PB usable capacity for long-term backup retention. In addition, the DD7200 can be the target for up to 540 backup streams, enabling consolidation from up to remote sites or the ability to emulate up to virtual tape drives on a single system.

DD2500

The DD2500 enables users to backup 175 TB in under 8 hours with up to 13.4 TB/hr aggregate ingest performance with DD Boost. The DD2500 has two capacity configurations:

• 7 x 3 TB HDDs, ~11.2 TB usable

• 12 x 3 TB HDDs, ~25.9 TB usable
