What is Data Domain Storage?

What is Data Domain storage? Data domain storage is a system that removes redundant linear data. Also, Domain storage takes advantage of high speed in backup, archiving, and recovery. Data Domain Storage easily integrates with existing infrastructure and third-party backup solutions to provide you with your own user experience.

Domain data storage

Data Domain Storage uses variable-length deduplication, which takes a smarter approach to storage and varies the size of storage chunks when looking for common data points. Data domain storage uses data to look at this information and divide it into pieces or sections. Each piece or segment has a hash or identifier known as unique or duplicate data.

Domain data storage by breaking this information into different parts, their hash or ID can be identified and referred to as previously stored data through its table. Incoming data is identified and defragmented inline, and only unique data is sent to disk, which significantly reduces the amount of data on disk. Its next task is recovery, which is known as non-repudiable data architecture or DIA.

Data Domain Storage with DIA functionality creates an end-to-end verification, prevents blocking, detects existing errors, then provides a fault-free file system upon detection.

Data Domain storage takes advantage footprint reduction and makes this possible. The storage saves the risks of data risk and content compromise by using container logs so that the storage will ensure that new data does not cause new data to be compromised. Domain data storage with DIA functionality will ensure that data logging never overwrites or updates existing data, and new data is always written to new sectors. This data domain caching functionality ensures that old sections and references remain in place.

Another task of the data domain storage is replication, which will make the WAN work.

Types of replication in Data Domain storage

Inline deduplication allows replication to run even when backups are in use, allowing for faster disaster recovery. This process reduces backup envelope printing and duplicates printing by sending new chunks of data to the disaster recovery site.
Types of repetition:

  • Repetition of a set: mirror copy or mirrored copy
  • Directory Replication: multiple or selected directories
  • pool replication: replication of VTL pools (virtual tape libraries)

Data Domain Storage provides customers an in-house backup solution, allowing even more robust optimization. It also allows you to restore data faster than tape backups. It also allows efficient delivery of this data to disaster recovery locations by sending fewer data segments from Provides via wire.

As a former OEM support engineer, I have been in this storage department since 2008. I am eager to continue working with Park Place Technologies on data domain storage. Since joining the company, I have understood customers’ ongoing needs who still love and appreciate Data Domain Storage. Customer support is my priority in this work.

In the discussion of data management and the basis of data analysis, data domain storage refers to everything that an element of data includes. A domain boundary rule may be a data type with a list of specified values.

An example of a database table

For example, a database table that has information about people, with one field for each person, may also have a gender column. This gender column may be defined as a string data type, this column is allowed to have one of two known code values: M for male and F for female. Of course, NULL should also be added for files whose gender is unknown or not in these two categories.

The reference range in a normal data model is typically specified in a reference table, as in the previous example. A gender reference table has exactly two things to record that are allowed to record at any value, except for files whose gender is unknown. Reference tables are related to other database tables using foreign keys.

The domain boundary rules and protocols are less simple if the database is implemented. They may be executed through a check constraint or in more complex cases in a database trigger. For example, a column that requires positive numeric values ​​may have a check constraint stating that the values ​​must be greater than zero.

This definition combines the concepts of the domain as an area over which control is applied and the mathematical idea of ​​a set of values ​​of an independent variable for which a function is defined. See: Data Domain Storage (Math)

Initially, an independent company named EMC acquired Data Domain storage in 2009. In the last two years, this company was bought by Dell. Both properties have added to the breadth and enterprise features of Data Domain’s backup and storage protection tools. Dell Technology Company is an independent company in Round Rock, Texas. Dell EMC serves around 180 countries with a portfolio from the edge to the processing core.

Description of this company’s product or data domain storage

Data Domain storage for backup protection, archiving, long-term cloud storage, and recovery in a modern way will allow you to protect against data loss. As mentioned above, this Data Domain storage uses deduplication technology. Uses and this technology provides this function to the storage device, increasing backup speed by 50%. In addition to providing a lower cost of protection by reducing storage requirements, the amount of network usage by about It reduces by 98%.

This design protects the data integrity of data integration with inline data validation, continuous error detection, and self-healing. The data domain supports a wide ecosystem of enterprise and home applications.

You can replicate managed files using this storage. You can keep the images backed up in the data domain storage system for the purposes you need to restore. The gpmfr tool manages the backup sets of the Greenplum Database located on the primary and remote Data Domain Storage systems. For information about this tool, see the Greenplum database manual.

As a replication network is used between two Data Domain storage systems, managed file replication requires network configuration:

Greenplum Database requires data domain login credentials using configured gpcrondump. Credentials must be established for the local and remote systems of the data domain storage.

When unmanaged network interfaces are used for replication across Data Domain storage systems, static routes must be configured on the systems to route replication data traffic to the correct interfaces.
