EMC Centera Migration Basics
EMC Centera was introduced to the data archiving market in April 2002, and was the first disk-based Write Once Read Many (WORM) storage device based on an algorithm known as content addressed storage (CAS) that assigns a unique identifier to each stored object, rather than using standard CIFS or NFS file systems.
When an application delivers a data object to a Centera, the Centera operating system creates an XML file called a C-Clip, which includes all file metadata (file name, creation date, directory path, etc.) and associates the metadata with the object.
Although Centera has been a leading platform for archiving data to a WORM storage device, the product line is approaching its 13th year in the marketplace, and many earlier generations of Centera hardware have reached end-of-life status, leaving many organizations with no choice but to migrate their data to alternate platforms such as Isilon or VNX – thereby creating a need for data migration for EMC Centera.
To begin planning a data migration effort, organizations need to first understand that an EMC Centera device is not presented as a CIFS or NFS share on a network, so data cannot be simply copied to a new target using methods such as Windows copy-and-paste, DOS xcopy commands or third-party file management utilities.
Our purpose-built EMC Centera migration software utilizes the metadata contained within the Centera C-Clips to convert data objects back to standard files, recreate their original file name, the path to which they were written, and apply any other associated metadata to the files so they become readable again to the application.
To maintain regulatory compliance for laws such as SEC 17a-4 and Sarbanes-Oxley, every step of the migration process is captured and logged, beginning with selecting the source data, and ending with post-migration verification of content on the new system, thereby documenting the chain-of-custody for each file.
Additionally, our software will replicate retention policies applied to objects stored on the Centera over to the new target device, and purge any objects that have exceeded their retention period, further ensuring that regulatory compliance is maintained.
At Data Archive, we understand the value of your data and how important continual access to this information is to the success of your organization, so our goal is to ensure that your information is accurately migrated and that your access requirements are continually met for the duration of the project.
