Data protection features include:
- Internal T10-DIF—T10-DIF (Data Integrity Field), or T10-PI (Protection Information), is a standard for data protection that changes the SCSI block from 512 bytes to 520 bytes and adds 8 bytes of protection information such as CRC and block address. Internally, all data within the PowerMax system is protected with T10-DIF as it moves between the front-end modules, cache, back-end, and flash storage. PowerMax T10-DIF protection includes local and remote replications, preventing data corruption.
- External T10-DIF—With supported configurations, the PowerMax storage system allows for T10-DIF protection to extend to the database server and back. The participating layers validate all read and write I/Os in real time and block corruptions. External T10-DIF is implemented by Oracle ASMlib, Red Hat Linux, and others. Consult the Dell EMC support matrix for a full list of supported configurations.
- PowerProtect Storage Direct—PowerProtect Storage Direct (previously called ProtectPoint) is an integration between the PowerMax storage system and the Data Domain backup storage appliance that allows backups of large databases to be performed in seconds. The Data Domain catalogs the backups and adds compression, deduplication, and optional remote replications. Restore time is also optimized in the integrated system.
- D@RE—Data at rest encryption (D@RE) provides transparent data encryption in the storage system. The PowerMax storage system uses specialized hardware modules to avoid performance penalties.
