The 804405-B21 HPE Smart Array P408E-P 6GB/S SATA / 12GB/S SAS PCIE 3.0 X8 Storage Raid Controller is a host bus adapter (HBA) designed for use with HPE ProLiant servers. It supports RAID 0, 1, 1+0, 5, 6, 10, 50, and 60, which means that it can create different levels of RAID depending on the requirement. It also supports for multiple logical drives and has a maximum of 512 logical drives per controller.
RAID 0, also known as striping, distributes data across multiple disks for increased performance. RAID 1, also known as mirroring, creates a duplicate copy of the data on another disk for data protection. RAID 1+0, also known as mirroring and striping, combines RAID 0 and RAID 1 for increased performance and data protection. RAID 5 uses data striping and parity to provide data protection against a single disk failure. RAID 6 uses data striping and dual parity to provide data protection against two disk failures. RAID 10, also known as mirroring and striping, combines RAID 1 and RAID 0 for increased performance and data protection. RAID 50 and RAID 60 use a combination of data striping and parity to provide data protection against multiple disk failures.
The HPE Smart Array P408E-P also supports advanced data protection features such as Online RAID Level Migration (RLM) and Automatic Data Recovery (ADR) which allows you to move data between RAID levels and recover data automatically in case of a drive failure. It also supports HPE's Advanced Data Mirroring technology, which allows for real-time data replication and disaster recovery.
