HPE 3PAR StoreServ systems perform Data-at-Rest Encryption at the ASIC (Application-Specific Integrated Circuit) level. This approach ensures that encryption is handled efficiently with minimal impact on performance. The ASIC is responsible for encrypting all data as it is written to the physical disks, providing a secure layer of protection for stored data without compromising the high performance that 3PAR systems are known for.
