NORCROSS, GEORGIA: – AMI, a global leader in BIOS and UEFI firmware, server and remote management tools, data storage products and unique solutions based on the Linux® and Android™ operating systems, is pleased to announce the support for NVMe® metadata and end-to-end data protection in Aptio® V UEFI BIOS firmware.

The NVMe specification defines how host software interfaces with a non-volatile memory subsystem and also outlines NVMe metadata information for every block on the drive. Each block can be CRC (Cyclical Redundancy Check) protected and CRC is an integral part of the metadata.

AMI, Inc. (AMI) has added support for NVMe metadata in the Aptio V NVMe driver, providing users with the ability for end-to-end data protection. The added support allows storage of a CRC for every block in the metadata section. CRC is sometimes incorporated into the block data of storage devices to verify the data and identify corruption. While blocks are read from the drive, the Aptio V NVMe driver verifies that each block of data matches the CRC. If the data read from the block does not match the CRC, Aptio V NVMe driver will return an error for that block as “corrupted” data. As blocks are written to the drive, the CRC of the blocks is updated accordingly.

By integrating the support for NVMe metadata in the Aptio V NVMe driver, users can expect their data to be protected since data will go through a verification process, ensuring that any corrupted data is identified and fixed. Aptio V support for NVMe drive metadata exists at the pre-OS time frame and requires operating system support to be available at the OS time frame to get complete data protection.
