Upgrading a SAS RAID storage adapter

Find information about upgrading the PCI-X and PCIe SAS RAID storage adapters with PCIe2 or PCIe3 SAS RAID storage adapters.

The PCIe2 and PCIe3 SAS RAID adapters add the industry standard T-10 Data Integrity Fields (DIF) for superior data protection. The T-10 DIF attaches three fields to each data block. During the operation, the DIFs can be checked at different points to detect data corruption or inappropriate use. When upgrading from PCI-X and PCIe SAS RAID storage adapters (which did not utilize the T-10 DIF fields) to PCIe2 or PCIe3 SAS RAID storage adapters, an automatic conversion process is performed to generate the T-10 DIFs on each data block. Once this conversion is performed, the devices are not usable on the previous PCI-X or PCIe SAS RAID storage adapters unless they are reformatted.
