Summary:Storage applications benefit from a set of new PCI Express features associated with RAS. Reliability has been enhanced in PCI Express by way of error detection and signal integrity. PCI Express supports two levels of Error Correction Codes (ECC) checking for both Data Link Layer and Transaction. Layer errors. Error reporting has been expanded as well. Signal integrity is improved by utilizing differential pairs for signal lines with greater noise immunity than a fast speed parallel bus.
