Hardware CRC function for reliable data integrity and error detection across data paths. Supports PCI (Message Signaled Interrupt) and X, enabling efficient interrupt signaling for PCI devices. ECMA393 ProxZzzy standard support for sleeping hosts; includes onLAN and 'RealWow!' technology ( up) for power management and remote wake/management capabilities. Swap//skew correction with detection and automatic correction; includes hardware ECC (Correction Code) support to protect memory and data paths from errors. Use scenarios Enterprise storage and server environments: Ensure data integrity with hardwarebased CRC and ECC, reducing the risk of silent data corruption in storage arrays and critical workloads. The PCI interrupt support helps maintain responsive I/O handling in demand systems. Data center and network appliances: Utilize ProxZzzy sleepinghost compatibility with onLAN and RealWow! technology for efficient power management and remote control, enabling faster wake cycles and streamlined remote administration without sacrificing reliability. Memory and datapath protection in availability systems: Employ swap/skew correction with automatic correction to maintain data alignment and consistency, while hardware ECC provides additional protection against memory errors, supporting continuous operation in uptimesensitive deployments.
