ECMA393 ProxZzzy standard for sleeping hosts with WakeonLAN and RealWow! remote wakeup. This enables waking systems remotely to perform maintenance or updates, reducing manual intervention and downtime. Hardware (Cyclic Redundancy Check) function. Provides data integrity support at the hardware level to help detect and prevent corrupted data. Swap/sex/skew correction, with detection and automatic correction. Includes hardware ECC (Error Correction Code) for automatic error detection and correction to improve reliability of critical data. PCI support with Message Signaled Interrupt and X. Facilitates flexible interrupt handling and compatibility with PCI systems and configurations. Use scenarios Data center maintenance and orchestration: Wake sleeping servers remotely using WakeonLAN and RealWow! to apply updates or perform health checks without onsite visits, improving maintenance efficiency and reducing operational delays. Enterprise workstation management: Wake desktop clients for scheduled updates, backups, or policy enforcement, while relying on hardware CRC and ECC to safeguard data integrity during critical tasks. Storage and availability environments: Ensure data integrity with hardware CRC and error correction while maintaining compatibility with PCI(X) based expansion cards and peripherals for reliable, scalable deployments.
