HPE P77059-B21 7.68TB SSD

The HPE P77059-B21 is a 7.68TB solid state drive for high performance read intensive workloads. It uses an NVMe Gen5 interface and is identified as an E3S EDSFF drive. The product description also identifies EC1, SPDM, and the 9550 SSD family. EDSFF is a data center solid state drive form factor, while SPDM identifies support for the Security Protocol and Data Model. The supplied product information does not specify endurance ratings, sequential performance, random performance, power requirements, or supported HPE server models. Confirm the host platform, EDSFF bay type, firmware requirements, and drive qualification before installation.

The supplied data identifies the drive as an HPE E3S EDSFF model, but it does not list compatible servers, storage systems, controllers, backplanes, or operating system requirements. Installation therefore depends on an HPE platform with a matching E3S EDSFF bay and support for an NVMe Gen5 device. Verify the server documentation and current qualification matrix for the exact P77059-B21 part number. Check that the system supports the 7.68TB capacity and the drive's SPDM and EC1 features. Do not substitute a different EDSFF size or interface without confirming mechanical, electrical, firmware, and software compatibility.
