Description

The HPE 1.92TB NVMe Gen5 EDSFF E3.S SSD (PM9D3a) is a PCIe Gen5 enterprise solid-state drive in the compact E3.S EC1 form factor, engineered for read-intensive workloads including databases, cloud compute, web servers, and read caching in HPE Gen11 and Gen12 ProLiant, Apollo, and Synergy servers. Delivering higher bandwidth and lower latency than PCIe Gen4, the Samsung PM9D3a drive supports SPDM (Security Protocol and Data Model) for enhanced drive-level security and includes full data-path error detection for data integrity across demanding production environments.

The EDSFF E3.S form factor replaces traditional 2.5-inch SFF SSDs, enabling up to 20 drives per 1U server or 36 drives per 2U server — significantly increasing NVMe storage density without expanding rack footprint. HPE's rigorous qualification process ensures compatibility and reliability standards are met for mission-critical deployments.

FAQs

Q: What servers is the HPE P78914-B21 SSD compatible with?
A: This drive is compatible with HPE Gen11 and Gen12 ProLiant, Apollo, and Synergy servers that support the EDSFF E3.S EC1 drive bay. Always verify your specific server model supports E3.S bays before ordering.

Q: What workloads is this SSD optimised for?
A: The PM9D3a is a Read Intensive (RI) drive, making it best suited for workloads with high read-to-write ratios such as databases, cloud compute, containerised applications, web servers, read caching, and OS boot or swap volumes.

Q: What is EDSFF E3.S and how does it differ from a standard 2.5-inch SSD?
A: EDSFF (Enterprise and Data Centre SSD Form Factor) E3.S is a compact, purpose-built NVMe form factor designed to replace 2.5-inch SFF SSDs. It offers significantly higher drive density — up to 20 per 1U or 36 per 2U — improved thermals, and better power efficiency for high-density NVMe deployments.

Q: What is SPDM support and why does it matter?
A: SPDM (Security Protocol and Data Model) is an industry-standard security framework that provides drive authentication and attestation, helping to verify the integrity of the storage device in the server. This is important for enterprise and government environments where supply chain security is critical.

Q: How does PCIe Gen5 NVMe compare to PCIe Gen4 for storage performance?
A: PCIe Gen5 doubles the available bandwidth over Gen4, enabling higher sequential throughput and lower latency. For read-intensive enterprise workloads, this translates to faster data access and improved application responsiveness under heavy I/O load.

Q: Can I purchase the HPE P78914-B21 SSD in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller that stocks HPE enterprise storage components including EDSFF E3.S SSDs. Contact us or visit the product page to check availability, pricing, and lead times.
