Consistent Latency and Throughput

Unlike traditional hard drives, this SSD delivers predictable latency and consistent performance even under load. This consistency is critical for enterprise applications that require stable response times and dependable user experiences.

Smart Carrier Technology Advantages

Enhanced Drive Management

The Smart Carrier (SC) design integrates status LEDs and intelligent monitoring features directly into the drive tray. Administrators can quickly identify drive health, activity status, and potential issues without accessing management software.

Hot Plug and Serviceability

The Smart Carrier supports hot plug functionality, allowing drives to be installed or replaced without shutting down the server. This improves uptime and simplifies maintenance in production environments.

Digitally Signed Firmware for Enterprise Security

Protection Against Unauthorized Firmware

HPE Digitally Signed Firmware ensures that only authentic, validated firmware can run on the SSD. This prevents malicious or corrupted firmware from compromising data integrity or system stability.

Trusted Supply Chain Integration

By enforcing firmware authenticity, HPE enhances trust across the hardware lifecycle, from manufacturing to deployment and ongoing updates within enterprise infrastructures.

Compatibility with HPE ProLiant Servers

Support for Gen8, Gen9, and Gen10

The HPE P04478-B21 is fully compatible with HPE ProLiant Gen8, Gen9, and Gen10 servers. This broad compatibility allows organizations to standardize on a single SSD model across multiple server generations.

Seamless Integration with HPE RAID Controllers

The drive works smoothly with HPE Smart Array controllers, ensuring optimal performance, error handling, and monitoring when used in RAID configurations.

Reliability and Endurance

Enterprise Grade Build Quality

Designed for continuous operation in data center environments, the HPE P04478-B21 meets strict enterprise reliability standards. It is validated through extensive testing to ensure stable performance under sustained workloads.

Endurance Suited for Read Intensive Use
