HPE 849475-001 400GB SAS 12GBPS LFF MU Hot-Pluggable SSD

The HPE 849475-001 400GB SAS 12Gbps 3.5 inch LFF Mixed-Use (MU) hot-pluggable solid state drive is engineered for enterprise-class storage environments that demand consistent throughput, low latency, and high reliability. Designed as a Large Form Factor (LFF) 3.5-inch SAS drive with a 12Gbps interface, this 400GB Mixed-Use SSD combines enterprise-level endurance and performance characteristics with hot-pluggable convenience to support modern server and storage array workloads. The drive is optimized for mixed-use applications that require a balance between read and write operations, making it ideal for virtualization hosts, database workloads, caching layers, and mixed enterprise applications where predictable performance is paramount.

Key technical characteristics and enterprise readiness

At its core, the HPE 849475-001 offers a SAS 12Gbps interface, which ensures high-bandwidth connectivity to HPE ProLiant servers and HPE storage platforms that support SAS connectivity. The 3.5-inch LFF form factor provides compatibility with chassis designed for LFF drives, while the hot-pluggable design simplifies maintenance and reduces downtime by enabling drive replacement without powering down systems. With a 400GB capacity tuned for enterprise mixed-use workloads, the drive balances capacity and endurance to deliver long-term value in production environments. Enterprise-grade features such as power-loss protection, error correction mechanisms, and robust thermal management contribute to the drive’s reliability under sustained workloads.

Performance profile: throughput, IOPS, and latency

This Mixed-Use SSD delivers consistent random and sequential performance across a wide range of block sizes and queue depths, which is vital for supporting both transactional and throughput-oriented workloads. Enterprise administrators can expect strong IOPS for mixed read/write patterns, with low and predictable latency that keeps application response times fast even during peak load. The 12Gbps SAS interface removes bandwidth constraints that might throttle performance for demanding workloads, and the internal controller and NAND architecture are tuned to prioritize consistent quality-of-service rather than transient peak bursts that degrade performance under sustained writes. In practical deployments, this translates into smoother virtual machine behavior, faster database queries, and more reliable caching performance.

Endurance and data integrity

The endurance rating of an enterprise-class Mixed-Use drive like the HPE 849475-001 is calibrated to support daily write cycles common in mixed workloads. This drive is built with enterprise-grade NAND, comprehensive wear-leveling algorithms, and advanced error correction to extend usable life and maintain data integrity. Additional safeguards such as power-loss protection capacitors protect in-flight data, reducing the risk of corruption during unexpected power events. For organizations that prioritize long-term data reliability, the combination of engineered endurance and on-drive integrity features helps reduce the frequency of replacements and supports predictable storage planning.

Compatibility and integration with HPE systems

One of the practical advantages of choosing the HPE 849475-001 is seamless compatibility with a broad set of HPE hardware and firmware ecosystems. The drive is designed to work within HPE ProLiant server families, HPE storage enclosures that accept 3.5-inch SAS drives, and HPE Smart Array controllers that support SAS 12Gbps speeds. Firmware-level compatibility ensures that drive health monitoring, predictive failure alerts, and SMART telemetry integrate with HPE management tools, enabling administrators to view drive metrics and perform proactive maintenance from centralized platforms. When integrated properly, the drive’s native telemetry can be used to automate replacement workflows and schedule capacity upgrades with minimal operational friction.

Form factor and physical considerations

The Large Form Factor (3.5-inch) design of this HPE SSD offers advantages for certain rack and storage configurations. LFF drives typically provide more physical capacity per bay, which can simplify rack layout when fewer but larger drives are preferred. The hot-pluggable tray or carrier designs used by HPE reduce the risk of handling damage during swap operations and provide the mechanical compatibility necessary for enterprise hot-swap systems. Thermal considerations should be accounted for during deployment: adequate airflow within server chassis and storage enclosures is required to maintain optimal operating temperatures and sustain performance under heavy workloads.

Typical use cases and workload suitability

The HPE 849475-001 400GB MU SSD is particularly well-suited for mixed-use workloads where the balance of reads and writes is essential. Typical use cases include virtualization hosts running multiple virtual machines and containerized workloads, SQL and NoSQL databases with variable access patterns, email servers, and combined caching and tiering strategies where SSDs act as accelerated tiers in a hybrid storage architecture. The drive’s endurance characteristics also make it appropriate for moderate logging and analytics workloads that generate frequent writes but still require durable storage. In caching and tiering deployments, using this Mixed-Use drive as a cache layer can significantly reduce latency for frequently accessed data while prolonging the life and capacity efficiency of backend HDD tiers.

Enterprise storage architectures: tiering and hybrid arrays

In hybrid storage arrays, the HPE 849475-001 can serve as an accelerated tier that absorbs hot data, enabling the array to deliver performance closer to all-flash systems at a reduced cost per gigabyte. Tiering policies can be configured to automatically migrate frequently accessed blocks to the Mixed-Use SSD tier while colder data remains on high-capacity HDDs. This approach maximizes return on investment by improving application performance without requiring an all-flash footprint. The drive’s 12Gbps SAS interface allows it to keep pace with backend controllers and deliver consistent throughput across tiered operations.

Deployment best practices

To get the most from the HPE 849475-001, follow proven deployment practices. Ensure firmware is up-to-date for both the drive and the host controller to take advantage of reliability and performance improvements. Match the drive to compatible HPE controllers and enclosures to preserve management and telemetry features. Implement RAID configurations that balance performance and redundancy according to workload requirements; Mixed-Use SSDs are commonly used in RAID 10 for mixed transactional workloads where both performance and redundancy are required. Monitor SMART attributes and drive health using HPE’s management tools and set up alerts for early indication of issues so that hot-swap replacements can be scheduled as needed without unexpected downtime.

Thermal and power considerations

Because SSDs can sustain high throughput, they also dissipate heat that must be managed by the server or storage enclosure’s cooling system. Adequate airflow across drive bays is essential to avoid thermal throttling that could limit sustained performance. The HPE 849475-001 is designed to operate within enterprise thermal thresholds, but administrators should verify ambient temperatures and ensure fans and vents are unobstructed. Power-loss protection features reduce the risk of data loss, but drives should still be used with uninterruptible power supplies in environments where power stability is a concern, further protecting the storage stack and associated hardware.
