The HPE P49049-K21 1.6TB DS SFF SAS-24GBPS BC MU SSD

The HPE P49049-K21 1.6TB DS SFF SAS-24GBPS BC Mixed Use G10+ SSD represents Hewlett Packard Enterprise’s advanced generation of enterprise-grade solid-state drives designed for performance-intensive workloads. As part of the HPE G10+ storage ecosystem, this SSD provides robust reliability, high-speed data throughput, and consistent low latency across business-critical applications. It belongs to the Mixed Use (MU) category, balancing read and write endurance for environments where both operations are essential.

Featuring a 24Gbps SAS interface and Small Form Factor (SFF) design, this HPE drive enables data centers, enterprises, and cloud infrastructures to maximize efficiency and scalability. It is ideal for servers running virtualized workloads, transaction-heavy databases, analytics, and cloud storage services.

Enterprise Storage and SAS SSD Technology

The HPE P49049-K21 SSD belongs to the class of Serial Attached SCSI (SAS) Solid State Drives, which are engineered for reliability and sustained performance in data-intensive environments. Unlike SATA-based SSDs, SAS drives such as this HPE 1.6TB unit deliver dual-port connectivity, better data integrity, and high availability. These qualities are critical for modern HPE ProLiant Gen10 and Gen10 Plus servers, where uptime and throughput directly affect business continuity.

The Mixed Use (MU) SSD Category

HPE classifies its enterprise SSDs into Read Intensive (RI), Write Intensive (WI), and Mixed Use (MU) categories. The HPE P49049-K21 falls into the Mixed Use segment, designed to sustain both frequent reads and moderate writes. This balance makes it versatile for diverse enterprise tasks like online transaction processing (OLTP), database management, and virtualization platforms.

Endurance and Performance

Mixed Use SSDs are rated for endurance measured in Drive Writes Per Day (DWPD). The P49049-K21 typically supports multiple DWPD values depending on workload patterns, ensuring long operational life even under heavy 24/7 utilization. It combines endurance and speed in a single compact drive, reducing the need for separate storage tiers.

HPE ProLiant Gen10+ Compatibility and Integration

This SSD is designed and validated by HPE to integrate seamlessly with the ProLiant Gen10 and Gen10+ server families. Compatibility ensures full support from HPE’s Smart Array Controllers and firmware ecosystem, delivering a plug-and-play experience for IT administrators.

Smart Array Controller Optimization

When paired with HPE Smart Array Controllers, such as the P408i-a or E208i-p, the SSD benefits from advanced caching, RAID configurations, and automated monitoring tools. The HPE controller firmware optimizes I/O paths, improving both throughput and reliability under mixed workloads.

HPE Smart Carrier Design (BC – Basic Carrier)

The "BC" in the product title refers to the Basic Carrier option, a hot-pluggable design allowing fast installation or replacement without server downtime. Each drive includes status LEDs for quick health checks, simplifying IT maintenance and system monitoring.

Benefits of HPE Mixed Use SAS SSDs

Deploying the HPE P49049-K21 SSD offers multiple operational and business advantages. Beyond simple data storage, it provides speed, reliability, and flexibility essential for today’s hybrid data center environments.

Reliable Data Protection

Enterprise users rely on the robust data integrity features built into every HPE enterprise SSD. Features like power-loss protection (PLP) and end-to-end data path protection safeguard mission-critical data. These mechanisms prevent corruption in case of unexpected power interruptions or controller errors.

Databases and Transactional Workloads

In database-driven environments like Oracle, SQL Server, or SAP HANA, the SSD ensures quick query responses and reliable transaction processing. Businesses can handle real-time analytics, batch processing, and transactional data more efficiently.

Performance Reliability

Enterprise SSDs like the HPE P49049-K21 are designed to deliver consistent performance throughout their lifespan. The drive maintains high reliability metrics such as Mean Time Between Failures (MTBF) and low Unrecoverable Bit Error Rate (UBER). These metrics guarantee dependable service for years under continuous workloads.

Comparing the HPE P49049-K21 to Other Enterprise SSDs

Within HPE’s product range, the P49049-K21 occupies a balanced position between read-intensive and write-intensive options. Its 1.6TB capacity provides a perfect midpoint for performance, endurance, and cost-effectiveness.

Advantages Over Read Intensive SSDs

While Read Intensive (RI) SSDs offer cost advantages for read-heavy workloads, they typically feature lower endurance. The P49049-K21’s Mixed Use design provides greater durability, ensuring stable performance for environments with both reads and writes.

Advantages Over Write Intensive SSDs

Compared to Write Intensive (WI) drives, the P49049-K21 offers an optimized balance at a lower price point, making it ideal for general-purpose enterprise storage. It handles frequent transactional writes while avoiding the higher costs associated with maximum endurance models.

Scalability in Data Center Environments

Organizations can deploy multiple P49049-K21 drives in RAID arrays or storage clusters to achieve higher aggregate capacity and IOPS. Thanks to 24Gbps SAS connectivity, scaling storage infrastructure becomes seamless without saturating the interface bandwidth.

Future-Proofing Enterprise

Investing in 24Gbps SAS-based drives like the HPE P49049-K21 ensures compatibility with the next generation of enterprise hardware. As applications demand more bandwidth and faster storage tiers, this SSD provides a solid foundation for expansion.

Environmental and Operational Efficiency

Sustainability is a growing focus in IT operations, and the HPE P49049-K21 contributes to greener data center initiatives by offering superior performance-per-watt. Its efficient power profile reduces cooling requirements and operational costs, aligning with corporate sustainability goals.

Deployment Flexibility in Enterprise Environments

The HPE P49049-K21 1.6TB SSD integrates seamlessly into multiple deployment models, from on-premise data centers to hybrid and private clouds. Its SAS interface ensures compatibility with existing backplanes, while its small form factor enables higher density in rack-mounted systems.

Integration with Modern Data Center Workflows

Beyond raw performance, the HPE P49049-K21 SSD contributes to the modernization of enterprise storage workflows by supporting automation, virtualization, and data protection tools.
