Features of HPE P21135-B21 SSD

Enterprise-Grade Performance

This drive offers SAS-12GBPS interface speed, ensuring rapid data transfer rates that can handle demanding enterprise applications, including database management, virtualization, and large-scale analytics. Its architecture supports high Input/Output Operations Per Second (IOPS), providing consistent performance even under heavy workloads.

Mixed-Use Workload

Unlike read-centric SSDs, the HPE P21135-B21 is engineered for mixed-use workloads, where both read and write operations are significant. This versatility ensures balanced performance in environments such as OLTP (Online Transaction Processing), virtualization clusters, and application servers, where the ratio of read/write operations varies.

Advanced Reliability and Endurance

HPE P21135-B21 SSDs are built with advanced NAND flash memory that provides superior endurance for mixed-use environments. Features like power loss protection, end-to-end data path protection, and error correction algorithms ensure data integrity and drive longevity.

Hot-Swap and Small Form Factor Benefits

The SFF hot-swap design allows administrators to replace or upgrade drives without shutting down servers, minimizing downtime and maintaining service continuity. Its 2.5-inch form factor ensures compatibility with HPE ProLiant and Synergy servers, providing a versatile storage option in space-constrained data centers.

Hot-Swap

Hot-swapping simplifies drive maintenance, reduces operational disruption, and ensures high availability. IT teams can quickly replace failed drives or upgrade storage capacity without impacting critical workloads.

Server Ecosystem

These SSDs are validated for high compatibility across HPE servers, guaranteeing reliable operation, firmware updates, and firmware consistency. They support RAID configurations, enabling redundancy, improved performance, and data protection strategies tailored to enterprise environments.

Storage Capacity

With a massive 3.2TB storage capacity, the HPE P21135-B21 can store large datasets, virtual machine images, databases, and other enterprise workloads. This capacity is ideal for organizations looking to consolidate storage while maintaining high-performance access.

Endurance and Reliability

The mixed-use SSD is rated for a high number of drive writes per day (DWPD), supporting thousands of write cycles without degradation. Combined with features like power loss protection and ECC, it ensures long-term data integrity and predictable performance in mission-critical environments.

High-Performance Computing (HPC)

In HPC environments, where computational workloads generate significant read/write demands, the HPE P21135-B21 provides the throughput and endurance needed to maintain high-speed operations. Applications like simulations, modeling, and data analytics gain from consistent low-latency performance.
