Key Specifications

SAS 12Gbps Interface

Featuring a Serial Attached SCSI (SAS) interface operating at 12 gigabits per second, the Dell 400-BPSF delivers double the bandwidth of previous generation 6Gbps SAS drives. This high-speed interface enables faster data transfer rates, reduced latency, and improved overall system responsiveness. The SAS architecture supports full duplex operation, allowing simultaneous read and write operations, which is critical for multi-user environments and applications requiring high I/O throughput.

Dual-Port Capability

The SAS interface includes dual-port functionality, providing redundant pathways to the storage device. This enterprise-critical feature ensures continuous data availability even if one host bus adapter or connection path fails. Dual-port SAS is essential for high-availability configurations, clustered environments, and mission-critical applications where downtime is not an option.

Rotational Speed and Performance

7200 RPM Spindle Speed

Operating at 7200 revolutions per minute, this drive balances performance, capacity, and power consumption effectively. The 7200 RPM speed provides responsive performance for sequential and random access patterns while maintaining reasonable power and thermal characteristics compared to higher-RPM alternatives. This makes the drive suitable for a wide range of enterprise workloads including file storage, backup targets, and content repositories.

Sustained Data Transfer Rates

The Dell 400-BPSF delivers sustained data transfer rates optimized for its capacity class, ensuring efficient movement of large datasets. The combination of high areal density, advanced caching algorithms, and the 12Gbps SAS interface enables the drive to maintain consistent performance under heavy workloads, minimizing bottlenecks in storage subsystems.

Capacity and Form Factor

Massive 22TB Storage Capacity

With 22 terabytes of raw storage capacity, this drive represents one of the highest capacity points available in the 3.5-inch form factor. This extreme density allows organizations to maximize storage within limited physical space, reducing data center footprint and associated costs. The high capacity makes the drive ideal for scale-out storage architectures, big data analytics, and archival applications where storage density is a primary concern.

512e Advanced Format

The drive employs 512e (512-byte emulation) sector formatting, which uses 4K physical sectors while maintaining compatibility with legacy systems expecting 512-byte sectors. This advanced format technology improves error correction capabilities, increases areal density, and enhances data integrity. The emulation layer ensures broad compatibility with existing infrastructure while delivering the benefits of modern sector architecture.

Hot-Swap Capability

Designed in the industry-standard 3.5-inch hot-plug form factor, the Dell 400-BPSF enables maintenance and expansion without system downtime. The hot-plug design allows administrators to replace failed drives or add capacity while the system remains operational, ensuring continuous availability for critical business applications. This feature is essential for enterprise environments requiring 24/7 operation.

Physical Dimensions

The drive conforms to standard 3.5-inch hard drive dimensions, ensuring compatibility with Dell PowerEdge servers, Dell Storage arrays, and industry-standard server chassis and storage enclosures. The physical design includes appropriate mounting holes, connector placement, and form factor specifications to guarantee proper fit and function in supported systems.

Advanced Cache Technology

High-Speed DRAM Cache

The integrated 512-megabyte DDR SDRAM cache serves as a high-speed buffer between the drive's mechanical components and the host interface. This substantial cache size helps to improve performance by caching frequently accessed data, optimizing write operations, and prefetching data likely to be requested. The large cache is particularly beneficial for workloads with mixed read/write patterns and random access characteristics.

Intelligent Caching Algorithms

Advanced caching algorithms manage the 512MB buffer to maximize performance across various workload types. These algorithms include adaptive read-ahead for sequential access patterns, write caching with protection mechanisms, and intelligent data placement strategies. The cache management system is tuned for enterprise workloads to deliver consistent performance under diverse operating conditions.

Advanced Error Correction

Sophisticated error correction codes (ECC) protect data integrity by detecting and correcting errors that may occur during read and write operations. The drive employs multi-level ECC algorithms capable of correcting both single-bit and multi-bit errors, providing robust protection against data corruption. This advanced error correction is essential for maintaining data integrity in large-scale storage systems.

Power Characteristics

Power Consumption Profiles

The Dell 400-BPSF implements power management features to optimize energy usage across different operational states. Typical power consumption during active operation, idle states, and standby modes are engineered to balance performance requirements with energy efficiency. These power characteristics help data center operators manage overall power consumption and thermal output while maintaining storage performance.

Efficiency Technologies

Advanced power management technologies include multiple power states that automatically adjust based on workload demands. These features reduce energy consumption during periods of low activity without compromising responsiveness when I/O requests resume. The efficiency optimizations contribute to lower operating costs and reduced environmental impact in large-scale deployments.

Dell PowerEdge Server Compatibility

The 400-BPSF is validated for use in Dell PowerEdge servers across multiple generations and models. This compatibility ensures optimal performance, management integration, and firmware compatibility when deployed in Dell server environments. The drive is recognized and supported by Dell system management tools, including iDRAC and OpenManage, providing comprehensive monitoring and management capabilities.
