Management Integration

When deployed in Dell servers, the drive integrates fully with Dell OpenManage systems management suite, providing comprehensive health monitoring, predictive failure analysis, and simplified firmware updates.

Third-Party Server Compatibility

While optimized for Dell environments, the standard SAS interface ensures compatibility with servers from other manufacturers, though some advanced management features may require vendor-specific tools.

Performance Characteristics

The performance profile of the Dell 400-AXYC is tailored specifically for read-intensive applications while maintaining respectable write capabilities.

Input/Output Operations Per Second (IOPS)

This drive delivers high random read IOPS, enabling it to handle numerous simultaneous data requests efficiently. The specific IOPS performance varies based on workload characteristics but typically exceeds 100,000 random read IOPS.

Sequential Performance

With sequential read speeds approaching the theoretical maximum of the SAS 12Gbps interface, this drive can rapidly transfer large files, stream media, or load substantial datasets into memory.

Latency Profiles

Consistent low latency is a hallmark of this SSD, with typical read latency under 100 microseconds. This predictable performance ensures applications remain responsive even during peak usage periods.

Reliability and Data Protection

Enterprise storage demands exceptional reliability, and the Dell 400-AXYC incorporates multiple technologies to ensure data integrity and availability.

Error Correction and Data Integrity

Advanced error correction algorithms protect against data corruption, while end-to-end data path protection ensures information remains intact from the host interface to the NAND media and back.

Power Loss Protection

Capacitor-based power loss protection circuits safeguard data in transit during unexpected power interruptions, completing writes in progress and preventing data loss or corruption.

Mean Time Between Failures (MTBF)

With an MTBF rating exceeding 2 million hours, this drive demonstrates exceptional reliability for continuous operation in demanding server environments.

Endurance and Warranty

The drive's endurance specifications align with its read-intensive designation, offering sufficient write endurance for its target workloads while maintaining cost-effectiveness.

Total Bytes Written (TBW)

The specified TBW rating indicates the total amount of data that can be written to the drive over its lifetime, with the 400-AXYC providing ample endurance for read-centric applications with moderate write requirements.

Drive Writes Per Day (DWPD)

Expressed as Drive Writes Per Day, this metric indicates how many times the entire drive capacity can be written per day over the warranty period. For read-intensive drives like the 400-AXYC, this typically ranges from 0.5 to 1 DWPD.

Environmental Specifications

Designed for data center deployment, this drive operates reliably within standard server environmental parameters.

Operating Temperature Range

The drive maintains consistent performance across a broad temperature range typical of data center environments, with specific operating parameters detailed in the product specifications.
