Frequently asked questions

What is the actual storage capacity and interface speed of the HP 691026-001?

The HP 691026-001 provides 400GB of usable capacity with a SAS 6Gb/s (750MB/s theoretical maximum) interface. This is an enterprise-grade MLC NAND SSD designed for random-access workloads where throughput consistency matters more than raw sequential speed. Actual performance depends on workload patterns and server configuration.

Which HP ProLiant servers support this SSD?

The 691026-001 is compatible with HP ProLiant G8 and G9 generation servers across BL (blade), DL (rack), ML (tower), and SL (sled) product lines. Supported models include BL420c, BL460c, DL360, DL380, DL580, ML350, and others. Verify your specific server model in HP compatibility matrices before purchase.

What does the Smart Carrier (SC) hot-plug design enable?

The Smart Carrier design allows hot-swapping of the SSD without powering down the server, enabling non-disruptive drive replacement, upgrades, or maintenance. The SC enclosure also provides additional protection and integrates with HP server management tools for automated drive detection and health monitoring.

How does HP SmartSSD Wear Gauge help with drive lifecycle management?

SmartSSD Wear Gauge tracks NAND flash wear patterns and remaining drive lifespan through HP management tools (iLO, Systems Insight Manager). This allows proactive replacement scheduling before capacity degradation, reducing unexpected failures and enabling predictive maintenance in production environments.

What are the power consumption benefits compared to 2.5-inch HDDs?

SSDs consume significantly less power than mechanical drives—no motor spin-up, no seek operations, and lower idle power draw. The 691026-001 reduces data center power consumption and cooling requirements, directly lowering operational costs in large-scale deployments with hundreds of drives.

Is this SSD suitable for mission-critical production workloads?

Yes. The 691026-001 is enterprise-rated with MLC NAND reliability, wear-leveling algorithms, and power-loss protection. It is designed for 24/7 operation in data centers. However, for highest availability, implement RAID configurations and redundant storage paths as part of your overall infrastructure design.

What is the model number and part number relationship?

The part number is 691026-001 (HP SPS/spare part number). The actual drive model is MO0400FBRWC. The option part number is 690827-B21. Always reference the specific part number when ordering to ensure correct drive and tray compatibility with your server generation.
