About the HPE 861742-B21 - HPE 6TB SATA 7.2K LFF LP 512e DS HDD
Designed for 24×7 nearline, sustained sequential, and bulk data workloads, the HPE 861742-B21 is a 6 TB SATA enterprise hard drive engineered for DataStore (DS) server environments. This Large Form Factor 3.5-inch drive spins at 7,200 RPM with a 512e sector configuration and 128 MB buffer, delivering predictable performance for data-intensive applications across HPE ProLiant Gen9 and Gen10 infrastructure. The Low Profile form factor integrates seamlessly into dense server chassis, while hot-plug capability with HPE LFF hot-plug drive carriers enables field replacement without downtime. Storage architects and IT procurement teams benefit from HPE's server-optimized firmware, SmartDrive LED fault identification, and integration with HPE iLO health monitoring and Insight Diagnostics for proactive drive management.
Part number 861742-B21 connects via SATA 6Gb/s interface and operates with HPE Smart Array B-series and P-series SATA/SAS controllers, ensuring compatibility across diverse enterprise deployments. RoHS compliant and backed by HPE's reliability standards, this drive is purpose-built for sustained sequential operations where cost-per-TB and availability matter more than random I/O performance. Whether consolidating nearline archives or supporting bulk sequential reads in data warehousing environments, the HPE 6TB drive delivers enterprise-grade durability and monitoring integration.
