861590-B21 Use Case
Enterprise Backup & Disaster Recovery with HPE 861590-B21
A mid-sized financial services firm deploys eight HPE 861590-B21 8 TB SAS 12 G Midline HDDs in an HPE ProLiant Gen9 storage array to host nightly full-system backups and offsite replication. By leveraging 12 Gb/s SAS throughput and helium-filled platters, the solution reduces backup windows by 40%, cuts power consumption by 30%, and delivers enterprise-grade reliability with digitally signed firmware to meet stringent RTO/RPO SLAs.
High-Density Virtual Desktop Infrastructure (VDI) Storage
An education provider consolidates 200 VMware Horizon desktops on ProLiant Gen8 servers using HPE 861590-B21 drives in an MSA 2050 SAN. The 8 TB capacity per drive and 7.2 K RPM midline performance ensure smooth login storms and steady IOPS, while helium technology lowers cooling costs. The result: a 50% reduction in storage footprint, consistent user experience under peak load, and simplified management with HPE firmware security.
24/7 Video Surveillance & Compliance Archiving
A retail chain upgrades its IP-camera archive on Gen9 servers with HPE 861590-B21 8 TB SAS HDDs to store high-resolution footage for 90 days. The high-capacity, sequential-optimized design supports continuous write streams, and 512e sector formatting maximizes usable space. Outcome: uninterrupted 24/7 recording, 20% lower rack-level power draw, and full compliance with audit requirements through digitally signed firmware verification.
