793683-B21 Use Case
Cold Data Archiving in Enterprise Data Centers
Scenario: A global research institution consolidates petabytes of infrequently accessed data for compliance and analytics. By deploying HPE 793683-B21 6TB SATA 6G Midline 7.2K LFF (3.5in) SC 1yr Warranty Helium 512e HDDs in archive tiers, IT teams achieve high-capacity storage with helium‐sealing that lowers power consumption by up to 25% per TB. Benefit: Reduced total cost of ownership through energy‐efficient, high‐reliability drives (2.3M-hour MTBF), delivering cost-effective long-term retention and simplified capacity scaling.
High-Definition Surveillance Video Storage
Scenario: A city transit authority installs 4K IP cameras across 500 stations, generating over 20 TB/day of continuous video streams. Integrating HPE 6TB SATA 6G Midline 7.2K LFF Helium 512e HDDs in network video recorders ensures sustained sequential write performance (up to 180 MB/s) and enterprise‐grade reliability under 24×7 workloads. Benefit: Guaranteed 30-day retention with fewer dropped frames, a 40% smaller rack footprint compared to traditional drives, and peace of mind backed by a 1-year warranty.
SMB Virtualization and Backup Acceleration
Scenario: A mid-sized professional services firm hosts VMware and Hyper-V virtual machines alongside critical SQL databases, requiring daily image-level backups within tight maintenance windows. Deploying HPE 793683-B21 HDDs in HPE ProLiant servers boosts sequential throughput to 200 MB/s for backup jobs and streamlines integration with Data Protector. Benefit: 30% shorter backup windows (RPO), enhanced business continuity via Helium 512e error recovery, and optimized rack density for cost-conscious SMB environments.
