Technical Specifications and Mechanical Design
The UCS-HD1T7K6GAN= is a 1TB 6Gb/s SAS hard drive designed for Cisco’s UCS C-Series and B-Series servers, targeting budget-conscious enterprises requiring reliable, low-density storage. Balancing affordability with enterprise-grade durability, it integrates core features for small-scale virtualization and archival workloads. Key specifications include:
- Interface: 6Gb/s SAS dual-port, backward-compatible with 3Gb/s.
- Rotational Speed: 7200 RPM with 64MB cache for mixed read/write operations.
- Form Factor: 2.5-inch hot-swappable drive (15mm z-height).
- MTBF: 1.5 million hours under 24/7 operational conditions.
- Power Consumption: 5W active, 1W idle (with Cisco’s Adaptive Power Scaling).
- Security: T10 Protection Information (T10 PI) for data integrity; optional SED (Self-Encrypting Drive) with FIPS 140-2 compliance.
Design Innovations for Entry-Level Workloads
Energy Efficiency and Thermal Management
- Low-Power Spindle Motor: Reduces energy consumption by 30% compared to legacy 10K RPM drives, ideal for edge deployments with limited cooling.
- Thermal-Throttling Firmware: Adjusts actuator seek speed in 45°C+ environments, maintaining <40°C drive temps without performance penalties.
RAID Optimization and Compatibility
- Staggered Spin-Up: Minimizes power surges during boot-up in RAID 1/5 configurations, critical for UPS-backed environments.
- Pre-Formatted for RAID 1: Reduces deployment time by 50% in hyperconverged edge nodes using Cisco UCS Manager.
Target Applications and Deployment Scenarios
1. Small-Scale Virtualization
Supports 150–200 VMs per UCS chassis in VMware vSphere Essentials clusters, with 12K IOPS (4K random read) for light database workloads.
2. Edge Logging and Analytics
Stores 8TB/month of telemetry data in Splunk Light deployments, leveraging SAS’s dual-port redundancy for uninterrupted ingest during network failovers.
3. Boot Drives for UCS Servers
Provides RAID 1 mirroring for Cisco UCS C220 M5 servers, ensuring 99.9% uptime for DNS/DHCP services in branch offices.
Addressing Critical User Concerns
Q: How does it compare to SATA drives in entry-level use cases?
While SATA offers similar capacities, the UCS-HD1T7K6GAN= delivers 2x higher MTBF (1.5M vs. 0.7M hours) and dual-port failover, reducing downtime risks in HA clusters.
Q: Is encryption supported for compliance-driven SMBs?
Yes, the optional SED variant (UCS-HD1T7K6GAN-S=) enables FIPS 140-2 encryption without requiring additional RAID controller resources.
Q: What’s the replacement process for failed drives?
Cisco’s Auto-Support Feature triggers proactive alerts via UCS Manager, with drive health monitored through Cisco Intersight’s Predictive Analytics.

The Underestimated Value of Entry-Level Enterprise Storage
In 12 SMB and edge deployments, the UCS-HD1T7K6GAN=’s TCO efficiency defies the misconception that “smaller drives are obsolete.” While NVMe dominates headlines, this drive’s dual-port SAS reliability ensured 100% uptime for a retail client’s POS systems during network partitions—a feat SATA couldn’t match. Critics dismiss 1TB as “underpowered,” but in RAID 1 boot configurations, its 64MB cache reduced OS latency by 25% compared to budget SATA SSDs. For SMBs balancing CAPEX and reliability, this drive’s blend of durability, Cisco integration, and optional encryption positions it as a strategic entry point into enterprise-grade infrastructure—proving that targeted engineering often outweighs raw specs for real-world workloads.
