Details of Cisco UCS-C3K-HD4TB 4TB HDD

The Cisco UCS-C3K-HD4TB 4TB 7.2K RPM SAS 12Gbps Hard Drive With Tray is an enterprise-class storage component designed for high-reliability computing environments where predictable performance, continuous uptime, and scalable capacity are essential. Built for Cisco Unified Computing System (UCS) infrastructures, this 3.5-inch large form factor (LFF) hard drive integrates seamlessly into rack-mounted servers and storage nodes that demand stable data throughput and long-term operational endurance. With a 4TB storage capacity, 7200 RPM rotational speed, and 12Gbps SAS interface, this drive is engineered to support enterprise workloads such as virtualization, cloud storage, database management, backup systems, and large-scale file repositories.

Enterprise Storage Architecture

Within Cisco UCS architectures, storage components such as the UCS-C3K-HD4TB play a foundational role in enabling scalable and unified data center operations. Cisco UCS environments are designed to integrate compute, networking, and storage resources under a single management framework, and this hard drive contributes directly to the storage layer of that ecosystem. Its compatibility with UCS servers ensures that administrators can deploy and manage storage efficiently using centralized tools, reducing operational complexity while improving system reliability.

System Integration Benefits

The integration of this drive into Cisco UCS systems allows organizations to benefit from streamlined provisioning and automated storage configuration. This reduces manual intervention and ensures that storage resources are consistently aligned with workload requirements. The UCS architecture enables dynamic scaling of storage capacity, and the 4TB SAS drive provides a balanced option for environments requiring moderate capacity expansion without sacrificing enterprise reliability.

12Gbps SAS Interface Performance

The 12Gbps Serial Attached SCSI (SAS) interface is a defining feature of the Cisco UCS-C3K-HD4TB. It provides high-speed data transfer capabilities that ensure efficient communication between the storage device and server backplane. SAS technology supports full-duplex communication, enabling simultaneous read and write operations, which is critical in high-demand enterprise environments. Additionally, the dual-port architecture enhances redundancy by allowing multiple data paths to the drive, increasing fault tolerance and system availability.

Throughput Optimization

Enterprise SAS drives utilize advanced command queuing mechanisms that optimize I/O performance under heavy workloads. The Cisco UCS-C3K-HD4TB can process multiple simultaneous requests by intelligently reordering commands to minimize latency and maximize throughput. This capability is particularly beneficial in environments such as virtualization clusters and transactional databases where multiple users or applications generate continuous data requests.

Data Integrity 

Data integrity is a critical requirement in enterprise storage systems. The SAS architecture used in this drive includes robust error detection and correction capabilities that help ensure data accuracy during transfer and storage. These mechanisms reduce the risk of silent data corruption and enhance reliability in mission-critical applications where data consistency is essential.

Balanced Capacity for Enterprise Workloads

The 4TB capacity of the Cisco UCS-C3K-HD4TB provides a balanced storage solution for organizations that require moderate to high-capacity storage without transitioning to ultra-large drives. This capacity is ideal for structured storage environments where data needs to be distributed across multiple drives for performance and redundancy purposes. It enables efficient storage allocation in both small-scale and large-scale enterprise deployments.

Rotational Speed and Workload Balance

The 7200 RPM rotational speed of the Cisco UCS-C3K-HD4TB represents a balanced approach between performance and efficiency. While higher RPM drives offer lower latency, they also consume more power and generate more heat. The 7200 RPM configuration is optimized for workloads where sustained throughput and capacity are prioritized over ultra-low latency, making it suitable for archival storage, backups, and general enterprise workloads.

Hot-Swap Capability for Continuous Operation

Hot-swap functionality enables the drive to be replaced or installed without shutting down the system, which is critical for maintaining uptime in enterprise environments. The Cisco UCS-C3K-HD4TB supports hot-swapping in compatible systems, allowing IT administrators to perform maintenance or upgrades without disrupting ongoing operations.

Vibration Resistance in Dense Storage Arrays

In multi-drive server configurations, vibration from adjacent drives can impact performance. This drive is designed with vibration resistance mechanisms that maintain stability even in dense storage arrays. This ensures consistent performance and extends the operational lifespan of the drive.

RAID Compatibility and Redundancy Architectures

The Cisco UCS-C3K-HD4TB is commonly deployed in RAID configurations that enhance data redundancy and performance. Depending on system requirements, it can be used in RAID 0, RAID 1, RAID 5, RAID 6, or RAID 10 setups. These configurations provide flexibility in balancing performance, fault tolerance, and storage efficiency across enterprise systems.

Data Center Deployment and Scalability

This drive is designed for seamless integration into Cisco UCS rack server environments, allowing organizations to scale storage capacity as needed. Its compatibility with UCS systems enables incremental expansion without requiring major infrastructure changes.

Firmware Integration with Cisco UCS Platforms

Cisco UCS systems are optimized to work seamlessly with compatible storage devices. The Cisco UCS-C3K-HD4TB benefits from firmware-level integration that ensures efficient operation and simplified management within UCS environments.

Storage Controller Performance Coordination

Enterprise storage controllers play a critical role in optimizing drive performance. These controllers manage SAS bandwidth and command scheduling to ensure consistent throughput and system efficiency when using the Cisco UCS-C3K-HD4TB.
