MICROCHIP ADAPTEC 2100-4I4E SINGLE

Product Overview

The MICROCHIP ADAPTEC 2100-4I4E SINGLE is a high‑performance Host Bus Adapter (HBA) designed for enterprise storage environments. It delivers robust connectivity between servers and SATA/SAS storage arrays, supporting both SATA3 and SAS3 drives through a single Mini‑SAS HD interface.

Key Technical Specifications

• Form Factor: Low‑profile expansion card suitable for tight rack spaces.
• Host Interface: PCIe, providing high bandwidth and low latency communication with the host system.
• Internal Mini‑SAS HD Ports: One port that aggregates up to four SATA/SAS connections.
• Native Command Queuing (NCQ): Supported, enabling efficient command scheduling for improved throughput and reduced latency.
• Reliability: Mean Time Between Failures (MTBF) of 1,400,000 hours, ensuring long‑term operational stability.
• Certifications: CE, FCC, UL, C‑tick, VCCI, KCC, CNS – compliant with global safety and electromagnetic compatibility standards.

Connectivity and Performance

The adapter’s single Mini‑SAS HD output allows it to interface seamlessly with SATA3 (6 Gb/s) or SAS3 (12 Gb/s) drives. By supporting up to four logical connections per port, the 2100-4I4E SINGLE can scale storage capacity without requiring additional hardware.

With PCIe lanes dedicated for data transfer, the HBA achieves low latency and high throughput, essential for database servers, virtualization platforms, and high‑performance computing workloads. The inclusion of NCQ further optimizes drive access patterns, reducing seek times and enhancing overall I/O efficiency.

Installation and Compatibility

The low‑profile design fits into standard 1U or 2U server chassis, making it ideal for dense rack deployments. It is compatible with a wide range of operating systems that support the SAS/SATA HBA driver stack, including recent releases of Linux, Windows Server, and various UNIX variants.

Because the adapter uses a standard PCIe interface, it can be installed in any server or blade system equipped with an available PCIe slot. The single Mini‑SAS HD port is backward compatible with older Mini‑SAS connectors, ensuring flexibility when integrating legacy storage arrays.

Use Cases

• Enterprise Storage: Connects to high‑density SAS backplanes for SAN or NAS solutions.
• Virtualization Platforms: Provides reliable block‑level access to shared storage pools used by hypervisors.
• Database Servers: Delivers low‑latency I/O required for OLTP and analytical workloads.
• Backup & Disaster Recovery: Supports large capacity arrays, enabling efficient data replication and archival.

Design Highlights

• Compact Footprint: Low‑profile card reduces rack space consumption while maintaining full functionality.
• Robust Build Quality: Constructed with high‑grade materials to withstand continuous operation in data center environments.
• Global Compliance: Meets stringent safety and electromagnetic standards, simplifying deployment across international sites.

Conclusion

The MICROCHIP ADAPTEC 2100-4I4E SINGLE combines high‑throughput connectivity, reliable performance, and a compact form factor to meet the demanding needs of modern data centers. Its support for both SATA3 and SAS3 drives, along with native command queuing and extensive certifications, makes it a dependable choice for any enterprise seeking scalable, low‑latency storage access.
