Storage Array Lenovo ThinkSystem DE4000 HIC 12Gb SAS (MPN 4C57A14367)

The Lenovo ThinkSystem DE4000 HIC 12Gb SAS is a host interface card designed for use with DE4000 series storage arrays. It provides 12Gb/s SAS connectivity to link the storage controller to hosts or disk enclosures, supporting high-throughput data transfer in SAN environments. The module is intended to extend storage capacity, enable direct-attached expansion or fabric connectivity, and facilitate faster backup and recovery operations when deployed in enterprise storage architectures.

Advantages

This 12Gb SAS HIC delivers increased bandwidth compared with previous-generation interfaces, reducing bottlenecks for I/O-intensive workloads. The module is engineered to integrate with DE4000 series arrays, maintaining compatibility with array management and firmware. Its design supports resilient connections for SAN topologies and can assist in consolidating storage traffic while preserving predictable performance for mixed workloads.

Suitable for

• Enterprise SAN interconnects between DE4000 arrays and servers or expansion enclosures
• Storage capacity expansion and disk enclosure linking
• High-performance backup and recovery operations that require sustained throughput
• Environments with mixed I/O workloads requiring reliable SAS connectivity

Key specifications

• Interface type: 12Gb SAS host connectivity
• Form factor: pluggable HIC module compatible with DE4000 series
• Purpose: host or expansion link for storage arrays and disk enclosures
• Typical use: SAN deployment, expansion interconnects, backup/recovery acceleration

How to use

Install the HIC into the designated HIC slot or bay on a compatible DE4000 series storage array following the array service manual and standard safety procedures. Connect appropriate 12Gb SAS cables between the HIC ports and target servers, host bus adapters, or expansion enclosures. Verify firmware compatibility and update the array firmware if required, then use the array management interface to configure host paths, multipathing, and zoning according to your SAN topology and operational policies.

Recommendations

Use certified 12Gb SAS cabling and ensure end devices (HBAs, enclosures) support the same link speed to achieve optimal throughput. Maintain firmware parity across the storage array and HIC module, and validate multipath configuration to ensure redundancy and load balancing. For critical workloads, test performance under expected load and monitor link status and error counters regularly.
