Connectivity and compatibility

This controller connects to external storage enclosures using two Mini-SAS HD ports, each providing four lanes of 12G SAS bandwidth. It supports a broad range of SAS and SATA drives, making it suitable for mixed storage environments. The card fits into a PCIe 3.0 x8 slot on HPE ProLiant Gen10 servers, ensuring high-speed data transfer and compatibility with existing server infrastructure. It is validated for use with HPE D3610, D3710, and D6020 enclosures, which helps streamline storage expansion and management.

Installation and setup

Installing the controller is straightforward: insert the card into an available PCIe 3.0 x8 slot and connect Mini-SAS HD cables to your external drive enclosures. Configuration and management are handled through the HPE Smart Storage interface, which many administrators will find familiar and efficient. Note that the Smart Storage Battery, which is necessary for full cache protection, must be purchased separately to ensure data safety during power interruptions.

Ideal uses and environments

This controller is well suited to environments that require scalable and reliable external storage, such as virtualization clusters, backup targets, and tiered storage pools for data analytics. Its ability to run RAID and HBA modes simultaneously allows IT teams to optimize performance and flexibility within a single card. Organizations needing encrypted storage for compliance can add the optional license to secure data at rest. Overall, it fits well in enterprise data centers and professional IT setups that demand high throughput and robust data protection.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
