Dell PERC H840 12Gb/s SAS PCIe RAID Controller with Battery (Based on Avago 9400-8i). P/N: GD93V 0GD93V

This is a genuine Dell PERC H840 12Gb/s SAS PCIe RAID Controller with Battery (Dell P/N: GD93V, 0GD93V; Based on Avago/Broadcom MegaRAID 9400-8i; Other P/N: 01041M400-000-G). The H840 is an enterprise-grade hardware RAID controller designed to deliver high-performance and robust data protection for Dell PowerEdge servers, particularly for external storage enclosures. With eight internal 12Gb/s SAS3 ports (connecting to external storage enclosures via compatible backplanes), it offers superior throughput for demanding applications. Equipped with a PCIe Gen3 x8 interface and a battery backup unit (BBU), it ensures data integrity during power failures, while supporting a wide range of RAID levels for optimal flexibility and redundancy. It's an ideal solution for mission-critical applications, large-scale storage arrays, and environments requiring maximum I/O performance and data availability.

Key Features

• Genuine Dell PERC Controller: Ensures full compatibility, validated performance, and seamless integration with Dell PowerEdge servers.

• 12Gb/s SAS3 Interface: Supports the latest 12Gb/s SAS standard for high-speed data transfer to storage devices, doubling the throughput of previous 6Gb/s generations.
