Product Description
The Dell D687J is a high-performance SAS RAID controller designed to deliver robust storage solutions for Dell PowerEdge servers. Featuring a 6Gb/s SAS interface and a PCIe x8 host connection, this controller provides the bandwidth necessary for demanding enterprise workloads. It supports a wide array of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60, offering flexibility in configuring storage arrays for optimal performance, redundancy, or a balance of both. This controller is capable of managing both SAS and SATA drives, allowing organizations to leverage the cost-effectiveness of SATA drives while maintaining the performance and reliability of SAS for critical applications. Hardware RAID acceleration ensures that RAID calculations are handled efficiently by the controller's dedicated processor, freeing up the server's CPU resources and improving overall system responsiveness. Many versions of this controller also support optional battery-backed write cache (BBWC) or flash-backed write cache (FBWC) to protect data in the event of a power failure. As a key component for enterprise storage, the Dell D687J enables the creation of highly available and high-performance storage subsystems. It is crucial for applications such as databases, virtualization, video editing, and large-scale data analytics where data integrity and rapid access are paramount. Its integration into Dell PowerEdge servers ensures compatibility and optimized performance within the Dell ecosystem.
