Technologies are generally described to establish a hardware interconnect based communication between SSD controllers. According to some examples, a first solid state drive (SSD) controller and a second SSD controller are detected. The hardware interconnect is detected between the first SSD controller and the second SSD controller. Next, a communication connection between the first SSD controller and the second SSD controller is established through the hardware interconnect. The first SSD controller may be allowed to manage a flash controller of the second SSD controller for tasks that include a deduplication task and a low level redundant array of independent disks (RAID) task.
