The HD MiniSAS connections are near the bracket of the controller, and the connection header for the AFM-7000 is near the right edge of the PCB. Three DRAM chips to the right of the heat sink are joined by two more chips on the bottom of the controller, for a total of 1.25GB of DRAM. The DRAM utilizes ECC, resulting in useable capacity totaling 1GB of DRAM.

The PM8063 SRCv 16x12G is a x8 PCIe 3.0 to 16-port 12Gb/s SAS RoC controller that can provide up to 8Gb/s of throughput at the PCIe slot. Due to the overhead of encoding and handshaking operations, the user-addressable speed is roughly 6.6 GB/s.
