Front and center on any RAID adapter is the RAID-on-Chip (RoC). For the Series 8, Adaptec rolled out the PM8063. This chip allows the ASR-8885 to connect to the host via x8 PCIe GEN3, with 8GB/s of bandwidth. It also allows inline XOR to reduce DDR3 access. On the adapter side, the PM8063 had 16 ports at 12Gbps.
Even though the ASR-8885 lists 1GB of DDR3 RAM, there are actually five Micron DRAM packages, each with 256MB each, for a total of 1.25GB. Three are located near the controller and heat sink, with 2 more on the back.
Near the back of this MD2 PCIe card, you can see the connector used for the AFM-700 flash-based cache protection module.
Finally, you can see the SFF-8643 internal connectors and SFF-8644 external connectors. With both external and internal ports, the ASR-8885 has a lot of flexibility.
