It uses the RAID-II controller's memory (32 MB) to pipeline data transfers from the RAID disks directly to (from) the network. Thus, data never flows through the server CPU or memory. The server remains in control, telling the controller where each block goes, etc. They get very high data rates. And despite being much faster than the RAID for small writes, they were still CPU-limited, because the CPU had to handle all the little requests.} }
