发明名称 Method for setting parameters and determining latency in a chained device system
摘要 A storage system and method for setting parameters and determining latency in a chained device system. Storage nodes store information and the storage nodes are organized in a daisy chained network. At least one of one of the storage nodes includes an upstream communication buffer. Flow of information to the storage nodes is based upon constraints of the communication buffer within the storage nodes. In one embodiment, communication between the master controller and the plurality storage nodes has a determined maximum latency.

主权项 1. A storage system comprising: a plurality of storage nodes for storing information wherein said plurality of storage nodes are organized in a chained network and at least one of said plurality of storage nodes includes an upstream communication buffer; and a master controller for controlling flow to said plurality of storage nodes based upon constraints of said upstream communication buffer within said plurality of storage nodes, wherein a communication of a given burst length between said master controller and any of said plurality of storage nodes has a same estimated maximum possible latency, and wherein a maximum possible latency for communication to any storage node is estimated based on: a minimum latency of a most distant storage node,a quantity of storage nodes in the plurality of storage nodes, anda burst length of the communication and a clock period, wherein said information is independent of an actual latency in a recent read operation, and wherein a minimum possible latency for any storage node other than the most distant storage node is less than the maximum possible latency, wherein said upstream communication buffer is configured to store a response from a first storage node of the plurality of storage nodes in response to a collision with a response from any downstream storage node of the plurality of storage nodes.
