초록

Digital objects are stored and accessed within a fixed content storage cluster by using a page mapping table and a pages index. A stream is read from the cluster by using a portion of its unique identifier as a key into the page mapping table. The page mapping table indicates a node holding a pages index indicating where the stream is stored. A stream is written by storing the stream on any suitable node and then updating a pages index stored within the cluster responsible for knowing the location of digital objects having unique identifiers that fall wi...

1. A method of recovering from a node failure within a storage cluster, said method comprising: detecting within said storage cluster that a first computer node out of a plurality of computer nodes is unavailable, said storage cluster including stored digital objects in persistent storage, each of said digital objects being identified by a unique identifier (UID), and wherein said unique identifiers having ranges of possible values, wherein a first UID range being mapped to said first computer node;replacing said mapping of said first UID range to said f...
