- This abstract for appeared for US patent application number 17725087 Titled 'CAPACITY-BASED REDIRECTION EFFICIENCY AND RESILIENCY'
Simplified Explanation
The abstract describes a system where a database manager keeps track of storage units and storage appliances. Some of this tracking information is stored in a server cache and client caches. When a client wants to access a storage unit but encounters a problem using its cache, it queries the namespace redirection server for updated information about the storage unit's location. The client also helps manage the server cache.
Original Abstract Submitted
A database manager maintains a database including information tracking a set of storage units and a set of storage appliances on which the storage units currently reside. At least a portion of the tracking information is cached in a server cache at a namespace redirection server. Some of the tracking information is cached in a set of client caches at a set of clients. A request to access a storage unit is received at a client. A lookup is made into a client cache at the client to find a storage appliance having the storage unit. A determination is made that there is a problem accessing the storage unit using the client cache. So, the namespace redirection server is queried for updated tracking information concerning a location of the storage unit. The client assists the namespace redirection server with management of the server cache.
