5800 SystemSummary

The5800 system is an object-based storage archive appliance for xed-content data and
metadata.The 5800 system is designed from the ground up to be reliable, aordable, and
scalable,and to integrate data storage with intelligent data retrieval. It is designed to store huge
amountsof data for decades at a time. At that scale, issues of how and where the data is stored —
andhow that changes over time — can be quite cumbersome. The 5800 system usage model is
designedto manage those issues for you, so that your application can deal with just the data.
Acustom Application Programming Interface (the 5800 Client API) is provided so that your
applicationscan take advantage of all the features in the 5800 system usage model. The API
providesthe following capabilities:
■Storea new object into the archive (storeObject)
■Associatea new metadata record with stored object data (storeMetadata)
■Retrievethe data from an object that was previously stored (retrieveData)
■Retrievethe metadata from an object that was previously stored (retrieveMetadata)
■Deletean object (delete)
■Queryfor matching objects given a query expression of specic object characteristics
(query)
The5800 system API Release 1.1 provides two APIs:
■TheJava API is described in Chapter 2, “Sun StorageTek 5800 System Java Client API”
■TheC API is described in Chapter 3, “Sun StorageTek 5800 System C Client API”
