5800 System Summary
The 5800 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, aordable, and
scalable, and to integrate data storage with intelligent data retrieval. It is designed to store huge
amounts of data for decades at a time. At that scale, issues of how and where the data is stored —
and how that changes over time — can be quite cumbersome. The 5800 system usage model is
designed to manage those issues for you, so that your application can deal with just the data.
A custom Application Programming Interface (the 5800 Client API) is provided so that your
applications can take advantage of all the features in the 5800 system usage model. The API
provides the following capabilities:
■
Store a new object into the archive (storeObject)
■
Associate a new metadata record with stored object data (storeMetadata)
■
Retrieve the data from an object that was previously stored (retrieveData)
■
Retrieve the metadata from an object that was previously stored (retrieveMetadata)
■
Delete an object (delete)
■
Query for matching objects given a query expression of specic object characteristics
(query)
The 5800 system API Release 1.1 provides two APIs:
■
The Java API is described in Chapter 2, “Sun StorageTek 5800 System Java Client API”
■
The C API is described in Chapter 3, “Sun StorageTek 5800 System C Client API”
