The
Phoenix Information Repository
An efficient, structured, searchable environment for managing and storing digital
assets, the Phoenix Information Repository is the heart of Phoenix. By ingesting eligible
data assets and associated metadata into secondary storage,
and managing them, the Information Repository maximizes primary storage and
reduces management burdens. Phoenix is the answer to your digital asset
management requirements.
Within the Information Repository, ingested digital assets and metadata is
stored on media that is housed within vaults. Digital assets are managed
utilizing Data Service Polices that automatically store, process, and
preserve ingested data in according to its
service level requirements and recovery time objectives.
Vaults
Vaults are central to the Phoenix Information Repository. They are independent, self-contained storage resources deployed
throughout the Information Repository, which utilize media of various
types. A vault comprises a host processor, resources for the various metadata
catalogues, and a mass storage device used for data storage.
Vaults are automatically recognized as viable
storage resources as soon as they come on line, so they can be added,
moved, or removed from a configuration without serious management
intervention.
Media
Phoenix vaults can utilize a wide variety of media technologies to ensure
that data retrieval time objectives (RTO) and storage longevity requirements are met. Supported media types
include all types of hard disk, most digital tape technologies, as well as magneto
optical (MO) and DVD glass media.
Media may be utilized on an individual basis, or several media units may be grouped together to form pools.
Media pools can span vaults and can even comprise multiple media technologies, which provides resource
fail-over and other capabilities.
Metadata Processing
As data is ingested into the Information Repository, files are assigned
an identification (ID) and a digital fingerprint.
Next, context metadata is extracted from the data and indexed into a
catalog, which reside both in the vault and on the media storing the
data.
Context metadata, such as file name, ownership information,
permissions, etc., and content information in the form of key words and
phrases are used for filtering parameters within Data Service Policies and during search and discovery processes.
Component-assigned Processing
The level of metadata extracted during ingest is managed via a
tunable parameter. Processes such as metadata extraction and
de-duplication can be part of Data Service Policies.
This provides a great deal of flexibility and efficiency to a Phoenix
solution by enabling CPU intensive processing to be conducted only where
it is needed within the Information Repository. For example, in cases where network impact needs to be kept to an
absolute minimum, Phoenix can be set to extract only a minimal amount of
metadata during ingest. Once in the Information Repository, data can be consolidated to media where
additional metadata, such as content,
is then extracted and stored
for use
in policy filtering at the vault
or
media level.
Data Service Policies
Data Service Policies manage data throughout the Information Repository. They may be very
simple or highly complex, depending on the requirements of the data being managed.
A very simple Data Service Policy might be used to move data initially stored on a disk-based
vault to one based on tape, as time or access level parameters are met.
More complex Data Service Policies can be deployed to migrate information through a
hierarchy of storage that continually meets data's access performance, RTO, storage
longevity, and other service level requirements. Filters can be utilized to work within classification
and consolidation policies that move information to pre-defined storage pools.
Policies may also be designed to perform end of life operations on data that is
no longer relevant.
Benefits provided by the Phoenix Information Repository:
- Digital Asset management
- Protective storage of network data
- Digital fingerprinting
- Indexing of stored data for easy searching and retrieval
- Virtual tiered structuring of data for hierarchical data migration and
replication
- Automatic elimination of eligible data
