A service realized by this Pattern offers its clients data preservation and data retrieval functionality with the following characteristics:
* operates on data at the lowest abstraction level, i.e. "unstructured data" (e.g. bits and bytes),
* located at one logical location,
* access by general or dedicated storage network facilities (indicated by [[GP.Data Transport|Data Transport]]),
* the ability to perform storage related "intelligent" tasks, such as replication, migration, encryption and data reduction. This intelligence is characterized as "back-end facing" intelligence; generally speaking the facility's users don't get (direct) access to it, only the administrators and back-end systems.

As examples: realizations of Raw Storage can include:
* SAN solutions,
* (the back-end of) NAS appliances,
* hard disk solutions.

{{Generic Pattern Composition}}
{{Generic Pattern Composition Row
|function=GF.Retention Engine
|choice=Must
|reason=This function provides "intelligence" to the storage solution with respect to its handling of the stored data, with the aim of meeting the quality requirements, improving infrastructure management, and/or providing sufficient performance. It may handle migration/replication to other instances of itself, encryption, reduction, and other "standard" storage-related processing. Note that for some types of functionality an implementation/realization of Retention Engine may need to invoke another implementation/realization (e.g. for replication/migration over longer distances, there likely is a separate realization in each physical location).
}}
{{Generic Pattern Composition Row
|function=GF.Raw Retention
|choice=Must
|reason=This function handles the actual retention of data at the "unstructured data" level. It supports the actions creation, reading, updating and/or deletion of the data.
Physically this function can be realized with devices containing (re)writeable media, such as Solid State Disks, hard disks, tape, optical media et cetera.
}}
{{Generic Pattern Composition Row
|function=GF.Caching
|choice=May
|reason=An intelligent storage facility may use Caching functionality to increase its capacity to receive and/or return data on request.
}}
{{Generic Pattern Composition Row
|function=GF.Controlling
|choice=May
|reason=If implemented, this function can be used by administrators, and possibly by authorized clients, to change the way the Pattern works. Among the changes that can be made via this function are:
* Creating or changing back-up schedules;
* Restoring back-ups;
* Capacity & Performance Management;
* Provisioning;
* Rules Management, in order to guide data migration between Tiers.
Care must be taken to limit access to this function to authorized systems and users.
}}
{{Generic Pattern Composition Row
|function=GF.Encryption
|choice=May
|reason=This function ensures that all data gets written in an encrypted form; after this, any reading, updating, and possibly deleting, can only take place if a client can offer this Pattern the right encryption key. If an implementation of this Pattern is to help maintain the Confidentiality of the data contained, then this function is required.
}}
{{Generic Pattern Composition Row
|function=GF.Reduction
|choice=May
|reason=To increase the data capacity of the Pattern, the Reduction function may be used to reduce the size to the data actually stored by Raw Retention, compared to the size of the data offered to the Pattern by its clients. Usually this Reduction function works lossless, meaning that upon access, the data can be reproduced exactly as it had been offered. Reduction of unstructured data can take place by different means, mainly data compression algorithms and/or sparse volumes/thin provisioning.

{{Generic Pattern Adjacent Service Row
|service=GS.Backup Management
|choice=May
|reason=If the data stored in this Pattern requires one or more secondary copies (backups), then this service can create and manage these.
}}
{{Generic Pattern Adjacent Service Row
|service=GS.Data Transport
|choice=May
|reason=This service is needed to transport the data from the clients to the Pattern and back. Raw Storage facilities often use specialized Data Transport services, instead of the generic "network" services.
