Storage Explained

GRAID

Local Storage/Direct Attached Storage

Typically this is defined as storage with no ability to provide any real-time sharing capability. Most common is the FireWire,  USB 3.0 or ThunderBolt drive, used for moving media from a shoot for example, but local storage is also used when bandwidth demands become too costly an option for shared online storage.

Shared storage can be broken down into three areas:

DVS-SAN

Online

This provides the ability to manage high bandwidth video requests from multiple users in real-time. This high demand requires specialised drives and connectivity and fibre is commonly used here. This high-performance storage is the most expensive variety so if media is not being actively used then it is best to demote this media to:

isilon-fanout

Nearline

Once the media is here it can still be managed but a key consideration is the speed of transfers in and out of online storage. As the demands of nearline are significantly less, costs are reduced with commodity drives and connectivity via Ethernet.

RLS8500

Archive

Once projects are finished, they need to be archived. Here, although the media may still be managed and reloaded, access is obviously more time consuming. The archive has responsibility for secure long term storage and the provision of disaster recovery. Typically this operation is off site using data tape based technologies.

Throughout all of these storage types, backup must be considered and the commonly used term RAID can be confusing. Typically RAID, while allowing for fast recovery from basic failures, does not provide total backup for your media.

The archive is also important to manage backups of media throughout the production process.
