Protecting ISIS | 7500 Workspaces

Because of the potential impact of a drive failure, Avid recommends protecting all your Workspaces whenever

possible. On the ISIS | 7500, workspace protection is optional. If you want to ensure protection of your files at all

times, always choose a Protection option when creating new Workspaces (before any files are stored on the

Workspace).

If you are not sure that all files on a given Workspace are protected, select the Workspace and enable the available

Protection option for the Workspace. This protects all new files added to the Workspace, and adds protection to any

existing files in the Workspace that are not already protected. Using RAID-6 protection on Workspaces has the

following advantages:

• Migration from mirrored to RAID-6 Workspaces can become part of your normal workflow. You can move the

data that is no longer used in the mirrored Workspaces to RAID-6 Workspaces for long term storage. This frees

up faster Storage Managers for higher performance work.

• RAID-6 Workspaces allow you to use low bit-rate data, at less cost.

The following table summarizes the advantages and disadvantages of the different protection types:

RAID-6 Workspaces have the following restrictions:

• Require a Storage Group with a 512 KB chunk size (256 KB chunk sizes are not supported).

• Require a Storage Group with at least 8 Storage Managers.

• Require ISIS v2.x generation switches (ISS2000/IXS2000) in the ISIS Engines (these switches are also required

for 512 KB chunk sizes).

• Support only resolutions that draw 16 MB/s (50 Mb/s) or less.

For example, you can run two streams of DV 50 or DNxHD 36. Bandwidths are listed by resolution and number of

streams on the Avid Knowledge Base. Search the Avid Knowledge Base for the Avid ISIS Performance Guide.

• If a RAID-6 Workspace experiences two disk failures, capturing (or writing) to the Workspace is not supported

until the error condition is corrected.

• Before you perform a full redistribution, all clients must stop using that Storage Group and unmount the

Workspaces in that Storage Group.

Type Advantages Disadvantages

Mirrored • Maximizes performance of protected

Workspaces

• Supports high-resolution workflows

• Mirrored Workspaces use twice as much space as

unprotected Workspaces

• Tolerates single Storage Manager failure

RAID-6 • Maximizes protected storage capacity

• Tolerates two Storage Manager failures

• Supports low bit-rate (<=50 Mbs) workflows
