Workspace Considerations
Before you create Workspaces:
• Consider how you want to allocate them. For example, do you want to allocate them to accommodate projects,
groups, individual clients, streaming bit rates, media types, media distributors, or a combination of these?
• Determine how much storage each Workspace requires and allocate space accordingly. This might be a function
of project size or the number of clients, or it might be a function of media duration or media resolution.
• On ISIS | 7500 systems, consider the chunk size implications. Workspaces can be moved only to Storage
Groups with the same or a larger chunk size.
In a multiple Workspace configuration, consider reserving some space rather than assigning all of it immediately.
Once space is allocated, it tends to be filled quickly and you might need space later to accommodate a new project or
client or to extend or protect an existing Workspace. In these situations, it is easier to use space held in reserve than
to take it away from an existing Workspace.
When allocating and sizing Workspaces, also consider whether access restrictions are required and whether
protection for data integrity is necessary for each Workspace.
The sections below describe Workspace considerations that apply only to ISIS | 7500 because of the different
Workspace protection modes available. On ISIS | 5500, the only data protection mode is hardware RAID; on ISIS |
2500, the only protection mode is software RAID.
Workspace Data Protection (ISIS | 7500 only)
Avid ISIS | 7500 supports two types of Workspace data protection: mirrored and redundant array of independent
disks (RAID-6), which in turn depends on the number of Storage Managers in the Storage Group:
• For Mirrored Workspaces there must be at least two Storage Managers in the Storage Group
• For RAID-6 Workspaces there must be at least eight Storage Managers in the Storage Group, and the Chunk
Size must be 512 KB. RAID-6 storage provides more storage at a lower cost per GB.
Workspace Creation (ISIS | 7500)
The following table describes what protection modes you can apply to a Workspace in a Storage Group on an ISIS |
7500 depending on what the Storage Group already contains.
