Storage Configurations
30
n
In a basic configuration containing one or two engines, each of the engines contains two ISS
modules. The IXS module is used with an ISS module in an engine only when the configuration
goes beyond two engines.
Storage Configurations
A maximum of twelve Avid ISIS Engines can be stacked and populated with either 250 GB,
500 GB, or 1 terabytes (TB) SATA drives. A fully populated Avid ISIS system with 1 TB drives
provides up to 384 terabytes (TB) of storage, or 192 TB of mirrored storage.
You can have mixed ISB drive sizes in an engine (250 GB, 500 GB, and 1 TB drives). You can
even mix the different size ISBs in a Storage Group. Although, the larger ISBs in the mixed
Storage Group only use the amount of storage that is available in the smaller ISBs.
Storage Group Size
Storage elements are combined to create Storage Groups in the ISIS file system. These Storage
Groups can be configured to either operate using 512 KB (default) or 256 KB chunk sizes.
Earlier Avid ISIS releases used 256 KB chunk sizes. For more information about setting the
chunk size, see the
Avid ISIS Administration Guide.
n
Avid ISIS 7000 switch hardware shipped with v1.x (ISS1000 and IXS1000) does not support 512
KB chunk sizes. If you have Avid ISIS 7000 v2.x software running on v1.x switches, you must
select the 256KB chunk size when adding storage elements to the file system to create Storage
Groups.
You cannot change the chunk size of a Storage Group once the Storage Group has been created.
To change the chunk size of an existing Storage Group, you must delete the Storage Group and
create a new Storage Group with the desired chunk size. The chunk size selection is only
available when adding the storage elements.
c
When you delete Storage Groups all data on that Storage Group is lost.
