Dedup storage pools cannot exceed 32TB in size.

When creating storage pools, it is important that you do not use the two physical devices that
are to act as the Configuration Repositories.

Creating and Managing LUNs on a Shelf
For information and procedures on how to create and manage a LUN on a shelf in a local network,
see the topic on creating LUNs in the latest version Symphony Help, which provides:
•
A list of recommended guidelines that are useful for planning and creating southbound data
LUNs.
•
A procedure for creating a LUN and adding it to a storage pool.
Overview: LUN Types
When creating and exporting LUNs from a supported shelf to a 7700 FSP Controller, there are three
possible types of LUNs:
•
Dedup
: A deduplication LUN could be grouped together into a separate storage pool to create
a dedup storage pool at the 7700 FSP Controller level. Dedup LUNs are not supported at the
7700 FSP Controller level, and must be provisioned at the shelf level.
•
Thick
: A thick LUN could be grouped together into a separate storage pool to create a thick
storage pool at the 7700 FSP Controller level.
•
Thin
: A thin LUN could be grouped together into a separate storage pool to create a thin
storage pool at the 7700 FSP Controller level.
•
Primary LUN purposes
:
— Configuration Repository (CR)
— Data
Note:
LUNs must be 512-byte blocks. LUNs that are 4096 block size are not supported.
For the CR, which you enable using Symphony, create two non-ALUA LUNs with a minimum size
of 11GB. Use Symphony to share/assign the new 11GB LUNs to both 7700 FSP Controllers with
read/write (shared) access rights. For details, see the topic on assigning and unassigning SAN
clients in the latest version Symphony Help.
Note:
Before you can create LUNs, you must first create storage pools. When you create a LUN,
you need to select the storage pool in which it will reside.
In a modular 7700 FSP storage cluster (non-stretch cluster), each 7700 FSP Controller requires
only one CR. If there are multiple storage shelves in the configuration, you need to select one of
them to act as the CR.
