EMC Fibre Channel Storage System Model FC4700 Configuration Planning Guide
Planning File Systems and LUNs
Planning Applications, LUNs, and Storage Groups
This section helps you plan your storage use — the applications to
run, the LUNs that will hold them, and, for shared storage, the
Storage Groups that will belong to each server. The worksheets to
help you do this include
•Application and LUN planning worksheet — lets you outline
your storage needs.
•LUN and Storage Group planning worksheet — lets you decide
on the disks to compose the LUNs and the LUNs to compose the
Storage Groups for each server.
Unshared storage systems do not use Storage Groups. For unshared
storage, on the LUN and Storage Group worksheet, skip the Storage
Group entry.
•LUN details worksheet — lets you plan each LUN in detail.
Make as many copies of each blank worksheet as you need. You will
need this information later when you configure the storage system(s).
Sample worksheets appear later in this chapter.

Application and LUN Planning

Use the following worksheet to list the applications you will run, and
the RAID type and size of LUN to hold them. For each application
that will run, write the application name, file system (if any), RAID
type, LUN ID (ascending integers, starting with 0), disk space
required, and finally the name of the servers and operating systems
that will use the LUN.
