Storage Configuration Planning
This is the most important part to use the SAN storage system effectively. Depending on
your application, estimated volume capacity, and disk failure risk, you should have a well-
thought out storage plan. Complete all storage configuration planning jobs on part 6, pool
configuration, part 7, volume configuration, part 8, LUN mapping configuration, and part 9,
SSD cache configuration.
Planning the Disks
To plan the disk drives, determine:
The cost/performance ratio of the disk drive type.
Estimate the total required capacity of the system.
Whether the disk drives are SSDs.
Quantity of spare disks. Recommend for hot spare to active drive ratios, 1 in 30 for SAS
drives and 1 in 15 for NL-SAS.
Planning the Pools
Necessary activities are in the following, please fill in part 6, pool configuration, in Table 2-1.
The pool name, the maximum length of name is 16 characters.
According to the pool and disk drive characteristics, such as total capacity, budget,
performance, and reliability, determine a pool type (thick, thin provisioning, or auto
tiering) and a RAID level of storage systems to use. For example, create a pool which is
grouped by RAID 10 for performance and RAID 5 in another storage pool to achieve
desired results.
Plan to extend the capacity of the storage pool in the future.
Planning the Volumes
A volume is a member of the pool. Determine the following items and fill in part 7, volume
configuration, in Table 2-1.
The volume name, the maximum length of name is 32 characters.
The volume capacity.
Plan the volume capacity for local clone or remote replication. Set it as RAID volume for
normal RAID volume usage, or set it as backup volume for the backup target of local
clone or remote replication.
