Planning the LUNs
LUN is a unique identifier which volume maps it to differentiate among separate devices. At
the same time, there are some access controls by allowed hosts, target, LUN (logic unit
number), and read/write permission. Please fill in part 8, LUN mapping configuration, in
Table 2-1.
Prepare an allowed host list for access control. They are (iSCSI Qualified Name) or Fibre
Channel WWNN (World Wide Node Name). Set it as wildcard (*) for access by all hosts.
Select an iSCSI target for iSCSI network portal. Or a FC target.
Support LUN from 0 to 255.
Usually, set the volume as read-write permission. For read only purpose, set it as read-
only.
Planning the SSD Cache
Optionally, preparing for some SSDs will enhance the system performance. Please fill in part
9, SSD cache configuration, in Table 2-1.
For SSD cache planning, the capacity of read cache is the sum of SSDs. But the capacity
of read-write cache is half of all SSDs because it needs RAID protection for write buffer.
2.1.7.
Backup Configuration Planning
Backup plan is also an important job for disaster recovery. Complete the backup
configuration planning jobs on part 10, snapshot configuration, part 11, local clone
configuration, and part 12, remote replication configuration.
Planning the Snapshots
To plan the snapshots, you have to reserve some snapshot spaces from the pool. Normally,
we suggest reserving
20%
of the volume capacity as a minimum.
Select a volume and reserve its snapshot space.
Plan the schedule of snapshots, determine the cycle of taken snapshots. It can be hourly,
daily, or weekly.
Planning the Local Clones
To plan the local clones, you have to select a source volume and prepare a target volume
which the source clones to.
