Making LUN Decisions
Plan your storage set up for your ESX/ESXi systems before you format LUNs
with VMFS datastores.
When you make your LUN decision, remember the following points:
•
Each LUN should have the correct RAID level and storage characteristic
for applications in virtual machines that use it.
•
One LUN must contain only one VMFS datastore.
•
If multiple virtual machines access the same VMFS, use disk shares to
prioritize virtual machines.
•
You might want fewer, larger LUNs for the following reasons:
•
More flexibility to create virtual machines without asking the storage
administrator for more space.
•
More flexibility for resizing virtual disks, doing snapshots, and so on.
•
Fewer VMFS datastores to manage.
