Greets everyone!

Right now we're performing a fresh install of vplex + VNX solution. Vplex will service a vmware environment and a small bunch of Oracle hosts.

I've tried to find any notes about storage provisioning best practices for vplex and found almost nothing.

I observe 2 approaches  how I can provision storage for a vplex:

1. Create a multiple LUN's (or meta LUN's) on VNX array (each LUN for certain purpose like VMFS datastore, RDM device, or file system). Then present it to vplex, create an extent then device and then a volume which is presented to the host.

OR

2. Create a large LUN's (like single LUN for entire storage pool) on VNX array and present these large LUN's to vplex. Then slice these storage volumes to extents of any size I need and create devices and volumes on top of it.

Approach #1 will force me t manage 2 layers of storage provisioning. This is complex (pretty much complex ). But it provides me more control over storage traffic and gives me ability to leverage VNX Storage QoS for certain LUN's. While Approach #2 make storage provisioning quite simple. But I'll be forced to use SIOC in vmware to handle performance issues (if they occur).

So I'd like to ask you which of these models of storage provisioning you're using now? And why you're using it

Thanks.
