So in a nutshell, what is Vplex?
Here is how I see what VPlex does. It sits between your arrays, and hosts, and virtualizes the presentation of storage. Instead of presenting storage to the host directly, you present it to VPlex. Then you go into VPlex, configure that storage and then present it to the host. Since, VPlex is controlling the storage, it can replicate the data to another VPlex. This allows hosts on another site to access storage as if it was local to them.
Is my understanding correct? But I don't understand how it replicate the data so fast in VPlex Metro environment? There is going to be some lag between the two sites.

It seems to me that Vplex is a lot like SVC from IBM and also resembles EMC's Invista.
What I haven't seen yet, is exactly what services you can get from Vplex. Does it offer Snapshot, migrating of LUN's between different vendor arrays, mirroring of LUN between different vendor arrays? Does it offer thin provisioning? What does it have that SVC and Invista don't have?

I don’t think Vplex actually interacts with the array, it just uses the storage and presents it to the host. I think the array just sees Vplex as another host.
This makes me wonder, wouldn’t Brocade or another SAN switch manufacturer also be in the position to offer such a product? They already have a product (SAN Switch) which sits between the host and the array(s), so why not add more functionality to it.

Hi,
I just had a look at the "VPLEX Simple Support Matrix!
Wow, what a document! This is the kind of Support Matrix I like.
This can be handled, this is the way all ESM should look like.
E-Lab Navigator and current ESM is a monster.

Hello Everyone!!!
My understanding of VPLEX is that it makes the storage arrays on different sites look like one unified storage and when there is a write on the host it is sent to storage on both sites..I am starting a new project with NS480 and VPLEX..Also its integration with VMware is very interesting and I hope to learn more about this during this project...:-)
