Climbing The Mountain: Storage challenges with virtual infrastructure

EMC VP Chuck Hollis details his thoughts on the challenges facing the enterprise with their storage infrastructure and virtualization using VMware. I’ve excerpted a bit, but read the whole thing.

The Core Infrastructure Challenge

Simply put, the central infrastructure challenge is that server
virtualization adds another layer in the stack.  As an example, instead
of server / network / storage, it’s now virtual server / physical
server / network / storage.  …

Challenge #1 – Flat Name Space for VMotion

One of the most powerful and sexy features in VMware ESX 3.0 is the
advanced capabilities of VMotion, managed by DRS. … But this presents a new challenge to the storage infrastructure.
You’re going to want the ability for every virtual server image to be
able to see every storage object from every server. …

Challenge #2 – Storage Resource Management

The starting point for enterprise-class SRM is discovery and
visualization.  What do I have, how does it connect, and how is it all
related? … Now, insert server virtualization into this stack. … What happens?  It breaks the connection.  Maybe I can see the
virtual machines.  Or maybe I can see the VMware ESX servers.  But,
unless some heavy lifting is done, I won’t be able to see that
stem-to-stern view that makes enterprise SRM useful.  And you can’t
manage what you can’t see. …

Challenge #3 – Backup and Recovery

Backup and recovery – never a pleasant topic in the physical server
world – gets even more thorny and problematic in a virtual server world. …

Challenge #4 – Managing End-To-End Service Delivery

I’ve made the case before
that we don’t live in a world anymore where one user uses one
application.  What the user sees is a logical combination of
application services that run on an increasingly complex IT
infrastructure stack.  And IT finds it harder and harder to drive back
to a root cause when there’s a performance or outage that users are
noticing. …
