To pick on one point, although this should set an expectation for the rest of the post. You were no where near being first with a production ready VSA, it's complete bunk, you're not even on the VMware compatibility matrix with a VSA, can't see your partner Fujitsu there either.

Thanks for the comment, I admit the following paragraph could have been written with more clarity.

Thus I revised the original content from:

By smallest of installations, did you know that NetApp is the only storage vendor that ships a production workload capable software-based virtual storage appliance (VSA)? Oh, and keep in mind that the VSA comes with the same functionality and management toolset as found in our Enterprise-class storage arrays.

To:

"By smallest of installations, did you know that NetApp is the only storage vendor that ships a production workload capable software-based virtual storage appliance (VSA), and the VSA ships with the same functionality and management toolset as found in our Enterprise-class storage arrays?"

I believe the revised section best communicates the point I was trying to communicate.

Thanks for the feedback.

Good blog Vaughn. I'll share this in the morning for some training with my reps.

Hi Vaughn,

I don't have a problem with the grammar, it's the use of the word ONLY.

The original point was, and still is, that you aren't the only storage vendor shipping a production workload capable software-based (VSA)as you state.

Far from it, you were late to the party, don't ship it yourselves as it's through an OEM agreement and it's not even qualified on the VMware HCL. FalconStor, HP LeftHand and StorMagic appear to be the leaders in this field, so the use of ONLY is misleading at best. http://goo.gl/IyKFx

I must admit I had some difficulty with your original assertion as it was focused on a single sentence in a paragraph and your concerns were stated based on taking the sentence out of context.

While it was frustrating, I edited the sentence for clarity.

The half of the paragraph you ignored and are now spinning out of context is "and the VSA ships with the same functionality and management toolset as found in our Enterprise-class storage arrays?"

Are you suggesting that this is available from the Lefthand VSA?

Can you please elaborate on the points of integration which spans the Lefthand VSA, EVA, XP, and 3Par array?

Hey Vaughn - sorry, I've been busy this week at our HP Summit (analyst conference) and had no time to comment on this. The issue I think John is raising (and I still don't see it addressed) is your claim to be first with VSA. You very well know that HP LeftHand has had our VSA for several years. So to say you're first -- when in fact the NetApp VSA isn't on the VMware hardware compatability list -- is false. If you really want to fix the blog post to embrace that truth, then you should delete the bit that says "that NetApp is the only storage vendor that ships a production workload capable software-based virtual storage appliance (VSA)".

Your latest comments to John about integration of VSA with all of HP's arrays is simply a red herring. Since our P4000 can span to multiple nodes (have heard of customers with more than 30 nodes), customers aren't asking us to integrate VSA with the rest of our arrays. And not only does our VSA include all the same features (thin provisioning, local and remote replication, etc) as our P4000, but we don't charge extra licensing fees to get any of that.

I know you're a straight up guy and I've always appreciated that about you but you aren't first with a VSA and its not even close.

Customers can try a full featured trial of our HP VSA. All they need is a VM (VMware or Hyper-V) to install it on and DAS drives. If you haven't already, you should check it out: http://www.hp.com/go/TryVSA.

I have a question about performance. Does netapp write performance degrade in any way when snapshots or replication is used. The reason I ask is because one of your competitors can lose as much as 90% of *write* performance when snapshots and replication is used. It is an undocumented but very real phenomenon (and we can duplicate this issue on several of their products). We generally use cifs and often write large files (as much as 1GB in size) so this is a real problem.

@Calvin - Thanks for sharing your thoughts. I've never claimed that NetApp offered the first VSA, but rather that we offer the first VSA that offers the same functionality, management tools, and points of integration as our enterprise line of arrays... In other words, NetApp offers a unified storage one which hardware is merely a means to scale even if the hardware is virtual.

@Bumped - Thanks for sharing. I can understand your concerns. I'd suggest that all storage arrays differ in their ability to provide performance or functionality. NetApp arrays do not lose performance (even though our competitors will say otherwise) with snapshots and our performance actually increases with deduplication. See:
