Dell internal app. Only Dell can provide it and only Dell can decrypt the output.
Seems some people have cracked it.

Pretty sure Dell's T&Cs prohibit selling the solution and their lawyers will come after anyone who tries it.
Now, if the soloution just ended up being distributed outside the control of anyone one individual, they would have a hard time. DPACK is a major tool in their sales arsenal for products. Maybe the engineering guys will re-write DPACK to counter it.

That's just a never ending battle.

As the software and video game industries have learned, you cannot copy protect your software, ever. It's a never ending game of whack-a-mole.
Apparently, this is all he had to do. Little bit of PHP.
<?php $contents = file_get_contents("7daycapturePPP2.iokit"); $newlines = 0; for($i = 0; $i < strlen($contents); $i++) { if( ord($contents[$i]) == 10) { $newlines++; if($newlines == 2) { $original_header = substr($contents, 0, $i + 1); $contents = substr_replace($contents, "", 0, $i + 1); break; } } } echo $original_header; echo zlib_decode($contents); ?> -

Pretty much!

So NTG has both the DPACK installers and the decryption software, so no need to talk to Dell at all?
@Minion-Queen ?No, you always have to "get the DPACK tool" from Dell. And Dell always has to physical decrypt it. But you get to choose if a 3-2-1 capacity planner sales person provides you with the results or if an NTG engineer does. In one case the results are presented as just capacity numbers for scaling your nodes and SAN. In the other it is a generic assessment that will help to look at broad needs including architecture and system design.

https://www.freelancer.co.uk/projects/C-Programming/Decode-the-Dell-dpack-file/I'm not surprised. I doubt Dell goes to great lengths to lock it down.

Not if that guy is based in the UK. And why would someone pay for it if Dell provides the results for free?

I don't consider a sales pitch free, And I'm wondering since they went to the efforts of doing this free thing for you, will they put the high pressure on the sales pitch?

That's a good point. My only counter to that is that.... nearly anyone willing to go through the effort of avoiding that sales pitch and using a solution like this to work around it likely will not be swayed by the sales pitch. Maybe I'm wrong, but I am guessing that that is true.
It is a pretty high pressure process, from what I am told.

From my initial conversation with the Dell enterprise sales rep he intimated that "we may disagree on certain issues, but at the end of the day be able to work together to come up with the best solution that fits our needs".

Sure, but in the real world we've talked to literally hundreds of companies that have gone through that process and not one reports ANY variation for the inverted pyramid of doom being shoved down their throats relentlessly even after they've shown that it would be costly and reckless to do so and in no way meets their needs. We've yet to have anyone report back that their rep had ever even asked for the necessary information to begin determining their needs either.
If you want to go through this process and see if you can get a different result, feel free. But so far the reports are 100% that the IPOD is pushed as the only option even when clearly it is the worst one.

It is insanely high pressure. Dell called me and when I told them "No" I got an intro call from CDW and a second vendor. They just happen to find my information and were pitching the same system the the Dell rep was... odd.
They all recommended two cheap Dell servers and a low level SAN for a crazy price.
-
That is universally the story that I have been told and what has been reported online. Every case, no exceptions.

The problem is... that could be true or it could be an example of how high pressure that they are: that they tell you that what they are doing is to find something that fits your needs. This is both what low pressure as well as high pressure would look like.
Did they ask you your needs? The business needs, that is? Or are they only looking at capacity? If they don't do a huge amount of business investigation, why do they know what does or does not suite your needs?

@scottalanmiller I must say that folks on this blog have gone out of their way to patiently help me understand the perils of IPOD. I am not even considering implementing this as a possible solution. My only reason for contacting Dell and obtaining DPACK access was to utilize their tools.
Taking into consideration that DPACK revealed my IOPS are not very high, is the 730xd overkill OR is it still the best solution due to the large amount of usable storage I'd have available for my VMs?

R720xd and R730xd have the same IOPS, or so close that it doesn't matter. It's CPU that varies between them.

Aside from the initial phone call regarding DPACK I haven't spoke to the Dell rep since 23 October. When I did speak to the rep he didn't spend much time learning about our current\future business needs; he was relying on DPACK to give him any information.
If our developers/programmers had their way our environment would be:
VM 01 - SQL Server 2005 (to be used only for database migrations from 2005 to SQL 20xx)
VM 02 - SQL Server 2008 (to be used only for database migrations from 2008 {some customers installed 2008 instead of waiting for 2008 R2 and the SQL migration tools are very picky} to SQL 20xx)Physical Server 01 - SQL Server 2008 R2
Physical Server 02 - SQL Server 2012
Physical Server 03 - SQL Server 2014
Physical Server 04 - Oracle 11g
Physical Server 05 - Oracle 12cSQL Server and Oracle are perfectly capable of running in a Hyper-V environment...provided everything is meticulously planned out in advance.
The developers are afraid of running SQL and Oracle in a virtualized environment because our current VMs are very inefficient. They do not seem to hear me when I say "I agree, our current virtual environment is awful. How do you propose we change the mindset of an owner who believes a high-end desktop is perfectly acceptable to be used as a server?"
It's very difficult to educate someone when they know more than you do about everything and wants you to know that.

That's what we've been saying. That's the hard sell. The DPACK tells him only capacity planning data. ALL of the important stuff comes from you, not the DPACK. So an IT Pro would have no means of even remotely providing you a recommendation from the DPACK alone. He's purely a salesman, not an engineer. He is only sizing his sales pitch, not doing anything to consider what is applicable to you or your business.
