Thanks for the kind words.
I read your post on NMP RR and iooperationslimit=1. Do you have any test data on VMAX? As you can tell from my testing, my PP numbers are much better than RR at 1000. When I take it to 1, the gap disappears. But I understand from your posts and Duncan's that things would be different on multiple hosts, with multiple LUN's.
Unfortunately I am running into time constraints, and I don't think I'll be able to do a huge test with several hosts. Just checking with you to see if there is any data out there. I've got to make a decision really soon on this PPVE purchase.
Great study of multipathing and vSphere…
This came across my path yesterday and is awesome… At a customer, someone did their own testing of PowerPath/VE relative to NMP as they refreshed their EVA to an EMC VMAX. I want to highlight, EMC absolutely supports, and loves the NMP RR behavior, so it’s not that it’s bad, it’s just that th...
Excellent story Chuck! I see so many companies stuck in situations just like this. It really is sad to see rampant incompetence impacting a company. It's even worse when YOU get the blame for it.
I think you handled it perfectly.
The Vendor Beating
We've all seen parents berate their children, and managers berate their employees. It's not pleasant to watch, but it happens. As an employee of a large IT vendor, I've been at the receiving end of a reasonable number of vendor beatings. Occasionally it's richly deserved. But, sometimes,...
VDC's are great. I only wish there was some way to connect them without patching a cable over. Good interview Vaughn.
Cisco Live chat with J Metz of Cisco on FCoE & Putting the Cart Behind the Horse
My Cisco Live misadventures continued with Cisco FCoE product manager J Metz. This was my first time meeting J, a former university professor who these days promotes, evangelizes, and drives the development of FCoE products and technology. I've followed him online for sometime and was pretty ja...
Nice write-up. In addition to the example you give above, I think a reason VMAX is a better fit for some organizations is the criticality of the workload and the SLA's involved.
As reliable as the mid-tier arrays are these days, for some it comes down to whether you are able to tolerate that extra "nine" of downtime or performance degradation. Nines are algorithmically expensive, so only your business can determine what one is worth.
Of VMAX and VNX
A recent tweet from a customer sparked an interesting discussion earlier this week. @chuckhollis What decision making factors do you think are most important for a client deciding between mid-tier and enterprise storage? Great question. I struggled to provide a meaningful answer in 140 chara...
Great post! Thanks for sharing. I've been wondering how FastCache would help one of my SQL workloads.
SQL Server Performance and Virtualization Testing with EMC VNX
Last month I wrote a post about the new virtualized Sharepoint solution using Microsoft Hyper-V on EMC VNX. That particular solution focused on the tiered storage of the VNX and how to use the storage array for both primary production data to storage SQL databases containing active Sharepoint da...

Great presentations Chad. It was nice to get more detailed info on VNX.
3 Big Ideas… and a low-level VNX discussion
Varrow knows how to hold a great event. Their inaugural “Varrow Madness” happened on thursday last week at the majestic Grandover resort in Greensboro, NC. It was attended by about 100 230 customers, and the pantheon of Varrow technology partners, including VMware, EMC, and Cisco. I broke out...
Wow! EMC has their own Stig!

Something awesome this way comes….
For those of you that haven’t seen it yet, Chad’s World Episode one has had it’s second revision posted here. It hast a small update which alludes to something cool coming on Jan 18th, which is now RIGHT AROUND the corner. And yes, you will see episode 2 of Chad’s World (I still feel silly ...
Interesting. What this says to me is that the negative attacks, although a lot less in number, carry a LOT more weight with social media followers.
Take note.
Vendor Blogger Survey
After watching twitter for a bit, I noted that it seemed to me that some vendor folks are very anti-competitor rather than pro-own-company. This is tiresome. Anything any vendor employee says about a competitor is automatically viewed with suspicion and isn't believed. There have been some quit...
Chad:
I sent it over via e-mail. It's one of those documents that's locked away behind their "information firewall". When you get a chance to read it, I would enjoy hearing your thoughts.
Yes, it’s true. EMC really IS #1 for VMware.
I REALLY try to refrain from chest beating – I don’t personally think it’s needed, and furthermore people don’t generally respond well to it. Sometimes it’s hard – as I’m fortunate to have access to reams of data and other information that isn’t widely known – so when I hear a strange claim b...
Good write-up. I hear this out there quite a bit. I think the study you show from ESG is indicative of the current state of IT research these days. I can show you an Aberdeen report that shows almost the exact polar opposite of what the ESG one shows.
Of course the Aberdeen one doesn't specify demographics, or even number of respondents. I do think it illustrates why we all should be as skeptical of these "research" firms as we are vendor marketing. Is there really a difference?

Excellent points Tyler.
The Lure Of Kit Cars
OK, time for a "guy moment" here. All the adult males reading this, be honest -- is it true that at one time in your life you seriously considered building a kit car? I know I did. I looked at the sleek shapes, the ability to pick and choose components -- even the potential of converting a ...
I don't agree that it would be better to buy a car entirely built by one company. BMW uses ZF transmissions. Because ZF makes a fantastic transmission.
As a customer, why do I want BMW to make their own transmissions when they can buy better quality ones cheaper from ZF? I don't.
This whole scenario explains why I am not a huge vBlock fan. I don't believe that an EMC Clariion is the perfect array for every customer, and every application. I don't believe UCS is the perfect server platform for every application. I want the flexibility to choose something else if it will perform better for my particular application.

One must assume that the intent is to extend the economic malaise. There is no other logical explanation.
How to discourage producers from producing
Imagine a company deciding to change its sales compensation plan. Rather than providing incentives for salespeople who achieve difficult quotas, it instead implements a sliding commission rate that declines as sales increase. The most talented salespeople would be the most severely impacted and ...
This is going to be awesome! I enjoyed the Charlotte panel, but tossing another vendor in the pool should help further the conversation.
VMworld 2010 Session 'Storage Super-Heavyweight Challenge' with HP, EMC, and NetApp
Many of you have been asking for the status of the sessions submitted for VMworld by NetApp, our customers and partners. It looks like the VMworld 2010 Content Catalog has been posted. While I haven't received confirmation from John Troyer, it appears the catalog is a work in progress. I make th...
