You're spot on ... again!
Every time I engage with a customer about his Cloud initiative, I first verify my customer ability to be flexible and agile, then I verify their processes and make recommendations. There is a lot of education here obviously.
Only once the customer fully understands the concepts of Cloud and agrees to change his mindset and his processes then we can talk technology eventually.
It is People, Process and Technology ... In that order with People being my highest priority.
In his keynote, Pat Gelsinger introduced the idea of Brave IT. This exactly my feeling when I talk to customers trying to drive innovations for their wealth and growth. This is also exhausting because you're sometimes facing walls of status-quo ...
Never mind, path to the Cloud is a journey, we will get there anyway :)

Grr – make your pick. Do you want “Open Everything” or “Agility”?
Sometimes, customers and partners frustrate me. There, I said it :-) I’m sure the reverse is also true – I bet I/we can be frustrating too :-) People… “Choice” is good. But “Choice” can also be the enemy of “Agility”. Specifically, with a ton of variation, moving forward gets really hard, an...
Hi Vaughn. Would that be feasible the performance engineers post the IOmeter Configuration Files (.ICF) they used to benchmark this environment?
They can be recreated from the report though, but that would be great if that is available online...

New vSphere 4.1 Report: Measuring SAN & NAS Performance
NetApp and VMware performance engineering have completed a new storage performance technical report, TR-3916. This new report provides the relative I/O performance available from SAN and NAS storage protocols with vSphere 4.1 and a NetApp FAS array. The testing in the new TR-3916 is a leap forw...
Count me in!
Got awesome customers who might be happy to share their storage workload profiles.
Thanks for the freebie. I hope you can deliver to Belgium :)
Using VMware? Want more perf? Help me help you.
So, everyone wants more performance, always. As I mentioned in yesterday’s post, it’s REALLY hard to generate a “VMware IO workload”, and most benchmarks out there aren’t that good at the IO part of a VMware benchmark. Even VMmark 2.0 which is a great CPU/memory tile-based, mixed workload ben...
Am I reading that correctly... You guys gave away a VNXe...
OMG that's definitely more valuable than the regular goodies :)
VMware Partner Exchange 2011–Recap and Content
UPDATED Feb 23/2001 8:51am – Fixed the PEX deck link. Well – another VMware PEX has come and gone, and PEX 2011 was a doozy This is actually one of my favorite events of the year – it’s more intimate in some ways than VMworld. Plus, you see people who are in an important sense - all in the b...
This is awesome guys! Keep them coming...
Just one quick remark, I would love to see the episodes in an higher resolution.
Cheers,

Chad’s World – World Debut….
It’s so ridiculous, it’s cringe-worthy :-) Click on the below to see the pilot episode of “Chad’s World” with my friend and colleague (and head vSpecialist) Wade O’Harrow. First, while I have an ego (doesn’t everyone?)… It isn’t SO big that I suggested this idea :-) Any ego that I DID have ...
I had the same issue once. Since then I always recommend customers to format with a 8MB block size whatever the datatstore size is.
And something very important, keep it consistent across the datastores for many reasons, several cited in above comments...
For those who don't understand interactions between block size, file size and sub block, there is a good blog post available at http://wp.me/pvGaC-wP (DeinosCloud)

Having trouble importing a big OVF/OVA?
Have been working on a couple long nerdy posts, so today’s is a short one… Last week was the “Managers GeekWeek”, and one part of our Kobayashi Maru scenario involved doing some creative stuff with an “as of yet” not released into the wild EMC VSA. Importing the VSA kept failing for some reas...
Wouldn't that be great if storage vendors come out with a standard management protocol to exchange information about storage status, health, perf, etc. of their devices with any compatible clients such vSphere or other storage devices too?
Networking industry have standards like SNMP, IGMP. I expect storage industry can make it as well, no!?

SIOC and strange warnings – a reflection on the future…
So – recently, there was a set of EMC/VMware cases (these will apply across the storage community) that triggered my colleagues Scott Drummonds (here) and Scott Lowe (here) to comment. The scoop is that SIOC looks at the datastore as if it contains a fixed amount of IOps that can be “sunk”, an...
Anyone has a link to benchmark tests?
I'm curious how this rackable 'PC' with a lot of disks does perform, especially the IOPS you can get out of it :)
Thx,

Iomega ix12 – the ix4’s bigger brother…
Today – the Iomega folks released the ix12-300r, which you can read here. This is the slow ramp up to a busy announcement week at EMC world… :-) Of course just like all iomega ix family it will be on the VMware HCL (not there today, but testing done, will be on there as it refreshes). While...
Excellent spirit Chad!
And to anyone who has some spare CPU cycles to give away, World Community Grid (www.worldcommunitygrid.org) is another way to fight against those nasty diseases!
A little EMC/NetApp Fun – to help cure cancer…
Folks – we spend so much time fighting, so much seriousness in things that in the end, while important aren’t as important of the lives of people, in particular the lives of children. A friend and colleague at NetApp let me know they were doing a drive for St. Baldricks – a campaign where people...
Good to hear you are fine now. Keep up posted if your excellent articles.
Where's Vaughn?
You may have noticed that outside of last week's Cisco NetApp VMware alliance launch I haven’t been writing with much frequency. The reason for the recent lack of posts were due to a misbehaving gallbladder and subsequent Cholecystectomy. I didn’t realize I had a flaky gallbladder until I had m...
Oops look like this blog does't like brackets...
@Dave Mc
You could tweak down the VMs monopolizing storage I/O by setting a registry key that will decrease the queue depth.
i.e. for LSI FC add the following reg key:
HKLM\SYSTEM\CurrentControlSet\Services\Lsi_fc\Parameters\Device\MaximumTargetQueueDepth ,0x40 (64 decimal)
64 is the default, test with 32 for instance...
/MAXTAGS=nnn added to Driver Parameters is a common one but not recognized by all vendors...

100,000 I/O Operations Per Second, One ESX Host
The performance of I/O is critical to achieving good overall performance on enterprise applications. Workloads like transaction processing systems, web applications, and mail servers are sensitive to the throughput and latency of the I/O subsystem. In order for VMware ESX to run these applicatio...

My thought is that current disks, with moving parts, are the last bastion we have (had!) to take down before going to infiniband. As usual the former technology pays for the new one, thus regular disk as we know them, still have some years to live before completely phasing out. Let see what will happen in 2010 :)
Wow – 1TB consumer-grade SSDs hit the street.
Anyone doubting that 2010 will be an inflection point on solid-state storage? We now have consumer-grade 40GB drive at $115 (talked about here), and a 1TB drive at $3.5K. http://www.theinquirer.net/inquirer/news/1562474/one-terabyte-ssd-hits-shops While these are consumer drives, and are missi...
