There are some impressive new scores at storageperformance.org, with the usual crazy configurations of thousands of drives etc.
When looking at $/IOP, make sure you are comparing list price (look at the full disclosure report, that has all the details for each config).
Otherwise, you could get the wrong $/IOP since some vendors have list prices, others show heavy discounting.

With the advent of performance-altering technologies (notice the word choice), storage sizing is just not what it used to be.
I’m writing this post because more and more I see some vendors not using scientific methods to size their solution, instead aiming to reach a price point, hoping the technology will work to achieve the requisite performance (and if it doesn’t, it’s sold anyway, either they can give some free gear to make the problem go away, or the customer can always buy more, right?)

Some of the comments in my previous post asked about $/IOPS and $/TB.
Since SPEC doesn’t require prices to be listed, I did my own analysis.
The NetApp numbers are simply 4x the existing 6240 result, which is what EMC did with their submission, they used 4x separate VNX systems and aggregated the result.

A bit of a controversial title, no?
Allow me to elaborate.
EMC posted a new SPEC SFS result as part of a marketing stunt (which is working, look at what I’m doing – I’m talking about them, if only to clear the air).

It’s that time of the year again. The usual websites are busy with news of the upcoming EMC midrange refresh called VNX. And records being broken.
(NEWSFLASH: Watching the webcast now, the record they kept saying they would break ended up being some guy jumping over a bunch of EMC arrays with a motorcycle – and here I was hoping to see some kind of performance record…)
