Production storage needs new benchmarks

Dragster Benchmarking I’ve ranted on this more than once. Benchmarks are 99% of the time utter bull… and tell you nothing about what the solution’s real possibilities are, let alone what they mean to your environment. The dragster benchmarks (i.e. SPC-1) are just a show-off competition with little to no value to you. Allow me to bring up a couple of points why; Generally speaking the dragster benchmark is based on 100% 4k-reads. Let me assure you that there is not a single system out there – certainly not yours – that does 100% 4k reads, let alone 4k in

My London Tech Week – 2 ducks in a row

I love London. Well, I like spending time in the UK in general anyhow but London is still a special place. Maybe it’s because it’s the only place in the world where I actually use public transportation (the Underground) without the feeling I need to kill people. If it wasn’t so ridiculously expensive I’d spend a lot more time there or even move. TECH.UNPLUGGED – April 22nd So no need to say I like going back whenever I have a reason. This time I have two! First of all I will be speaking at TECH.UNPLUGGED on april 22nd. Tech.Unplugged is

The Podcasting Setup

2 years ago I wrote my “mobile studio” post where I shared my 3-angle-camera-in-a-backpack setup. Almost every item in that backpack has been replaced by now so I may have to do an update to that post one day. More recently (since September 2014) I have shifted my focus to audio in favour of our new Podcast In Tech We Trust. So here’s my current audio setup; Podcasting at Home Early on, even before starting with the first recording I knew that audio quality is key to a succesful podcast. So I wanted to have a good microphone. After some research

So now you’re a vExpert?

aToday you’ll see plenty of blogposts about the vExpert 2015 nominations. I am proud to say I’ve got a hat-trick now, being recognized as one for the 3rd year in a row. Instead of just dancing around with the certificate in your/my hand, I urge you to now be grateful with that piece of paper and go do something with it! Go earn another one. But as you already know how to do that, here’s my message to your employer! You are a Startup I think if you are a startup in the VMware realm, you should have at least

vSphere 6 NFS4.1 does not include parallel striping!

Oh how happy are we that VMware FINALLY decided to add support for NFS4.1 especially since the NFS3 client’s major problem has always been single-session connectivity. HOWEVER; going over Chris Wahl’s – extensive – coverage on this news item I did miss a key ingredient we were actually waiting for in NFS4.1: support for pNFS (parallel NFS). Chris mentions the following improvements from vSphere 5.5 to 6: Authentication with Kerberos In-band, mandatory, and stateful server side locking Session trunking (true NFS multipathing) Greater error recovery So what does this session trunking do for us and what not?  I tried to simplify the story

Snowflakes and Buzzword Bingo

It’s been a while but I’m back with another marketing rant! Some of you may already know my Fooled By Marketing Metrics which is probalbly a series I am most proud of and I feel I got some more up my sleeves somewhere in the future. But I am a Snowflake One of my activities is helping startups explain their technology to all types of audiences. Where in the market do they fit, what is their true unique selling point, where do they differentiate themselves? And every single time in those conversations there is someone at the table trying to tell me how UNIQUE
