Once upon a time there was a data center filled with racks of physical servers. Thanks to hypervisors such as VMware ESX it was possible to virtualize these systems and run them as virtual machines, using less hardware. This had a lot of advantages in terms of compute efficiency, ease of management and deployment/DR agility.
To enable many of the hypervisor features such as VMotion, HA and DRS, the data of the virtual machine had to be located on a shared storage system. This had an extra benefit: it’s easier to hand out pieces of a big pool of shared storage, than to predict capacity requirements for 100’s of individual servers. Some servers might need a lot of capacity (file servers), some might need just enough for an OS and maybe a web server application. This meant that the move to centralized storage was also beneficial from a capacity allocation perspective.

I’m excited to announce I’ll be attending Storage Field Day 12! During the event we’ll talk storage technology for three days, starting on March 8th. There’s an impressive line-up of companies and delegates gathering in Silicon Valley and of course we’ll live stream the presentations for the folks back home, who can pitch in over Twitter. Did I mention the line-up of companies already? Oh boy!

I can’t recall the last storage system installation that didn’t have some amount of solid state drives in its configuration. And for good reason: we’re rapidly getting used to the performance benefits of SSD technology. Faster applications usually result in real business value. The doctor treating patients can get his paperwork done faster and thus has time for more patients in a day. Or the batch job processing customer mailing lists or CGI renderings completes sooner, giving you a faster time to market.
To reduce the application wait times even further, solid state drives need to be able to achieve even lower latencies. Just reducing the media latency won’t cut it anymore: the software component in the chain needs to catch up. Intel is doing just that with Storage Performance Development Kit (SPDK).

Storage Field Day 11 is taking place on October 5th to 7th in Silicon Valley, and I’m delighted to report: I’ll be one of the delegates again. In fact, this will be my 5th event! Wouldn’t it be awesome if British Airways reads this blog and hands me some champagne to celebrate as soon as we’re in the air…
The Tech Field Days are organized by GestaltIT and follow an efficient concept. A number of companies are invited to present to a number of picked individuals (delegates) and the 2 hour sessions are broadcasted live over the interwebs. The sessions are very interactive: delegates will be asking questions throughout these presentations. People back at home can ask their questions on Twitter (don’t forget the hashtag, which is #SFD11 for this event), and usually one of the delegates will pick it up and voice it towards the presenters.

Woohoo: I will be attending Storage Field Day 8! The 8th edition is held from October 20th till the 23rd in the same location as always: Silicon Valley, CA, (USA, Earth, etc). I’m very excited to return: Storage Field Day 7 was a big success and this time around it shouldn’t be any different. The line-up of presenting companies is impressive: I’ve met some of them at previous Storage Field Days and there’s a couple of new names that I’ve been really looking forward to meet.
