Dear Linux Hackers,
Have we not finished changing the 'best' way to have persistent naming and security attributes for disk devices? Seriously, just when we thought it was great to put the "uid", "gid" and "mode" specifications for disk devices into /etc/multipath.conf, then it gets once again deprecated in favour of udev. This push and pull game has to stop!
Yours Faithfully
All Oracle Users

I need your help!
One of the things that I have struggled to get data for in my storage research is the latency of the interface between server and storage device. It's easy to get numbers for the actual storage device, but the latency numbers for the interface are typically not published. That's a shame, because the latency at this piece of the architecture is going to become increasingly important as we move wholesale to SSD. I don't mean flash specifically here, I mean semiconductor storage devices, of which flash is a component. But this article isn't about that, except by implication, it's just about the piece of wet string that connects storage devices to servers (the transport).

We've just booked the first European venue for the Understanding Storage Masterclass. I will be presenting the Masterclass on April 24/25 2012 at Prospero House in London, tickets are available HERE.
I'm pretty excited to host this training session in my home country, and I hope to see you there!
This year at the UKOUG conference the OakTable Network will be trying something a little different. In addition to the usual 45-60 minute presentations during the conference, and the special OakTable Sunday event immediately prior to the conference, we will also be trialling a new concept - the OAK Talk. Anybody that has watched a TED Talk, or was even more fortunate to attend, will be immediately familiar with this concept - very short, concise and entertaining presentations.
The OAK Talks will be presented every day during the conference in a rapid fire fashion. Each lunchtime the 'Unconference' area of the exhibit hall will be occupied by the OakTable team to deliver FIVE presentations within the space of an hour. The presentations will be different each day and will feature the following presenters:
We will be tweeting further news using the hashtag #OakTalks.
Hope to see some of you there, it promises to be an interesting spin on technical presentation style.
This is a post about the importance of appropriately simplistic architectures. I frequently get involved with the creation of full-stack architectures, and in particular the architecture of the database platform. There are some golden rules when designing such systems, but one of the most important ones is to keep the design as simple as possible. This isn't a performance enhancement, this is an availability enhancement. Complexity, after all, is the enemy of availability.
