9.10.2009 von pit.

Jonathan Corbet presented a informative presentation about the recent linux kernel work. It was held at the 11′th realtime Linux workshop, and offers some insides and statements not always presented in the normal press, like from 2.6.27 -> 2.6.31++ rough timeframe (October 9, 2008 to September 18, 2009) 48,000 changesets was merged by 2,500 developers and 400 employers. This result is that the kernel grew by 2.5 million lines, or better 140 changesets merged per day and 7267 lines of code added every day. But he also depicts some major functionality added by each version and why it’s needed. paired with some funny pictures a nice walk through. The other papers from the conference are also a good read, take a look at them by yourself

storage

23.9.2008 von pit.

The Register just posted an article about storage vendors claiming as usual the best storage array’s for Oracle DB. They actually made a failure by linking to Pillar instead of pillardata. I looked recently at Pillardata, they were founded with Lary Ellison backing them. Nevertheless they promise very good utilisation values and builtin QOS via the Axiom box. They use SATA drives and the performnace numbers they mention look quit well. recently they also introduced a smaller axiom box (300) for SME market. I don’t have actual price information, but I like the concept of higher utilisation. another box to look at is Atrato’s Velocity 1000. EMC’s DMX-4 is definitly in a different pricerange. They provide whitepapers with excellent numbers, but I remember that storagemojo explained the SSD products they actually use in more detail. He’s actually one of the consultants who talks about the numbers and offers (updated) pricelists. I follow his blog frequently
