February 18th, 2009 • Comments Off on OpenNebula becomes part of Ubuntu Server
OpenNebula is now part of the Ubuntu Server distribution. Great news, hope to see other products there also in near future. On the development blog of the team is a nice entry about using open nebula on Ubuntu: http://blog.dsa-research.org/?p=130 The title might be a little bit misleading though…
Also Borja, a former collegaue of mine, got a new version of Haizea announced: http://blog.dsa-research.org/?p=132
December 5th, 2008 • Comments Off on My first SSD drive
After ordering my first Solid State Drive on Tuesday, it arrived on Thursday and today was the day I first tried it. It’s a patriot 64GB Warp v2 drive. And I got it for a reasonable price. Here is a nice picture of the drive. It’s quite light and looks nice, but that is my opinion.
About speed: You can feel the performance increase, and if you look at the numbers the increase is quite impressive. The systems boots twice as fast as before, applications launch faster. Although I must admit that the Intel disc might be faster. Here is the output of hdparm:
Timing cached reads: 1768 MB in 2.00 seconds = 884.39 MB/sec
Timing buffered disk reads: 121 MB in 3.00 seconds = 40.66 MB/sec
Timing cached reads: 1660 MB in 2.00 seconds = 830.30 MB/sec
Timing buffered disk reads: 278 MB in 3.02 seconds = 92.07 MB/sec
The noice reduction is also very good – if the fan is off, you hear nothing, and by nothing I mean nothing. You here only your own typing 🙂
Also the power consumption seems to be much better – in normal mode I can use my notebook 45 minuter longer.
Only negative points are the size of the disc and sometimes the performance is rapidly down for some reason, I have to investigate that further. But for now it was a real good deal!
November 26th, 2008 • Comments Off on Doing it the cloud computing way
Sun has many cloud computing initiatives e.g. network.com. Playing only a underpart is the work done in the RESERVOIR project. RESERVOIR stands for Resources and Services Virtualization without Barriers and is part of the Framework 7 program of the European Union.
Sun is part of this RESERVOIR project and provides great technologies to the project. Besides working on standards for upcoming Cloud Computing frameworks Sun will
- setup and configure the Sun Grid Engine so it is able to run in Cloud Computing environments
- Develop a application container which allows it to handle Java based applications the Cloud way.
The first part is pretty straight forward, while the second part involves more software development. The goal is it to provide a application container which allows the deployment of different kind of Java applications. Those services should then be managed e.g. based upon predefined SLA definitions. Service can then be started, migrated, suspended, consolidate/distributed (if more instance are running) and stopped.
Sun is therefor developing the Virtual Java Service Container with the project name Floccus 🙂 More details are coming up.
