When would you use SAN with MySQL ?

Posted by peter |

One question which comes up very often is when one should use SAN with MySQL, which is especially popular among people got used to Oracle or other Enterprise database systems which are quite commonly deployed on SAN.

My question in such case is always what exactly are you trying to get by using SAN ?

Percona Performance Conference CFP deadline extended

Posted by Baron Schwartz |

Even though we haven’t yet gotten a schedule online, we’re still accepting proposals for the Percona Performance Conference.

As a teaser, let me just share one accepted proposal with you: Cary Millsap. If you are even vaguely involved with Oracle, you should know who he is. He is one of the world’s foremost authorities on Oracle performance. Cary will be giving a technology-agnostic session on Performance Instrumentation Beyond What You Do Now. Don’t miss this one.

But that’s only the beginning; there’s a lot more to come. There are good reasons why we created our own conference specifically on performance, and if you attend, you’ll see for yourself. In the meantime, you can submit your own proposal. Oh, and sign up as an attendee, too. We haven’t gotten the attendee list online either, but we will soon.

Debian / Ubuntu Percona builds

Posted by Vadim |

We had too many requests for deb builds of Percona releases so I could not ignore that and added scripts to build binaries on our Ubuntu 8.10 box. It's going to be only 64bit releases (32bit is dead, isn't it?), and I tested binaries on Debian Lenny system and it seems working fine.

So I prepared binaries for our Build13 (which I actually did not announce to not spam PlanetMySQL a lot, I will figure out another channel for announcements), and you can get it there http://www.percona.com/mysql/5.0.77-b13/deb/, and your feedback is welcome!

As for changes for Build13 it contains InnoDB Data Dictionary restriction patch, which I mentioned before (http://www.mysqlperformanceblog.com/2009/02/11/limiting-innodb-data-dictionary/).

Speaking of deb binaries I tried to keep it compatible with native deb binaries, but I had to make some changes:

1. There was strange configure parameters

CODE:
  1. --without-embedded-server \
  2.                 --with-embedded-server \
  3.                 --with-embedded-privilege-control \

which I was not sure how to interpret, so I removed any mentioning of embedded server as 5.0 actually is not supposed to work in embedded mode and our patches can't be compiled in this case.

2. I removed NDB cluster engine from builds, we have not tested combination of our patches with NDB so I really do not know how it works together.

Enjoy!
