Re: [PERFORM] Hardware opinions wanted
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I'm working through the aquisition process for a quad Opteron box right now. I'll be benchmarking it against a quad processor p630 as well as a quad Xeon after we get it and posting results here. But that's about a month or two from now. I expect that the results will be strongly in favour of the Opetron, especially the price / performance since the Opteron box is being quoted at about half the price of the p630 systems. One thing you may wish to consider is going with lots of 10kRPM SATA disks instead of 15kRPM SCSI disks. Two companies that I'm aware of offer quad Opteron solutions with SATA raid: http://www.quatopteron.com/ http://alltec.com/home.php Andrew Hammond DBA - Afilias -BEGIN PGP SIGNATURE- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFAvjYKgfzn5SevSpoRAvq0AJkBDXOKL52HXg43mQ6rXe/i9RzFkQCfYQn8 HpHP2U0jvjfYIvihNLFLbzA= =LyqB -END PGP SIGNATURE- ---(end of broadcast)--- TIP 6: Have you searched our list archives? http://archives.postgresql.org

The Opteron was the clear winner. Personally I think that you can't be wrong with the 4-way Opteron. It scales very well and if you don't need the fault tolerance of the pSeries platform, then you should be able to save one or two bucks with opteron way. Btw: If you want to save a few more bucks, then drop the 15k and take 10k drives. They are of almost same speed. Regards, Bjoern ---(end of broadcast)--- TIP 8: explain analyze is your friend
