new MySQL Server
I would like to get a viewpoint from the members on the following: 1) the amount of $$$ is NOT a consideration Looking at building a MySQL server to handle in-house critical work. Web = page data is generated from the database plus constant inputting of data = and calculation. Application to be run: Red Hat 9.0 PHP4 MySQL 4 Apache 2 SSH I'm looking at the following: 1) IDE RAID5 with 4 x 120GB drives 7200RPM ATA100 2) Sony CDT or AIT tapebackup 3) 2 x 10/100/1000 Intel NIC 4) Intel P4 3GHz CPU 5) 2GB PC3200 ECC Memory Motherboard consists of the following: Socket 478 Intel=AE Pentium=AE 4/Celeron=AE NetBurst 4 x DDR SDRAM PC3200 ECC Registered, 4GB max. 5 PCI, 1 AGP 8x (1.5v only) Highpoint HPT374 UDMA/ATA 133 RAID Broadcom BCM5705 Gigabit Ethernet ATX Now I've worked with the Broadcom NIC and that works great, but I have not = worked with a Highpoint RAID card. Does anyone have good and /or bad = experiences with this card or should I buy a separate card? My other option is to go with a SCSI system using a Adaptec RAID card, = etc. Jon L.

Re: new MySQL Server
I believe I saw something in the mySQL manual about going with a 64 bit system if it was an option because mySQL uses lots of 64 bit data types. So you will see a significant increase in speed with 64 bits versus 32. :: drools at though of Apple w/ 8GB RAM :: :-D -Dan On Sat, 2003-09-20 at 08:11, Jon Miller wrote: I would like to get a viewpoint from the members on the following: 1) the amount of $$$ is NOT a consideration Looking at building a MySQL server to handle in-house critical work.

Help with spec-ing new MySQL server
Hello, I have been asked to spec out a new computer that will act as a dedicated MySQL server for a research cluster (running under RH Linux). To do that, I am trying to find information on the performance trade-offs between multiple processors (2 vs 4), the disk system (IDE vs SCSI; single vs RAID), and the memory system (1 GB, 2 GB, 2 GB). Specifically, is there a point above which you (typically) don't see a significant improvement? Is there a rational upper limit to the amount of physical memory that MySQL can effectively use or benefit from? Does an IDE RAID system significantly improve the database performance? Does SCSI RAID significantly outperform IDE? Should we concentrate on a system with an enormous amount of memory, or a very fast disk system? Based on current usage, I am expecting the database load to float around 200-400 simultaneous connections to a small number of databases (1-10). Each database will have several tables with a couple hundred thousand records each (each table will float between a MB and a GB).

RE: Help with spec-ing new MySQL server
John, Going off the top of my head and what you posted I would suggest a dual processor machine with at least 1 GB of RAM. (Make sure you compile MySQL with threads) SCSI is going to be much faster than IDE. If this is a production machine I would highly recommend SCSI. Finally, I would recommend RAID 0+1 (Striped and mirrored) As that gives you the best overall combination of performance in a database server. If you have to start cutting then you could drop the RAID and one processor and still have a well-performing machine. Next thing you need to think about is how to configure MySQL. Give it as much RAM as you can. If you are using InnoDB tables then check out http://www.innodb.com/ibman.html#InnoDB_tuning for more suggestions. They used to have several versions of my.cnf suggestions (small, medium and large) but I can't seem to find them anymore.
