A Linux MP (AMD/Intel) System will do. The bottle neck is the physical Ram (and the speed of the Ram/memory transferrates) of the server hardware. The user Load 500-1000 Users/a day is easy to handle, do you have an idea howmany users will be "online" synchrounously ? It's IMHO a good idea to plan 16MB of physical Ram for each physical User/synchronously, the Ram amount for each user lowers if there are plenty useres. In this case there should be a "cache configuration optimisation be made" (Try-out). > I've browsed thru and only found some on data volume and log volume, that is Raid 1 > for data volume, Log mode dual, on seperate drives. I'd suggest to use Hardware RAID drives. Depending on the budget my choice for the Harddisk system are: 1. ICP-Vortex SCSI (->http://www.icp-cortex.com ) really good HW-Raidcontrollers, no problems at all. 2. ICP-Vortex SATA 3. 3Ware IDE-Hardware Raid (runns perfectliy in linux, uses cheap IDE harddisks) To my expierience I'd choose a Debian 3.0r1 System using XFS Filesystem for the operating system work, and putting the production Database on a 2nd harddisk system, a 2nd controller. The Database should work on "raw" partitions, to avoid overhead in os-filesystem work. As last option to optimize you can put the LOG spaces to an 3rd Harddisksystem. So we have an idea for a fine server: 4 CPUs (don't forget to tune SapDB for 4 Cpu usage!) 2-4 GB of RAM, more possible if an Opteron is in duty. 2 HW-Raidsystems, hot-plugable disks fast NIC(s) Software: Debian 3.0/r1 (Reason: secure, reliable, fast, working live-update, heavy load proven) Filesystem: XFS with distributed Journaled Logs for optimal OS-PErformance Kernel: Linux 2.4.21-xfs, (2.4.22-xfs if Nvidia Mainboard Chipset and IDE needed) SapDB Debian package is supplied by us. mfG J�rgen automatiX Linux Support Crew - -- J�rgen Sauer - AutomatiX GmbH, +49-4209-4699, [EMAIL PROTECTED] ** ** Das Linux Systemhaus - Service - Support - Server - L�sungen ** ** http://www.automatix.de ICQ: #344389676 ** -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQE/j7VTW7UKI9EqarERAqa7AKCU8L6fG5ZH5lEJlOiFsAblUIa1IQCgml26 nZCmPzuOhLeeJU9Hif83I7U= =7Lit -----END PGP SIGNATURE----- -- MaxDB Discussion Mailing List For list archives: http://lists.mysql.com/maxdb To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
