Unfortunatly the Controllers in the three SUN-Servers do not support 300 GByte SCSI-Drives, so I have to continue with the Raid-5 of 16x 76 GByte. Oh yes, I have started the PostgreSQL in 03/2000 with 7x 18 GByte and never had problems with Raid-5. Suggestions? Please note, that in the coming year, my PostgreSQL will increase to at least 900 GByte (text only) and the corresponding FileServer with original Documents and additional Infos from 1,6 TByte to 28 TByte. OK, I was thinking of a Server-Farm of small AMD64FX or Opteron 140 with two 300 GByte SCSI-Drives in Hardware Raid-1, and then installing 6-8 Systems running in Cluster, but I have no experience in such systems... And the price will explode... (Hardware recommandations?) Are there any acceptable Tyan Opteron 140 Mainboards with SCSI Raid-5 onboard? - It should work with Debian GNU/Linux Sarge(amd64). Oh yes, I have seeen that 300 GByte Drives are around 1200 Euro/drive. So a "simpel" server will eat up at least 4200 Euro. Any suggestions are welcome.
