If it's that critical, you would be wise to go buy a hardware RAID controller. > could anyone give me some pointer , or suggest me > if its advisable to use RAID 1 with database servers. Probably not a bad idea, with hardware; the controller should be able to stream the data across both disks without slowing down writes. Software-based RAID may show slower performance as it must process the command streams for *both* disks in the OS instead of offloading that task to the controller... although if the disks are SCSI with a decent SCSI card that should be minimal. Note that if you're looking for a system you can hotswap, you will probably need to go SCSI in any case; I'm not aware of any hotswap-capable IDE RAID systems. -kgd -- Money is overrated. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
