[..]I've had great success with a 6 disk setup: 2 disks for the filesystem, mirrored
2 disks for the LOG, software mirrored in raw mode 2 disks for the DATA, software mirrored in raw mode
[..]/proc/ide/hdf/model: ST340016A Disk /dev/hdf: 16 heads, 63 sectors, 77545 cylinders
/proc/ide/hdg/model: ST340016A Disk /dev/hdg: 255 heads, 63 sectors, 4865 cylinders
partitions: LOG: hdf1 256MB hdg1 256MB
Flemming,
thank you for the detailed description! I've been waiting for some sort of recommendation quite a while - but SAPDB's answers were usually very
vague...
What strikes me that you only have a 256MB partition on your hdf and hdg drives. Is there any particular reason for this "waste" of disk space?
Have you ever evaluated performance differences regarding SCSI vs. IDE drives, hardare vs. software raid, raw vs. cooked (ext3) filesystem?
Arne
PS.: Is there going to be an 'official' recommentation by SAP / MySQL concerning disk/raid/volumes/fs setup?
