OS: SLES 11 SP 3
file systems: ext3
there is ‘discard’ option introduced with ext4 file system and I found a lot of online resources recommending ‘discard’ options for SSD disks.
No similar option is available with ext3 file system.
Is there any recommendations available to get max from SSD disk using SLES11/ext3 file systems. Any best practices ?

Hi
For the 3.x and greater kernels, you can use discard and the fstrim
utility is available. Check is disk alignment.
Another other option is the elevator and setting the swappiness down
depending on how much system ram.

‘discard’ option is not available with ext3 file systems. Though fstrim is available with SLE 11 SP 3.
noop or elavator which one is recommended for SSD disk ? Yes swappiness is already set to 20.
Thanks for your help and recommendations.
