Hi all,
From http://code.kx.com/wiki/Reference/pardottxt, it says - “if also, the partitions in par.txt are on separate disks, this means that each thread gets its own disk or disks, and there should be no disk contention (i.e. not more than one thread issuing commands to any one disk). Ideally, there should be one disk per thread. Note that this works best where the disks have fully independent access paths cpu-disk controller-disk, but may be of little use with shared access due to disk contention, e.g. with SAN/RAID”
Now say I have a RAID of 1TB. Will there be any benefits if I split it into e.g. 5 disk partitions , each of 200GB, and mount them to different mount points for use in par.txt ? From what was said above, it seems there is no benefit at all. It would be equivalent to having 1 single partition of 1TB and create 5 directories out of it ?
Thanks.
