echo 1024 > /sys/block/sda/queue/nr_requests
echo deadline > /sys/block/sda/queue/scheduler
blockdev --setra 16384 /dev/sda

Currently, the following is set:
cat /sys/block/sda/queue/max_sectors_kb
128
cat /sys/block/sda/queue/nr_requests
128
cat /sys/block/sda/queue/scheduler
noop anticipatory [deadline] cfq
blockdev --getra /dev/sda
256

So for me it seems, that the parameters nr_requests and blockdev --setra must be "optimized".

Is this right, and how can I achieve it? I haven't discovered native shell access yet :-) Current build of DSS: 6.0up50.8101.4786 64bit.

Thanks in advance,
Tim

First we recommend you to update to a newer build rather than up50.build 4786, you can find new builds at: http://www.open-e.com/account/products-and-updates/

For the Shell access, it is not available for end users, but you can open a ticket and send us your request, and we can do it through remote support (RSS), for more details:
