Hello all ,
I have been running a 3par cluster for some time now and some times I dont feel we have it optimised as well as we could .

we have 4 x10ge using openvswitch soft-slb and 4 peers active on the 3par.

What multipath optimisations have other people been using
defaults {
polling_interval 2
path_selector "round-robin 0"
path_grouping_policy multibus
uid_attribute ID_SERIAL
rr_min_io 100
failback immediate
no_path_retry queue
user_friendly_names yes
}

Cheers D

Hi Dazza76

  • You may wish to disable “delay-ack”
  • Make sure you are using jumbo frames MTU 9000 on the NIC ports (host and SAN) and Switch.
How’s the setup going?
We are investigating attaching a 3Par would be great to hear any feedback.
