HEllo Team ,

I have configured Cinder Block Storage , in Kilo Version of OpenStack. This is connected to an external Storage via NFS. I wanted to know , to have a improved throughput , on the block device connected to Instances , are there any tuning parameter in Cinder. I understand most of the thing depends on NFS and Storage Device connected, however just wanted to check if in OpenStack we can workout anything at Cinder's Configuration.

Hello amit-g, depending on the storage there are parameter you can set. The cinder nfs driver allows via the nfs_mount_options to set specific mount parameters. Please read here your documentation of your NFS storage for the optimal parameter. A second place for tuning NFS is on the compute host itself for example by increasing for the sunrpc.tcp_slot_table_entries. But also here, check with the storage vendor what is the optimal value. And a last small tuning parameter is the mtu size of your network. Higher mtu sizes need less network transactions.
