Feature Request - Allow Configuring Volume Limits Per Node

[iyashu]

As of today, gcp doesn't provides static per volume qos guarantees with mounting multiple volumes per node. See Multiple disks attached to a single VM instance section of user documentation. It poses a challenge for hosting stateful workloads on large multi tenant clusters where io performance (throughput/iops) of existing volumes gets affected with mounting of new volume on same node. In order to practically inhibit this effect, we're thinking of limiting no. of volumes per node using CSI volume limit feature graduated in K8s v1.17. I see the csi driver currently limits 127 volumes per node as per the limits defined by gcp on vm.

Will it possible to introduce some configurable parameters to further limit volumes per node?

(1) per-volume IO provisioning is available with newer hyperdisk products which are supported by this driver.

(2) Ironically enough, hyperdisk is complicating the disk limits question, as it has different limits per SKU and per machine type. So this issue is still useful.

For those following, note that hyperdisk avoids these performance problems for the most part by allowing per-volume IO provisioning.
