Here I blogged about the speed of PVC provisioning of PVCs with Trident and SolidFire.

If you're interested in BeeGFS CSI and Nomad CSI (as opposed to Kubernetes), check this post.

Lately there's a new "concurrency" feature in NetApp Trident CSI.

To enable it, install with --enable-concurrency.

sean@s159:~/trident-installer$ ./tridentctl -n trident install -h | grep conc
      --enable-concurrency                      Enable concurrency for Trident's controller **TECH PREVIEW**

Let's see how well it works!

I installed Trident CSI 25.10 and then prepared my backend definition.

$ ./tridentctl -n trident create backend -f backend-solidfire.json  
Error: could not create backend: backend type solidfire-san is not yet supported by concurrent Trident (400 Bad Request)
command terminated with exit code 1
Error: exit status 1

Noice…

For what it's worth, creating volumes in a loop in "standard" mode may now be faster than it used to.

I don't have the old result (from the post at the top), but just creating 10 volumes takes less than 3 seconds.

The post at the top included "binding", which is async and likely independent of storage (the regular iSCSI rescan-and-login steps), and NGINX pod startup.

So, no concurrency for the fast SolidFire backend, but maybe a bit faster PVC provisioning compared to before.
