CVO == Cloud Volumes Ontap, the software version of OnTap that you can run in the
various CSP's (Cloud Service Providers) aka GCP, AWS, Azure
PD == Persistent Disk, what GCP (Google Compute Platform) calls its, uh, persistent disks.
And to answer Jeffs question, we've not done any CVO testing in GCP, so I can't
answer the throughput questions.
We have found that, in general, the VM Instance type that hosts the CVO instances matters,
since the Instance type also determines networking connectivity.
Disk type (in this case GCP PDs) matters, too; I'd test with Local SSD to see where
that gets you.
Lastly, Throughput is dependent on workload, which determines the IO pattern.
Maybe create an FIO config that generates traffic close to what you expect, and
use that to drive various CVO configurations.
