+# Additional Volume Setups
+
+In addition to the already implemented described in [run1](../run1), I'd like to focus
+on benchmarking single node for [provided storage solutions](https://cloud.google.com/kubernetes-engine/docs/concepts/storage-overview)
+meaning we don't have to setup our own filesystem in addition.
+
+## Contenders
+
+### Block Storage Persistent Disk
+
+ - Includes filestore (already ready to go for experiment)
+ - [Cloud Volumes Service](https://netapp-trident.readthedocs.io/en/stable-v20.01/kubernetes/operations/tasks/backends/cvs_gcp.html) (requires external service, no)
+ - [Google Compute Engine Persistent Disk](https://cloud.google.com/kubernetes-engine/docs/how-to/persistent-volumes/gce-pd-csi-driver) TODO try this.
+
+## Choices
+
+These are the ones I want to test. Filestore was already tested in [run0](run0) and
+the yamls are included here in [crd](crd). We need to figure out the rest.
+
+### Persistent Volumes
+
+We are going to try a vanilla cluster as described in the [docs](https://cloud.google.com/kubernetes-engine/docs/how-to/persistent-volumes/gce-pd-csi-driver) first:
+
+#### 1. Create Cluster
+
+```bash
+gcloud container clusters create storage-cluster \
+   --addons=GcePersistentDiskCsiDriver \
+  --machine-type=c2d-standard-2
+```
+
+#### 2. Get Storageclass
+
+Get the storage classes available. We will want to prepare files (storage classes) for each.
+
+```bash
+kubectl get sc
+```
+```console
+NAME                     PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
+premium-rwo              pd.csi.storage.gke.io   Delete          WaitForFirstConsumer   true                   2m2s
+standard                 kubernetes.io/gce-pd    Delete          Immediate              true                   2m1s
+standard-rwo (default)   pd.csi.storage.gke.io   Delete          WaitForFirstConsumer   true                   2m1s
+```
+
+Let's create additional ones we can ask for. Note that [we cannot use the c3 type](https://cloud.google.com/kubernetes-engine/docs/how-to/persistent-volumes/gce-pd-csi-driver#unsupported_machine_types).
+
+
+TODO I think I need to [create a persistent disk](https://cloud.google.com/compute/docs/disks/extreme-persistent-disk#provisioning_iops) too.
+This means we can ask for any three of these volumes, and
