About Custom Storage Class If your network is 10GbE and configured properly at all points using decent equipment, you can indeed get the same sorts of speeds over iSCSI as you do with an SSD (10GbE == ~1280MB/s, theoretical maximum). There are three types of CSI plugins. 1. The picture below is self-explanatory and what I like is the option to already include the creation of the iSCSI Target which will be associated to the same LUN. In Rancher Launched Kubernetes clusters that store data on iSCSI volumes, you may experience an issue where kubelets fail to automatically connect with iSCSI volumes. In contrast, a block protocol such as iSCSI supports a single client for each volume on the block server. iscsi " # add note here about volume expansion requirements storageClasses. 3 Differences Between NFS and iSCSI NFS and iSCSI provide fundamentally different data sharing semantics.

Using the CSI Topology feature, access to volumes can be limited to a subset of nodes, based on regions and availability zones. 11+), but the code does not rely on any Kubernetes specific calls (WIP to make it k8s agnostic) and should be able. By mapping iSCSI LUNs to iSCSI Targets, client servers can access. For example, for a job that needs an AWS EBS volume, Nomad will tell the controller plugin that it needs a volume to be "published" to the client node, and the controller will make the API calls to AWS to attach the EBS volume to the right EC2.
