### SIG Storage

[SIG Storage][] is responsible for storage and volume plugin components.

For the 1.8 release, SIG Storage extended the Kubernetes storage API. In addition to providing simple
volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and

  `apiserver_request_latencies`
  `apiserver_request_latencies_summary`
  `apiserver_dropped_requests`
  `etcd_request_latencies_summary`
  `apiserver_storage_transformation_latencies_microseconds`
  `apiserver_storage_data_key_generation_latencies_microseconds`
  `apiserver_storage_transformation_failures_total`
  ([#83837](https://github.com/kubernetes/kubernetes/pull/83837), [@RainbowMango](https://github.com/RainbowMango))

Improvements in Windows Server version 1803 also bring new storage functionality to Kubernetes v1.11, including:

* Volume mounts for ConfigMap and Secret
* Flexvolume plugins for SMB and iSCSI storage are also available out-of-tree at [Microsoft/K8s-Storage-Plugins](https://github.com/Microsoft/K8s-Storage-Plugins)
