[id="rosa-sdpolicy-encrytpted-at-rest-pv_{context}"]

EBS volumes that are used for PVs are encrypted-at-rest by default.

[id="rosa-sdpolicy-block-storage_{context}"]
|
|
== Block storage (RWO)
|
|
Persistent volumes (PVs) are backed by Amazon Elastic Block Store (Amazon EBS), which is Read-Write-Once.
|
|
|
|
PVs can be attached only to a single node at a time and are specific to the availability zone in which they were provisioned. However, PVs can be attached to any node in the availability zone.
|
|
|
|
Each cloud provider has its own limits for how many PVs can be attached to a single node. See link:https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/volume_limits.html#instance-type-volume-limits[AWS instance type limits] for details.
|
|

|
== Shared Storage (RWX)

|
|
|
The AWS CSI Driver can be used to provide RWX support for
