# EbsStorageInfo

EBS volume information.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/cluster.ts`](https://github.com/aws/aws-cdk/blob/v2.274.0-alpha.0/packages/@aws-cdk/aws-msk-alpha/lib/cluster.ts#L181)

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as msk_alpha from '@aws-cdk/aws-msk-alpha';
import { aws_kms as interfaces_kms } from 'aws-cdk-lib/interfaces';

declare const keyRef: interfaces_kms.IKeyRef;
const ebsStorageInfo: msk_alpha.EbsStorageInfo = {
  encryptionKey: keyRef,
  volumeSize: 123,
};
```

## Properties

- `encryptionKey`: [IKeyRef](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_kms.IKeyRef.html) — The AWS KMS key for encrypting data at rest.

  **Default:** Uses AWS managed CMK (aws/kafka)

- `volumeSize`: number = 1000 — The size in GiB of the EBS volume for the data drive on each broker node.
