Abstract: Some techniques described herein relate to determining how to optimally store datasets in a multi-tiered storage device with compression. In one example, a method includes assigning, to a data partition of a dataset, a priority based on access patterns of the data partition. Compression data is accessed describing results of compressing a data sample associated with the data partition using multiple compression schemes. Based both on the priority of the data partition and the compression data, a storage tier is determined for storing the data partition in the multi-tiered storage device. Further, based both on the priority of the data partition and the compression data, a compression scheme is determined for compressing the data partition for storage in the multi-tiered storage device. The data partition is compressed using the compression scheme to produce a compressed data partition, and the compressed data partition is stored in the storage tier.

Abstract: A method for dynamic access control in a virtual storage environment is provided. Embodiments include providing, by a component within a cluster of virtual computing instances (VCIs), one or more computing node identifiers associated with the cluster to a management entity associated with a file volume. Embodiments include modifying, by the management entity, an access control list associated with the file volume based on the one or more computing node identifiers. Embodiments include determining, by the component, a configuration change related to the cluster. Embodiments include providing, by the component, based on the configuration change, an updated one or more computing node identifiers associated with the cluster to the management entity. Embodiments include modifying, by the management entity, the access control list associated with the file volume based on the updated one or more computing node identifiers.
