What are VMware vVols?

Описание: VMware vVols, or VMware Virtual Volumes, is a storage management framework introduced by VMware to enhance storage integration and management for virtualized environments. Unlike traditional storage approaches that manage storage at the LUN (Logical Unit Number) level, vVols operate at the virtual machine (VM) or virtual disk level, providing finer granularity and more flexibility in storage provisioning, management, and data services.

Key features and benefits of VMware vVols include:

Granular Management: vVols allow storage policies to be defined and applied at the VM level, enabling finer control over data services such as snapshots, replication, and encryption. This granular management simplifies provisioning and reduces manual configuration.

Improved Data Services: With vVols, storage arrays can expose their native data services directly to VMs, making it easier to leverage features like deduplication, compression, and snapshots at the VM level.

Dynamic Provisioning: Traditional storage provisioning involves pre-allocating storage resources, often leading to inefficiencies. vVols enable dynamic provisioning, where storage is allocated on-demand as VMs require it, optimizing storage utilization.

Automation and Policy-Based Management: vVols integrate with VMware's policy-based management framework, enabling administrators to define storage policies based on performance, availability, and other requirements. VMs automatically inherit and apply these policies, reducing manual intervention.

Improved Performance: vVols can enhance performance by leveraging the underlying storage array's capabilities, such as quality of service (QoS) and intelligent caching.

Simplified Troubleshooting: vVols provide better visibility into VM-level statistics and health, making it easier to identify and troubleshoot issues.

Multivendor Support: VMware vVols is designed as an industry-standard framework, allowing storage vendors to develop compliant implementations. This encourages interoperability and choice for organizations using different storage arrays.

VMware vVols represent a shift in storage management paradigms, aligning storage operations more closely with the virtualized environment's needs. By simplifying management, improving data services, and enabling dynamic provisioning, vVols contribute to a more efficient, scalable, and agile virtualization infrastructure.
