Top Storage Virtualization Providers

Storage virtualization streamlines storage administrators’ management of all storage solutions within an enterprise infrastructure, allowing them to more efficiently tier data for applications. Virtual storage solutions also help enterprises ensure that data is still available in case of failure and increases storage scalability

Storage virtualization decouples logical storage from physical storage, so logical storage can be accessed across a storage network, through a management console. In a virtualized storage environment, data from disparate storage sources is pooled and visible to administrators.

VMware vSAN

VMware’s storage virtualization solution integrates with vSphere, VMware’s cloud VMware logo. virtualization software package. Hybrid cluster deployments pool resources from both magnetic drives and flash devices; all-flash clusters use entirely flash devices. Admins can use virtual machine storage policies to set requirements for storage within the infrastructure. 

vSAN administrators are able to view the health of their storage infrastructure through performance charts for clusters, virtual disks, physical disks, hosts, and VMs. vSAN allows block-level deduplication and compression, so admins can eliminate redundant data and create more space for disk groups. 

Key differentiators

  • Integration with vSphere
  • Multiple options for cluster deployments
  • Health check features and performance charts

Features of storage virtualization

Storage virtualization solutions typically include the following features: 

  • Pool of storage resources from multiple locations: including different drives, such as hard disk drives (HDDs) and solid-state drives (SSDs). Because the virtual infrastructure decouples the access location from the underlying physical storage, administrators are able to view stored data in one place.
  • Support for multiple storage protocols: Enterprises that use legacy protocols, like SAS, as well as modern storage, like NVMe, benefit from storage virtualization platforms that permit both. 
  • Replication: Storage virtualization solutions often have replication capabilities, such as mirroring and snapshots. 
  • Single management console for multiple storage solutions: A storage virtualization platform allows administrators to manage the entire storage infrastructure, including disparate stores of data, from one location. 

Benefits of storage virtualization 

Advantages of storage virtualization platforms include: 

  • Centralization: A single solution for managing multiple storage systems improves admin visibility. 
  • Better opportunities for data analytics: Because all data is visible through the virtual pool, more data is available to be analyzed. This decreases data silos that happen when multiple data sources are analyzed separately, and it can increase the accuracy of insights drawn from data.
  • Reduced vendor lock-in: increases the variety of hardware and storage solutions The nature of virtualization means that different servers and operating systems can run in the same infrastructure and still pool their storage resources. Because storage virtualization customers aren’t locked in to the same vendor, they also have more financial flexibility. 
  • Decreased hardware costs: Because virtual machines allow more resources to be hosted on a server, enterprises pay less for hardware.
