7 leading storage area network products and vendors

Before selecting a SAN product, learn which features seven market-leading storage vendors provide organizations of all sizes and how they distinguish their products.

Choosing a storage area network can be a daunting task when comparing products and trying to understand their differences. IT decision-makers must consider a range of factors, including scalability, performance, availability, management and data protection.

Here, we examine the following storage area network products:

  • Dell EMC PowerMax and PowerStore
  • Hewlett Packard Enterprise (HPE) Primera and Nimble
  • Hitachi Vantara Virtual Storage Platform (VSP)
  • IBM FlashSystem
  • Infinidat InfiniBox
  • NetApp All Flash FAS (AFF)
  • Pure Storage FlashArray

These storage devices target organizations of various sizes and support a wide range of workloads. Although this isn't an exhaustive list of storage area network vendors or products, it provides a good starting point for understanding many of the enterprise storage issues to consider when evaluating SANs.

Note that none of the vendors profiled here provide pricing or licensing information. Contact the vendor or reseller directly for more information.
