DCIG is pleased to announce the DCIG 2020-21 Enterprise All-Flash Array Buyer’s Guide. This Buyer’s Guide helps organizations assess the enterprise all-flash array marketplace and identify which array may be the best fit for their environment.
The Buyer’s Guide includes data sheets for 17 enterprises’ all-flash array series that achieved rankings of Recommended and Excellent. Nine vendors offer these products, including Dell EMC, Hitachi Vantara, HPE, Huawei, IBM, NetApp, Pure Storage, Kaminario (now Silk), and Tintri.
Enterprises replacing their legacy storage systems have a transformational data center and business opportunity. The data storage landscape has changed dramatically over the last several years. For any business looking to refresh its storage infrastructure, these changes create a whole new world of possibilities.
All-Flash Array Innovation Goes Beyond Performance
The current generation of enterprise all-flash arrays may deliver order-of-magnitude improvements over legacy storage across multiple vectors, including latency, capacity, and density. Beyond performance claims, these arrays transform the storage ownership experience along several vectors, to include:
- Sophisticated storage analytics with proactive technical support to maximize availability and application performance
- New acquisition and deployment options, including storage-as-a-service and in the public cloud
- Automation of provisioning and ongoing storage management tasks
Advantages of Upgrading to the All-Flash Arrays Presented in this Buyer’s Guide
Any organization that has not yet adopted an all-flash storage infrastructure for its active workloads operates at a competitive disadvantage. The enterprise all-flash storage arrays presented in this Guide can:
- Help organizations move faster
- Make existing applications run faster even as data sets grow
- Accelerate application development
- Enable IT departments to say, “Yes” to new workloads and then get those new workloads producing results in record time
- Drive down data center operating costs
