What is Evergreen//One?

Evergreen//One is a storage as-a-service (STaaS) platform that unifies on-premises and public cloud storage resources in a single data storage subscription that delivers a true hybrid cloud experience.

People also ask:

1. How does Evergreen//One work?

A one-year commitment to an Evergreen//One subscription includes:

  • A simple subscription for your block, file, and object storage needs
  • Access to Pure1® management tools for monitoring your hybrid cloud environment from a single dashboard
  • 100% consumption-based subscription model that allows you to pay only for the resources you use

Simply choose the service tier that meets your workload and business requirements, scale up and down as needed, and only pay for what you use.​ ​​Deploy your storage resources on-premises in your data center, in a colocation facility, or in the public cloud. Evergreen//One gives you the flexibility to connect to the customers, partners, and ecosystems that deliver the most value. ​Free up your IT resources from day-to-day storage management tasks and enable them to focus on more strategic priorities.​

2. How much does Evergreen//One cost?

Pure offers a simple and transparent pricing model based on flat $/GiB rates for products and services. We routinely update a public MSRP table to help you calculate the cost of your storage subscription. The Evergreen//One pricing model offers improved granularity of service selections for performance and capacity depending on your storage needs.

3. What is storage as a service?

Storage as a service (STaaS) is a data storage business model that delivers capacity and performance resources through a simple subscription. STaaS saves you money through operating expenditure (OPEX) agility. In other words, you pay only for the storage you use, when you use it.

4. What is an SLA for energy efficiency?

An SLA for energy efficiency is a guarantee to deliver a service at no more than a specified watt per unit of measure per tebibyte (TiB). If a customer has purchased STaaS, an energy efficiency SLA from their STaaS provider can detail how much energy is used per array and per unit of data stored, while ensuring adherence to a strict energy usage limit.
