The days of slow and inefficient storage are a thing of the past with the NetApp® AFF A250 all-flash storage array. This state-of-the-art system is an entry-level end-to-end NVMe solution, featuring NVMe SSDs on the back end and NVMe over FC (NVMe/FC) host connectivity on the front end. Compared to its predecessor, the AFF A220 array, the AFF A250 array is simpler, faster, and more efficient, delivering a whopping 45% increase in performance and 33% more storage efficiency. With the AFF A250, you can accelerate demanding applications, consolidate more workloads in a shared environment, and reduce your data center costs. In addition, it supports lightning-fast client connectivity on an entry-class system, such as 32Gb FC and 25GbE. The AFF A250 is built on the latest NetApp ONTAP® release, ONTAP 9.8, which improves cloud integration and simplifies data management across the hybrid cloud. Best of all, you won't have to pay extra for these new benefits; the price of the AFF A250 is similar to that of the previous model, the AFF A220.

To meet the demand for rapid, secure, and uninterrupted data access, agile and efficient IT infrastructure is essential for organizations that rely on data-driven decision-making.. To undertake an effective IT transformation, it is crucial to modernize your infrastructure by implementing all-flash storage, which can enhance the speed and responsiveness of critical business applications. However, first-generation flash systems may not be able to deliver the extreme performance required by new workloads such as data analytics, artificial intelligence (AI), and deep learning (DL). Furthermore, as more organizations adopt a "cloud-first" strategy, they need enterprise-grade data services that can function across both on-premises data centers and the cloud. Therefore, modern all-flash arrays should provide robust data services, integrated data protection, seamless scalability, and elevated levels of performance, as well as comprehensive application and cloud integration. NetApp® AFF A-Series systems, powered by ONTAP, offer cloud-connected flash storage solutions that enable IT departments to leverage modern cloud technologies to transform their infrastructure quickly and support data-driven strategies. These systems deliver industry-leading performance, superior flexibility, and best-in-class data services and cloud integration to help organizations accelerate, manage, and protect their business-critical data in the hybrid cloud.
• AFF is relied upon by a diverse customer base, spanning from midsize businesses to large enterprises.
• Streamline operations with effortless data management, both on-premises and in the cloud.
• Enhance the performance of existing and emerging applications.
• Ensure the continuous availability, protection, and security of business-critical data.

The AFF A-Series systems, whether they are entry-level or high-end, are designed to support end-to-end NVMe technologies. This includes NVMe-attached SSDs, as well as front-end host connectivity for both NVMe over Fibre Channel (NVMe/FC) and NVMe over TCP (NVMe/TCP). As a result, these systems offer the lowest latency available for an enterprise all-flash array, making them an excellent option for running the most demanding workloads and AI/DL applications. By performing a straightforward software upgrade to the modern NVMe/FC or NVMe/TCP SAN infrastructure, you can run more workloads with faster response times, without any disruption or data migration.
