In pursuit of reducing cost and improving energy-efficiency, organizations are committed to enhancing their IT operations while simultaneously fulfilling performance and capacity demands. With the increasing maturity and availability of quad-level cell (QLC) flash technology, organizations are discovering its performance is ideal for workloads like AI/ML, analytics, data lakes, ERP, and shared object files.
QLC’s affordable price compared to triple-level cell (TLC) media offers a significant advantage. Customers seeking to update their IT infrastructure from HDD to flash, no longer desire to pay a premium for sub-millisecond performance when it comes to non-mission-critical workloads.
Organizations are also progressively seeking seamless cloud connectivity options, enabling them to establish a flexible hybrid cloud infrastructure that effectively caters to their evolving IT requirements.
The implementation of Lenovo ThinkSystem DG Series All-Flash systems enables customers to realize these objectives by effectively diminishing data center expenses through an eco-friendly and highly efficient alternative to hybrid flash and HDD systems.
The Solution
Based on cutting-edge NVMe and QLC flash technology, Lenovo ThinkSystem DG Series systems offer an exceptional solution for companies of all sizes requiring significant storage capacity within a minimal physical footprint.
An innovative hybrid cloud IT infrastructure empowers customers to streamline and unify data management seamlessly across both cloud and on-premises environments, meeting business requirements and attaining a competitive advantage. Through the implementation of Lenovo ThinkSystem DG Series systems, customers can optimize performance while simultaneously minimizing overall storage expenses.
This is achieved by intelligently tiering cold data to the cloud, allowing organizations to allocate flash storage for frequently accessed data while conserving energy. Along with cloud integration capabilities, customers can effortlessly connect to multiple cloud platforms, enabling access to an expanded range of data services, including backup, caching, and disaster recovery.
Simplified data management and monitoring
Harnessing the unrivaled capabilities of DG Series system unified data management software, Lenovo ThinkSystem DG Series systems offer unparalleled flexibility, allowing customers the ability to move workloads across SAN, NAS, and object storage, utilizing their data on-premises or in the cloud.
