When storage capacity reaches the multiple petabyte level, maintaining high performance access is a challenge.
Engadget estimates it at 100 petabytes of storage on a single rack (1 Petabyte = 1000 TB).
INFINIDAT started selling its flagship InfiniBoxA product in 2014 and most recently started shipping the Infinidat Backup Appliance.A single InfiniBox is capable of storing over 5 petabytes of data with a smaller carbon footprint than most petabyte scale arrays,and provides industry-leading performance and reliability.Unlike traditional enterprise solutions that rely on expensive flash hardware for performance, InfiniBox takes a software-centric approach, using machine learning algorithms to extract the highest performance and reliability out of standard hardware.
