Announcing AIX 7.3!   

It has been an exciting year of announcements for AIX and Power Systems, starting with the celebration of 35 years of AIX innovation in February, followed by the release of the new IBM Power E1080 server in September.   Today, I am happy to be able to officially announce AIX 7.3, the newest addition to the AIX family!


AIX 7.3 was designed to extend the value of your IBM Power10 server, while also expanding on the industry leading key strengths such as reliability, availability, security, performance that our customers have relied on for the last 35 years.   With continued focus on AIX strategic initiatives including modernizing with open technology, and making sure AIX is ready for both on-prem private cloud deployments and off-prem public cloud solutions, AIX 7.3 will help you make sure your business is hybrid cloud ready.   

With the addition of the Power10 Matrix Math Accelerators (MMA) along with the new IBM OpenXL compilers, and Engineering and Scientific Subroutine Library (ESSL), AIX 7.3 will help you streamline your insights and automation to get the most from your valuable business data by infusing AI workloads into your mission critical data work stream.  Learn more about Enterprise AI with AIX here.
