Reliability, Availability, and Serviceability (RAS)
Since its release in June of 2014 IBM has continued to expand the POWER8 line. With 4-core models and higher end enterprise versions out for a while now it is a good time to update our original article on POWER7 vs POWER8, the differences between them and what it means to for businesses and end-users.
In the time between our first article and today, the range of CPW the POWER8 machines are capable of has expanded significantly (from 359,000-911,000) to 10,300 on the 4-core S814 systems, to over 2,000,000 CPW on the enterprise class E880. What is CPW? CPW is IBM’s benchmarking score for how efficiently an IBM i system can handle heavy database intensive loads. This number can be used to determine the relative ability of individual IBM systems to efficiently handle a given workload.
However, CPW is not the only factor that POWER8 improves upon over POWER7 systems. A major consideration for many, and likely a make or break factor for some, is the cost of maintenance and support for your system. With the myriad of innovations IBM has implemented into the POWER8 systems, the power available at all support tiers has increased significantly. Which means businesses can now get more power than ever before, with lower maintenance
In addition to CPW and maintenance costs, here are a few other things to take into consideration for upgrading ANY system for your business:
IBM was the first to use this phrase in describing the robustness of their hardware, and IBM continues to improve upon this aspect in every succeeding iteration of their systems. The POWER8 is no different. With additional built in error checking compared to earlier POWER designs and more internal monitoring POWER8 systems are the most reliable POWER systems to date.
Throughout the 1990s the AS/400 was the pre-eminent workhorse of America's IT infrastructure. The line was refreshed in 2000 and renamed the eServer iSeries and was again renamed the System i in 2008. This generation of midrange servers was phased out in 2008, to be replaced by the IBM Power Systems range in 2008.
The AS/400 and its immediate descendants were designed to last and built solidly, so a good number of them are still in excellent working order and playing their part in fulfilling the needs of America's small- and medium-sized enterprises. But times change, and an AS/400 from the early 90s may no longer be up to the job of coping with the sheer quantity of information storage and processing required in 2012. If a business is considering upgrading, there are a number of options they can consider.
