IBM i resiliency compared to Windows and Oracle

Posted by Dave Kravitt

ibm_i_resiliencyThe start of a brand-new year seems like a good time to take a hard look at the platforms that form the IT backbone running your business. Is IBM i still a good solution? While there are many reasons for leaning toward IBM i as the platform of choice, let’s focus on what I would consider the most basic and necessary characteristic for any system, yet it does not seem to be talked about as much as it should. Resiliency. How does IBM i compare with what else is out there? 

Fortunately, there’s a study that makes it easier to do a side-by-side comparison. IBM commissioned a report from International Technology Group (ITG) studying underlying IT system resiliency – a critical factor for business continuity and disaster recovery – and comparing the IBM i platform with Microsoft’s Windows Server Failover Cluster for X86 servers and Oracle’s Exadata parallel database systems. The results will pleasantly surprise many IT managers and maybe even convert some skeptics. 

For its study, ITG collected financial and operational data from 60 companies and created six composite company profiles, broken into two broad industry categories: supply chain companies (i.e., an industrial distributor, retail chain, and auto parts manufacturer) and financial services (i.e., an insurance company, a retail bank and a financial services firm). The study focused on hardware and software platform outages rather than application-level issues and looked at business costs dues specifically to system downtime and business risks associated with it.  

What the study revealed was a significant savings with IBM i which suffered an astonishing 90 PERCENT LESS business outages than Windows server clusters and 71 percent less than Oracle Exadata systems, based on both planned and unplanned outages of less than three hours. The risks of business damage associated with outages were similarly significant – 93 percent less risk with IBM i than clustered Windows servers and 73 percent less than Oracle Exadata infrastructure. Overall, that translates into 8.3 times higher business costs for Windows users and 3.4 times higher for Oracle environments compared to IBM i. This study, while conducted on large enterprises averaging several thousand employees each, is also pertinent for SMBs who have just as much at stake when it comes to dealing with business continuity and disaster recovery but have less resources and IT redundancy to weather outages.
