Link: The Platform Matters More Than Ever, The Operating System Less So

“Windows Server 2019 is a case in point, and going through the highlights shows it. Back in the day, when a new Windows Server release came out, everyone was obsessed about its scalability and reliability and how it compared to alternatives such IBM i, a slew of Unix variants (including IBM’s own AIX), and the IBM mainframe platforms: VSE, OS/390, and VM. We all dug through the manuals to see how many processors or cores or threads it could span, how much memory it could address, what the impact of SMP or NUMA clustering was on performance, how the I/O was architected to match whatever new gizmos were on the PCI-Express bus. No one really worries about these things. It is a given that any operating system will exploit hardware, and that most hardware is more than enough for most customers. This is not just an IBM i thing. Certain customers, to be sure, can make use of as many cores Intel can cram into a two-socket server, but for most companies, they are nowhere near the top bin parts and they have much less capable processors running at a lot lower cost and with plenty of excess capacity. It doesn’t matter if it is Windows Server or Linux. The basic workhorse server does not look that different from a Power8 or Power9 machine, and in many IBM i shops, there is far less compute dedicated to IBM i on a single instance than on a Windows Server or Linux machine. The database jobs that most IBM i shops have are fairly modest.”
