Getting to grips with VIOS, part 6: redundancy and resilience
Here’s a big difference between VIOS and VMWare and the like: Intel servers only run one instance of virtualisation software. If the software needs patching with a reboot, then the entire system with all its VMs has to be taken down. With VIO Server, however, you can run multiple instances on the same server.
Getting to grips with Virtual I/O server, part four
Following on from last month's article, in which I introduced you to some basic VIOS CLI functions and hopefully removed some of the IBM i pro’s inherent fear of AIX and VIO, it’s time to get down to the nitty-gritty of VIOS.
Tech Tips: Getting to grips with Virtual I/O Server, part 3
VIO Server is a superset of AIX. What does this mean? Quite simply, that your VIOS LPARs are AIX LPARs with some additional functionality. From an IBM i perspective, I find that most people want to avoid the command-line interface (CLI) if at all possible. Let me try and ease you into it.
Opinion: PowerVM leads to IBM i resurgence
There have been numerous reports of a resurgence of IBM i in recent months and much of this has been down to the fantastic pricing and performance of the Power 7 systems. Who would have thought a few years ago that we could get a 23,000 CPW system in a 2U format for less than £20,000? We need to be careful, though, when we see some of the headlines bandied about by IBM as, quite often, the figures they show are for all Power 7 systems sold. Without doubt, the majority of Power 7 sales are boxes which are sold with AIX as the only licensed operating system – no IBM i or Power Linux in sight.
