Depending on what one wants to do with such a server, getting software stacks to run on it is important. For example, Oracle doesn't compile Java for PowerPC/Linux (no surprise there), one has to get the IBM J9 version. As long as one is using mostly Open Source software, it should be possible to build a version for PowerPC, but commercial software may be harder to find for PowerPC/Linux.
When people release new product lines based on PowerPC these days, it's news.
Personally, I'm glad to see PowerPC still going strong. IMO it's a much better instruction set than x86 or ARM. Now we just need a development board with Raspberry Pi pricing.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
