PowerVM Hypervisor Gets Active Memory Sharing
June 15, 2009 Timothy Prickett Morgan
I’ll admit it. I like hardware, and I like to learn about new hardware features first. But in an increasingly virtualized computing environment, many of the cooler functions are not, strictly speaking, being implemented in hardware, but rather deep in the hypervisor and system microcode. And so it is with one neat–and little discussed–feature that was just announced by IBM for logical partitions on Power-based servers called active memory sharing. The PowerVM server virtualization hypervisor has been able to carve up as well as gang up chunks of processing, memory, and I/O capacity into logical servers long since before it |
