IBM Announcement : Preview z/VM 6.3

Today IBM is launching a preview for their operating systems. Let's first have a look at z/VM : 'Preview: IBM z/VM 6.3 - Smarter Computing with efficiency at scale (ZP13-0027)'.

The highlights ?

"To address pressure on memory resources, z/VM V6.3 supports 1 TB of real memory, which may increase server consolidation ratios and continues to provide support for more virtual servers than any other platform in a single footprint".

"To address your increasing workload demands for processor cycles and for quicker access to memory, z/VM V6.3 delivers HiperDispatch function that can improve workload throughput by optimizing processor cache utilization. HiperDispatch attempts to redispatch a virtual server repeatedly on the same physical CPU, or on a collection of physically adjacent CPUs, to increase the chances of obtaining data from the processor cache, instead of incurring time delays by having to go to main memory for data".
