ScaleMP announced a new version of its server virtualization for aggregation platform, vSMP Foundation 3.5. The latest version expands support for four-socket systems and adds additional Linux clustering management.
When you think about server virtualization, you normally do so in terms of partitioning or splicing a single larger physical machine into many smaller virtual machines. That technology is fairly common in today's modern IT shops. We partition servers in this way in order to optimize the workload of a single machine, because most modern x86 servers have more capacity than a single application can consume on a daily basis. But what happens when the opposite is true? What happens when you need to optimize the workload demand of an application that requires more processor cores or more memory than a single physical machine has to offer?

That's where ScaleMP comes into play. The company said there are three application domains that require a large VM: applications requiring large amounts of memory, applications requiring lots of CPUs in a shared-memory environment (multithreaded applications), and I/O-intensive applications.
To answer that call, ScaleMP's vSMP Foundation uses a form of server virtualization called high-end virtualization or server virtualization for aggregation. In other words, instead of partitioning a single physical machine into many smaller virtual machines, vSMP Foundation takes multiple x86 physical systems and aggregates them into what appears to be a single virtual x86 machine, delivering an industry-standard, high-end symmetric multiprocessor (SMP) computer.
vSMP Foundation 3.5 currently supports aggregation of up to 128 servers into a single virtual SMP system with up to 64TB of shared memory and up to 1,024 processors (or 8,192 cores). Once loaded into the memory of each of the system boards, vSMP Foundation aggregates the compute, memory, and I/O capabilities of each system and presents a unified virtual system to both the operating system and the applications running above the OS.
"Aggregation provides a virtual machine with the combined power of a collection of servers," said Shai Fultheim, founder and CEO of ScaleMP. "For example, aggregating 10 systems will result in a virtual machine with an order of magnitude more memory and CPU power, compared to physical servers.
