3Leaf Systems today announced it has obtained a license for Intel's QuickPath Interconnect, which will allow it to build virtualization support for Intel servers. Previously, the company only had a HyperTransport (define) license and only supported AMD servers.
3Leaf uses a direct communication network between server CPUs so data does not have to go over an Ethernet or Fibre Channel connection. The company makes special virtualization processors for the motherboard to virtualize the CPUs, memory and I/O of the entire datacenter.
The 3Leaf technology breaks down the physical walls of x86 servers and makes their resources available, as needed, across the datacenter. One of the problems in datacenters is one group of servers dedicated to a task might be running at five percent utilization, while another group is maxed out and needs more CPU cycles and more memory.
The concept of dynamic data isn't new with 3Leaf, mainframes have had it for years. It's just that x86 servers never could do it because they lacked the power. "The way the processors used to communicate was too slow to do this," said Jagadeesh. "AMD's HyperTransport interface helped, as does QuickPath."
The other problem was the back end fabric, as he called networking, had too much latency to make it acceptable. Now with Infiniband or 10Gbit Ethernet, such interconnects are possible.
