Comment: virtualze on mainframe (Score 1) 457
What surprises me is that I see a lot of advice on Vmware, very little on KVM/qemu (which performs better btw) and none on HyperV (that makes sense) nor on mainframe. Mainframe has been doing virtualization for decades and is lightyears ahead in I/O, segmentation, auditing, redundancy, reliability, performance, accuracy etc.
The latest offering from IBM scales to 300 virtualized servers (on a z114 in the cheapest config, realisticly @ $100K). Redundancy is built in the hardware. CRC is done at the hardware level. Mind you, these systems are designed to run at 100% utilization non-stop. Not this if higher than 15% you should run physical c(r)ap from VMware.
