10Gb Etherent vo virtualnom pocitaci

Clanok, pojednavajuci o vykone VMware virtualizovaneho sietoveho adaptera vmxnet3, hovori:

Line Rate 10GigE

Howie Xu, Director of R&D for VMkernel IO remarked recently that after talking with a few customers, many are still unaware we can achieve line rate 10GigE performance on ESX 3.5. Read “10Gbps Networking Performance on ESX 3.5u1” posted on VMware’s network technology resources page.

The story only gets better with vSphere 4 and ESX 4 with the new Intel Nehalem processors. Initial tests from engineering show a staggering 30Gbps throughput.

Na druhej strane treba mysliet na to, ze vmxnet3 nieje podporovany pre VMware Fault Tolerance:

VMware FT cannot be enabled on a virtual machine using either the VMXNET3 or PVSCSI devices; vCenter Server will simply report an error that the network interface or disk controller isn’t supported for VMware FT.
