Vzboost, Vizioncore’s COS secret ?

Ever wondered why vRanger is copying VMDK files via the COS so fast ? Here’s the answer. Someone from Vizioncore showed me this video at the TSX in Nice. The vzboost-vmkmod module is written by a Vizioncore software engineer who studied the original VMFS module code from VMware and rewrote it into the vzboost-vmkmod module. You can take a look at vzboost in action using this link. First you see the original VMware driver running with 280 writes per second after the vzboost driver is loaded the speeds will jump to 639 writes per second.
