VMware Generation 6: VMware Genx6

VMware has finally announced the VMware’s 6th generation virtualization  software in month of Feb 2015 though GA is not announced(When writing blog).  From the very first release of vCenter in 2004. VMware has climbed the height of success and leading the market with most stabilized and advanced product made in the world of Virtualization. Eric Siebert in his blog collected all the stages of VMware History, can be found @ VMware release.

With my previous blog VMWARE VSPHERE 6: WHAT TO EXPECT “VMWARE DORAEMON”  not completely but few component where seen in Beta release like FT.   Not saying that VMware has considered my blog but it was a technology where we has not seen any improvement from  past few years.

VMware vSphere 6.0 Walkthroughs

VMware has team collected vSphere 6.0 related feature and created web sliding presentation which walk through features like vCenter Server Install, vCenter Server Upgrades, vSphere Data Protection and vSphere Replication.

As VMware updated more items are going to lineup, lets see approach is simple and innovative. How it grows down the line.!/vsphere-6-0
