6 1.Storage Design 1.iMportance of Storage Design a Although design choices at the server layer can make the vsphere environment relatively more or less optimal, design choices for shared resources such as networking and storage can sometimes make the difference between virtualization success and failure This is especially true for storage because of its critical role u Storage design choices remain important regardless of whether you are using storage area networks(SANs), which present shared storage as disks or logical units( LUNS); network attached storage(NAS), which presents shared storage as remotely accessed file systems; or a converged storage infrastructure using local server disks such as VSAN You can create a shared storage design that lowers the cost and increases the efficiency, performance, availability, and flexibility of your vSphere environment 河南中医药大学/阮晓龙/13938213680/htp/cloudxg.hactcm.edu.cn/http:/www5ucwebcn
