　　StackThat is, the storage areas for variables allocated by the compiler when needed and automatically cleared when not needed. The variables are usually local variables and function parameters. In a process, the user stack is located at the top of the user's virtual address space, and the compiler uses it to call functions. Like the heap, the user stack can be dynamically expanded and reduced during program execution. 　　HeapThat is, the memory block

For example, if you need to save the images obtained from the network to the local database as the cached data, and the

VMware storage is not just as simple as mapping LUNs to physical servers. VMware vsphere allows system administrators to create multiple virtual machines on one physical machine. Potential hypervisor and vsphere ESXi enable the guest virtual machine to simultaneously use both internal and external storage devices. This article will discuss the basics of building sans on vsphere and what administrators consi
