What is a datastore?
DataStores in VMware vSphere are storage containers for files. They could be located on a local server hard drive or across the network on a SAN. DataStores hide the specifics of each storage device and provide a uniform model for storing virtual machine files. DataStores are used to hold: virtual machine files, templates, and ISO images. They can Read More…
ESXI storage introduction
ESXi hosts support host-level storage virtualization, which logically abstracts the physical storage layer from virtual machines. The following storage technologies are supported by ESXi: Direct-attached storage internal hard disks or external storage systems attached to the ESXi host through a direct connection using protocols such as SAS or SATA. ThisRead More…
