In this video, learn how storage commands flow in a traditional storage solution and contrast that with the storage path used by Virtual SAN 6.7 (vSAN). Learn why shared storage is required for many vSphere features like vMotion and DRS, and how VMs are broken down into objects and stored across multiple ESXi hosts.
- [Rick] In this video, … we'll compare virtual machine storage … using vSAN versus the traditional approach … of purchasing a physical hardware storage array. … And so let's start with the very basic elements of this. … Here we see a diagram where on the left in purple, … we've got a virtual machine, … and just like memory, just like CPU, … the virtual machine doesn't actually have … physical storage hardware, it doesn't have physical CPUs, … it doesn't have physical memory, … it's accessing a shared resource. … And for storage traditionally we've had something called … a VMFS data store or maybe an NFS data store. … So from the perspective … of my Windows virtual machine here on the left, … this VM needs to see the storage hardware, … we'll give it a virtual SCSI controller, … it will basically trick windows into thinking … that it actually has a physical storage adapter … by giving it a driver for a virtual SCSI controller. … So here we see the virtual SCSI controller … that's being presented to our Windows operating system, …
