This allows for the partitioning or combination of the full storage capacity as needed.
Vsan vs object storage.
Simply put virtualized storage refers to the abstraction of storage.
Where virtual machine data is stored as an objects.
When you provision a virtual machine on a virtual san datastore virtual san creates an object for each virtual disk.
Object is comprised of multiple components.
A software layer sits between the server usually a virtual machine providing an abstracted version of the underlying physical storage.
Components is the disks of the vm which is vmdk.
What is vmware vsan.
The data can be anything you want to store from a family photo to a 400 000 page manual for assembling an aircraft.
The vmware vsan 7 update 1 release added the vsan data persistence platform that enables software vendors to add plugins to complement vsan s file and block storage.
As an example let s take that same 600gb virtual disk and apply the vsan default storage policy which uses the raid 1 mirroring failure tolerance method and has the number of failures to tolerate set to one.
Every object contains three things.
Vsan is an object based storage.
Virtual san is highly.
Some standard storage protocols such as fcp do not apply to virtual san.
An object is a logical volume that has its data and metadata distributed and accessed across the entire cluster.
Object storage also referred to as object based storage is a general term that refers to the way in which we organize and work with units of storage called objects.
Object storage is the only option that can effectively store this data at scale.
These rules affect the number of components that make up an object.
Virtual san stores and manages data in the form of flexible data containers called objects.
Virtualized storage or vsan.
The 600gb object with three components will be mirrored on another host.
Virtual san has no concept of traditional storage volumes based on luns or nfs shares although the iscsi target service uses luns to enable an initiator on a remote host to transport block level data to a storage device in the virtual san cluster.
Vsan is enterprise class storage virtualization software that when combined with vsphere allows you to manage compute and storage with a single platform with vsan you can reduce the cost and complexity of traditional storage and take the easiest path to hyperconverged infrastructure and hybrid cloud evolve to an integrated hyperconverged infrastructure hci solution.
