Vsan is an object based storage.
Vsan vs object storage.
This allows for the partitioning or combination of the full storage capacity as needed.
Another component is there which is witness which helps to avoid the split brain scenarios.
A software layer sits between the server usually a virtual machine providing an abstracted version of the underlying physical storage.
An object is a logical volume that has its data and metadata distributed and accessed across the entire 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.
What is vmware vsan.
Virtualized storage or vsan.
Object is comprised of multiple components.
Object storage is the only option that can effectively store this data at scale.
Initially the data persistence platform supports dell emc objectscale and object storage from cloudian and minio and datastax s apache casandra based database as a service.
Simply put virtualized storage refers to the abstraction of storage.
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.
These rules affect the number of components that make up an object.
For additional overviews on object storage read our previous blog post in this series object storage vs file storage for a clearer side by side comparison of block storage vs object storage take a look at the table below.
Virtual san stores and manages data in the form of flexible data containers called objects.
Where virtual machine data is stored as an objects.
Every object contains three things.
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.
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.
Virtual san is highly.
The 600gb object with three components will be mirrored on another host.
Components is the disks of the vm which is vmdk.
Some standard storage protocols such as fcp do not apply to virtual san.
