Vsan Vs Object Storage

Virtual san stores and manages data in the form of flexible data containers called objects.

Vsan vs object storage.

Object storage is the only option that can effectively store this data at scale. What is vmware vsan. 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. Some standard storage protocols such as fcp do not apply to virtual san.

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. Components is the disks of the vm which is vmdk. Object is comprised of multiple components.

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. Virtualized storage or vsan. An object is a logical volume that has its data and metadata distributed and accessed across the entire cluster. The data can be anything you want to store from a family photo to a 400 000 page manual for assembling an aircraft.

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. A software layer sits between the server usually a virtual machine providing an abstracted version of the underlying physical storage. 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.

When you provision a virtual machine on a virtual san datastore virtual san creates an object for each virtual disk. Another component is there which is witness which helps to avoid the split brain scenarios. Simply put virtualized storage refers to the abstraction of storage. Every object contains three things.

Where virtual machine data is stored as an objects. 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. Vsan is an object based storage.
