The maximum number of components per host limit is 9000. Objects that make up the VM stored in vSAN include VMDKs, VM swap object, VM namespace, VM snapshot/delta disk object, etc.Ĭomponents are pieces of the VM objects that are stored on a particular cache or capacity device. Each object is an individual block storage device. Each component of the virtual machine is created as an underlying virtual machine object.
VMware vSAN is an object-based storage solution. With the appropriate storage policy selected, SPBM makes sure the virtual machine is allocated the resources needed and is provisioned on the correct tier of storage configured based on the performance and other characteristics. When a virtual machine is provisioned you can choose a VM storage policy to support the application that is running on a particular virtual machine. This is referred to as Storage Policy-based Management (SPBM). In addition to easily changing your storage configuration, VMware vSAN allows a powerful new way to control storage down to the VMDK level of a virtual machine. With VMware vSAN, this can all be achieved in the software-defined architecture of the vSAN storage model. In times past, this generally meant destroying the original LUN and reprovisioning a new LUN with new characteristics. VMware vSAN allows you to move beyond the traditional concept of storage LUNs that were extremely labor-intensive to change, grow, or reconfigure. This allows your environment to gain many benefits using VMware vSAN, including easily scaling up and scaling out as a mechanism that is built right into the vSAN solution and in essence, is now built into the vSphere solution in general as part of the hypervisor itself and vCenter Server. By using automation and storage pooling, this allows abstracting the hardware from the storage solution and easily pooling resources between servers.

VMware vSAN is VMware’s software-defined storage solution that allows automation and pooling of storage through a software control plan, and the ability to provide storage from industry-standard servers. As one of the foundational pillars of your SDDC, software-defined storage is at the heart of your data. The software-defined data center is the new mindset moving forward that allows your business to be as agile, automated, and abstracted from underlying hardware infrastructure as possible. VMware vSAN was a product of this new way of thinking with an official release of vSAN in 2014. VMware was a pioneer of the Software-Defined Data Center (SDDC) concept which it coined back in 2012 to virtualize all aspects of the data center including compute, network, and storage. Pros & Cons of running a VMware vSAN storage solution.
What are the licensing, host, storage, and networking requirements?.In this post, we will take a deeper look into VMware vSAN. The features and functionality with each new release of vSAN continue to raise the bar for competitors to the product. VMware vSAN is continuing to pick up many new customers with each new release. The dominant leader in the enterprise data center when it comes to software-defined storage is VMware vSAN. Software-defined storage offers great benefits for housing your production virtualized workloads. Most hardware and software companies are jumping on the bandwagon to offer software-defined storage solutions. One of the software-defined technologies that have gained tremendous momentum in the past couple of years is software-defined storage.
