In a constantly evolving business landscape, organizations rely on IT to help them stay competitive in their respective industries. To address growing business requirements, organizations need to take the first step in adopting a hyper-converged infrastructure to benefit from a cloud operational model to storage while utilizing their existing processes and tools. With HCI, your organization benefits from reduced storage costs, increased agility, and future-proofed infrastructure.
VMware vSAN is an HCI, software-defined enterprise storage solution that works on shared storage to maximize efficiency and reduce the total cost by virtualizing local physical storage systems. It works on user-defined rules and policies, through VM-centric policy-based management, for provisioning and managing storage and can be changed depending on the requirements. With these policies, simple tasks are automated while balancing storage resources to optimize HCI efficiency and reduce management time.
The VMware vSAN architecture is based on storage blocks. Since VMware vSAN uses an object-based storage system, each object constitutes a block of data within the VM (Virtual Machine). The primary management system is a vSphere cluster, which one can create as either a hybrid vSAN or all-flash cluster. The difference is that an all-flash vSAN relies on flash storage technology to manage cache and capacity tiers. At the same time, a hybrid vSAN uses a combination of flash and conventional spindles.
The integration of vSAN with vSphere helps to provide the highest levels of performance with reduced impact on CPU and memory. In addition, the distributed architecture of VMware vSAN helps in qualifying various rules of storage policies to be enforced despite any hardware or network failures.
Some important features of VMware vSAN include :
– Unified management through the native integration of vSAN with the VMware Cloud Foundation stack, eliminating the requirement for the training and operation of specialized storage interfaces.
– vSAN Health service to diagnose and troubleshoot cluster component complications.
– Software-based deduplication and compression to optimize all-flash storage capacity, yielding data reduction with next to no memory and CPU overhead. It also provides an option only to use compression to cater to environments where space efficiency must be at equilibrium with performance needs, decreasing the failure domain to an individual disk from a disk group.
– Erasure coding to ensure efficient storage management and security through increasing usable storage capacity whereas ensuring that data resiliency remains unchanged. It can tolerate one or two failures with single or double parity protection.
– Software-defined HCI data encryption with vSAN Encryption for data-at-rest and data-in-transit security at cluster level that supports all vSAN features.
– Easily provision a file share with a single workflow with integrated file services and use vSAN as a unified storage plane for block and file storage.
The VMware vSAN creates a single storage pool by collecting local or direct-attached storage devices distributed across all vSAN cluster hosts. With a single data store made available to provision, it won’t run out of storage space easily. vSAN can also automatically rebuild on other hosts or disks if the primary disk fails or is offline, which helps avoid data loss. You can also non-disruptively scale up your storage capacities by adding disks to existing hosts or scale-out by adding hosts to a cluster.
With VMware vSAN, your organization can benefit through the following ways:
– It reduces the total cost of ownership with advanced security to prevent loss and simplify management by deploying on industry-standard x86 servers.
– Ease of use due to the integration of vSAN with an organization’s existing vSphere, simplifying the installation and configuration process and making it less time-consuming.
– It can replicate data synchronously between two separate sites that could be extended across two geographies, providing local protection across stretched clusters. In case of an entire area or local component failure, it enables enterprise-level availability with zero downtime and no data loss.
– Quality of Service (QoS) controls, monitors, and limits the IOPs that are consumed by specific virtual machines.
VMware has different licensing options for vSAN: standard, advanced, and enterprise, depending on user requirements. In addition, each of the licensing options has vSphere replication and all-flash support.
