VMware builds storage into vSphere kernel
Virtual SAN said to 'change the way storage is operated'
Cloud and virtualisation software company, VMware has announced its first software-defined storage product.
VMware Virtual SAN is built directly into the VMware vSphere kernel and provides a new level of hypervisor-converged storage.
According to VMware, the software abstracts and pools internal magnetic disks and flash devices from industry-standard x86 servers to produce a high-performance and resilient shared datastore for virtual machines (VMs). Internal benchmarks say that, VMware Virtual SAN performs 2m input/output operations per second (IOPS) on a read-only workload on a 32-node cluster; and 640,000 IOPS on a mixed workload on a 32-node cluster.
John Gilmartin, vice president and general manager of SDDC Suite Business Unit, VMware said: "Today VMware changes the way that storage has been operated to date. VMware Virtual SAN is a radically simple storage solution optimised for virtual environments that brings an application-centric approach to storage management. Customers that know VMware vSphere know VMware Virtual SAN, and can rely on that familiarity to hit the ground running with VMware Virtual SAN."
VMware Virtual SAN features Hypervisor-converged architecture that enables it to deliver the data path while consuming less than 10% of CPU resources; it also uses flash to deliver performance acceleration through read-write caching. According to VMware, the software allows customers to linearly scale their clusters on demand by adding nodes to a cluster, or disks to individual nodes. Its storage policy based management means that Virtual SAN can shift the management model for storage from the device to the application; a single VMware Virtual SAN datastore provides differentiated service levels based on individual VM policies. VMware claims that for administrators, there are no complex configurations through LUNs or volumes, they avoid overprovisioning, and can change policies easily. With automated provisioning and management, administrators improve the ability to meet service-level agreements (SLAs).
