In today’s data centers, conventional storage systems are
overwhelmed as a result of huge data volumes and complex solutions. With a new
approach to storage, VMware Virtual SAN is a new software-defined storage tier
for VMware vSphere that clusters server-side disks and flash to create simple,
high performance, flash-optimized shared storage that is designed for virtual
machines.
As hypervisor-converged storage software, Virtual SAN is
embedded in the vSphere kernel, which allows optimal data placement and I/O
optimizations. With this unique characteristic, Virtual SAN makes integration
with vSphere seamless and provides the highest levels of performance,
scalability and resilience. With the flexibility to build customized storage
systems in heterogeneous hardware environments, Virtual SAN can be deployed on
hardware from any server manufacturer.
Storage management is made simple because Virtual SAN is
integrated with the vSphere Web Client. This integration allows for simple
management of both storage and compute through a single interface. At the core
of VMware Virtual SAN is policy-based provisioning. Policies are created and
assigned to a VM and Virtual SAN handles the rest. As workloads shift, policy
adjustments are made simple and allow users to make the policies while Virtual
SAN adjusts them without interrupting service. When there is a need to expand
capacity or performance, hosts can be added to a cluster or disks can be added
to a host. VMware Virtual SAN also has no LUNs or RAID configurations while
removing the need for manual adjustments by automating time-consuming tasks.
VMware Virtual SAN works seamlessly with the entire VMware
stack and leverages VMware snapshots, VM clones, VMware vSphere Data
Protection, and vSphere Replication for data protection, backup, rapid cloning,
and disaster recovery. With built-in fault tolerance, Virtual SAN supports a
failures-to-tolerate setting on a per-VM or per-policy basis allowing for
granular protection of important data by distributed copies across vSphere
hosts.
There are many benefits of VMware Virtual SAN including the
fact that it is the first policy-driven storage product that simplifies how
storage in managed. High performance is achieved through the use of server-side
flash technology which enables true server-side read/write caching.
With the use of enterprise-grade HDDs and SSDs to create a
converged and resilient SAN-like storage tier within the hypervisor, Virtual
SAN lowers the Total Cost of Operation (TCO) by up to 50 percent over virtual
storage appliances and mid-range hybrid arrays. Virtual SAN also allows users
to make a low upfront investment and grow the aspects of storage that their
environment requires over time.
