It is just not
enough these days to have storage virtualization for the sake of storage virtualization.
Pooling heterogeneous resources and migrating data from point A to point B while
the application is up and running is great, but businesses really need complete
solutions -- solutions that provision storage more efficiently as well as virtualize,
protect, migrate, dedupe, encrypt, replicate, recover and archive any data source
in real time via policy.
There is a definite
need for a simple, yet comprehensive, solution that enables a more efficient
IT infrastructure and leverages existing assets, policies and procedures, all
while reducing the overall costs. This requires building an optimized suite
of integrated data services on a common platform.
This holistic
approach is called the "optimized data services" (ODS) utility. An
ODS utility enables physical abstraction and flexible data movement by virtualizing
existing datasets, storage and servers between compute and storage elements.
Once virtualized, this allows the creation of policies that enforce specific
service levels for explicit or pooled datasets. Physical constraints, such as
volumes in the same array, or SAN versus non-SAN, or storage network-attached
devices or hosts, should not hinder the grouping of data elements for consistency
or recovery purposes.
The overall administrative
burden is reduced, providing an element of automation to the design through
the thin provisioning capabilities for enhancing storage utilization thast the
ODS solution enables. Additionally, capacity expansion for running applications
can occur in real time and on demand by the compute resources in question. Recovery
time objectives (RTO) and recovery point objectives (RPO) are achievable at
minimal costs based not on budget constraints, but by the service level agreement
(SLA) policy applied to the application. This unique capability can only be
achieved if the solution also automatically applies efficiency in data storage
and movement. Such effciency is accomplished through de-duplication and sub-block-level
monitoring of all stored data to ensure only unique data is stored and replicated.
