Simplifying Storage Management
As the amount of NAS storage under management has grown, enterprise IT groups
have been continually challenged by the complexity of managing a large number of
discrete file systems and by the on-going cycle of adds, moves and changes across
these systems. Further this basic storage administration typically requires user
downtime and manual client reconfigurations.
The NAS virtualization switches allow enterprises to dramatically simplify storage
management by enabling online storage administration. The file virtualization
technology separates the logical from the physical location of the data. This allows
IT managers to perform online storage administration, with out disrupting user
access to data. As a result, storage provisioning, capacity balancing and
decommissioning can be done online, during regular business hours. In addition,
because the mount points are now virtual mount points, no application
reconfiguration is required.
Transparent Data Migration:
For most IT organizations storage growth and the normal cycle of hardware and
software upgrades creates ongoing need to move data and consolidate storage
devices. However, data migration is typically a very painful process. Most
migrations require manual intervention, cause application downtime, and often
require cumbersome client reconfigurations.
NAS virtualization switches are able to move data with affecting user access.
Administrators can use powerful polices in these devices for a range of data
migration tasks such as moving data off legacy file servers to new NAS devices,
balancing storage capacity, or performing software upgrades. Most importantly the
data migration tasks can be automated and occur with out any user downtime or
client reconfigurations. The result is a rapid non-disruptive data migration that
significant reduces the pain and operational overhead associated with moving data.
Increasing Capacity Utilization:
In many IT environments it is difficult to add storage capacity to existing file systems
with out user disruption. This often results in storage capacity being over
provisioned to meet demand. As a result, enterprises have low NAS utilization rates
(30-50% average) and have no simple way of optimizing resource allocation.
NAS virtualization switches provide the ability to dynamically balance capacity
utilization across back end file systems. This is done transparently to clients and
applications. This allows storage managers to maximize storage utilization and
eliminate stranded capacity. In addition, the switches enable IT mangers to do thin
provisioning of storage, because additional capacity can be added with out downtime
or disruption to user access.
In an effort to reduce capital expenditure, many enterprises are seeking to move
non-critical business data off of expensive storage resources to lower cost
alternatives. Unfortunately, migrating data between systems and managing the data
lifecycle over time is a complex process with high operational overhead.
