What is Data Reduction?
The capability for a storage system to physically reduce the amount of data stored, through data manipulation processes which may include data de-duplication, data compression, and / or thin provisioning.
Addressing Data Sprawl Resulting in Storage Consumption
Data reduction technologies solve the problem of data sprawl, which results in an accelerated consumption of storage capacity. As capacity is consumed, companies need to buy more storage – more frequently, increasing expenses. Furthermore, as capacity grows, IT support teams are further challenged to deliver consistent levels of performance and availability to key business applications, while also managing the hardware resources.
A Resolution That Defers Future Purchases
Data Reduction technologies allow for more data to be stored – and managed – with existing resources. This results in fewer systems being needed to store data to meet existing needs, and allows for deferral of future purchases, since the existing capacity of installed systems is extended. Through compression, de-duplication, and thin provisioning, companies can focus on managing one copy of data, as it resides in its most efficient state.
The RIGHTSTOR WORKSHOP Makes Sense…
If you’re buying additional storage capacity at an accelerated rate, or your expenses for off-site backups are increasing, then you could benefit from a review of how your business can use data reduction technologies across primary, secondary, and archival storage, by going through our RIGHTSTOR process.
In the RIGHTSTOR WORKSHOP at Cima, our approach stimulates joint collaboration to create a blueprint which reflects your objectives and ideal infrastructure vision that will address your business needs. We will allow you to discover how to improve operational efficiency and reduce cost through exploring available alternatives, and create an action plan for you to seamlessly incorporate data reduction technologies into your infrastructure.
The Value of Data Reduction
Through data reduction processes, acquisitions for new capacity may be deferred into the future. Storage management teams are also more effective, since they manage only a single copy of data, residing in its most efficient state.
Increased performance is also a benefit of Data Reduction technologies, since storage systems (disks) are not cluttered with multiple copies of the same data. What’s more – as data is compressed, it requires less physical movement of the disk read/write head itself, improving write operations. With compressed data, more of it may be pre-fetched into memory, potentially increasing the performance for read operations.
Thin provisioning provides the benefit of allocating only the space that has actually had data written to it, as opposed to assigning excess capacity that may not be used for some amount of time.
For the IT Professional
The IT professional will be more productive with data reduction technologies in place within the infrastructure. Time spent on management of capacity and storage allocation will be greatly diminished, as the pace of storage capacity consumption will be reduced.
For the Company
Data reduction technologies offer the opportunity for significant cost savings and expense recovery for your business. As stated above, purchases for additional capacity will be deferred, and the lifecycle for existing resources can be extended.
Using data reduction in primary storage also introduces the possibility for improved performance for key business applications since more data can be resident in cache memory, and in the event data is write to the disk infrastructure, the write operation should be faster due to data compression.
From a secondary – or backup – storage environment, data reduction or de-duplication offers the ability for less data to be backed up, copied to tape, or stored off site. Because many disaster recovery and tape vaulting sites charge based on the capacity of data or the number of physical cartridges, costs for these expense items can be reduced.
Finally, for those sites with remote replication in place, data reduction technologies offer the ability to send only changed, compressed data – only I the data to be copied doesn’t already exist at the remote site.
