Tips on Consolidation, Dedupe, Data Reduction & Other Ways To Make The Most Of Your Storage - September 28, 2008
Orlando Florida -- With today’s challenging budgets, it’s becoming increasingly difficult to secure the dollars needed to procure new technologies. But some technologies are too essential for the enterprise, leaving little wiggle room for skimping on resources for these technologies. Also by working with a vendor that has a working knowlege of what it takes to consolidate, automate, protect and make sure you are in compliance with your data.
Take storage, for example: An increasing dependence on storage within the enterprise and its importance in meeting regulatory data storage and archival requirements mean that, even under the onslaught of budget challenges, enterprises cannot afford to take monetary shortcuts with their storage infrastructures, says Brian McCarthy President of Storage Reseller Sencilo Solutions in Lake Mary, Florida.
So, what’s Joe Administrator to do when management clamors for budget cuts even as requirements for maintaining storage infrastructures continue to increase? Well, one general solution is to leverage new storage technologies that allow administrators to get more out of their existing storage assets. And thankfully, there are a number of approaches that allow administrators to wring more returns out of their existing storage assets.
What, then, are the main challenges facing administrators today when it comes to storage? Most experts agree that one of the main challenges is the ongoing growth of data. Tom Grave, director of product management for Diligent Technologies (www.diligent.com), a wholly owned subsidiary of IBM, says handling rapid data growth; managing costs, backup, and recovery operations; and implementing offsite data protection are all challenges administrators are facing. In addition, he adds, recent trends in regulation and compliance are also playing a larger role. Resources are also an issue: According to Christophe Guittenit, founder and CTO of Seanodes (www.seanodes.com), today’s primary challenge for administrators is dealing with flat budgets as storage needs continue to increase.
Reclaim Unused Space
One way to get more out of existing storage assets is to ensure those assets are fully utilized. In terms of storage, the internal disks in application servers are usually unused, says Guittenit, who adds, “This requires the addition of new storage hardware frequently, both network dedicated to storage and disk arrays.” One way to do this is by using technologies that allow administrators to reclaim the large untapped storage capacity embedded in application servers to cover storage needs. Typically, this type of technology works by using software to convert internal disks and direct-attached storage into shared storage that can be used to store more data.
Andrew Mapp says this approach reclaims bought and unused storage capacity in application servers and turns them into a highly efficient, reliable, virtual networked storage device. In essence, this approach enables the use of heretofore untapped sources of storage in the enterprise: It’s all about making use of what’s already readily available within enterprise server internal disks and DAS.
The SME Challenge
One of the main challenges for SMEs is a lack of time and attention, due to the fact that SMEs lack the IT resources to scale up their business for maximum operational efficiency and better performance, says michael Eitenbichler. This, he adds, is necessary as the need to store more data becomes essential in order to stay competitive. So, even though most companies are now managing more than 30 times the amount of data they had less than 10 years ago, this means more data to manage and more complex technologies to learn.
“Ongoing administration and maintenance of the existing storage infrastructure can consume the lion’s share of most organizations’ IT budgets and time,” says Eitenbichler. And, he adds, with budgets remaining flat and data requirements increasing, the need for better storage resource management has become a business priority.
Eitenbichler points to five major methods administrators can use to reduce the costs of managing their existing storage assets and protecting their data: consolidation, centralized backup, deduplication, thin provisioning, and data life cycle management (see the “Managing & Protecting Data Cost-Effectively” sidebar for more information).
Saving Space
Quantum Corp.’ Grave says two technologies at the top of the list of approaches that help users do more with their existing storage infrastructures are deduplication and virtualization. Deduplication technologies find and eliminate redundant data within a storage repository, adds Grave, so the primary value proposition of deduplication is to maximize storage utilization.
In fact, says Carter George, vice president of products with Ocarina Networks (www.ocarinatech.com), data reduction techniques such as compression, deduplication, and more advanced storage optimization can allow an administrator to store as much as 10 times more data on the storage that they already have. For example, adds George, administrators can use caching and the use of memory for file-based storage, while solid-state disks are poised to emerge as the fastest drives in a storage system.
In terms of utilization, adds George, the keys are better utilization of free space and better utilization of the space needed for data. “The key technology for free space management is thin provisioning,” he adds. This technology, says George, virtualizes the view of disk space to users and allows free space to be allocated and managed more efficiently. He adds that storage optimization is the key technology for utilization of the space needed for data storage. By using this technology, users can shrink existing files by as much as 90%, thus enabling the storage of up to 10 times more data on disks already owned by the enterprise.
Improving Performance
Beyond utilization, all administrators also want to improve the performance of their storage infrastructures. Jon Affeld, senior director of product marketing at BlueArc (www.bluearc.com), points to a number of techniques that can be used to enhance performance, including striping, tiering, caching, and upgrading.
Striping data across LUN groups and disk arrays allows administrators to do more work in parallel and bring more resources to bear for specific tasks, adds Affeld. An example, he says, is a database striped across several hundred disk drives all acting as a logical unit.
Tiering means creating different tiers of disk media and storage arrays optimized to different tasks, he adds. The use of caching technology to preload commonly used data and files can deliver speedier access. Finally, he emphasizes, upgrading to the latest firmware or technology possible for existing equipment can also improve performance.
“Look for products that are modular, easily scalable, and allow upgrading with data in place and minimal disruption to service,” says Affeld.
At the end of the day, there are a number of technologies that can enable administrators to get more from what they already have in place. In a sense, the challenge for administrators has moved beyond figuring out which primary storage solutions to choose to determining what technologies are required to effectively manage and enhance the performance and utilization of what’s already in place.
Managing & Protecting Data Cost-Effectively
Brian McCarthy of Sencilo solutions (www.sencilo.com) points to a list of five methods SME customers should focus on to reduce the costs of managing and protecting data:
1. Consolidation. Moving data onto centralized storage systems can help administrators avoid the fragmented capacity that leads to extra maintenance work, low disk utilization, and huge backup headaches.
2. Centralized backup. SMEs should look at disk-to-disk-to-tape backup solutions that initially store data on disk drives and eventually migrate it to tape for long-term data retention. Ensuring successful backups on a nightly basis is “mission-critical,” says Eitenbichler.
3. Deduplication. Using de-duplication allows administrators to drastically reduce the amount of data stored on disk-based backup systems at data reduction ratios of 20:1 or even 40:1.
4. Thin provisioning. This technique eliminates wasted capacity by automatically sizing storage capacity needed by application requirements.
5. Data life cycle management. It sounds simple, but keeping an inventory of storage devices onsite, available capacity, and growth trends can allow administrators to delay additional purchases for several months.
