Predicting Storage Growth for 2004 and Beyond, Part 2
Thursday May 27th 2004 by Leslie Wood
With the volume of data soaring and new regulations requiring that it be kept safe and secure, storage users will have to navigate a rapidly changing landscape in coming years.
The amount of new storage capacity installed each year is growing almost 80% annually, according to IDC. And companies across the globe are on the lookout for technologies to help them manage and store the ever-increasing amounts of information flowing in and out of their networks.
Email Archiving, Virtualization Are Hot-Button Issues
Another issue is whether email archiving products will come to dominate the overall archiving market. Lallier says email is the largest archiving issue
for data centers because of its explosive growth. "Everyone in the organization uses it, as opposed to databases, and the storage needs are constantly growing," he says. "With the compliance regulations now required in various industries, archiving and controlling this data will become an even more critical requirement."
However, Lauffin says that while the Sarbanes-Oxley Act of 2002 has caused quite a stir, financial data and other information such as film and historical archives are equally important. "One of the areas that I do not see people in the industry talking about is that there is a whole lot of data that customers actually want to keep that is on tape, and the educated end users know that they have a finite amount of time to get that data off of tape and onto something offering more permanence and reliability," he says.
"I am working with many companies on migrating data from older technology to systems that offer much greater reliability," Lauffin continues, "and in overall dollars I believe that there is as much new revenue to be generated from these types of projects as from new projects like email archiving."
Storage virtualization is another issue, with some saying it will be some time before the technology improves storage utilization. Lallier says storage virtualization alone cannot improve storage utilization, since it is a tool, not a solution. "It has to be used as part of an overall plan to reorganize the different data sets that an organization collects and maintains," he says. "In this, it is no different from archiving tools."
Sante, on the other hand, sees value in virtualization, adding that block-level virtualization within a SAN is a requirement. "For example," he says, "I have a SAN with a single $100,000 storage system with 10TB of capacity. I have 20 servers on the SAN and each server needs different GBs of capacity ... How can I even have a SAN like this without storage virtualization?"
Lauffin says virtualization only improves the way that companies work with data — it does not decrease the amount of storage space. "Virtualization makes moving data and adding more storage very easy for end users, but most end users of the caliber that would purchase a virtualization package developed their own approach years ago to maximize their storage efficiency," he says. "So a quality of life improvement is virtualization's greatest feature."
Some analysts predict that by 2006, storage area network (SAN) management functions will be embedded as part of storage element managers and storage resource management tools.
Sante says he sees this happening because such functions belong off servers and clients attached to the SAN and should migrate to the storage solutions. "I can talk for days about this, because users want to simplify their application servers and use them for the applications, and they want their storage infrastructure to provide access security, archiving, high availability, backup and recovery, and so on," he says.
Lauffin says he agrees because many of today's applications are not really applications, but utilities. "Years ago, programs like scan disk and defrag programs were sold as mainstream applications, but today these applications are simple embedded utilities," he explains.
Lauffin adds that there are many SAN management applications that fit into the same category. In addition, he says applications that are based on virtualization, online capacity expansion, and the like will also become embedded utilities. Lauffin says the type of applications or programs that will remain as apps will be databases, accounting, CRM, and similar functions, but he expects backup to become an embedded utility.
"Look at the caliber of features in the latest Microsoft operating system, and Oracle just implemented a backup feature for their database as long as you're going to disk," Lauffin continues. "It's not fully here today, but the writing is clearly on the wall."
With no end in sight to the exponential growth of enterprise data, it seems that the only way to control the cost is for companies to manage the data while ensuring its protection. While the storage industry has begun to address these issues, the future of enterprise storage management will continue to rely on a combination of the intelligence of storage technologies, the ability of storage vendors to create user-friendly products, and a storage management commitment from enterprises.
