Accurate data is critical to today's businesses. Managing its storage and retrieval is therefore decisive as well.
"Storage management" has come to be an umbrella term that encompasses not just data storage and retrieval, but such formerly independent topics as high availability (HA), disaster recovery (DR), and capacity planning. Add to that the realities of virtualization, cloud services, and multiplatform environments, and the whole topic of storage management becomes complicated and full of options that each enterprise must explore to find the right combination for their line of business.
Digging for Gold on Your Hard Drives
Driving it all, of course, is the value of data, an asset that seems to increase in both value and volume with each passing month as more and more ways are devised to parse, slice, and dice it to glean future strategies.
"Five years ago, it was unusual to see an IBM i customer with several terabytes of data—now it is the norm. This storage growth is driven by data analytics that today expands business-based decisions to an unimaginable scale and also I think by the low cost of storage media," notes Allan Campbell, CEO of Maxava. "These days, companies tend to keep everything, when previously they were typically very disciplined about purging old and unnecessary records and avoiding multiple copies of the same data. In fact, these days some systems look like a hoarder's garage!" he muses wryly.
"Organizations are seeing their storage requirements rapidly expand while their business becomes more and more reliant on constant access to mission-critical data," agrees Alan Arnold, executive vice president and chief technology officer at Vision Solutions. "This reliance is reflected in increasingly aggressive service level agreements and regulatory requirements related to downtime and data loss."
Supporting Data Value via Storage Strategies
The question for IBM i users becomes one of deciding how best to simplify their storage-management challenges while optimizing access to data.
"Whether it's for analytics, for building a data mart, for reporting, for a data warehouse project, for high availability, or for disaster recovery, companies should deploy off-the-shelf products that make this data movement possible and affordable," advises Giacomo Lorenzin, managing director of HiT Software. "And of course, anybody requiring to move, replicate, or update data between heterogeneous database systems (regardless of purpose) needs to be aware of the cost of time-to-implementation, ease of use, and ability to make updates in real-time," he adds.
"My best advice to those looking to simplify their storage management challenges is to start by taking a thorough, honest look at the true recovery time and recovery point objectives that are required for your business," offers Vision Solutions' Arnold. "Then seek out a vendor whose solutions address capacity planning, disaster recovery, and high availability with proven technology that will scale as your environment grows. Also look for that vendor to provide a migration solution that will allow you to reorganize and modernize your storage infrastructure as needed. Planning for the worst-case scenario and looking for a partner that can address your HA/DR, migration, and capacity planning needs are the best steps your business can take to survive an unexpected outage."
"In terms of advice to IBM i customers, I would say, start with the business," Maxava's
Unique Challenges in Storage for the IBM i
Clearly, much of this advice would apply to enterprises using any computing platform. Are there any particular pitfalls to which IBM i users should pay special attention?
"Traditional IBM i professionals have been slow to embrace the power of change," observes Richard Dolewski, chief business continuity officer at Maxava. "With the tools made available in the POWER framework and economies in delivering a virtual vs. physical storage management, the direction is clear. This is the new standard. Storage management is built into the operating environment and tightly integrated. The management is intuitive but should no longer be exclusively protected by a tape backup strategy."
"The IBM i platform is unique in many respects, and the skill sets necessary to manage it are unique," remarks Vision Solutions'
