6. Clustered storage will begin to move beyond pilot projects. Storage systems made up of large numbers of commodity Intel boxes with 4 to 8 drives (versus one storage controller with dozens or hundreds of drives) have promised high availability, quick rebuild times in case of node failure, and exceptional performance, but have mainly found a home in academic HPC systems. The promise of inexpensive, high performance storage will encourage more mainstream storage admins to look into this technology.
7. E-discovery and archiving will grow in importance as more legal cases depend on them. The potentially high costs of not being able to provide documentation of procedures being followed (or not) are being made clear by judgments against companies who ignored the need for an e-mail archiving and e-discovery system. That such systems can also enforce HR or legal policies on the use of e-mail and allow for self-service recovery of lost e-mails is just an added bonus.
8. Progress will be made in storage management, but an enterprise-wide, single-pane storage management system will continue to be a dream. SNIA (Storage Networking Industry Alliance) standards such as eXtensible Access Method (XAM) have lots of potential, but adoption will be slow. As per usual, the key vendors are all participating on the various committees, but reluctant to actually cooperate to the degree necessary to enable heterogeneous storage management.
9. The economy and green initiatives will drive power-saving systems. The cost savings gained by using SSDs will not be sufficient to drive adoption in enterprise systems in 2009, but we will see increased use of 2.5-inch high-efficiency drives, and vendors will add features like spin-down or sleep, especially in tier 2 or tier 3 near-line storage. Standards for evaluating actual energy savings will move the battle from marketing brochures to engineering initiatives.
10. There will be a battle between storage silos and SANs with better utilization. Often political boundaries within IT as well as practical, application-oriented limitations have prevented SANs from being efficiently utilized across multiple hardware and software platforms. Having a different SAN connected to each server defeats the purpose of SANs, but sharing storage among various admins with responsibilities for e-mail or databases or file servers on different operating systems can become really problematic. This is one area where the promise of SANs has not been fulfilled. Although some admins may give up and return to direct attached storage, others will be driven by the desire to utilize existing investments (especially when capital budgets are slashed) to find ways to get better utilization out of SAN systems.
