which sends user requests for information to the data repository independent of its physical location—such as spinning disk or tape—and delivers that data to the user regardless of the operating system platform from which the request was generated. Storage virtualization can be accomplished with file-based systems, such as network attached storage (NAS), via a distributed file system across a redundant array of independent nodes. It also can be used for in-box systems such a storage area network (SAN) by virtualizing heterogeneous disks behind the system. “Virtualization provides better performance, scalability and redundancy,” he says. According to Koller, the benefits of virtualization in healthcare are lower costs and faster response to change. In addition, it allows non-disruptive upgrades and migrations as well as faster recovery from unplanned events. Citing a Gartner Group study, Koller notes that by 2010, virtu- alization will be the most important technology in IT. A new storage virtualization technology enjoying some currency outside the healthcare archive environment is multi-system capacity recovery. This schema aggregates and recovers unused disk space across application servers and in some cases other systems into a network storage grid. Koller notes that multi-system capacity recovery’s performance with diagnostic image archives is unknown. The critical elements in deploying a virtual storage system are standards and standardization. “When you start dealing with proprietary anything it starts closing your options,” Koller noted. “You need to have a management environment that understands virtualization so that you can take advantage of automation. That allows you to be more responsive to your user community and minimize the downtime. The last, most critical piece is that you need to get buy-in (for virtualization) from your See MDR Publisher at SIIM booth #535 DICOM DISK PUBLISHING UNDER $15,000 Automated, unattended operation Completely self-contained system Dual CDR/DVD burners Integrated full-color label graphics Burns images with DICOM viewer to disk or USB memory DICOM Image management Most affordable DICOM disk publishing system DICOM DISK BURNING AND LABELING FOR EVERYONE WWW.NAITECHPRODUCTS.COM MAKING THE CONNECTION HealthImaging.com May 2008 | Health Imaging & IT 5 http://WWW.NAITECHPRODUCTS.COM http://WWW.NAITECHPRODUCTS.COM http://HealthImaging.com
