Insider Insights from the industry Back to the Future Virtualization brings new technology to mainframe tape By Ed Ahl W hile IBM researchers can now store data in 12 atoms, it still takes considerably more atoms to do so using tape. Today, tape remains a major expense and performance roadblock for enterprise data centers. However, it’s possible to bring advanced technologies to long-term storage through virtual tape backup. usage charges, space utilization, staffing charges and power consumption. On the benefit side, VTL can provide faster data recall, more reliable and realistic disaster recovery (DR), a smoother migration path to new storage technologies, and access from multiple servers— including Linux* partitions—to channel-attached backup. Virtual tape libraries (VTLs) harness the speed of disk-to-disk and the cost-effectiveness of diskto-tape. They also help consolidate and manage backup in increasingly heterogeneous data centers. VTL for the IBM System z* platform delivers superior ROI. On the cost side, it can reduce mainframe CPU cycle demands, CPU upgrades, 10 MAY/JUNE 2 012
