Webinar Topic: Understanding z/OS Disk Metadata - Catalogs, VTOCs, VVDSs, Indexes, and More
On October 26, 2021, DTS CTO Steve Pryor examined how data is stored on z/OS disks, or DASD (Direct Access Storage Devices) and the differences in non-z/OS systems. Your company's most frequently used, most valuable data resides on these devices, so an understanding of just how z/OS datasets are created, located, accessed, and deleted is as important to end-users as it is to storage administrators and system programmers.
Pryor also discussed how the concepts and structures invented in the 1960s have evolved into today's high-availability, high-performance, high-reliability disk storage subsystems.
