IBM Introduces Transparent Cloud Tiering for DS8880…

Archiving data from mainframe storage systems has been traditionally limited to an on premises physical or virtual tape tier. However, IBM has overcome that limitation with the introduction of Transparent Cloud Tiering (TCT) software that runs on DS8880 storage systems for z Systems. TCT widens the archiving storage targets to cloud environments and that brings the benefits of hybrid cloud with it, such as creating more and better options for managing both capital and operating expenses. Why IBM is doing this reflects the fact that data tends to change in value over time. Keeping older data on primary production storage is expensive not only in terms of storage costs, but also in terms of the resources needed to manage that data (such as for backup and disaster recovery). The solution is to archive less frequently used data to a different (and less expensive tier) of storage, but also making sure that the information can be easily recalled upon request. In the mainframe world, archiving is optimized only for the use of tape. That means an on premises solution, which while useful, lacks some of the benefits of a hybrid cloud solution that IBM TCT supports. Let’s consider that more closely.

Even if Disk Were Free You’d Still Want Tape

The cost of disk capacity has come down dramatically over the last two decades and, thanks to technologies like scale-out NAS and object storage, the ability to manage petabytes of data is certainly a possibility. But the cost to power and cool this storage plus the cost of data center floor space have increased dramatically. The net impact is that even if storage vendors gave disk capacity away, the cost to maintain that capacity could bankrupt you.
