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.

…The Mainframe Comes Back With a Vengeance

I’m at IBM Edge this week and in an IBM z Systems presentation. This is a bit of a “Back To The Future” segment for me because z Systems is the latest implementation of the IBM Mainframe which I first learned to program on. If we went back to 1984 when I entered the tech market, that decade the common belief was that the mainframe was dead as an architecture. But at the heart of the mainframe was the idea that computational power was more efficient if centralized, and that a system optimized on I/O could better handle a massive number of clients than individual remote systems. While initially individual servers better segmented workloads; thanks to virtualization and the idea of “the cloud” once again the concept of the mainframe is trendy, albeit as a sort of super-server at scale. But, recently, blockchain has turned the mainframe from being competitive to becoming cutting edge—and rather than chasing industry standard servers, suddenly it is leading them. Let’s talk IBM z Systems this week. To read the complete article, CLICK HERE NOTE: This column was originally published in the Pund-IT...
