As businesses around the globe contend with the incessant, pounding waves of data crashing into their data centers, some may wonder how we reached this point in the first place. While there was a great deal of experimentation going on in the early days of the computer industry, and while there have been a great number of innovations since, it's fair to say that the digital storage industry as we know it today would not have occurred without an innovation created by a team of IBM engineers 60 years ago this May. The innovation enabled the massive calculating machines to save their results digitally
This paper highlights the importance of mirroring as a data protection strategy to minimize risk of data and system unavailability and the advantages of IBM® XIV® Storage System asynchronous mirroring. It covers the system’s essential mirroring solution characteristics and organizational mirroring requirements that ensure business continuity. While this paper touches on the value of synchronous mirroring in certain situations, its primary focus is asynchronous mirroring.
Reading this paper will give you a clear understanding of effective enterprise mirroring implementations and the IBM XIV Storage System series solution, which offers
When I talk about the various state-of-the-art capacity optimization solutions that are now appearing in the market, the same comment usually arises: “Isn’t this the same as zip?” Or a long-tenured storage pro will remind me that, “Stacker died out a long time ago, so why is this any different?”
These are good points: The difference between traditional compression and modern data deduplication is somewhat hazy. And it doesn’t help that various implementations fall all along the spectrum from “mildly interesting” to “cutting edge!”
Over 100 years ago, Samuel Morse defined a coding scheme for text messages. He optimized the efficiency
The Transaction Processing Performance Council still doesn't know how to do its own abbreviation after 24 years of existence, but it does know a thing or two about getting IT hardware and software vendors together and hammering out benchmark tests and pricing metrics to help server, storage, database, and middleware buyers try to figure out what they might want to buy and what kind of value they might expect from what they buy.
The TPC was founded in 1988 following an uproar in the server racket after IBM ran its own RAMP-C COBOL benchmark test on its AS/400 and System/38 minicomputers, pitting them against a bunch of Hewlett-Packard
