Keeping up with the latest data storage technologies, concepts, methods, products and platforms can be daunting. Boost your storage knowledge and career with these online courses
"Did you know that one of the earliest data storage devices was the humble punch card?"
writes Rahul Awati
"Invented in 1890 and used to program mechanical devices like textile looms, a punch card could hold only 80 characters. That is not even enough to fit a fleshed-out tweet. Compare that to today's digital universe estimated to hold 2.7 zettabytes of data. That's 27 followed by 17 zeroes.
All that data storage requires IT professionals who know what they are doing. Fortunately, there are a number of online courses available to help keep even the busiest storage admin up on the latest in data storage technology and best practices..."
When companies invest in a technology, they want to know that they will get a return on their investment for years to come
"FC has had an accurate roadmap for over a decade, showing the past, present and future of the FC physical layer. The interface has been progressing since 1996 by doubling the data rate (FC) every few years and the roadmap shows the progression will continue far into the future.
The ANSI INCITS T11.2 Task Group (T11.2), the standards body that defines FC speeds, finished 64Gb FC in 2018. 64GFC runs 9% faster than 50GbE and has been defined for a Bit Error Ratio (BER) of 1E-15 that is 1,000 v better than Ethernet that has a 1W-12 BER. 64GFC products are expected to ship in 2020/2021..."
IT admins who want the flexibility to provision IOPS independently from capacity can turn to certain software-defined storage and cloud services offerings
"Storage system design has always entailed a tradeoff between three parameters:"
opines Kurt Marko in SearchStorage
"capacity, throughput and IOPS. Unfortunately, for systems engineers, the physical limitations of storage components don't allow them to be set independently -- at least, not in hardware.
Parametric dependency forces designers to choose between capacity and performance. Need more throughput? Throw more spindles or SSD controllers at the problem and live with the unused capacity..."
