Data gravity can attract increasing amounts of data, and brings with it onerous management overheads. We look at how to mitigate data gravity in datacentre and cloud
When it comes to enterprise applications, access to data - and lots of it - is usually a good thing. And the greater the volume of required data held locally to where it is processed, the better for the business, its applications, decision-making and, in some cases, compliance.
But the need to store and manage data brings its own problems too, including higher costs, lower system performance, and management overheads. Here we are dealing with the idea of data gravity.
There is growing evidence that data-rich systems attract more data. This, in turn, attracts even more data-dependent applications, which then bring in yet more.
20TB hard disk drives are soon going to be forgotten because 30TB models are on their way
Top HDD manufacturers including Seagate and Western Digital are on track to roll out their own line ups of 30TB hard drives by 2024. Capacity increase has been an ask among hard drive users for several years now and a handful of companies have been working on it a while now. Recently, Toshiba, Seagate and WD together with their partners made announcements about their roadmaps to build 30TB HDDs.
