Unlike the conventional NAS systems that preceded them, scale-out NAS not only can handle unstructured data storage , but it can simplify storage management, boost capacity and improve performance. With scale-out NAS, new hardware can be added and configured on an as-needed basis. When the storage limit is reached, simply add another array to the system to expand capacity. Storage can be accessed and controlled across different arrays, keeping management simple as hardware is added. However, scale-out NAS may not be the best fit for enterprises with large numbers of small files.
The original proposal also dictated that the legislation would in theory "apply for all non-. companies without any establishment in the ., provided that the processing of data is directed at . residents," one of the biggest changes with the new legislation.  This proposed change carried on through to the legislation's final approval on 14 April 2016, potentially affecting entities around the world. "The Regulation applies to processing outside the EU that relates to the offering of goods or services to data subjects (individuals) in the EU or the monitoring of their behavior," according to W.

Additional changes include stricter conditions for consent, broader definition of sensitive data, new provisions on protecting children's privacy, and the inclusion of "rights to be forgotten." 
The acronym ALCOA has been around since the 1990’s, is used by regulated industries as a framework for ensuring data integrity, and is key to Good Documentation Practice (GDP). ALCOA relates to data, whether paper or electronic, and is defined by US FDA guidance as Attributable, Legible, Contemporaneous, Original and Accurate. These simple principles should be part of your data life cycle, GDP and data integrity initiatives. Data integrity and access control issues featured heavily within the warning letters issued by the FDA in 2015 so here is a timely refresh on the fundamentals.
