Overcoming The Challenges To All-Flash Arrays [29066]
Storage-Switzerland December 20, 2012
"All-Flash arrays are storage systems that are 100% solid state and provide a complete set of robust features like snapshots and replication, similar to traditional hard-drive based storage systems. While their performance enhancing potential is very appealing, All-Flash arrays have two basic challenges to overcome. First is the cost; an array populated entirely with (flash) storage capacity is about 10X the price of a comparable hard disk device. The second challenge is what to do with data that really shouldn't be on an All-Flash array because it can't take advantage of the performance that an All-Flash system can deliver..."

TDWI December 11, 2012
"According to TDWI's 2011 Next Generation Data Integration survey, the types of data integration functionality that are seeing the hottest adoption and growth today are those forms that involve real-time operation. This includes DI functions that inherently run in real time, such as replication, federation, and event processing. However, ETL and variations of it are also adapting to real-time requirements by executing intraday batches to augment the usual overnight batch processing, plus integrating with message and service buses.
Organizations embracing real-time data integration (RT DI) functionality should develop policies for why and how theyll use RT DI. The following list of rules can guide the adoption of RT DI..."
