EMC has acquired privately held, venture-funded start-up nLayers, said EMC Chairman, President and Chief Executive Officer Joe Tucci at the company\u2019s analyst event in New York on Wednesday. InSight appliance, NLayers\u2019 flagship product, is designed to help users better understand and map relationships among applications, servers and devices. EMC is integrating the company\u2019s technology into its resource-management offerings, Tucci said. Financial terms of the deal were not disclosed.The acquisition is EMC\u2019s latest in a multiyear shopping spree, as it continues to try to expand from a storage hardware provider into a one-stop shop for storing, managing, accessing and securing data throughout the enterprise, for what EMC calls ILM (information lifecycle management). EMC has identified IBM as its main competitor in this area.Tucci also said Wednesday that he expects the company\u2019s resource-management business, along with four other business units, to grow into billion-dollar businesses in the next few years."We expect our core storage business will continue to sustain double-digit growth over the next several years, and we believe we will\u2014and it is our goal\u2014to grow five business areas to the billion-dollar level over the same several-year period," Tucci said.Those five businesses are resource management, content management, storage virtualization, information security and its virtualization software subsidiary, VMware.Tucci also hinted of hardware upgrades coming soon to the company\u2019s Clariion AX storage system line, at both the high and low end of the line, and of more lower-end appliance additions to its Celerra network-attached storage line. "We will continue to hit this appliance market hard, and the biggest thrust will be downmarket," Tucci said.On the software side, Tucci talked about a new tool coming in the second half of this year that will allow users to manage the company\u2019s data protection software through one central console. EMC will also offer similar capability for its archiving software, Tucci said.-Shelley Solheim, IDG News ServiceCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
