After getting clocked yesterday thanks to downbeat guidance from the company itself and VMware, EMC (EMC +2.6%) is rebounding with the help of an upgrade to buy from Monness Crespi. The rally comes as EMC introduces a refresh for its Greenplum Data Computing Appliance, often used in big data projects. The update includes major performance gains, Isilon storage integration, and joint support for Greenplum's database and the Hadoop analytics framework. Also, EMC's RSA unit is rolling out new security analytics software.
