NetApp (NTAP +4.2%) has gradually moved higher after Reuters reported Cisco (NASDAQ:CSCO) has discussed buying a storage rival to current JV partner EMC. Interestingly, EMC (EMC +2.5%), is also catching a bid today. NetApp's low valuation and enterprise storage clout have often made it the subject of M&A speculation, but the company's $12.8B market cap and likely demand for a decent premium would make it tough even for Cisco to digest the company.
