Emulex (ELX) is acquiring Endace, a New Zealand-based maker of high-speed network performance management (NPM) hardware, for $130M in cash. The purchase allows Emulex, whose core storage adapter card/switch business is sputtering, to expand into a sizable growth market. But there's plenty of competition, not least from Riverbed (RVBD), which offers its Cascade NPM hardware line and is about to buy NPM software leader Opnet (OPNT). Emulex expects the deal to be neutral to FY13 EPS and accretive starting in early FY14. CC starting (webcast).
