If only you could have the problem of having a 2% investment in a company whose share price has gone to the moon, right? Well, that's where Cisco is with VMware. While its equity stake looks smart at this stage, in the longer term Cisco is going to have to make a bid for either EMC (VMWare's parent company) or figure out the next step to get in the virtualization game.

Here's the problem: Virtualization and cloud computing, VMware's bread-and-butter, is the technology flavor of the decade, and Cisco is relying heavily on a strategic partnership with VMware to get it done. Sources in Silicon Valley are chattering about what Cisco will do about virtualization, a party its been largely left out of. As VMWare's price has shot up while Cisco's share price has stagnated, it's now become all but unaffordable to for Cisco -- VMware now has a market capitalization of $33B.

Little storage player 3Par Data is suddenly the envy of many, as it gets caught up in a massive bidding war between Dell and HP which have caused its share price to nearly double in a period of a week.

What gives? Well, virtualization and data centers, in a nutshell. As traditional enterprise spending slows, data centers continue to grow like mad, fueled by Internet services, social networking, and "cloud computing." It turns out that storage and virtualization services -- 3Par blends both of these -- are crucial to this high-growth area of computing.
