Brocade Communications Systems, Inc. (BRCD) stock increased 3.45 percent to $6.90 in the after-market trading. Canaccord Genuity said in a research note that now is the time for Dell (DELL) to make a push into networking in a more concerted fashion, and that Brocade could be a target. Brocade has 70 percent of the fibre channel storage networking market, which has a high return on investment and should be a cash cow for the next five years. The other likely candidate, Juniper Networks (JNPR), gets most of its revenue from carriers, not enterprise, and is therefore not as good a fit, the brokerage said in a note to clients.

ServiceSource International, In (SREV) stock rose 3.20 percent to $19.69 in the after-market trading.
