Hewlett-Packard has offered to buy 3PAR, a vendor of virtualized storage systems, for US$1.6 billion in cash, topping a bid of $1.15 billion made by Dell last Monday.
HP made its offer in a letter to 3PAR President and CEO David Scott on Monday morning.
The offer will force 3PAR's board to reconsider its merger agreement with Dell as the HP offer is a "superior proposal," HP's Executive Vice President and Chief Strategy and Technology Officer, Shane Robison, wrote in the letter.
Robison said that HP would be a better fit for 3PAR than would Dell, as both are Silicon Valley companies.
