Web(2) UltraRAM uses much less space on the chip (and in the bitstream, because it doesn't have initialization settings) than equivalently-sized block RAM. For each 288KB UltraRAM block, you might only get two 36KB BRAM blocks. Xilinx has provided a significant amount of both RAM types on the chip, so you can use whichever one is more suitable.
