Your LEDs will each drop about 2.75 volts with 100 milliamperes through them, and your driver's output current is adjustable from a low of 700 milliamperes to a high of 1.4 amperes with a compliance of 180 volts, so that means - ignoring the current for the moment - that the maximum number of LEDs you can connect in series is 180V / 2.75V ~ 65 LEDs.
If you drop that number to 50 series connected LEDs per string and connect 10 strings in parallel, then each string will drop about 138 volts with 100 milliamperes through it, the 10 strings in parallel will draw 1 ampere total from the driver, and the driver will adjust its output to 138 volts automatically.
LEDs exhibit a negative temperature coefficient of resistance, so as they heat up their forward voltage will drop and their forward current will increase, which will cause them to heat up even more, and more, and go into thermal runaway.
This becomes a problem when driving LEDs in parallel from a voltage source, and in your case probably won't become a problem since you'll be driving the array with a constant current source and the large number of LEDs per string will - more or less - cause the currents in all the branches to track.
Still, it seldom hurts to be prudent, and I'd add about 200 ohms of CYA ballast to each of the series strings.
