Is entry level database server. It is limited to max 4 cpu cores or 200 PVU and 4 GB RAM. Capacity sub licensing is allowed, you can split server by virtualization technology and install multiple copies of DB2 Express on it.
DB2 can be licensed per server, PVU or FTL. Licensing per PVU is oldest licensing type, every CPU core has some PVU value assigned. Most Intel processors have 50 PVU units per core. Just compute cores you want to use with DB2 and multiply them by PVU value per core.
FTL licensing is very simple. You are paying same license fees every year, its something like renting software. Big plus is low upfront costs.
Newest licensing type is per server license. Advatage over PVU is that you dont have to care about type of processor used. Some newer Nehalems cores are 70, 100, 120 PVU units instead of 50 PVU for older Intel cores.

Annual software maintenance fees used in calculations were 20%. I am not quite sure if this is correct number. Prices for HA configurations are for both HADR computers main and warm standby. For more information about licencing DB2 9.7 in HA environments see this article.
