The Sun Fire X4450 supports up to 24 cores on 4 sockets and up to 256 GB RAM (But our machine has only 32 GB). The 2RU case can home 8 SAS disk drives in maximum.
After we had put the machine in our 19" rack we saw that the X4450 can also be used as a really good beer warmer, because the serverroom is also our beer invetory. As a demonstration I upload this screen shot of our temperature monitoring.
