====== System health monitoring ====== ====== System health monitoring ======
Most modern pc's provide fan speed monitoring and can shutdown automatically in case of any failure. The Newisys NA-1400 doesn't provide this mechanism. If the system fan of the NA-1400 fails this could lead to damage to the harddisks eventually causing loss of data. Generally speaking, Newisys would have made a good choice if they'd incorporated a proper fan failure protection scheme.  It is a simple mechanism and wouldn't have added much to the cost.

The onboard Philips USB chip has four ports available, but only two are currently in use. Two USB ports on the back could easilly be added with only minimal additional costs.

 +====== CVM: the resource hungry blob ======
 +CVM, which is some king of Java Virtual Machine, is used to provide the userinterface. While this interface look quite good, has a lot of features it is also slow and resource hungry. When a users requests a simple page like the CPU usage, the CVM process huggs the CPU for several seconds between 50% to 90%. It also eats up lots of memory: 7%. CVM also causes much of the constant harddisks activity I noticed when the system should be totally inactive (When I killed the process the NA-1400 .

 +Because much less powerfull embedded systems (e.g. routers) also have good looking webinterfaces and lots of features, it is certainly possible to provide the NA-1400 with a more elegant solution.
