[Beowulf] Large amounts of data to store and process

Hi Tony,

Sadly I cant go into much detail due to me being under an NDA. At this point with the prototype we have around 250gb of sample data but again this data is dependent on the type of air craft. Larger aircraft and longer flights will generate a lot more data as they have  more sensors and will log more data than the sample data that I have. The sample data is 250gb for 35 aircraft of the same type.

Good morning,

Around here, we're using HBase for similar purposes. We have a bunch of smaller nodes storing the data and all the management nodes(ambari, HDFS namenodes etc.) are vm's.

Our nodes are configured so that we have a maximum of 2 cores per disk spindle and 4G of memory for each core. This seems to do the trick and is pretty responsive.

But to be able to provide better advice, you will probably need to go into a bit more detail about what types of data you will be storing and which kind of calculations you want to perform.
