TSM Vs HDFS

[pankaj.puranik]

Hi

Has anyone done a study on the advantages of using HDFS over TSM.
In what situations HDFS is better over TSM?
There are not many papers on the internet that talks about using HDFS with CMOD and what advantages does it pose over TSM with SAN/NAS storage.

Thanks
Pankaj.

The idea is that if you're already a cloud-based shop, and you already have HDFS up and running, you can use it for it's lower total cost of ownership.

If you don't have it already, it doesn't seem like anyone is going to build an HDFS system just for CMOD.  Others may have a different opinion.
