Hi Thanks for all the input. I did some more research on the high point and even though it talks about smartctl it doesn't actually get you through to each device.
I have now started to look at the adaptec 51245, 3 x sas connectors with fan outs to sata. and 1 x sas external connector. Seems like adaptec have done some work on linux and making more information more accessible to linux I always though of adaptec as being on the pricey side but this isn't too bad a price.
