It was quite unfortunate that I lost data while using this blade server. There were a lot of factors, but I believe it should not have happened. I base this from the fact that we haven't lost any data from our HP C3000 enclosure and BL460 blade servers. One of the main things that I believe led to the data loss was the poor eco-system of vendors and knowledgeable solution providers for IBM in our part of the country. The vendor that sold us was just box-pushing the product without adequate knowledge in providing a solution that should not loose any data. I say this because we have another blade system from Cisco and it just works. We have a very knowledgeable system integrator and they provide excellent support. I just wish IBM here would also do the same.Overall, the product has great value for money. Under the right circumstances, I would definitely recommend this product. You should select a vendor that is knowledgeable about the solution and offer all the necessary components to protect the disk storage system from catastrophic data loss.
