We can call it a worry free product Since we purchased our cluster pair with dell Hardware we had nearly no problems with the setup and production, even the perfomance/price ratio is hard to beat for the competitors. If you have any questions or problems the support jumps in very quickly, the response time is amazing and until now they had always an answer in the first place - no "support escalating to our technical super experts" stuff...i think you ask always people they know what they are talking about. The web config is easy to handle and of course the "step by step" guides are very detailed but not bloated.
