It depends ... if you actually have a use for the customisations, yes. If you just want the basics of who (what's in the enclousure), what (activity) and where (locate) then I think it solves your problem almost entirely. So, entirely as a straw horse, tell me what else your enclosures provide that I haven't listed in the four points. The SES standards too provide a huge range of things that no-one ever seems to implement (temperature, power, fan speeds etc). I think the users of enclosures fall int these categories 85% just want to know where their device actually is (i.e. that sdc is in enclosure slot 5) 50% like watching the activity lights 30% want to be able to have a visual locate function 20% want a visual failure indication (the other 80% rely on some OS notification instead) When you add up the overlapping needs, you get about 90% of people happy with the basics that the enclosure services provide. Could there be more ... sure; should there be more ... I don't think so ... that's what value add the user libraries can provide. James
