Do hardware suppliers of SAN devices have similar sorts of support agreements int hat they will support the hardware in line with a support lifecycle? And would there typically be requirements of the users to keep that support valid, e.g. firmaware levels they must work towards. I am trying to identify dells support policy for EqualLogic PS6100 but to no avail. If such an agreement is common with storage manufacturers, do you have any options in terms of part coverage once the company themselves stop supporting it, and what type of agreement is that typically termed?
