RE: R710 error while booting: pcie training error integrated RAID
It worked using the H700 but find it odd that it doesn't work with the H710p? I thought a firmware update allowed any card to be used instead of the defaults that it shipped with officially?
Not necessarily, and ONLY if the release notes indicate such support is added. The H710 is not an upgrade option/model to the H700 - it is the model of controller supported in 12G servers, and the H700 is for 11G servers. It may work in an R710, but it was not intended to.
