Finding your part number

HPE prints its part numbers in three forms: the option kit on quotes ends in -B21, with -H21 and -K21 variants; the spare part ends in -001; and the label on the module carries an assembly number ending in -091. Search by the number you have, or by the spec on the label (capacity, rank, speed). iLO (System Information, Memory) lists every installed module. If your number is not here, send it to us and we will match it, or browse by server model on the other HPE pages.
