Celestica Seastone2 DX031 Trident3-X7

Celestica is a Canadian OEM or ODM. As noted in the datasheet, the switch comes with an ONIE loader and that pegs it as a disaggregated product. Celestica, however, does not disclose its ASIC supplier in the datasheet. That this is a Trident3 comes from the SONiC hardware compatibility list.
