Iilori ye-chassis yombane yongeza umsebenzi wokusebenza kombane kwilori ye-chassis yezandla yokuqala. Ubungakanani bubonke buyafana nelori ye-chassis esemgangathweni yoqobo. Inika isiseko se-hardware esiyimfuneko ukuze sifezekise iimfuno zobuqili, ezicwangcisiweyo, ezikude zekhabhinethi yokutshintsha. Emva kweminyaka yokuphucula kunye nokusungula izinto ezintsha,ilori ye-chassis yombanes baphuhliswe ukusuka ku-1Stisizukulwana sonyuse uhlobo ukuya kolu 3 lwangokurd uhlobo oluhlanganisiweyo lwesizukulwana. Ukuqala ngo3rd Isizukulwana, iimoto ezincinci eziyilwe ngobuchwephesha ezisisigxina ze-DC ziye zamkelwa ukuba zisebenzise ngokupheleleyo indawo engaphezulu ye-chassis yokuqala. Emva kofakelo, akuyi kutshintsha ukuphakama, imilinganiselo yokufakela yangaphandle, umsebenzi odibeneyo, njl. yelori ye-chassis eqhutywe ngesandla, kunye nesakhiwo esilula kunye nokuguquguquka okunamandla.
