Sissejuhatus

Mellanox riistvara

Väited

  • Mellanox nö kangemad võrguseadmed jaotatakse kaheks suuremaks osakonnaks: 1. SmartNIC, 2. SuperNIC
  • SmartNIC - nvidia connectx seadmed
  • SuperNIC - nvidia bluefield seadmed

ConnectX seadmed

  • 'connectx-6 lx' ja 'connectx-6 dx' seadmed on kõik ethernet seadmed (st mitte infiniband)
  • 'connectx-6' seade on füüsiliselt universaalne ethernet/infiniband seade, st võimalik on tarkvaraliselt kaardi poole pöördudes lülitada ta käima ethernet või infiniband režiimis
