HPE Smart Array P840/4GB FBWC 12Gb 2-ports Int SAS kontroleris. Patikrintas, pilnai veikiantis. Naudingas daiktas norintiems naudoti pigius SAS diskus HPE Gen9 ir Gen10 modeliuose, kuriuose standartiškai motininėje plokštėje yra tik SATA integruotas kontroleris.

HPE SmartCache funkcija jau yra aktyvuota, todėl nereikia papildomai pirkti lizencijos šios funkcijos aktyvavimui, kaip brangesniuose kontroleriuose, pvz., P408i-a SR, turinčiame net 2x mažiau cache atminties.

Papildomai yra:

Kabelis, skirtas sujungti kontrolerį ir backplane plokštę - 30 € (perkant kartu su kontroleriu - 20 €)
Akumuliatorius cache atminčiai palaikyti - 40 € (perkant kartu su kontroleriu - 30 €)
