Kontroler RAID PERC 4e/Si do serwera DELL 1850.

Kontrolery nie posiadają baterii - można je dokupic na pozostałych moich aukcjach.

Kontrolery posiadają wgrany najnowszy firmware.
W zestawie jest płyta kontrolera, pamięć podtrzymująca 256MB oraz osłona plastikowa z kołkami mocującymi - czyli to, co widać na zdjęciach.
