The Dell SC4020 storage array is based on Dell’s flagship SC8000 platform. Offering similar benefits at a smaller scale, the mid-tier SC4020 begins with a rock-solid enterprise hardware architecture. Dual redundant controllers, 24 internal drives, eight ports of 8Gb Fibre Channel network access, plus four IP ports for management and replication are all delivered in a space-saving 2U chassis, making the SC4020 a true all-in-one solution. For expansion beyond 24 drives, add Dell SC200 or SC220 enclosures for a total of 413TB raw capacity.
