Status: Legacy / discontinued
A 3U enterprise NAS with 16 SAS bays and two active-active controllers - both run at once, so if one fails the other keeps serving data. Each controller has a 6-core Intel Xeon, 32 GB of RAM and dual 10GbE ports, and NVRAM write cache with battery backup protects data during a power loss. Redundant hot-swap power supplies round it out.
