2U Profile, 12-bay Single-Controller 4Gbit/s
Fibre to SATA-II RAID Subsystem
Designed using Infortrend's next-generation, custom ASIC266 as a
dedicated XOR engine, the EonStor A12F offers unmatched performance
and ample margins for flexible load-balancing and multi-pathing
algorithms. Providing a twofold performance increase, the dedicated ASIC
architecture frees the PowerPC 600MHz CPU of XOR computing load and
features extreme versatility for the subsystem's various data protection
features with minimum disturbance to host access.
