Battery placement options
Maximizes controller throughput by allowing concurrent communications with all attached
SATA drives through a pool of 32 direct memory access (DMA) channels.
Achieves unmatched data protection while maximizing performance in critical RAID modes
when data availability, accessibility, and data protection are most needed.
Maximizes application performance under heavy loads by dynamically allocating controller
cache for maximum bandwidth
Dramatically increases subsystem reliability by radically reducing cable count and improves airflow
Two sets of parity are simultaneously calculated, written, and rotated across all the drives.
This allows the array to survive up to two drive failures without losing data, for significantly
improved fault tolerance.
Aggressively Caches write and read data and improves write and read content streaming.
Provides intelligent caching algorithms to improve application performance in real world cases.
Faster foreground initialization for RAID 5 and RAID 6 arrays with 16 or more drives.
Fastest background initialization for newly created arrays.
Faster rebuild completion. Shorter verify/initialization.
