AMCC SIDECAR 3 - Manual (Page 12)

3ware features and benefits
StorSwitch ™
Non-blocking switch fabric architecture
Maximizes controller throughput by allowing concurrent communications with all attached
SATA drives through a pool of 32 direct memory access (DMA) channels.
Performance
StorSave
Powerful reliability enhancements Achieves unmatched data protection while maximizing performance in critical RAID modes
when data availability, accessibility, and data protection are most needed.
Data Protection
StreamFusion
Intelligent cache algorithm Maximizes application performance under heavy loads by dynamically allocating controller
cache for maximum bandwidth
Performance
Multi-lane ™
Award-winning connector system
Dramatically increases subsystem reliability by radically reducing cable count and improves
airflow
Reliability & Convenience
RAID 6
(On select 3ware 9650SE controllers) 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.
Data Protection
On-board PowerPC processor and G133
RAID engine (True Hardware RAID) Frees the host CPU to maintain overall system and application performance by managing all
RAID IO processing requirements
Performance
3Gb/s transfer speed
3ware Sidecar and SATA II controllers Doubles available drive-side bandwidth to exploit scalability features
Performance
Native Command Queuing (NCQ)
3ware Sidecar and SATA II controllers Improves performance of queued workloads by minimizing mechanical positioning latencies
on the drive. 32 outstanding commands can be reordered before reading or writing the data.
