Question:
What is Dynamic Disk Pool or short DDP?
Answer:
NetApp SANtricity Dynamic Disk Pools (DDP) technology represents a significant advancement in storage system, data protection and data management. As disk capacities continue to grow without sufficient increases in data transfer rates, traditional RAID rebuild times are getting longer, even up to several days. This slow rebuild results in much more time with degraded performance and exposure to additional disk failures.
With five issued patents, DDP technology is designed to deliver worry-free storage through effortless management and self-optimization while maintaining predictable performance under any condition including recovery from drive failures. With up to four times faster rebuild, DDP technology significantly reduces exposure to multiple cascading disk failures, providing excellent data protection.
Key Features
Consistent Performance
DDP is designed to deliver and maintain high performance under all conditions—including while recovering from a drive failure.
Improved Data Protection
With up to eight times shorter rebuild times, DDP significantly reduces exposure to multiple cascading disk failures for excellent data protection.
Extreme Versatility
Flexible disk pool sizing optimizes system utilization and enables E-Series storage to be the “right size” for any environment.
