E5600 Series Storage Systems With Dynamic Disk Pools
Facilities counting on a certain bandwidth to meet production deadlines can't afford to have their storage systems slow to a crawl for several days during a 6 terabyte disk rebuild. Now with NetApp E-Series, they don't have to. Broadcasters and production facilities have discovered that dynamic disk pools (DDP) on E-Series storage systems provide more consistent video bandwidth than other block storage systems for two reasons. One is that the resiliency scheme provides drastically more consistent performance upon disk failure (50 percent more bandwidth during rebuilds than standard RAID). The other is that it dramatically reduces data rebuild time (1/8 the time of standard RAID).
