The Dell WH3W8 is an eight-port (2- x4 connectors) external 12Gbps SAS solution for performance-hungry external storage environments supporting up to 192 SAS hard-disk or solid-state drives.
As storage demands expand and processing loads grow, it becomes increasingly more difficult for administrators to achieve maximum performance and scale from their applications. The newest line of Dell EMC PERC cards, built on the LSI 3108 dual-core PowerPC RAID-On-Chip (ROC), offers unmatched I/O performance for database applications and streaming digital media environments.
The PowerEdge RAID Controller (PERC) H830, with eight external ports (2- x4 connectors), delivers two PowerPC processor cores and a 72-bit DDR3 interface that drives 2GB cache memory. This controller is ideal for configuring external storage enclosures with high-performance SAS hard drives and application-accelerating solid-state drives. The PERC H830 exploits the potential of 12Gbps SAS SSDs for unsurpassed performance and enterprise-class reliability.
