Product Description
The Dell 0TW399 is a PERC (PowerEdge Expandable RAID Controller) card that provides robust storage management capabilities for Dell PowerEdge servers. Featuring a PCI Express x8 interface, it delivers high bandwidth for data transfer, essential for performance-intensive storage applications. The controller supports 3Gb/s SAS (Serial Attached SCSI) drives, offering a reliable and fast connection for enterprise-grade storage devices. This hardware RAID controller offloads RAID processing from the server's CPU, ensuring consistent performance and freeing up system resources. It supports key RAID levels such as RAID 0 for performance striping, RAID 1 for data mirroring, and RAID 10 for a combination of striping and mirroring. These configurations provide options for enhancing data read/write speeds and ensuring data redundancy against drive failures. With 256MB of onboard cache memory, the 0TW399 accelerates write operations by buffering data before it is committed to the disk array. This significantly improves the perceived performance of storage-intensive applications. The dual-channel design further enhances performance and redundancy by allowing independent operation of two sets of drives. This controller is a valuable component for building reliable and efficient storage subsystems in Dell server environments.
