Description
Product overview of the Dell RDH6Y
The Dell RDH6Y PERC H840 PCI-E 3.0 SAS 4GB Cache Raid Controller Card is a powerful tool for managing your data storage needs. It is a hardware device that connects to your server’s PCI-E slot and provides advanced RAID (redundant array of independent disks) functionality. This card is designed to work with SAS (Serial Attached SCSI) hard drives, which are a type of hard drive that offers high performance and reliability.
A RAID controller card is a device that manages a RAID array, which is a set of multiple hard drives that are combined to work as a single logical drive. The purpose of RAID is to improve performance and data reliability by distributing data across multiple drives. RAID is commonly used in servers and other high-end computing applications where large amounts of data need to be stored and accessed quickly.
A RAID controller card provides the necessary hardware to manage the RAID array. It is responsible for handling data reads and writes to the hard drives, as well as monitoring the health of the drives and detecting any failures. The RAID controller also provides various RAID configurations, which determine how the data is distributed across the drives.
The Dell RDH6Y PERC H840 PCI-E 3.0 SAS 4GB Cache Raid Controller Card is one such device that provides advanced RAID functionality.
The Dell RDH6Y PERC H840 PCI-E 3.0 SAS 4GB Cache Raid Controller Card is a high-performance RAID controller card that offers advanced features and functionality. It is designed to work with SAS hard drives and provides up to 4GB of cache memory, which helps to improve performance and reduce latency.
PCI-E 3.0 Interface
The card connects to your server’s PCI-E 3.0 slot, which provides high-speed data transfer rates and low latency. The PCI-E 3.0 interface is the latest standard for PCI-E, offering twice the bandwidth of the previous generation.
SAS Interface
The Dell RDH6Y PERC H840 PCI-E 3.0 SAS 4GB Cache Raid Controller Card is designed to work with SAS hard drives, which offer high performance and reliability. SAS is a type of hard drive interface that uses a point-to-point architecture, which provides better data transfer rates and less latency than traditional parallel SCSI interfaces.
4GB Cache Memory
The card provides up to 4GB of cache memory, which helps to improve performance and reduce latency. The cache memory is used to store frequently accessed data, which can be quickly retrieved without having to access the hard drives.
RAID Configurations
The Dell RDH6Y PERC H840 PCI-E 3.0 SAS 4GB Cache Raid Controller Card provides a variety of RAID configurations, which determine how the data is distributed across the hard drives. The card supports RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60 configurations.
RAID 0 – Data is striped across multiple hard drives for improved performance.
RAID 1 – Data is mirrored on multiple hard drives for data redundancy.
RAID 5 – Data is distributed across multiple hard drives with parity data for data redundancy.
RAID 6 – Similar to RAID 5 but with additional parity data for increased fault tolerance.
RAID 10 – Data is mirrored and striped across multiple hard drives for improved performance and data redundancy.
