Description
Product overview
The N743J Dell Perc H800 PCI-Express SAS Raid Controller is a high-performance storage controller designed for enterprise-level applications. This controller is equipped with a 512MB cache that helps improve the system’s performance, making it a suitable solution for data-intensive applications such as virtualization, database management, and backup and recovery. In this article, we will explore the features and benefits of the Dell Perc H800 SAS Raid Controller.
PCI-Express Interface
The Dell Perc H800 SAS Raid Controller is designed to interface with the host computer via the PCI-Express interface. This interface offers high bandwidth and low latency, which are essential for high-performance storage applications. The PCI-Express interface is also backward compatible with previous generations of PCI interfaces, which makes it compatible with a wide range of computer systems.
SAS Interface
The Dell Perc H800 SAS Raid Controller features an SAS interface that allows it to communicate with SAS or SATA hard drives. SAS drives are designed for high-performance storage applications and are ideal for use in enterprise-level systems. The SAS interface offers high-speed data transfer rates of up to 6Gbps per channel, making it suitable for applications that require fast data access.
RAID Support
The Dell Perc H800 SAS Raid Controller supports RAID levels 0, 1, 5, 6, 10, 50, and 60. RAID, which stands for Redundant Array of Independent Disks, is a technology that combines multiple hard drives into a single logical unit for improved performance, data redundancy, and data protection. RAID 0 offers improved performance by striping data across multiple drives, while RAID 1 offers data redundancy by mirroring data across two drives. RAID 5, 6, 50, and 60 offer both improved performance and data redundancy.
512MB Cache
The Dell Perc H800 SAS Raid Controller is equipped with a 512MB cache that helps improve the system’s performance. The cache stores frequently accessed data, which reduces the number of times the controller needs to access the hard drives. This helps improve the overall performance of the system, especially in applications that require frequent data access.
Battery Backup Unit
The Dell Perc H800 SAS Raid Controller comes with an optional battery backup unit (BBU) that helps protect data in the event of a power failure. The BBU is designed to provide power to the controller’s cache in the event of a power failure, which helps ensure that the data stored in the cache is not lost. The BBU can provide power for up to 72 hours, which gives the user enough time to recover from a power failure.
Compatibility
The Dell Perc H800 SAS Raid Controller is compatible with a wide range of operating systems, including Windows, Linux, and VMware. This makes it suitable for use in a wide range of enterprise-level applications. The controller is also compatible with a wide range of Dell PowerEdge servers, including the PowerEdge R710, R810, R910, M910, and T710.
In Summary,The N743J Dell Perc H800 PCI-Express SAS Raid Controller is a high-performance storage controller designed for enterprise-level applications. It features a 512MB cache that helps improve the system’s performance, and supports RAID levels 0, 1, 5, 6, 10, 50, and 60 for improved data redundancy and data protection. The controller is compatible with a wide range of operating systems and Dell PowerEdge servers, which makes it suitable for use in a wide range of applications. Overall, the Dell Perc H800 SAS Raid Controller is an excellent choice for anyone looking for a high-performance storage controller for enterprise-level applications.
