The Dell 405-AAER Perc H830 SAS Controller is a high-performance storage controller designed for use in Dell PowerEdge servers. This PCIe 3.0 SAS controller is designed to work with Dell's PowerEdge RAID Controller (PERC) firmware and provides a variety of features that enhance data protection, storage capacity, and performance.
One of the key features of the Dell 405-AAER Perc H830 SAS Controller is its 2GB NV Cache, which provides faster access to frequently accessed data and helps to reduce latency. This storage controller also offers RAID support for various RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50, which provides flexible options for managing data redundancy and protection.
In this article, we will delve deeper into the features and benefits of the Dell 405-AAER Perc H830 SAS Controller, explaining how it can help improve the storage performance and reliability of your Dell PowerEdge server.
PCI-Express 3.0 InterfaceThe Dell 405-AAER Perc H830 SAS Controller is designed to work with the PCIe 3.0 interface, which offers faster data transfer speeds than previous PCIe versions. PCIe 3.0 provides a maximum data transfer rate of 8 GT/s (gigatransfers per second), which is twice the speed of PCIe 2.0.
The faster data transfer rates offered by PCIe 3.0 can help to reduce latency and improve overall system performance. This is particularly beneficial for storage controllers, which need to access large amounts of data quickly and efficiently.
SAS InterfaceThe Dell 405-AAER Perc H830 SAS Controller uses the Serial Attached SCSI (SAS) interface, which is a high-performance interface designed for use in servers and other enterprise-level storage systems. SAS offers several advantages over other storage interfaces, including higher data transfer rates, greater scalability, and improved reliability.
SAS is also designed to work with a wide range of storage devices, including hard disk drives (HDDs), solid-state drives (SSDs), and tape drives. This makes it a versatile choice for enterprise storage applications.
2GB NV CacheThe Dell 405-AAER Perc H830 SAS Controller is equipped with a 2GB Non-Volatile (NV) Cache, which is a type of memory that retains data even when the system is powered off. NV cache provides faster access to frequently accessed data and helps to reduce latency.
The NV cache used in the Dell 405-AAER Perc H830 SAS Controller is also designed to be more reliable than other types of cache. This is because NV cache uses flash memory, which is less prone to data loss due to power failures or other types of system failures.
RAID SupportThe Dell 405-AAER Perc H830 SAS Controller offers support for a wide range of RAID levels, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, and RAID 50. RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives into a single logical unit, providing improved data redundancy, performance, and capacity.
RAID 0 is a striping configuration that offers improved performance by dividing data across multiple hard drives. RAID 1 is a mirroring configuration that provides data redundancy by writing the same data to multiple hard drives. RAID 5 and RAID 6 are parity configurations that provide data redundancy by using parity information to reconstruct data in the event of a hard drive failure. RAID 10 is a combination of RAID 0 and RAID 1, providing both improved performance and data redundancy. RAID 50 is a combination of RAID 5 and RAID 0, providing improved performance
