In the world of IT and data storage, the Dell 405-AAUZ Serial-Attached SCSI (SAS) PERC H745 RAID Front Controller stands as a key player. This powerful hardware component plays a pivotal role in managing data storage, ensuring data integrity, and enhancing system performance. In this comprehensive guide, we'll delve into the details of the Dell 405-AAUZ SAS PERC H745, breaking down its specifications, features, and how it contributes to the smooth functioning of your system.
Serial-Attached SCSI (SAS)
The term "Serial-Attached SCSI" may sound complex, but it essentially refers to a technology used for connecting and transferring data between hard drives and the system. SAS provides a high-speed, reliable connection that is particularly vital in enterprise-level storage solutions. The Dell 405-AAUZ is equipped with SAS, which allows it to communicate effectively with hard drives in your storage setup.
PERC stands for "PowerEdge RAID Controller," and the H745 is a specific model designed by Dell. RAID, which stands for "Redundant Array of Independent Disks," is a technology that allows multiple hard drives to work together, providing data redundancy and improved performance. The PERC H745 is an integral part of this setup, responsible for managing the RAID array and ensuring data security.
12 Gigabytes Per Second (GBPS)
This impressive data transfer rate signifies the speed at which the Dell 405-AAUZ SAS PERC H745 can move data between the system and connected storage devices. The 12 GBPS speed ensures swift data access, retrieval, and storage, making it ideal for data-intensive applications and large-scale data centers.
Peripheral Component Interconnect Express (PCI-E) 3.0
The Dell 405-AAUZ SAS PERC H745 connects to your computer's motherboard via a PCI-E 3.0 slot. PCI-E, short for Peripheral Component Interconnect Express, is a high-speed interface that allows for seamless communication between various hardware components. The choice of PCI-E 3.0 ensures that the controller can make the most of the available bandwidth, providing optimal performance.
4GB Nv Cache
The presence of a 4GB Nv (non-volatile) cache is a significant advantage for the Dell 405-AAUZ SAS PERC H745. Cache memory is a high-speed data storage buffer that temporarily stores frequently accessed data, reducing data retrieval times. With 4GB of cache, this RAID controller can handle multiple read and write requests efficiently, enhancing overall system performance.
RAID Front Controller
The term "RAID Front Controller" indicates that the Dell 405-AAUZ SAS PERC H745 is a front-end component responsible for managing the RAID array. It plays a pivotal role in configuring RAID levels, monitoring array health, and ensuring data protection through redundancy.
