Comprehensive RAID Protection

The Dell 405-AAWX RAID controller provides robust protection for your storage setup. RAID (Redundant Array of Independent Disks) offers fault tolerance, which ensures that data is protected against hardware failures. By employing different RAID levels, such as RAID 1 for mirroring and RAID 5 for distributed parity, users can choose the right balance of performance, redundancy, and storage capacity for their unique needs.

RAID Levels Supported by Dell 405-AAWX

RAID 0 - Stripping for Speed

RAID 0 is designed for environments where speed is paramount. It distributes data across multiple drives, offering enhanced performance, but lacks redundancy. It is ideal for applications with large sequential data reads or writes, such as video editing or scientific computing.

RAID 1 - Mirroring for Data Redundancy

RAID 1 provides data redundancy by mirroring data across two drives. It’s an excellent choice for applications requiring high availability. If one drive fails, the system continues to operate with no data loss, as the information is duplicated on the second drive.

RAID 5 - Striping with Parity for Fault Tolerance

RAID 5 provides a good balance between performance, redundancy, and storage efficiency. Data is striped across multiple disks with distributed parity, allowing recovery from a single drive failure without losing any data. This is often used in business environments where both speed and data protection are essential.

RAID 6 - Dual Parity for Maximum Fault Tolerance

RAID 6 builds upon RAID 5 by adding a second layer of parity, offering protection against two simultaneous disk failures. While it requires more storage overhead, it ensures that critical data remains accessible in the event of multiple drive failures, making it ideal for high-availability systems.

RAID 10 - Combining Striping and Mirroring

RAID 10 combines the benefits of both RAID 1 and RAID 0. It offers data redundancy and performance by mirroring data across two sets of drives while striping the data within each set. This results in a highly resilient and fast storage solution.

RAID 50 - Combining RAID 5 and RAID 0

RAID 50 combines the benefits of RAID 5 with the performance advantages of RAID 0. It offers both redundancy and speed by grouping multiple RAID 5 arrays into a larger RAID 0 array, ideal for applications with high throughput requirements and fault tolerance needs.

4GB NV Cache for Enhanced Performance

The Dell 405-AAWX PERC H745 includes 4GB of NV (Non-Volatile) Cache, which helps to accelerate data access times. NV cache retains data even in the event of power loss, ensuring that write operations are completed without corruption. This is particularly important for environments that demand high performance, such as virtualization and large-scale databases. With its advanced cache management algorithms, the Dell RAID controller optimizes read and write operations, contributing to overall system performance.

How NV Cache Works

When data is written to a storage system, the RAID controller temporarily stores it in the NV cache. This allows for faster response times as data can be quickly retrieved from the cache rather than being read from disk. Additionally, when power is restored after an unexpected shutdown, the cached data is safely written to the disk, ensuring consistency and avoiding data loss.

Flexible Storage Configuration Options

The Dell 405-AAWX PERC H745 RAID controller offers several configuration options to suit a variety of storage setups. It supports multiple drives, including SAS and SATA, and can manage large storage volumes, making it a versatile choice for different data center environments. Additionally, the controller can be used to configure JBOD (Just a Bunch of Disks), allowing users to configure storage in a way that suits their needs.

Compatibility with SAS and SATA Drives

Supporting both SAS and SATA drives, the Dell 405-AAWX allows users to build storage arrays with a combination of high-performance SAS drives and cost-effective SATA drives. SAS drives offer faster speeds and better durability, while SATA drives provide greater storage capacity at a lower cost. This flexibility ensures that organizations can meet their performance and budget requirements without compromising on reliability.

Enterprise-Level Management with OpenManage Integration

The Dell 405-AAWX PERC H745 integrates with Dell’s OpenManage suite of management tools, allowing administrators to monitor and manage storage systems easily. OpenManage provides a centralized platform for hardware health monitoring, firmware updates, and configuration management. This integration simplifies the administration of RAID arrays and ensures that issues are quickly identified and addressed before they lead to system failures.

Benefits of OpenManage Integration

By using OpenManage, IT teams can reduce the time spent on manual maintenance tasks. Alerts and notifications help administrators proactively address hardware issues, improving uptime and reducing operational costs. With detailed performance statistics and system diagnostics, administrators can fine-tune configurations for optimal performance.

High-Speed Connectivity with PCI-E 3.0

The Dell 405-AAWX PERC H745 is equipped with PCI-E 3.0 connectivity, offering higher bandwidth for faster data transmission. This interface supports speeds of up to 12GBPS, providing the throughput necessary for demanding applications such as database management, high-performance computing, and virtualization. PCI-E 3.0 is backward compatible with older PCI-E versions, ensuring compatibility with a wide range of systems.

Benefits of PCI-E 3.0

PCI-E 3.0 offers improved data transfer speeds and efficiency compared to earlier versions. This results in better overall performance for storage operations, particularly in environments with high data throughput demands. With PCI-E 3.0, users can expect faster access to data and more efficient use of system resources, allowing for better performance across a variety of applications.

Compatibility with Dell PowerEdge Servers
