Compatible With: MSA60 Storage Units

The HP AG779A Dual SAS I/O Module is a versatile and reliable solution for users who need to expand the storage capacity of their servers. One of its key features is its compatibility with MSA60 Storage Units. In this section, we will explore the benefits and importance of this compatibility for users.

Increased Storage Capacity

By being compatible with MSA60 Storage Units, the HP AG779A Dual SAS I/O Module allows users to easily expand their server's storage capacity. The MSA60 Storage Units provide a high-density solution, enabling users to add multiple hard drives to their server without taking up excessive rack space. This increased storage capacity is especially valuable for businesses that deal with data-intensive applications or require large amounts of storage for their operations.

With the ability to connect multiple MSA60 Storage Units to the Dual SAS I/O Module, users can significantly enhance their server's storage capabilities. Whether it is for storing large databases, multimedia files, or backups, having access to ample storage space ensures that users can meet their data storage needs efficiently and effectively.

Flexible and Scalable Solution

The compatibility with MSA60 Storage Units makes the HP AG779A Dual SAS I/O Module a flexible and scalable solution. Users can start with a smaller storage configuration and easily expand it as their needs grow. This scalability is particularly beneficial for businesses that anticipate future growth or have fluctuating storage requirements.

The MSA60 Storage Units can be easily added or removed from the Dual SAS I/O Module without disrupting the server's operation. This hot-swappable feature allows users to add or replace drives on-the-fly, minimizing downtime and ensuring continuous availability of data. This flexibility enables businesses to adapt quickly to changing demands, whether it is adding more storage for new projects or replacing faulty drives.

Improved Data Redundancy and Fault Tolerance

The HP AG779A Dual SAS I/O Module, in combination with MSA60 Storage Units, offers enhanced data redundancy and fault tolerance. The Dual SAS ports allow for redundant connections, ensuring that data can still be accessed even if one port fails. This redundancy is crucial for businesses that cannot afford any interruption in their data access or face the risk of data loss.

In addition, the compatible MSA60 Storage Units support RAID configurations. RAID (Redundant Array of Independent Disks) provides various levels of data redundancy and fault tolerance. By configuring the MSA60 Storage Units in RAID, users can protect their data from drive failures and ensure the integrity of their critical information. This feature is particularly important for businesses that handle sensitive data or rely heavily on continuous access to their stored information.

RAID Levels Supported:

RAID 0

RAID 0 striping provides improved performance by spreading data across multiple drives. This level of RAID does not provide redundancy but offers increased read and write speeds, making it suitable for applications that require high-speed data access.

RAID 1

RAID 1 mirroring duplicates data across two drives, providing redundancy in case of a drive failure. This level of RAID ensures that data remains accessible even if one drive fails. It is ideal for businesses that prioritize data protection and fault tolerance.

RAID 5

RAID 5 combines striping and parity to achieve both increased performance and fault tolerance. Data is spread across multiple drives, and parity information is distributed across all the drives. In case of a drive failure, the parity information allows for data reconstruction. RAID 5 is commonly used in environments that require a balance between performance and redundancy.

Redundant Power Supply

The HP AG779A Dual SAS I/O Module features a redundant power supply, which further enhances its reliability. In the event of a power supply failure, the redundant power supply ensures that the module continues to function without interruption. This redundant power supply is critical for businesses that cannot afford downtime or data loss due to power issues.

Features: Dual SAS ports, Hot-swappable, Redundant power supply, Supports RAID configurations

The HP AG779A Dual SAS I/O Module offers a range of features that are essential for users seeking reliable and efficient storage expansion solutions. In this section, we will delve into the benefits and importance of these features.

Dual SAS Ports

The Dual SAS ports on the HP AG779A Dual SAS I/O Module enable users to connect multiple storage units simultaneously. This feature allows for increased data transfer rates and improved overall system performance. With two ports, users can distribute the data flow across both connections, reducing bottlenecks and ensuring efficient data access.

By utilizing both SAS ports, users can also achieve redundancy in case of a port failure. The ability to have multiple connections ensures that data can still be accessed even if one port becomes unavailable. This redundancy is crucial for businesses that require continuous access to their stored data and cannot afford any interruption due to hardware failures.

Hot-swappable

The hot-swappable capability of the HP AG779A Dual SAS I/O Module allows for easy installation and replacement of storage units without disrupting the server's operation. Users can add or remove MSA60 Storage Units on-the-fly, eliminating the need for system shutdowns or downtime.

This hot-swappable feature is particularly beneficial for businesses that require high availability and cannot afford interruptions in their data access. Whether it is for adding more storage capacity or replacing faulty drives, the ability to perform these operations without affecting the server's operation ensures continuous availability of data and minimizes potential disruptions.

Redundant Power Supply

The redundant power supply of the HP AG779A Dual SAS I/O Module adds an extra layer of reliability to the storage expansion solution. In the event of a power supply failure, the redundant power supply ensures that the module continues to function without interruption. This feature is crucial for businesses that cannot afford any downtime or data loss due to power issues.

With a redundant power supply, users can have peace of mind knowing that their storage units will remain operational even if one power supply fails. This redundancy is especially important for businesses that rely heavily on continuous access to their stored data or handle critical information.

Supports RAID Configurations

The HP AG779A Dual SAS I/O Module is compatible with MSA60 Storage Units that support various RAID configurations. RAID provides enhanced data redundancy and fault tolerance, ensuring the integrity of critical information and minimizing the risk of data loss.

By configuring the MSA60 Storage Units in RAID, users can choose the level of redundancy and performance that best suits their needs. Whether it is striping data across multiple drives (RAID 0) to improve performance or mirroring data (RAID 1) for redundancy, the ability to utilize RAID configurations adds another layer of data protection and reliability to the storage solution.

Conclusion

The HP AG779A Dual SAS I/O Module's compatibility with MSA60 Storage Units offers users a versatile and reliable solution for expanding their server's storage capacity. With increased storage capacity, flexibility, improved data redundancy, and fault tolerance, as well as features like dual SAS ports, hot-swappability, redundant power supply, and support for RAID configurations, the HP AG779A Dual SAS I/O Module is an ideal choice for businesses that require efficient and scalable storage expansion solutions.
