Its 12Gbps data transfer rate is particularly beneficial for handling the vast amounts of data generated in HPC applications.
Scalability
The HPE P440AR SAS Smart Array Controller Card (part number 749796-001) is designed to be highly scalable for HPE ProLiant servers. Scalability in this context refers to the ability of the storage controller to grow and adapt to the changing storage needs of an organization.
One of the key scalability features of the controller is its ability to support online capacity expansion. This feature allows you to add more hard drives to the system without disrupting access to the data. This means that you can increase your storage capacity without any downtime. This feature enables you to easily expand your storage as your needs grow.
The controller also supports online RAID level migration, which allows you to change the RAID level of a virtual disk without disrupting access to the data. This flexibility to change the RAID level based on the changing storage needs of your organization. This enables you to adapt your RAID level to your changing storage needs.
Additionally, the controller supports multiple paths to the storage array, which provides redundancy and improves availability in case of a host adapter failure. The controller supports both SAS and SATA hard drives, and it can be used to create multiple virtual disks, each with its own RAID level. This allows you to create multiple storage pools and assign different RAID levels to each pool, enabling you to optimize the storage for different workloads.
Performance and Reliability of Smart Array
The HPE P440AR SAS Smart Array Controller Card (part number 749796-001) is designed to provide both high performance and reliability for HPE ProLiant servers. It has two internal 12 Gb/s SAS ports and supports RAID levels 0, 1, 5, 6, 10, 50, and 60. These RAID levels provide different levels of data protection and redundancy. RAID levels such as RAID 5, 6, 10, and 50 provide better performance and reliability compared to other RAID levels as they use striping and parity data to protect data in case of hard drive failure and improve read and write operations.
The controller also supports advanced data security options such as RAID ADG (Advanced Data Guarding) and RAID 60 which provide even more robust data protection and improve the overall reliability of the controller. This means that in case of a single drive failure, your data is still protected and the controller can continue to function normally.
The controller also supports online RAID level migration, which allows you to change the RAID level of a virtual disk without disrupting access to the data. This flexibility to change the RAID level based on the changing storage needs of your organization, and can help to optimize the performance and reliability of the controller.
The controller also supports online capacity expansion, which allows you to add more hard drive to the system without disrupting access to the data. This enables you to easily increase your storage capacity without any downtime and improve the performance and reliability of the controller.
