The HPE Smart Array E208I-A (804326-B21) controller is compatible with a wide range of SAS and SATA hard drives and solid-state drives (SSDs). The controller supports both 2.5-inch and 3.5-inch drive form factors and can be used in both internal and external storage configurations.
It supports a maximum of 8 SAS or SATA drives and can be connected to SAS or SATA drive backplanes. The E208I-A controller supports SAS and SATA drives with a maximum capacity of 10TB. It also supports SAS and SATA drives with a maximum data transfer rate of 12 Gbps.
In addition, the controller supports advanced features such as online RAID level migration and expansion, allowing you to easily upgrade your storage capacity or change your RAID level without having to take your server or storage system offline.
It's important to note that the E208I-A controller only supports SAS and SATA drives, it does not support NVMe drives. Additionally, it is recommended to use HPE-branded drives for optimal compatibility and performance.
Performance and Scalability
The HPE Smart Array E208I-A (804326-B21) controller provides basic RAID functionality and performance for small to medium-sized businesses. It is designed to handle the storage needs of entry-level servers and storage systems.
The controller supports a maximum data transfer rate of 12 Gbps, which is the standard for SAS drives. This allows for fast data transfer and improved overall system performance. It also comes with an HPE Smart Storage Battery which provides power to the controller cache in the event of a power failure, helping to protect data integrity.
In terms of scalability, the E208I-A controller supports up to 8 SAS or SATA hard drives or solid-state drives. This allows for flexible storage capacity options, depending on the needs of your business. Additionally, the controller supports advanced features such as online RAID level migration and expansion, allowing you to easily upgrade your storage capacity or change your RAID level without having to take your server or storage system offline.
It's important to note that the controller's performance and scalability are limited by the number of drives and the RAID level used. For example, RAID 0 provides the highest performance but no data redundancy, while RAID 1 provides data redundancy but lower performance.
The HPE Smart Array E208I-A controller provides basic RAID functionality and performance for small to medium-sized businesses. It supports fast data transfer, flexible storage capacity options, and advanced features for easy scalability, but its performance and scalability may not be sufficient for larger organizations or demanding workloads.
