- Easy Management: The card is managed through HPE's Smart Array Controller, which provides a user-friendly interface for managing and monitoring storage devices.
- Flexibility: The card supports both SAS and SATA hard drives and solid-state drives (SSDs), providing flexibility in choosing the right storage solution for the specific use case.
- Compatibility: The card is compatible with HPE ProLiant Gen9 and Gen10 servers with an available x8 or x16 PCI-E slot.
It is important to note that the performance and scalability of the expander card will depend on the specific server and storage devices being used. It is recommended to verify the compatibility of this card with the operating system and hardware before purchasing.
RAID support and configuration optionsThe 769637-B21 HPE Smart Array 12GBPS PCI-E 3 X8 SAS Expander Card supports a variety of RAID configurations, including:
- RAID 0 (Striping) - Data is split across multiple drives, resulting in increased performance and improved read/write speeds.
- RAID 1 (Mirroring) - Data is duplicated across multiple drives, providing redundancy and data protection in case of a drive failure.
- RAID 5 (Parity) - Data is striped across multiple drives with parity information stored on one drive, providing data protection in case of a single drive failure.
- RAID 6 (Dual-Parity) - Similar to RAID 5, but with two drives dedicated to storing parity information, providing even greater data protection in case of multiple drive failures.
- RAID 10 (Striping and Mirroring) - A combination of RAID 0 and RAID 1, data is striped across multiple drives and mirrored for redundancy and data protection.
- RAID 50 (Parity and Striping) - A combination of RAID 5 and RAID 0, data is striped across multiple drives with parity information stored on one drive, providing improved performance and data protection in case of a single drive failure.
- RAID 60 (Dual-Parity and Striping) - A combination of RAID 6 and RAID 0, data is striped across multiple drives with two drives dedicated to storing parity information, providing improved performance and data protection in case of multiple drive failures.
The card also supports JBOD (Just a Bunch of Disks) mode, which allows for multiple drives to be used independently without any RAID configuration. It can support up to 8 internal SAS/SATA ports for connecting hard drives or SSDs.
It is designed for use with HPE ProLiant Servers and HPE Synergy Compute Module, it is important to check the compatibility of the card with the specific server model and operating system before purchasing.
