Frequently Asked Questions
What is a 24-port SAS controller used for?
A 24-port SAS controller like the Broadcom 9305-24I connects multiple storage drives directly to a server or storage appliance. It's essential for building high-capacity direct-attached storage (DAS) systems, enabling organizations to attach up to 24 drives per adapter for databases, virtualization, backup, and archival workloads.
Can the SAS 9305-24I support both HDDs and SSDs?
Yes. The SAS 9305-24I HBA supports both SAS and SATA HDDs as well as SAS and SATA SSDs, providing flexibility to mix drive types based on performance and capacity requirements. This compatibility makes it ideal for hybrid storage configurations.
What throughput does the 12 Gb/s SAS adapter deliver?
The 12 Gb/s SAS adapter achieves up to 6,400 MBps aggregate bandwidth across all 24 ports, with individual ports supporting 12 Gb/s. Combined with over 1.5 million IOPs, it handles intensive I/O workloads including virtualization, databases, and real-time analytics.
Is the SAS 9305-24I compatible with SAS expanders?
Yes. The Broadcom 24-port SAS controller supports SAS expanders, allowing you to extend connectivity beyond 24 drives. This enables scalable storage architectures for growing enterprise environments without requiring additional controller cards.
