The SAS3x40 is a SAS expander manufactured by Broadcom (formerly Avago Technologies). This device increases the number of SAS and SATA devices that can be connected to a SAS controller. SAS expanders are essential in storage systems requiring high density and scalability, enabling efficient management of numerous storage devices.

Applications:

• Storage Arrays (SAN, NAS)
• High-Density Servers
• JBOD (Just a Bunch Of Disks) Systems
• Tape Libraries
• Enterprise Data Centers
• Cloud Storage Infrastructure
• Video Surveillance Systems

Features:

• 40 Ports
• 12 Gbps SAS data transfer rates
• Supports SAS and SATA devices
• Zoning Support
• SES-2 Enclosure Management
• SGPIO (Serial General Purpose Input/Output) support
• Hot-Plug support

Benefits:

• Increased storage capacity by allowing connection of more devices
• High data transfer rates for improved storage performance
• Flexible storage configuration options
• Simplified storage management using enclosure management features
• Hot-plug support simplifies maintenance and reduces downtime
• Scalable storage solutions to accommodate growing data needs
• Reduced complexity compared to using multiple SAS controllers

Relevant Additional Details:

The SAS3x40 SAS expander enables the connection of up to 40 SAS or SATA drives to a single SAS controller. Zoning support allows the partitioning of the storage system for enhanced security and manageability. SES-2 (SCSI Enclosure Services) support enables the monitoring and control of the storage enclosure. SGPIO provides a standardized interface for communication between the expander and the backplane. Designed for high reliability, the SAS3x40 is suitable for enterprise environments requiring robust and scalable storage solutions. It supports a range of operating systems and RAID configurations, providing a flexible and efficient storage infrastructure.
