The JMicron JMB363-LGAZ0C is a single-chip SATA II port multiplier and RAID controller. It allows a single SATA port on a host system to connect to multiple SATA drives, and also provides RAID functionality for improved performance or data redundancy.

Applications

• NAS (Network Attached Storage) Devices: Expanding storage capacity and providing RAID functionality.
• RAID Storage Systems: Building cost-effective RAID storage solutions.
• Desktop PCs: Adding multiple SATA ports and RAID capabilities to desktop computers.
• Server Storage: Providing storage expansion and RAID support for servers.
• External Storage Enclosures: Creating multi-drive external storage solutions with RAID support.

Features

• SATA II Support: Supports SATA II data transfer rates (3.0 Gbps).
• Port Multiplication: Enables multiple SATA drives to be accessed through a single SATA port.
• RAID Support: Supports RAID levels 0, 1, and possibly 10 (check datasheet for confirmation).
• FIS-based Switching: Uses FIS-based switching for efficient data transfer.
• PCI Express Interface: Connects to the host system via PCI Express.

Benefits

• Increased Storage Capacity: Expands storage capacity by allowing multiple drives to be connected to a single SATA port.
• Improved Performance: RAID 0 provides increased read and write speeds.
• Data Redundancy: RAID 1 provides data redundancy by mirroring data across multiple drives.
• Simplified Storage Management: Simplifies storage management with RAID functionality.
• Cost-Effective Storage Solution: A cost-effective solution for expanding storage capacity and adding RAID support.

Additional Details

The JMB363-LGAZ0C typically supports up to five SATA drives through a single host SATA port. It supports both command-based and FIS-based switching. Power consumption is generally low, which is ideal for storage systems. Consult the JMicron datasheet for detailed technical specifications and supported RAID levels.
