VSC7155XVU-02 Description

Short technical summary and product information.

The VSC7155XVU-02 is a user-configurable, multimode 18-PHY Serial Attached SCSI (SAS) expander designed for embedded applications in midrange and enterprise storage environments. It provides SAS port expansion according to ANSI T10 Serial Attached SCSI 1.0 and 1.1 specifications, functioning as both an edge and fanout expander.

This expander supports data rates of 1.5Gbps and 3.0Gbps, featuring an internal non-blocking cross-bar matrix for up to 18 connected PHYs. It includes programmable output preemphasis and input signal equalization for consistent signal quality. The integrated v3000 CPU handles SMP management functions, and the device supports various interfaces including I2C, Ethernet, SMP, UART, and SGPIO.

Targeted for systems like blade servers, JBODs, and RAID systems, the VSC7155XVU-02 offers an upgrade path from parallel SCSI technology. It is suitable for distributing SAS signals to disk drive arrays. Note that this product is not recommended for new designs and some versions may be discontinued.

Key features include 18 PHYs, support for 1.5Gbps and 3.0Gbps SAS, and integrated enclosure management capabilities. The device is designed to ensure high-performance characteristics and industry-leading high-speed inputs/outputs.
