VSC7155XVU-02

Overview

The VSC7155XVU-02 is a multimode, user-configurable 18-PHY Serial Attached SCSI (SAS) expander supporting ANSI T10 SAS 1.0 and 1.1 specifications for edge and fanout topologies. It features an internal nonblocking cross-bar matrix connecting up to 18 PHYs, each operating independently at 1.5Gbps or 3.0Gbps. The device includes 18 10-bit serializer/deserializers (SerDes), retiming elasticity buffers, and table routing for up to 320 destination addresses. An embedded Stanford-1 32-bit RISC CPU manages enclosure functions via I²C, Ethernet, or SMP interfaces.

Feature Summary

Supports both SAS edge and fanout expander configurations with independent per-PHY speed operation.
Features a nonblocking switch architecture enabling any-to-any PHY connectivity.
Integrates an embedded enclosure management processor for local control and SES functions.
Provides programmable output deemphasis and input signal equalization for high-speed signal integrity.

Applications

Blade servers
JBOD arrays
Enterprise storage environments
Rack-mounted servers with RAID

Procurement Notes

Verify the Last Time Buy status before procurement planning. Confirm package compatibility with the 448-pin BGA form factor. Ensure design migration strategies are in place due to discontinuation risks associated with legacy parallel SCSI upgrades.

Selection Notes

Select this component for systems requiring 18-port SAS expansion with integrated SerDes. Verify support for required SAS 1.0/1.1 compliance and specific topology needs such as fanout versus edge configurations. Evaluate the need for embedded enclosure management capabilities over external controllers.

Part Context

This part belongs to the VSC7155 family of SAS expanders designed for midrange and enterprise storage. It serves as a technology upgrade for systems transitioning from parallel SCSI to serial architectures while maintaining software compatibility.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer obsolescence notices for potential lifecycle alternatives.
