Overview |
This chapter introduces the key features of the AMC. This chapter includes a product definition, a list of product features, and functional block diagrams with brief descriptions. This chapter can be used to compare the features of the AMC against the needs of a specific application.
This chapter contains the following topics:
Part of Sun’s ATCA platform, the Sun Netra CP3000 AMC.1-HDD SAS disk complies with PICMG 3.0 AdvancedTCA Specification R2.0 ECN002 and the following specifications:
The AMC.1-HDD SAS disk is an Advanced Mezzanine Card (AMC) that integrates both an SAS hard drive disk and a x4 PCIe SAS controller. Occupying only one AMC site, the highly integrated combination provides embedded systems designers the ability to add an Enterprise SAS Hard Disk Drive (HDD) to a system that does not have native SAS connectivity. The AMC.1-HDD SAS disk is offered as a single-width AMC, with options for mid- or full-height panels. The hard drive is Form-Factor 2.5” to provide the greatest spindle density for ATCA applications.
The AMC.1-HDD SAS disk plugs into ATCA carrier blades that support a combination of AMC.1 (PCI Express) and AMC.3 (SAS) storage signaling.
The AMC.1-HDD SAS disk includes a modular management controller (MMC).
This AMC is designed for use in a wide variety of next-generation and wireless-networking equipment. Designed for high performance and reliability, the AMC.1-HDD SAS disk is ideal for telecommunications equipment manufacturers (TEMs) and OEMs. TEMs can add SAS connectivity to networking equipment that uses the ATCA platform specification. OEMs can design to the MicroTCA specification for high-performance embedded systems.
The following briefly outlines the features of the AMC.1-HDD SAS disk:
The following figure and sections describe key components of the Sun Netra CP3000 AMC.1-HDD SAS disk.

The Sun Netra CP3000 AMC.1-HDD SAS disk provides a single SAS hard drive, with various capacity options available. When you order the product, choose the part number corresponding to the capacity (in gigabytes) that you want.
The power regulator is the part of the module that generates the required power from the payload power (+12V) that is delivered to the module through the AMC connector. This power is current-limited by the onboard regulator.
The AMC.1-HDD SAS disk incorporates a PCIe-to-SAS host controller manufactured by LSI Corporation, device model LSI-SAS1064E. The controller provides host access to SAS and SATA disks. The controller features four lanes of PCI Express (2.5 gigabits per second each), and four lanes of SAS (3.0 gigabits per second each).
The SAS firmware for the LSI SAS supports the following:
A flash device is preloaded with firmware that manages the protocols necessary to communicate with SAS and SATA target devices. The flash device contains BIOS and F-code to support boot from disk operations.
The IPMI subsystem provides management control for the board, based on an Atmel microcontroller. The MMC is the first system component to be brought up and must negotiate with the carrier board over IPMI before the card payload is enabled.
The MMC monitors board voltages and temperature, controls the hot-swap and failures status LEDs, controls e-Keying, and stores FRU information. For more information about the MMC and management functions, see Chapter 3.
The MMC provides an Intelligent Platform Management Interface (IPMI) that communicates with AdvancedTCA shelf managers. This MMC controls and monitors the following:
The AMC includes connectors to communicate with the host board and take its interfaces outside the ATCA chassis. Refer to Appendix A for complete connector descriptions and pin-outs.
The AMC.1-HDD SAS disk has three LEDs. See the next section for a detailed description of the LEDs.
The faceplate of the AMC.1-HDD SAS disk has three LED indicators, which are described in the table following the faceplate illustration.
| Note - The AMC is available in different capacities (in gigabytes). The illustration shows a generic faceplate. For your product’s faceplate, the xxx denotes the capacity. |
