2-2 Sun Netra CP3000 Advanced Mezzanine Card PCIe Hard Drive and SAS Controller User’s Guide • March 2010
2.1 Features
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:
■ PICMG AMC.0 Rev. 2.0
■ AMC.1 Revision 1, PCI Express option
■ AMC.3 Revision 1, storage signaling option
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:
■ Advanced Mezzanine Card (single-width, mid- or full-height); PICMG AMC.0
