Management Complex: PCI

in a dual-bank architecture for concurrent read/write operation with hardware and software data protection schemes. These devices start at physical addresses F000,000016 (boot bank 1) and F040,000016 (boot bank 2).

1 GB x 16

The ATCA-9305 uses 1 GB of M-Systems DiskOnChip (mDOC H3) NAND flash starting at physical address FC00,000016 for non-volatile RAM storage and True Flash File System (TFFS). This memory incorporates an embedded flash controller and memory, and includes hardware protection and security-enabling features, an enhanced programmable boot block enabling eXecution In Place (XIP) functionality using 16-bit access, user-controlled One Time Programmable (OTP) partitions, and 6-bit Error Detection Code/Error Correction Code (EDC/ECC).

64 MB x 16

The 64 MB soldered NOR flash starts at physical address F400,000016 (bank 3). The 64-Mbit

P33 device provides CN5860 code storage and non-volatile memory.

PCI

The MPC8548 performs all the functions of a PCI host and monarch, and handles all arbitra- tion and enumeration functions. PCI starts at physical address 8000,000016.

The PCI bus connects to both Cavium processors, the MPC8548 processor and the Broad- com Ethernet switch, see Table 4-4. All of the devices on the PCI bus can operate at 66 MHz and perform 64-bit transactions in conventional PCI mode except for the Broadcom switch. The switch has a 32-bit PCI bus.

The MPC8548 stores the Cavium CN5860 operating system and monitor code in local memory and then uses the boot over PCI functionality to bring up the CN5860 processor complexes.

This level of density not only maximizes space but also minimizes power consumption, which is crucial for reducing operational costs in large-scale deployments.

The ATCA-9305 is built with a focus on advanced thermal management and redundancy. It employs a sophisticated cooling architecture that ensures optimal airflow across the chassis, preventing overheating during operation. Additionally, the chassis features hot-swappable fans and power supplies, which means that components can be replaced without interrupting the overall system performance. This capability enhances uptime and reliability, which is essential for mission-critical applications.

Another notable characteristic of the ATCA-9305 is its support for various interconnect technologies. The chassis provides robust backplane options that facilitate high-bandwidth communication between blades. It supports Ethernet, PCI Express, and Serial RapidIO, allowing for seamless integration with existing infrastructure and future technologies. This flexibility enables organizations to adapt to changing market demands and technological advancements.

Security features are also a prominent aspect of the ATCA-9305. The chassis incorporates hardware-based security modules that enhance data integrity and protect sensitive information. This is particularly important for service providers who must adhere to strict regulatory compliance standards.

In terms of management and monitoring, the ATCA-9305 is equipped with advanced management capabilities. It supports AdvancedTCA Management Interface (IPMI) and other monitoring protocols, allowing administrators to easily oversee the health and performance of the entire system. This level of visibility aids in proactive maintenance and troubleshooting, effectively reducing downtime.

In conclusion, the Emerson ATCA-9305 is a powerful and versatile chassis that stands out due to its high-density configuration, advanced thermal management, diverse interconnect technology support, robust security features, and comprehensive management capabilities. Its design is tailored for the evolving needs of telecommunications and data center environments, making it a valuable asset for any organization looking to enhance its infrastructure.
