Management Complex: Memory

MEMORY

The memory devices in the management complex consist of:

•1 GB DDR2 SDRAM

•512 KB socketed flash

•8 MB soldered NOR flash (two redundant banks of 4 MB each)

•1 GB soldered NAND flash

•512 Mb or 64 MB soldered NOR flash

SDRAM

This is a specialized, socketed, 200-pin, small outline, clocked, dual in- line, memory mod- ule (SO-CDIMM). It provides Error-correcting Code (ECC) on the SDRAM memory bus oper- ating at 200 MHz. The MPC8548 detects all double-bit errors, multi-bit errors within a nibble and corrects all single-bit errors.

The 128M X 72 DDR2 SDRAM is a high-density, un-buffered SO-CDIMM. This module con- sists of nine 128x8-bit with eight banks DDR2 SDRAMs, a zero delay phase-lock loop (PLL) clock, and a 2 KB serial presence detect (SPD) EEPROM. The SDRAM starts at physical address 0000,000016.

Flash

There are several flash devices on the local bus interfacing the CPLD and MPC8548 proces- sor. The four soldered flash banks are labeled 1 through 4:

•Banks 1 and 2 are the MPC8548 U-boot banks (see “4M x 16”). These boot banks are used in the boot redirection scheme, see “Boot Device Redirection (BDR).”

•Banks 3 and 4 are physically one device, but appear in the software as two banks of 32 MB (see “64 MB x 16”). These are for general purpose storage.

512 KB x 8 (optional)

The 512 KB of 32-pin PLCC socketed flash starts at physical address FC80,000016 and is used for Engineering code. The StrataFlash (P33) features high-performance fast asynchronous access times, low power, and flexible security options.

4M x 16

The two 4 MB soldered flash devices are used for MPC8548 boot code. This redundant bank configuration allows booting from either bank in case of corruption in one bank. See “Boot Device Redirection (BDR)” on page 7-41.The SST NOR flash devices are organized as 4Mx8

ATCA-9305 specifications

The Emerson ATCA-9305 is a high-performance AdvancedTCA (ATCA) chassis designed to meet the demanding requirements of telecommunications and IT infrastructure. With a focus on scalability, reliability, and flexibility, this equipment is ideal for service providers and enterprises looking to deploy robust applications in a variety of environments.

One of the main features of the ATCA-9305 is its support for high-density blade configurations. The chassis can accommodate up to 14 ATCA blades, enabling the deployment of powerful processing units, communication modules, and storage solutions. 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.
