as blades, AMCs and RTMs. The exact combination of hardware is defined by the network element architecture. ATCA embedded software; this means software that is integral to the functioning of a particular hardware unit, such as BIOS, an embedded Linux operating system and hardware management software. The main types of embedded software are introduced below in ATCA embedded software.

On top of the ATCA building blocks, network elements consist of layers of application software and, depending on network element, a software platform that provides the main operating system. Application Software platform ATCA hardware platform Embedded software Hardware DN0948687

hardware units with unit computers. This software resides in the local flash memory of each unit. Network interface SW Network interface software controls the external traffic flowing through blades and AMC modules with network interfaces. Synchronization SW (optional, included if the network element uses synchronization) Synchronization software consists of software in a system manager (on CPU blade or CPU AMC) and synchronization software in a hub blade or in a clock generator module. It is used for controlling the way in which synchronized clock signals are distributed to the rest of the units. DSP SW (optional, included if the network element does signal processing) The signal processing software on the DSP blade runs on an OSE operating system, while the unit computer runs embedded Linux. HW management SW Hardware management software consists of software related to shelf and system management, including hardware management controller firmware, shelf manager software, communication over IPMB-0 and IPMB-L, management communication over the base interface using RMCP (remote management control Protocol) and RPC (remote procedure call protocol), and remote access to blades and AMCs (serial over LAN). The HW management domain includes also FRU information storages in all hardware products that have a hardware management controller. Software management (not illustrated) Software management software handles all embedded software updates.

Benefits of ATCA The main strength of ATCA is in its versatility, its ability to support larger volumes, and its capacity to harmonise different platforms. In the long run, ATCA will allow faster time to market and lower costs in terms of both equipment and development, as it will be possible to employ a wide variety of building blocks with minimal modifications. •

Modularity and configurability ATCA allows diverse applications to be created in one platform using multiple modules with various interfaces, including CPUs, DSPs, and storage media from different manufacturers. Redundancy ATCA features many levels of redundancy throughout the system, achieving 99.999% availability (five-nines or carrier grade availability). The option to allow less demanding applications to utilise non-redundant configurations for lower cost is also possible. Support for Ethernet switching fabric ATCA specifications support various serial-type switching fabrics, such as Ethernet and PCI Express. The Nokia Siemens Networks ATCA HW platform currently uses 10 Gigabit Ethernet technology. Scalable capacity Scalability in ATCA is enabled by a centralized switching hub, interconnected to all shelf slots in a star configuration. This allows handling of full-duplex data rates up to 560Gbit/s per 16-slot shelf when using a 40 Gbit/s switching fabric. With the 16-slot shelf, capacity can be scaled upwards by adding the necessary amount of blades, RTMs and AMC modules. On the cabinet level, more shelves or even cabinets can be added.

Redundancy principles All the crucial parts of the ATCA Flexi NS - MME have been backed up to ensure the reliability of the system's operations. The various redundancy principles are described in the section below. Redundancy of the functional units Different redundancy techniques are used for backing up different types of functional units. 2N redundancy means that there is always one spare unit available to take over the tasks of a faulty unit. N+1 means that the workload is shared between all devices, and if one malfunctions, the other units are able to carry the full load. N+ means that all units are active and processing traffic in load-sharing mode. The following table shows the redundancy model of each unit:

Overview of AHUB3-A The ATCA hub blade AHUB3-A is the main switch used for internal traffic between nodes in a network element and, by employing its Layer 3 capability, it can also be used for routing traffic to/from external networks. The hub blade provides connections for two types of networks: • •

Base interface (BI) switch for the network element’s internal traffic (for communication between computer nodes) Fabric interface (FI) switch for communicating with external networks as well as for the network element’s internal user data communication (for example, user data transmitted through AMC modules).

In addition, AHUB3-A provides management interfaces towards shelf manager through the base switch, and the hub can also be used for distributing a reference clock signal to other ATCA units (the signal can be either received from an external source or it can be generated locally).

Figure 18

AHUB3-A

The hub blade is a single-slot wide blade equipped in the two hub slots (slots 8-9) in the 16-slot ATCA shelf. Two hub blades are always required in one shelf for redundancy.

System manager The system manager is the central management application in the ATCA system, providing a user interface for accessing hardware-related information, such as configuration data and various logs and measurements. The system manager consists of software running on, for example, a redundant pair of CPU blades. The tasks of the system manager include: • • •

handling FRU state transitions, such as hot swaps and resets storing centralized information on events and alarms in the system storing FRU information

The system manager and the shelf manager are connected through the base interface, and communicate via IPMI commands. The system manager communicates with the shelf manager via IPMI commands encapsulated as remote management control protocol (RMCP) packets. The shelf manager sends events to the system manager as simple network management protocol (SNMP) traps. System manager is not part of the ATCA hardware platform. ATCA hardware platform offers only the hardware, the software platforms offer the software functionality.

Shelf manager The shelf manager controls all blades and other field replaceable units (FRUs) in the shelf through the intelligent platform management interface (IPMI). Each blade in the shelf has an IPM controller (IPMC) connected to the shelf manager’s shelf management controllers (ShMC) through a redundant intelligent platform management bus (IPMB0). AMC modules and rear transition modules contain a module management controller (MMC), which interfaces with the IPMC in the controlling blade. The ShMCs, IPMCs and MMCs together form the intelligent platform management (IPM) subsystem. Fan modules and power entry modules are connected to the shelf manager through a master-only I2C bus.

Blade management IPMC subsystem overview Each blade contains an Intelligent Platform Management Controller (IPMC) subsystem which provides the ability to monitor, query, and log system management events on the blade. The functions of the IPMC subsystem include controlling the blade state, power supplies, and LEDs, monitoring voltages and temperatures, logging events, and maintaining information on the blade. The IPMC subsystem consists of the following components: • • • • •

IPM Controller EEPROM Local voltage and temperature sensors Serial interfaces Power load control

The IPMC subsystem communicates with the shelf manager through the Intelligent Platform Management Bus (IPMB). It also stores a Local System Event Log (SEL) and Sensor Data Records (SDR) which can be used for troubleshooting purposes. In addition, the EEPROM contains a Field Replaceable Unit (FRU) information storage. The user can access the information stored in the IPMC subsystem through the system manager.

12.4.2

Sensor data records (SDR) The IPMC subsystem contains sensors for monitoring the payload power, voltages, or the general health of the field replaceable unit. The power sensors monitor all voltages of the IPMC power supplies. An alarm is raised if one of the values exceeds the allowed range. The temperature sensors monitor the temperature of the board and components, as well as the ambient temperature at the blade's backplane. Sensor data record may also contain information about the state of the FRU hot swap or software upgrade. The user can access the sensor data record through the system manager.

System event log (SEL) The system event log (SEL) stores all IPMI events, such as hot swaps and resets. This information can be used for troubleshooting. The SEL is stored in an EEPROM managed by the IPM controller. The SEL can log 447 entries. When it fills up, the oldest events are deleted. The SEL information is periodically sent to the system manager. The user can read the local SEL through the system manager.

RTM management A rear transition module (RTM) is managed through its front blade. The RTM and the blade are connected by the RTM's zone 3 connector. The front blade’s IPM controller (IPMC) connects to the RTM’s Module Management Controller (MMC) to handle the RTM operation, such as hot swap, LEDs, and sensors. The RTM contains an EEPROM for storing its own FRU information. The RTM also receives its power from the front blade.

FRU information repository All field replaceable units (FRUs) that contain a hardware management controller contain an EEPROM for storing information about the unit itself. This information storage is commonly referred to as a FRU information repository. The repository contains information on the firmware versions, addressing, connectivity, and configuration of the unit. This information can be viewed through the system manager or with shelf manager clia commands. For the shelf alarm display, shelf alarm panel and shelf data module of the 16-slot shelf, only identification information is available, and it is included in the shelf FRU information. Cabinets, PDUs, and cables do not have electronically stored FRU information.

Interconnection domain in the 16-slot shelf

13 Interconnection domain in the 16-slot shelf The interconnection domain connects line interfaces to each other and to the traffic processing entities (computer domains). The interconnection topology from the hub blades to other slots in the shelf is a dual star. The hub blade contains physically separate base interface (BI) and fabric interface (FI) Ethernet switches. Ethernet switches in other ATCA blades segregate the base and fabric interfaces either physically or by means of software. Switch configuration and supervision is handled by unit computers on the blades.

13.1

Base interface (BI) and fabric interface (FI) Base interface The base interface is the main internal communication channel in the system. It is implemented as a Gigabit Ethernet network. Each node slot has a dedicated base interface connection to both hub slots. The hub blade has a dedicated Ethernet switch for the base interface, in accordance with the PICMG 3.0 specification. Fabric interface The fabric interface handles user plane and other external communication in the system. It is implemented as a 10 Gigabit and 40 Gigabit Ethernet network. Each node slot has a dedicated fabric interface connection to both hub slots. The AHU2-X/AHUB3-X hub blades support 10Gb Ethernet and the AHUB4-X hub blades support both 10 Gigabit and 40 Gigabit Ethernet. The hub blade has a dedicated Ethernet switch for the fabric interface. Specifically, the hub uses a 10G Base-KX4 (XAUI) interface, where all four lanes are reserved for 10-gigabit Ethernet transmission in accordance with the PICMG 3.1 specification option 9. The AHUB4-X hub blades also use 40G Base-KR4 interface, individually selectable for each lane.

Embedded software management domain

14 Embedded software management domain The software management domain handles embedded software redundancy and software upgrade. Embedded software redundancy The most critical embedded software images are duplicated. For example, hardware management controller firmware and BIOS are duplicated. The software image and its redundant pair are located in two logically separated areas in non-volatile memory. System manager can select to use either software image via the hardware management controller of the blade or AMC. In the boot phase, the software image checksum is calculated before starting the execution. If the image is corrupt (checksum mismatch), the spare image is taken into use (switchover) and it becomes the active image. Embedded software upgrade The exact upgrade procedure for embedded software may vary depending on the hardware unit; however, the main mechanisms defined in PICMG HPM.1 commonly apply: • • • •

An update software image is first installed in the spare memory bank The FRU is re-booted and the spare bank becomes the active bank If the boot succeeds, the updated image can also be copied to the spare bank If the boot fails, a switchover to the older software image in the spare bank occurs.

All embedded software can be upgraded without removing the FRU from the shelf. In principle, the system manager holds a data repository containing the software images to be uploaded to the FRUs. Depending on the FRU, the software upgrade is controlled via CLI or SNMP. TFTP can be used to transfer the software image to the FRU.
