CPC7301 Intelligent Shelf Manager

下載PDF

Shelf management ensures maximum service availability in a computing platform by monitoring sensors and predicting failures. The CPC7301 Intelligent Shelf Manager offers a comprehensive management architecture that delivers high availability protection with reliable, redundant and IPMI (Intelligent Platform Management Interface) standards-based management to all the major components in the shelf, including the entire IPnexus™ product family.

The CPC7301 is a 3U, single-slot, Intelligent Shelf Manager (ISM) card for all IPnexus platforms. It provides centralized management and alarming for system power supplies, fan trays, fabric slots and node slots; including IPnexus single board computers and I/O cards. The ISM may be paired with a redundant standby ISM for use in high availability applications. A dedicated ISM-to-ISM link allows redundant ISMs to synchronize management data and polling for failover. The ISM provides comprehensive user and software interfaces via SNMP (Simple Network Management Protocol), APIs (Application Programming Interface), CLI (Command Line Interface), RMCP (Remote Management Control Protocol) and a Web interface. The single slot, 6U, RTM4820 Rear Transition Module (RTM) provides rear panel access to the I/O functions of two redundant CPC7301A ISMs.

Part of the Advanced Managed Platform offering, the CPC7301 provides hot-swap slot control and monitoring of IPMI-based components in the chassis. When thresholds (such as temperature and voltage) are crossed or a failure occurs, the ISM captures these events, stores them in an event log, sends SNMP traps and drives the telco alarm relays and alarm LEDs. User defined scripts and applications allow OEMs to extend functionality directly into the ISM. The ISM can query FRU information (such as serial number, model number, manufacture date, etc.), detect presence of components (such as fan tray, CPU board etc.) and perform health monitoring of each component. In addition, the ISM controls the user-defined power-up sequencing of each slot via radial BD_SEL# signals.

Star Topology

In conjunction with the IPnexus platforms, the CPC7301 provides a point-to-point IPMI connection from the ISM to each individual node or fabric slot, to the power supply subsections and to the fan tray section in the chassis - much like an Ethernet switch in a star topology. The ISM acts as the primary Baseboard Management Controller (BMC) for the entire chassis, blocking any traffic between two points of the star.

This protected architecture has two major benefits:

High Reliability

If any IPMI-based component or subsystem fails and renders its bus inoperable, the ISM isolates it from the rest of the IPMI framework.

High Security

The ISM allows multiple single board computers with BMCs to coexist in the same chassis but not compete as the primary management controller.

Comprehensive Management

The ISM manages up to 21 slots, which may be any combination of node slots and fabric switch slots. In addition, it manages up to eight power supplies, up to four fan trays and up to two redundant ISMs (itself and the standby ISM). It can also access chassis sensors and a comprehensive list of management information and configuration options provided by switched fabric components.

High Availability

The Intelligent Shelf Manager provides the ability to operate in redundant mode, where one ISM is active and the other is in standby mode. In the event of a failure on the active ISM, the standby ISM takes over control of the chassis. A dedicated watchdog timer on each ISM monitors the software. In the event of a software failure on the active ISM, the watchdog will initiate failover to the standby ISM and reset the unstable ISM.

The configuration information, event log and other state information of the active ISM is continuously synchronized with the standby ISM. This synchronization can be performed via Ethernet switches in or out of the platform, an Ethernet cable via front or rear panel or via a dedicated, internal ISM-to-ISM Ethernet link to eliminate dependence on Ethernet switches and external cabling.

The firmware on the ISMs can be updated remotely via the network in a secure, fail-safe operation. This can be sequenced so that one ISM is active while the other is being updated.

The ISMs are hot-swap capable for "always on" service and to reduce MTTR (Mean Time To Repair).

Front Panel Input/Output

The Intelligent Shelf Manager’s front panel supports the following I/O (see the RTM4820 datasheet for details on the Input/Output features for the ISM Rear Transition Module):

• Out-of-band 10/100 Ethernet port provides access to SNMP, the Command Line Interface (via Telnet or SHH), RMCP, FTP and the Web interface. It is also used for sending network alerts
  • In-band 10/100 Ethernet port via packet-switched backplane is also supported
  • Green link LED and amber activity LED
• µDB15-pin Telco alarm interface
  • Dry contact relays indicate critical, major and minor events and generate a continuous output until the alarm cut-off button is pressed or it is turned off via software
  • Dry contact relay indicates power fail
  • Two optically isolated inputs allow clearing of major and minor alarms
  • The relays and inputs are abstracted for future user-defined options
• RJ-45 COM port provides access to the Command Line Interface
• Minor, major and critical LEDs: three independent LEDs
• Hot-swap LED indicates ready to be hot removed
• Status LED indicates Active/Fault status

NexusWare™ ISM NexusWare ISM is a development environment that allows customers to add their own value and functionality to the CPC7301 Intelligent Shelf Manager (ISM). It leverages the flexible and scalable architecture of the ISM, allowing customization of Linux kernel 2.4.18 and ISM settings, addition of third-party applications and modification of ISM management behavior.
