Shelf Manager Support for PICMG HPM.2 AND HPM.3
Page 1 of 1
A new release of the Pigeon Point Shelf Manager adds support for the PICMG HPM.2 and HPM.3 specifications, complementing corresponding support in the Pigeon Point Board Management Reference (BMR) products, which was delivered in April 2013. Release 3.3.0 now also includes radial IPMB-0 support for the ShMM-700R, the fourth generation of Pigeon Point’s Shelf Management Mezzanine (ShMM) products that are already installed in tens of thousands of ATCA shelves, worldwide.
HPM.2, the LAN-attached IPM Controller specification, was adopted by PICMG in August 2012 and standardizes how xTCA management controllers can attach to an in-shelf LAN. HPM.3, the DHCP-assigned Platform Management Parameters specification, was adopted in November 2012 and covers how the Dynamic Host Configuration Protocol (DHCP) can be used, on an implementation-independent basis, to efficiently assign controller parameters such as network addresses.
The new specifications standardize functionality that was already implemented in many xTCA ecosystem products. Now, ecosystem participants and customers can leverage interoperability among independent implementations of these specifications, which also add advanced features that were not previously available for LAN-attached management controllers. Leveraging and strengthening this interoperability, Polaris Networks’ ATCA Tester compliance test product now includes tests for HPM.2 and HPM.3 requirements.
The HPM.2 emphasis in the 3.3.0 Shelf Manager is on enabling HPM.2 usage by boards and modules in a shelf, especially for diagnostic and maintenance purposes. Key examples of such usage include IPMI messaging trace collection, extended serial over LAN access and higher speed firmware upgrades using the PICMG HPM.1 protocol. In these uses, the emphasis is on external entities, such as HPM.1 upgrade agents or serial over LAN clients, establishing HPM.2 LAN sessions with management controllers.
With the 3.3.0 release, the Pigeon Point Shelf Manager on the ShMM-700R also supports the option for an FPGA-based radial implementation of the main ATCA management bus, IPMB-0. The flexible ShMM-700R radial IPMB-0 architecture allows a range of price/performance choices and is capable of supporting up to 32 separate logical IPMB-0 segments.
