Know-how update vol.1


The Intelligent Platform Management Interface (IPMI) is a set of computer interface specifications for an autonomous computer subsystem that provides management and monitoring capabilities independently of the host system’s CPU, firmware (BIOSor UEFI) and operating system. IPMI defines a set of interfaces used by system administrators for out-of-band management of computer systems and monitoring of their operation. For example, IPMI provides a way to manage a computer that may be powered off or otherwise unresponsive by using a network connection to the hardware rather than to an operating system or login shell.


In computing, Puppet is an open-source configuration management tool. It runs on many Unix-like systems as well as on Microsoft Windows, and includes its own declarative language to describe system configuration.

Redfish standard

Scalability in today’s data center is increasingly achieved with horizontal, scale-out solutions, which often include large quantities of simple servers. The usage model of scale-out hardware is drastically different than that of traditional enterprise platforms, and requires a new approach to management.

Designed to meet the expectations of end users for simple and secure management of modern scalable platform hardware, DMTF’s Redfish™ is an open industry standard specification and schema that specifies a RESTful interface and utilizes JSON and OData to help customers integrate solutions within their existing tool chains. An aggressive development schedule is quickly advancing Redfish toward its goal of addressing all the components in the data center with a consistent API.

DMTF welcomes extensions to Redfish and works with its Alliance Partners and OEMs to leverage and expand Redfish. For example, the Storage Networking Industry Association (SNIA) is developing Swordfish, which builds upon Redfish’s local storage management capabilities to address enterprise storage services.

Mirantis Open Stack

Small and medium scale cloud operators can utilize capabilities in Fuel to scale the cloud up/ down, selectively make changes to their configuration (e.g., changing network DHCP address ranges) and deploy new functionality to an existing cloud (e.g., adding plugins like StackLight for monitoring or Murano for a self-service application orchestration and catalog). Customers operating large-scale infrastructure using configuration management tools can now export Fuel configuration values into existing configuration management tools. This enables lifecycle management of a large cloud by using a combination of OpenStack Fuel and existing tools.

NetFlow Analyzer

Cisco NetFlow is a Cisco developed flow technology that allows bandwidth monitoring of a network. NetFlow Analyzer is a software that uses Cisco NetFlow to monitor bandwidth and runs in windows and linux. Cisco routers/switching devices export NetFlow as UDP packets. Cisco NetFlow is one of the flows, among other flows, that is used to monitor bandwidth in the network. These Cisco NetFlow packets can be analyzed using NetFlow Analyzer, to monitor bandwidth, to gather information on the top talkers, applications and many other features. Network traffic analysis is one of the uses of NetFlow Analyzer. NetFlow Analyzer delivers easy-to-understand reports on in-depth traffic analysis and network bandwidth monitoring.

Open Switch

Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license.  It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, IPFIX, RSPAN, CLI, LACP, 802.1ag).  In addition, it is designed to support distribution across multiple physical servers similar to VMware’s vNetwork distributed vswitch or Cisco’s Nexus 1000V.

EMC VPLEX is a virtual computer data storage product introduced by EMC Corporation in May 2010. VPLEXimplements a distributed “virtualization” layer within and across geographically disparate Fibre Channel storage area networks and data centers.
