Together, StackIQ Enterprise Data and Cisco Unified Computing System
™ (Cisco UCS
®) deliver a fully automated big data infrastructure solution for the enterprise that automates server and cluster configuration and deployment after the solution has been set up.
Cisco UCS and StackIQ Enterprise Data work better together to create manageable clustered infrastructure in the data center.
The combination of StackIQ Enterprise Data management software and Cisco UCS provides a powerful big data infrastructure solution for enterprise data center environments. Each has its own strengths, and when combined they provide exceptional capability for enterprise-class clustered infrastructure. Cisco UCS is an excellent hardware infrastructure solution, providing flexible network computing and storage. StackIQ Enterprise Data software provides a unique, complete cluster management solution that supplements Cisco UCS Manager. StackIQ Enterprise Data integrates transparent with Cisco UCS to install, configure, and deploy all the software in the Cisco UCS cluster.
The Cisco UCS open XML API provides automated, real-time discovery of system hardware configuration information to StackIQ Enterprise Data. That information is used to provision the cluster and automate ongoing hardware change management.
The Cisco and StackIQ solution delivers transparent management capability for the bare-metal machines, the network, the operating system, and the big data software. It addresses the challenge of big data deployments in the enterprise by making clusters reliable and repeatable.
Enterprise Use Cases
The most common application of clustered infrastructure in the enterprise data center is big data. Today these clusters typically run one of the popular Apache Hadoop distributions or a NoSQL distribution. The StackIQ solution for Cisco UCS supports multiple Hadoop and NoSQL distributions from industry leaders, so customers can choose the big data software that best meets their needs.
Using Hadoop, organizations can move large volumes of complex and relational data into a single repository in which raw data is always available. With its low-cost commodity servers and storage repositories, Hadoop enables this data to be affordably stored and retrieved for a wide variety of analytic applications that can help organizations increase revenue by extracting value such as strategic insights, solutions to challenges, and ideas for new products and services. By dividing big data into multiple parts, Hadoop allows the simultaneous processing and analysis of each part on servers throughout the cluster, greatly increasing the efficiency of queries and reducing response time. The use cases for Hadoop are many and varied, including public health, stock and commodities trading, sales and marketing, product development, and scientific research. For the business enterprise, Hadoop use cases include:
• Data processing: Hadoop allows IT departments to extract, transform, and load (ETL) data from source systems and to transfer data stored in Hadoop to and from a database management system for the performance of advanced analytics. Hadoop is also used for the batch processing of large quantities of unstructured and semistructured data.
• Network management: Hadoop can be used to capture, analyze, and display data collected from servers, storage devices, and other IT hardware to allow administrators to monitor network activity and diagnose bottlenecks and other issues.
• Retail fraud: By monitoring, modeling, and analyzing high volumes of data from transactions and extracting features and patterns, retailers can help prevent credit card account fraud.
• Recommendation engine: Web companies can use Hadoop to match and recommend users to one another or to products and services based on analysis of user profiles and behavioral data.
• Opinion mining: Used in conjunction with Hadoop, advanced text analytics tools analyze the unstructured text of social media and social networking posts, including Tweets and Facebook posts, to determine user sentiment related to particular companies, brands, or products; the focus of this analysis can range from the macro level to the individual user.
• Financial risk modeling: Financial firms, banks, and other companies use Hadoop and data warehouses for the analysis of large volumes of transactional data to determine risk and exposure of financial assets, prepare for potential "what-if" scenarios based on simulated market behavior, and rate potential clients for risk.
• Marketing campaign analysis: Marketing departments across industries have long used technology to monitor and determine the effectiveness of marketing campaigns. Big data allows marketing teams to incorporate higher volumes of increasingly detailed data, such as click-stream data and call detail records, to increase the accuracy of analysis.
• Customer influencer analysis: Social networking data can be mined to determine which customers have the most influence over others within social networks, to help enterprises determine which customers are most important and influential.
• Customer experience analysis: Hadoop can be used to integrate data from previously siloed customer interaction channels (for example, online chat, blogs, and call centers) to gain a complete view of the customer experience. This view enables enterprises to understand the impact that one customer interaction channel has on another so that enterprises can optimize the entire customer lifecycle experience.
• Research and development: Enterprises such as pharmaceutical manufacturers use Hadoop to comb through enormous volumes of text-based research and other historical data to assist in the development of new products.
• Multi-use clusters: Enterprise data centers need to maintain agility within the big data infrastructure to meet rapidly changing requirements from the businesses they support. By implementing a dynamic, flexible cluster infrastructure, organizations can accommodate separate instances of Hadoop, NoSQL databases, and other evolving big data applications simultaneously.
StackIQ Enterprise Data and Cisco UCS: Excellent Big Data Cluster Solution
Organizations of all types are deploying Hadoop and NoSQL solutions to gain a competitive advantage. There is now a range of hardware and software solutions to choose from, and they are being deployed in data centers everywhere. However, these solutions all have something in common: they lack comprehensive management capabilities. Some vendors offer no management, and others offer partial solutions. Today's enterprise data center operations require a complete solution to operate effectively. StackIQ Enterprise Data combined with Cisco UCS native integrated hardware management provides an integrated solution that comes with everything needed to automate the deployment and management of Hadoop and NoSQL clusters-from bare metal all the way to a working system.
Some solutions assume that you are starting with a cluster that has already been provisioned with an operating system, and that each server was properly configured to work on the network. StackIQ takes a different approach. It assumes that there is nothing on the servers after Cisco UCS setup is complete. The StackIQ provisioning tool automatically polls Cisco UCS to synchronize its host database by using the Cisco UCS XML open API, and it installs all the software and configures all the services. Starting with bare metal (empty servers), the StackIQ Enterprise Data manager installs the operating system, libraries, and applications software such as Hadoop. It also configures the network, firewall, disks, and application services, such as MapReduce and Hadoop Distributed File System (HDFS). After this process is complete, each server has the correct software installed on it and is configured with the services it needs to perform its role in the cluster. Table 1 summarizes the process.
Table 1. Three-Step Provisioning Process
Use Cisco UCS Manager to configure the hardware.
Install the StackIQ Enterprise Data management node.
Power on back-end nodes and let the cluster manager install the software on them automatically using the information that StackIQ obtained from the Cisco UCS open XML API.
Apart from the need to select the options to install and enter cluster-specific information in the cluster manager, the process is fully automated, freeing the administrator to perform other tasks.
StackIQ Enterprise Data brings enterprise-class management to Hadoop and other big data applications. It was designed from the foundation to deploy and manage large-scale cluster infrastructure. It combines StackIQ's industry-leading cluster management solution with Hadoop management software, providing everything you need to install, configure, deploy, and manage your cluster from bare metal. StackIQ Enterprise Data makes it easier than ever to build a robust, production-class, big data cluster that can reside in any enterprise data center.
Maintaining the Cluster
After a cluster becomes operational, it will undergo changes. No matter how well planned its deployment was, it will need to be expanded, changes will need to be made, and components will fail. The StackIQ Enterprise Data manager handles all these tasks while maintaining a consistent setup across the cluster. When the cluster is expanded, StackIQ Enterprise Data discovers the new nodes and installs them. To make changes, the administrator adds packages to the distribution and installs the target nodes. The cluster deals with failures by detecting when replacement hardware is available and automatically setting it up with the desired configuration.
Cisco UCS and StackIQ Enterprise Data work together to keep the cluster healthy. Cisco UCS tells the StackIQ Enterprise Data manager when new servers are available, and the StackIQ manager adds them to its database automatically. This approach helps ensure that a consistent, reliable description of the cluster is available at all times. After the server is racked and cabled, the StackIQ Enterprise Data manager detects it and installs the correct software automatically on first boot. The result is a fully automated data center that is easier and cheaper to maintain. Here is an example of system discovery from the command line:
# rocks list ucs host
HOST APPLIANCE STATUS MAC
compute-1-1: compute online 00:25:B5:00:00:5F
compute-1-2: compute online 00:25:B5:00:00:8F
compute-1-3: compute online 00:25:B5:00:00:9F
compute-1-4: compute online 00:25:B5:00:00:6F
compute-1-5: compute online 00:25:B5:00:00:7F
compute-1-6: compute online 00:25:B5:00:00:4F
The appliance type is automatically determined by making an API call to Cisco UCS Manager. The MAC address is the hardware address of the network interface card (NIC) that StackIQ will use as the installation and management network. This is all the information required for StackIQ to begin a bare-metal installation.
• Reduced time to production: Choose the software you want, set critical parameters, and then sit back and let the parallel StackIQ Avalanche installer build your Hadoop cluster right from bare metal. There is no faster way to go from pallet to production.
• Ease of operation: The StackIQ management software for Hadoop provides all the tools you need to keep the cluster healthy and operating efficiently. Competing products do not integrate Hadoop management and cluster configuration and deployment. StackIQ Enterprise Data handles your complete cluster environment from a single pane, providing users with more uptime, efficiency, and performance.
• Extensibility: Modular architecture lets you customize your cluster to meet your particular needs. The platform allows the management of any application in your big data environment through the Open Source Rocks framework. A wide variety of software components are readily available, or you can build your own.
• Reduced time to scale: When you want to scale out your cluster, StackIQ Enterprise Data makes it easy. Because the deployment and management engines were designed for scale, expanding your cluster or creating new clusters at other locations is straightforward. You have no scripts to edit and no configuration guesswork.
• Choice: Choose your favorite distribution from Hortonworks, MapR, Cloudera, or Apache Hadoop, and more.
