Two of a Kind
The latest appliances from Teradata fill a void in the marketplace for cost-effective solutions that handle specific workloads.
Teradata continues its industry-leading innovation in appliances with the unveiling of two new workload-specific models. The Teradata® Integrated Big Data Platform 1700 and the Teradata Data Warehouse Appliance 2750 deliver analytic capabilities that are designed for particular workloads. To find out what makes the appliances unique in the marketplace, Teradata Magazine spoke with Irv Stomackin, Teradata Appliances Program Manager, about new price points, improved technologies and attention-grabbing enhancements.
Can you explain the main differences between the Teradata Integrated Big Data Platform 1700 and the Teradata Data Warehouse Appliance 2750?
Stomackin: Both appliances are enterprise-class Teradata platforms, but each one is designed for a targeted segment of data warehousing workloads. The Integrated Big Data Platform 1700 is the premier platform for applying business analytics to massive amounts of detailed relational data at an affordable cost per data unit. The Data Warehouse Appliance 2750 is the premier platform for customers new to integrated data warehousing, for special-purpose applications and for analytical “sandboxes.”
For the Integrated Big Data Platform 1700, what does “affordable cost per data unit” mean?
Stomackin:This appliance delivers a best-in-class SQL engine at a breakthrough price per terabyte [TB], which is competitive with other big data technologies. It is purpose built to cost-effectively analyze extremely large amounts of detailed data—up to 234 petabytes uncompressed—to gain deep, strategic intelligence. Now customers are able to keep all of their data within the Teradata appliance—with the same format and schema—since there is no need to sample or discard data due to storage limitations. Customers can also choose to cost-effectively keep a second copy of their IDW [integrated data warehouse] for disaster recovery and offload some of its workload during peak periods.
Apache™ Hadoop® can store and analyze large amounts of data. How does the Integrated Big Data Platform 1700 compare?
Stomackin: The appliance enables the Teradata Database for analyzing massive sets of relational data and should be used for offloading colder data or specific workloads from IDWs. The appliance is ideal for organizations that are accustomed to all of the performance, support, features, ease-of-use and powerful analytics that Teradata delivers. Hadoop is more suited for storing raw, multi-structured data, simple cleansing and transformations, and non-relational, non-SQL processing.
Have other improvements been made to the Integrated Big Data Platform 1700?
Stomackin: Yes. It offers BYNET® V5 networking and enhanced processing speed with dual Intel® Xeon® Sandy Bridge 8-core processors running at 2.6 gigabytes [GB]. The new 3TB drives enable a 150 percent increase in customer data space over its predecessor. System availability has been increased with global hot spare drives to complement the optional hot standby nodes, and data is better protected with improved data storage architecture.
What enhancements have been implemented in the Teradata Data Warehouse Appliance 2750?
Stomackin:This appliance introduces the new 12-core Intel Xeon Ivy Bridge CPU to the Teradata workload-specific platform family. Along with Teradata Intelligent Memory and the latest Teradata Database 14.10, it delivers up to three times more system-wide performance improvement out of the box, as compared to the Data Warehouse Appliance 2690. The Teradata Data Warehouse Appliance 2750 supports up to 512GB of memory per node and up to 4TB of memory per cabinet. It uses Teradata Intelligent Memory to provide customers with fast access to their hottest data and to deliver the performance of in-memory in a way that makes sense for data warehousing. And for the highest performance and quickest query response times, the appliance leverages the Teradata Columnar technology.
Additionally, for the first time in the appliance product line, Teradata now offers kits to upgrade the CPU and the memory in the Data Warehouse Appliance 2700 to the levels found in the Teradata Data Warehouse Appliance 2750. The ability to upgrade lengthens the lifespan of the many Data Warehouse Appliance systems that are currently in the field for better investment protection for our customers.
Compared to previous Teradata appliances, what else has changed?
Stomackin:Both appliances support SLES 11 only and come configured with Teradata Integrated Workload Management [IWM]. Previously appliances only included CPU resource management, filters and throttles, but now IWM offers CPU and I/O resource management, flexible classifications, filters and throttles, and tactical and timeshare prioritization and exceptions.
The Integrated Big Data Platform 1700 now uses the larger 42U cabinet, enabling more storage capacity and reducing the expensive data center footprint. To help mitigate concerns with large drive reliability, the appliance is configured with RAID 6 to provide enhanced fault tolerance, and it leverages the Write Back Cache feature for
