In this presentation, Scott Gnau from Teradata Labs presents: Teradata Intelligent Memory. <blockquote>The introduction of Teradata Intelligent Memory allows our customers to exploit the performance of memory within Teradata Platforms, which extends our leadership position as the best performing data warehouse technology at the most competitive price,” said Scott Gnau, president, Teradata Labs. “Teradata Intelligent Memory technology is built into the data warehouse and customers don’t have to buy a separate appliance. Additionally, Teradata enables its customers to buy and configure the exact amount of in-memory capability needed for critical workloads. It is unnecessary and impractical to keep all data in memory, because all data do not have the same value to justify being placed in expensive memory.” </blockquote>

1. TERADATA INTELLIGENT
MEMORY

2. Trends
• Memory is 3,000 times faster than disk
• Memory per node is increasing
> 96GB -> 256GB ->512GB
• Cost of memory is decreasing
Issues
• Memory still 80x more expensive than disk
• Not all data fits into memory
• Not all data worth 80x premium
Teradata Solution
• Create a new extended memory space
for most frequently accessed data
Exploiting Technology Trends

access to ALL
data for
analysis
A Smarter Approach than In-Memory Databases
Extend multi-temperature data
management to memory

7. • Memory Capacities Growing Exponentially
• Traditional Cache Reaches Diminishing
Returns
• Data is stored compressed and in columns
and rows
• Created extended memory space beyond
cache
• Use it in a new innovative way
