Coexistence Systems
Coexistence
• In a 64 bit Linux and Windows environment,
coexistence across multiple generations is once
again supported with the 5600 platform
> 5600H model provides balance for coexistence back to 5500H
> 5600C model provides balance for coexistence back to 5500C
–
Leverages flexibility of larger memory with Linux

Appliance Strategy
• Nodes/Storage in same rack and no UPS
> ADW (5xxx) have discrete node and storage racks with UPS
• Common parts & similar packaging
> Common disk array controller
– Model differentiation with disk drive configuration and types
> Same node types
> Storage and nodes combined in a single cabinet
– Common chassis locations
> Common wiring harnesses

Next Generation BYNET
BYNET™
Optimized for Teradata ADW Performance
BYNET
• Bynet has linearly scalable bandwidth
• BYNET Low Latency Interface (BLLI) - “lite” communication protocol
• Teradata exploits unique BYNET features:
•
> broadcast message support, row merge support, multi-fabric message traffic
shaping, hardware guaranteed message delivery (including broadcast)
Proven High-Availability
> Each fabric is fault tolerant (multiple paths, redundant power & cooling)
> Two independent fabrics (no single point of failure)
Multiple Simultaneous
Point-to-Point Messaging
Node

The Teradata
Optimizer chooses
between Point-to-Point
and Broadcast Messaging
to select the most

So What Is An SSD Disk?
Traditional Hard Disk
Solid State Disk
• Solid-State Disk (SSD) Data storage device
> Emulates a hard disk drive (HDD)
> Same electrical and physical package as a Hard Drive
> Contains arrays of flash memory devices
