Teradata launches hybrid data-warehouse appliance

Teradata on Monday launched a data warehouse appliance that puts information tiering on autopilot as it is shuttled between solid-state and hard-disk drives.

The appliance, the Active EDW 6680, comes in four flavours that depend on the mix of SSD storage involved. Active data that needs to be accessed in real-time resides on SSD, which can be pricey, while information for archives resides on cheaper traditional drives.

For instance, sensor data may reside on SSD while less sensitive information resides on hard-disk drives. Teradata's system evaluates data and puts it in SSD or hard disk based on its characteristics.

Teradata's 6680 appliance is designed to migrate data between drive types to bolster performance. The company also rolled out an Active EDW 6650 appliance that uses hard disk drives and can be upgraded to solid state later.
