Netezza TwinFin Hardware Configuration
Netezza TwinFin comes in 3 models: TwinFin 3, TwinFin 6 and TwinFin 12; this number indicates number of S-blades or processors. All models come with
- Storage: 1 TB hard drives
- Processor: two CPU, quad core (that is, TwinFin 3 is 3 x 2 CPU with quad core processors).
- Disk storage: Processor-core factor in TB. For instance, for TwinFin 3 it is 24 TB (take above number, 3 x 2 x 4 core, take this in TB; in other words, each core gets a disk).
- Netezza version: 5.0 onwards; 6.0 beta is already out as of beginning for 2010 Q1.
TwinFin is radically different from earlier models. Netezza implemented CPU, memory and storage along with an FPGA on previous models. TwinFin uses S-blades that includes CPU, memory and FPGA (a new term coined by Netezza: database accelerator card = FPGA + memory + IO interface); storage is separated and is located in a storage array.
S-blades and Storage
TwinFin 12 is a full rack containing all components. Top portion is occupied by storage array, followed by two hosts (Linux based hosts, configured for high availability so that if one host fails another takes over), KVM and an array of S-blades. Data between two hosts are replicated and are always synched up so that if one host fails, another can assume that role without any problem.
Disk space for TwinFin 12 is a total of 96 TB; one third of it is only used for storing data, another one third is for disk mirror and the other one third is for spool or temporary space for processing queries. Roughly, 32 TB is available on TwinFin 12 for storage of data.
