Test Notes for Big Data Workloads

Scalability Tests were performed on a 9 node cluster of bare metal nodes.

  • CPU - Single socket per server with Ampere Altra N1 processor with 80 cores @3.0GHz
  • Memory - Samsung DDR4 512GB DRAM 3200 MHz
  • Storage - 4 Micron 7300 NVME Drives each with 3.5 TB storage space
  • Network Cards - Mellanox CX-6, 2 x 100Gb/s with a bonded configuration

Terasort Hadoop and Spark tests were done on Ampere Altra and x86 VM's with the following configurations.
  • Intel - Skylake 2000 GHz
  • AMD - Rome 2249 MHz
  • AMD - Milan 2449 MHz
  • Ampere - Altra processors 3000 MHz
  • vCPU's - 16 ARM Cores or 16 x86 threads.
  • Memory - 64 GB
  • Storage - 1TB storage with 1000 MB/sec read/write performance

Note: TPC-DS tests were done on Intel Ice Lake processors(Graph 2).
