1.2 Tib/s Storage Spaces Direct: Mellanox, HPE and Micron Show NextGen All-Flash Data Center

Mellanox, Hewlett Packard Enterprise (HPe) and Micron recently collaborated to redefine “fast” – as in fast networking, fast throughput, fast data.  How fast was fast? 1.2Tib/second on a 12-node cluster fast!

More than the sum of the parts

To reach this performance level, the teams selected each component carefully:

  • Windows Server 2016 Datacenter Storage Spaces Direct
  • HPE Proliant DL380 Gen9 Servers
  • Mellanox ConnectX-4 100 Gb/s RoCE adapters
  • Mellanox Spectrum Ethernet Switches and LinkX cables
  • Micron 9100 MAX 2.4TB NVMe SSDs

And the result is more than the sum of the parts: extreme performance and extreme scale.  Take a look at the numbers:

The Servers Still Had Plenty of Headroom!

The servers were barely breathing hard during this testing, leaving plenty of CPU resources for other tasks.  With 1.2Tb/sec of sustained storage traffic running across the cluster, each node in the cluster consumed only 25% of available CPU capacity leaving plenty of power to perform additional computer tasks. 

Results, results, results!

This joint Windows Server 2016 demonstration simulates application and user workloads using DiskSpd and VM Fleet* across a 12 node cluster using Storage Spaces Direct, Hyper-V, Windows Clustering, local high performance NVMe SSDs and 100GbE RoCE - eliminating complex and costly external shared storage requirements from Windows Server 2016 SDS solutions. The demonstration used DiskSpd to generate 512KiB read requests from each of the 336 Windows Server 2016 Server Core VMs in the cluster, controlled by VM Fleet.
