Contributors netapp-barbe

ONTAP Select 9.4 performance with premium HA direct-attached SSD storage.

Reference platform

ONTAP Select 9.4 (Premium) hardware (per node):

  • Cisco UCS C240 M4S2:

    • Intel Xeon CPU E5-2697 at 2.60GHz

    • 2 x sockets; 14 x CPUs per socket

    • 56 x logical CPUs (HT enabled)

    • 256GB RAM

    • VMware ESXi 6.5

    • Drives per host: 24 X371A NetApp 960GB SSD

Client hardware:

  • 4 x NFSv3 IBM 3550m4 clients

Configuration information:

  • 1,500 MTU for data path between clients and Select cluster

  • No storage efficiency features in use (compression, deduplication, Snapshot copies, SnapMirror, and so on)

The following table lists the throughput measured against read/write workloads on an HA pair of ONTAP Select Premium nodes. Performance measurements were taken using the SIO load-generating tool.
