Storage capacity and IOPS - FSx for ONTAP

Storage capacity and IOPS

When you create an FSx for ONTAP file system, you specify the storage capacity of the SSD tier. For each GiB of SSD storage that you provision, Amazon FSx automatically provisions 3 SSD input/output operations per second (IOPS) for the file system, up to a maximum of 160,000 SSD IOPS per file system. You have the option to specify a level of provisioned SSD IOPS above the automatic 3 SSD IOPS per GiB. For more information about the maximum number of SSD IOPS that you can provision for your FSx for ONTAP file system, see Impact of throughput capacity on performance.
