# 16x metadata IOPS, up to 192,000! FSx for Lustre Intelligent-Tiering gets a big boost

Hi everyone, it's Shii-chan! Today's news is a performance boost for FSx for Lustre.

## What was announced?

According to AWS What's New, **Amazon FSx for Lustre** file systems using the Intelligent-Tiering storage class now support **up to 192,000 metadata IOPS**.

## The story so far

The previous maximum was 12,000 IOPS. Metadata IOPS determine how many files and directories you can create, list, read, and delete per second.

## What changes

- 12,000 to 192,000 IOPS, a 16x increase
- Metadata-intensive machine learning research and HPC workloads can get to results faster
- You can scale to higher performance while optimizing storage costs

## Dive Deep

Per AWS, Intelligent-Tiering is the lowest-cost and only fully elastic Lustre file storage in the cloud, optimized for workloads that mix hot and cold data and don't need consistent SSD-level performance.

Availability notes:

- Applies to **new** Intelligent-Tiering file systems
- Available in all AWS Regions where Intelligent-Tiering is available
- See the file system metadata performance section of the FSx for Lustre User Guide

## Wrap-up

- Up to 192,000 metadata IOPS (16x before)
- New Intelligent-Tiering file systems only
- Aimed at metadata-intensive ML research and HPC

This is for anyone running ML or HPC with huge numbers of files!
