This document lists the quotas and system limits that apply to Google Cloud Managed Lustre.
- Quotas specify the amount of a countable, shared resource that you can use. Quotas are defined by Google Cloud services such as Google Cloud Managed Lustre.
- System limits are fixed values that cannot be changed.
Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.
The Cloud Quotas system does the following:
- Monitors your consumption of Google Cloud products and services
- Restricts your consumption of those resources
- Provides a way to request changes to the quota value and automate quota adjustments
In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.
Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.
There are also system limits on Managed Lustre resources. System limits can't be changed.
Limits
System limits
Managed Lustre enforces the following system limits:
| System limit | Value |
|---|---|
| Minimum storage capacity per Managed Lustre instance | 18000 GiB |
| Maximum storage capacity per Managed Lustre instance | 936000 GiB |
| Maximum file size | 0.5 PiB |
| Maximum number of instances per project | 20 |
Quotas
Your initial quota for storage capacity per instance is lower than the system limit. To request additional capacity, complete the Managed Lustre support form.
