Accessing Storage Configuration Settings
You’ll see the storage configuration page immediately after creating any storage option.
You can also access configuration settings from the Storage tab. Click the name of any existing storage to configure it.
About the Storage Configuration Page
When you navigate to the storage configuration page, there are five tabs for customization.
Sessions
By default, you’ll see the Sessions tab when you navigate to storage settings. This tab shows your previous sessions for using the storage as well as provision and deletion logs.
For persistent storage options, you can see the creation and deletion logs in this tab. All logs for current and previous sessions will be displayed. If a persistent storage option is active, you’ll see all the clusters that the storage is attached to.
Ephemeral storage options do not have a Sessions page. Instead, you can see their creation logs by navigating to Resources > ResourceName > Sessions > Logs > Storages.
For more information about persistent and ephemeral storage, please see About Storage Types.
Definition
Here, you can adjust the configuration parameters of your storage. For more information, see General Settings below.
JSON
This tab shows the code version of your storage configuration settings. Here, you can manually adjust the parameters seen in the Definition tab.
Properties
This tab shows the name that you entered when the storage was created. Here, you can change the name and upload a new thumbnail for the cluster.
Sharing
This tab lets you control storage sharing options for users in your organization who are assigned to the same group.
For more information, please see Sharing Storage.
General Settings
Storage options have these settings in the Definition tab of the configuration page.
Cloud Infrastructure
Use this dropdown menu to choose your infrastructure, which determines which region your storage will be created in.
Group
Use this dropdown menu to select the group name that your organization uses to allocate costs. This menu is especially important if your organization uses multiple groups.
If you’re not sure which group to select, you can contact us or your organization’s PW platform administrator.
Lustre Options: AWS FSx for Lustre
The configuration parameters below are exclusive to AWS FSx for Lustre.
Availability Zone
Use this dropdown menu to select the availability zone that your infrastructure will be deployed in. An availability zone refers to an isolated location inside a region.
We recommend that your storage availability zone matches the availability zone of the cluster you’re pairing the storage with.
Storage Capacity (GB)
Use this field to enter the total capacity of your storage. This field is set to 1200 by default. 1200 is the minimum amount of storage and must be increased in increments of 2400.
Please note that altering the storage size will affect your estimated hourly cost.
Filesystem Deployment
Use this dropdown menu to select which type of filesystem your storage will be deployed as. Currently, the options are scratch and persistent.
Scratch filesystems are meant for shorter-term workloads. They provide a higher throughput per TiB of storage capacity. If a scratch filesystem fails, your data is not replicated.
Persistent filesystems are meant for long-term workloads. If this filesystem fails, your data will automatically replicate in the same Availability Zone.
Filesystem Compression
Use this dropdown menu to select whether your filesystem will be compressed. Currently, the options are LZ4 and NONE.
LZ4 compresses data when writing to Lustre. When reading from Lustre, LZ4 decompresses data while minimally impacting performance. Using LZ4 can improve read and write performance as well as reduce storage capacity.
S3 Import Path (Optional)
Use this field to enter an S3 bucket path to import data from. The format for this field is s3://BucketName.
S3 Export Path (Optional)
Use this field to enter an S3 bucket path to export data to. The format for this field is s3://BucketName.
