# Features

<PFSFeaturesNav />

## Feature Overview

### 1. High-Performance Parallel I/O
PFS is optimized for maximum throughput in parallel workloads, delivering superior performance for HPC (High-Performance Computing) applications.
*   **Benefit:** Handle intensive I/O operations with minimal latency and maximum bandwidth.

### 2. Multi-Node Concurrent Access
Multiple compute instances can access the same PFS simultaneously with full read/write capabilities.
*   **Flexibility:** Share data across distributed HPC (High-Performance Computing) workloads without performance degradation.

### 3. Custom Mount Paths
Specify your preferred mount location when attaching PFS to Instances.
*   **Integration:** Seamlessly integrate with your existing application directory structure.

### 4. Scalable Storage
Resize your PFS storage capacity as your workload demands grow.
*   **Cost-Effective:** Start with what you need and scale to meet increasing requirements.

## Managing Your PFS

### Actions Overview

The **Actions** button provides management options for each PFS:
*   **Increase PFS Size** - Expand the storage capacity of the existing file system
*   **Delete File-System** - Permanently remove the file system and all stored data


### Resizing PFS

The PFS resize feature allows you to increase storage capacity to meet growing performance demands.

#### How to Resize

:::warning Important
Before resizing a PFS, you must **UNMOUNT** it from all attached Instances to prevent data corruption.
:::

1. **Prepare for Resize:**
   *   Unmount the PFS from all attached compute instances
   *   Ensure no active processes are accessing the file system
   *   Backup important data as a precaution

2. **Access Resize Option:**
   *   Click the **Actions** button for your PFS
   *   Select **Increase PFS Size** from the dropdown



3. **Select New Size:**
   *   Use the slider or input field to select your desired size
   *   Ensure the new size is larger than the current size
   *   Review the pricing changes
   *   Click **Update** to proceed


4. **Remount After Resize:**
   *   Once resize completes, remount the PFS to your Instances
   *   Verify the new capacity is reflected in your system


### Deleting PFS

Permanently remove a Parallel File-System when it's no longer needed.

:::danger Data Loss Warning
Deleting a PFS will **permanently remove all data** stored on it. This action cannot be undone. Ensure you have backups of any important data before proceeding.
:::

#### How to Delete

1. **Prepare for Deletion:**
   *   Unmount the PFS from all attached Instances
   *   Backup any data you want to preserve
   *   Verify no active workloads depend on this storage

2. **Access Delete Option:**
   *   Click the **Actions** button for your PFS
   *   Select **Delete File-System** from the dropdown



3. **Confirm Deletion:**
   *   A confirmation dialog will appear
   *   Review the details and understand the implications
   *   Check the acknowledgment checkbox
   *   Click **Delete** to permanently remove the PFS


## Monitoring Your PFS

### Attached Services

View which compute instances are currently using your PFS by clicking the **Services** tab.

*   **Instance Details:** See the names of attached Instances
*   **Mount Information:** View the mount paths for each instance
*   **Management:** Easily identify which workloads depend on this storage


## Best Practices

### Performance Optimization

*   **Parallel Access Patterns:** Design applications to leverage parallel I/O capabilities
*   **Optimal Block Sizes:** Use larger block sizes for sequential operations
*   **Network Configuration:** Ensure high-bandwidth network connectivity

### Cost Management

*   **Right-Size Storage:** Provision capacity based on actual performance needs
*   **Monitor Usage:** Track utilization to optimize storage allocation
*   **Clean Up Unused Data:** Regularly remove temporary files and old datasets

### Data Safety

*   **Regular Backups:** Implement automated backup strategies for critical data
*   **Pre-Resize Backups:** Always backup before major resize operations
*   **Unmount Protocol:** Follow proper unmount procedures before resize or delete
*   **Access Control:** Limit PFS access to only the Instances that require it
