1 - Overview

Service Overview

File Storage enables servers connected via a network to easily store and share data, making it a storage solution suitable for application environments that use multiple servers.
You can choose the disk type according to the required performance level, and it will automatically expand or shrink based on the user’s data volume without any capacity limits.

Features

• Free volume usage: The volume capacity automatically expands or contracts based on data creation and deletion without any user configuration. There is no cost for creating the volume; only usage fees for the stored data capacity are incurred.
• Various Disk Types Available: Users can select a disk type based on their usage purpose. They can use HDDs that store large amounts of data cost‑effectively, SSDs that provide reduced response times and high IOPS performance, and high‑performance SSDs.
• Snapshot Backup: The image snapshot feature enables recovery of modified or deleted data, and when performing disk backup, snapshots can be stored in a location different from the original. Users select a snapshot created at the desired point in time from the list to perform the recovery.
• Replication: Creates an identical replica volume at a different location, and users can set the data replication interval. If the original volume becomes unavailable due to failures or disasters, service can be provided through the replica volume.

Provided features

File Storage provides the following features.

• Volume Name: Users can set a name for each volume.
• Disk type: You can select a disk type based on the user’s performance requirements.
  • HDD: Standard volume
  • SSD: high‑performance general volume
  • High‑Performance SSD: Performance‑optimized volume that can be attached to a Multi-node GPU Cluster

  • NFS: Primarily used on Linux operating systems
  • CIFS: Primarily used on Windows operating systems
• Flexible Volume Usage: Provides flexible volume sizing based on the amount of stored data without requiring user capacity settings.
• Connected Resources: can be connected and used from Virtual Server, Bare Metal Server, and Multi-node GPU Cluster.
• Encryption: Regardless of disk type, all volumes are encrypted with the XTS-AES-256 algorithm.
• Snapshot: The image snapshot feature allows immediate or scheduled snapshot creation.
  • Retention Count: The number of snapshots retained that are automatically created by the schedule
  • Schedule: Snapshot auto-creation interval
  • Recovery: restore the original volume to the latest snapshot, or select a snapshot at a specific point in time to create a recovery volume
• Replication: It replicates the volume to another location, and the user can set the replication schedule.
• Disk Backup: You can store snapshots on a backup-dedicated HDD storage and select the backup location.
• VPC Endpoint connection: File Storage can be used via a Private Network connection from an external network.
• Monitoring: usage, IOPS, Throughput, and other monitoring data can be viewed through the Cloud Monitoring service.
• ServiceWatch Service Integration: You can monitor data using the ServiceWatch service.

Component

You can create a volume by selecting the disk type and protocol according to the user’s service environment and performance requirements.
When using the snapshot feature, you can restore data to the desired point in time.

Volume

Volume(Volume) is the basic creation unit of the File Storage service and is used as data storage space. Users select a name, disk type, and protocol (CIFS/NFS) to create a volume, then connect it to one or more Server for use.
The volume name generation rules are as follows.

• It must start with a lowercase English letter and can be set to 3~21 characters using lowercase letters, numbers, and special characters (_).

Snapshot

Snapshot is an image backup taken at a specific point in time. Using the image snapshot feature, you can recover changed or deleted data or store snapshots in a location different from the original when performing disk backups. Users select the snapshot created at the desired point in time from the snapshot list to perform a recovery.
The following are considerations when using snapshots.

Preceding Service

This is a list of services that must be pre-configured before creating the service. Refer to the guide provided for each service for details and prepare in advance.

1.1 - Monitoring Metrics

File Storage Monitoring Metrics

The table below shows the monitoring metrics for File Storage that can be viewed in Cloud Monitoring. For detailed usage of Cloud Monitoring, refer to the Cloud Monitoring guide.

1.2 - ServiceWatch Metrics

File Storage sends metrics to ServiceWatch. The metrics provided by default monitoring are data collected at 1‑minute intervals.

Basic Metrics

The following are the basic metrics for the File Storage namespace.

The indicators whose names are displayed in bold below are the indicators selected as major metrics among the basic metrics provided by File Storage. Key metrics are used to configure service dashboards that are automatically generated for each service in ServiceWatch.

Each metric indicates, via the user guide, which statistical value is meaningful when viewing that metric, and among the meaningful statistics, the values shown in bold are the primary statistics. In the service dashboard, you can view key metrics using these primary statistical values.
