FAQ
IBM Cloud File Storage for VPC provides secure, persistent, cloud NFSv4.1 file storage. It allows you to create zonal file shares for IBM Cloud Virtual Servers on Virtual Private Cloud, offering flexible customization, smart management, and enterprise-grade resilience.
Your data is secured with encryption-at-rest, encryption-in-transit, and enterprise-grade access controls. You can use IBM-managed encryption keys or your own customer keys for added security.
You can choose the dp2 profile for zonal file shares or the rfs profile for regional file shares (with special access). These profiles define capacity, performance, and data availability characteristics.
You can control access by specifying the access mode: targeted access for specific instances or VPC-wide access. For regional file shares, you use security groups to manage access.
Yes, you can increase the file share size from its original capacity in GB increments up to 32,000 GB. You can also adjust IOPS or bandwidth to meet your performance needs without causing outages.
IBM Cloud File Storage for VPC requires NFS versions v4.1 or higher. NFS v4.1 includes support for advisory byte-range file locking for data consistency.
To mount a file share, you need to create a mount target, which generates an NFS mount path. You can then SSH into your virtual server instance and attach the file share using this mount path.
You pay for only the capacity and performance that you need. Billing is adjusted automatically when you increase capacity or adjust IOPS or bandwidth.
