Pure FlashBlade Replication Base Setup
This video is part one of a video series where WWT resources will walk through the base network configuration and array connection establishment for two FlashBlade systems in the Advanced Technology Center (ATC).
We are excited to have worked with Pure Storage to upgrade our FlashBlade systems to Purity //FB 3.0. This software release has opened up important new features that our joint customers have been waiting for. The most significant feature in this release is File and Object Replication.
File replication is configured and managed using the Purity//FB GUI, CLI, and REST API. Note the following:
- File systems created on arrays running a pre-Purity//FB 3.0.0 version are not eligible for replication.
- Only snapshots created as part of the replication process are transferred.
- Encryption over the wire is not yet supported.
Note that when connecting arrays:
- The management IP address required during configuration cannot be a loopback IP address.
- An IP address must be specified for the replication address; specifying the hostname/FQDN is not allowed.
S3 targets that are not AWS are not supported. Object replication is configured and managed using the Purity//FB GUI, CLI, and REST API. Note the following:
- Objects that were created before the creation of the object replica link are not eligible for replication.
- Object versioning on the target bucket must be enabled.
Note that when connecting arrays, the management IP address required during configuration cannot be a loopback IP address. Cascading replication topology is not supported.
Restoring a file system from a snapshot will overwrite the contents of the file system with data from the snapshot, and may disrupt workloads running against the file system. Stopping all I/O, including reads, writes and all metadata operations against the file system is recommended.
Note that when file system is rolled back to an older snapshot, the quota limits remain unchanged (i.e. the quota limits are not part of the snapshot).
File system rollback is available for snapshots created on a FlashBlade array running Purity//FB 3.0.0 or later.
