IBM Storage FlashSystems v8.7.3.0: Non-disruptive Storage Partition Migration

Introduction
IBM Storage FlashSystem recently just announced new version of the product v8.7.3.0, Introducing management the storage at workload level with dedicated storage partitions. Storage partition is a set of objects such as volume, volumegroups, hosts, hostmappings in the system. Typically, Storage Partition is designed such a way that it can be assigned to specific workload. The best part of this is user can manage partition at common user interface with simple one clicks operation.
This further enable the flexibility of easy non-disruptive Storage Partition Migration to significantly simplify data transfers across different storage controller, enhancing the prior experience of guided steps. This blog explores ability to non-disruptively migrate Storage Partition and provide high availability during storage and workload management.

Understanding Storage Partition Migration
With Storage partition feature IBM Storage Virtualize can now help storage admin to execute non-disruptive storage partition migration for different between systems in given network. This function allows data mobility at the Storage Partition, granularity across multiple flash systems without any application downtime.

Single Click Storage Partition Migration
The version of the product enhanced Storage Partition Migration as

• Easy to use One-click administration: A flawless transition and non-disruptive migration are guaranteed by well-planned stages.
• Automatic data copy: All associated objects and mappings are created as part of the storage partition migration procedure, which also guarantees data copy synchronization between the systems.
• Automatic host path switch: partition migration guarantees that hosts in storage partitions with automatic storage rescan capabilities have accurately identified various pathways to the storage and that application I/O are served from the storage partition migrated system.
• Automatic source copy deletion: After data synchronisation the source system copy deletion process removes partition and all associate objects from source system without affecting the performance of storage partition migrated system.
• Features for aborting and rolling back the storage partition migration: If the user wishes to, they can simply abort the migration till control is at the system from which it started, and after switching the control to storage partition migrated system, rollback operation will bring back the IO operations to the system from which the partition migration began.

Conclusion
The improvements in Non-disruptive Storage Partition Migration Technology greatly increase usability by automating important processes and offering useful solutions. These developments provide a smooth, effective data mobility experience and enable users to make well-informed decisions.
