Awesome storage.

We utilize SVC and FlashSystem as production storage for our IBMi and VMware environments, and a standalone Flash system for the DR site. We use the SVC Enhanced Stretch cluster as an HA solution for the production site, on top of it, IBMi PowerHA, and a VMware stretched cluster. We then perform PBR for DR purposes and trigger a Safeguarded Snapshot for Cyber Resilience.

Safeguarded Snapshots and PBR. Since we adopted PBR we have seen a massive reduction of our asynchronous replication delays. We can easily be compliant with our expected RPO, and basically we are almost everytime at RPO=0, without changing anything in the infrastructure . We love as well the huge performance and high compression rates delivered by FlashCore Modules, that allow us to save money while keeping our applications performing as desired.

We have been using FlashSystem for many years, so we have seen a constant increase in features and performance all over the years. Now, with PBR and Snapshots, we have achieved lower RPO and better security. Snapshot, are now easier to use, thanks to the new integrated policies, allowing for internal setup of scheduling and retention.

Probably we could evaluate different systems if they had the same level of integration with IBM Power Systems servers and IBMi OS. But, as far as we know there is no other oprtion in the storage market that offers suche a complete compatibility with those systems. So I don't think we'll go anywehere else
