It’s been a while since we posted an update here, and the reason is that although version 12.3.0 was already released back in November 2018, version 12.3.1 is the real enabler of version 12.3.0.
What does “enabler” mean? Well for A9000R rack systems, version 12.3.1 enables the non-disruptive expansion of the new minimal rack configuration that was introduced together with version 12.3.0. Without version 12.3.1, that new minimal rack configuration was not possible.
Of course, it’s not just about rack expansion (adding grid controllers and flash enclosures) for A9000R. Version 12.3.1, on top of the range of features that were already introduced in version 12.3.0, offers a unique capacity management feature: Deduplication-aware capacity management.
Simply put (as shortly as possible), deduplication-aware capacity management is a capacity management enhancement that reports actual and more granular estimates of physical and reclaimable capacity per volume, as well as estimates of deduplication and compression ratios. This enhancement drills into vast amounts of metadata, and analyzes it without any performance impact, using advanced heuristics that are proven to produce accurate estimates.
But that’s only in a nutshell. The deduplication-aware capacity management feature itself is enabled through Hyper-Scale Manager version 5.5.1.
To quickly summarize the features that were already introduced in version 12.3.0 for both A9000 and A9000R:
- Multi-site high availability (HA) and disaster recovery (DR).
- Removal of storage pool size limitation (was 1 PB).
- Monitor internal/external latency at the system level.
- Pending deletion indication.
- Option for using a longer user password of up to 64 characters.

Until the next version!
