Overall Satisfaction with Hitachi Storage Virtualization Operating System (SVOS)

The main challenge that is addressed by Hitachi Storage Virtualization Operating System (SVOS) is managing diverse and ever-growing data volumes/workloads. Helps in structured, unstructured, semi-structured data types. It has significantly solved the performance, latency and scaling challenges which traditional architectures struggle to adapt.

Hitachi Storage Virtualization Operating System (SVOS) has optimized the storage significantly. It supports the moving data between tiers , hence the capacity is allocated only when needed. This has lead to lowering the storage cost per unit data & scaling flexibility.

Pros

  • Scaling Flexibility
  • Supporting Hybrid/Cloud environments
  • Improving cost efficiency
  • Simplifying storage management

Cons

  • Better user interface
  • Unified storage to fit mid-market needs
  • Complex installation process
  • Pooled external & internal storage into one resource & increased utilization by 40%
  • Reduces raw capacity needs by 50 - 70%
It combines with enterprise level storages very well. Due to its high reliability & uptime, it is valued greatly by such institutes. Secondly, it's advanced virtualization reduces the complexity & cost, which in turn results in maximizing hardware utilization.
Performance efficiency is amazing even under heavy workloads. Built-in cache optimization and automated tiering help ensure efficient data placement.
There are few points due to which Hitachi Storage Virtualization Operating System (SVOS) is better than ONTAP. Firstly, it is designed is such a way that it can virtualize any vendor's block storage which ONTAP cannot do in specific cases. It's amazing virtualization power offers unified control plane & storage pane.

It's performance & predictability offers iops scalabililty which depends heavily on cluster configuration in case of ONTAP.
