Software feature limits

Edit online

FlashSystem 5200 runs the IBM® Storage Virtualize software stack to provide its rich storage functionality.

The following features require a minimum of 128 GB memory per node:
  • Policy-based replication for disaster recovery (DR)
  • Policy-based high availability (HA)
  • Policy-based HA and DR (3-site replication)
  • Partition Migration
  • Storage Insights Integration (Cloud Call-home)
  • Ransomware Threat Detection
  • Deduplication

The Configuration limits page provides further information, including:
  • The maximum number of objects that can be configured or used per system.
  • The capacity that can be configured for use with software features such as RAID, replication, and snapshots.
  • Multi‑system considerations such as FlashSystem grid and partnerships.
  • Ecosystem considerations such as Ethernet sessions and round‑trip times.
