IBM FlashSystem Enterprise Storage

IBM FlashSystem is IBM's enterprise storage family for high-performance databases, virtualization, IBM Power Systems, business-critical applications, cyber-resilient storage, backup, hybrid cloud and data-intensive workloads. IBM FlashSystem storage ranges from compact entry-level systems to high-performance enterprise NVMe platforms capable of supporting millions of IOPS and multi-petabyte storage environments.

Modern IBM FlashSystem systems combine IBM FlashCore Module technology, NVMe storage and IBM Storage Virtualize with enterprise data services such as compression, data reduction, encryption, snapshots, replication, high availability, storage virtualization and cyber-resilience capabilities. Because much of the FlashSystem portfolio uses the same IBM Storage Virtualize software foundation, organizations can maintain a consistent approach to storage management as capacity and performance requirements grow.

Midland Information Systems provides IBM FlashSystem systems, FlashCore Modules, NVMe flash drives, SAS drives, expansion enclosures, connectivity options, upgrades and replacement parts for current and previous-generation FlashSystem models. Systems can be configured according to capacity, performance, host connectivity, availability and workload requirements.
