Flash storage continues to mature as vendors including IBM, Dell EMC, HPE, Hitachi Vantara, and Pure Storage adopt the latest technologies including NVMe, low-cost QLC flash, and Intel Optane while using software to help squeeze even more performance.
IBM in February said it would eliminate two of its primary non-mainframe storage lines--Storwize and the Flash Systems A9000--and replacing them with a single new FlashSystem family. The FlashSystem family includes five new storage arrays, all running the same IBM Spectrum Virtualize software platform, which IBM said helps simplify customers‘ entire storage environment by supporting over 500 multi-vendor storage systems, and offering enterprise-class data services and non-disruptive data movement all controlled by a single management plane.
The new IBM FlashSystem family also offers 99.9999-percent availability, full hardware redundancies, and two-site or three-site replication, and provide seamless hybrid multi-cloud support with a a full range of security capabilities. Three of the five models offer NVMe flash and Fibre Channel NVMe host connectivity, high-performance data compression with FlashCore Modules, external storage virtualization of non-IBM storage, and expandability with storage class memory.
