I like all the features, but the most impressive recently has been the introduction of IBM's Flash Core Modules. They are a form of a flash drive, but they have many more features.
IBM Spectrum Virtualize extends back-end storage capabilities with advanced features, ensuring transparency and integration across hardware. It normalizes storage into a single driver, simplifying management and reducing costs. Non-disruptive migrations and self-tuning enhance efficiency. However, it needs improved Fibre Channel support and enhanced Level 1 support. Disk reliability and a complicated migration process pose challenges, and scalability is limited to eight nodes, which restricts enterprise scalability.
