What is iSCSI?
Block storage has long been the backbone of critical business systems. As data volumes grow exponentially, organizations face mounting challenges in ensuring efficient, reliable storage performance. iSCSI (SCSI over IP) has emerged as a dominant technology, leveraging existing high-speed IP networks—now exceeding 100 Gbit/sec—to provide cost-effective, flexible storage access. However, the complexity of running block storage on shared IP networks often creates blind spots in performance monitoring and can obscure the impact of competing traffic.
