IBM FlashSystem Specs
FlashSystem model specifications organized around practical buyer questions: bandwidth, latency, raw capacity, effective capacity, I/O ports, FCM support, and best-fit workloads.
Specs matter only when they answer a decision. Start with workload and architecture, then use model specifications to test whether a system has enough throughput, low enough latency, enough usable capacity, and the right expansion path.

IBM FlashSystem 5600
Current-generation 1U NVMe FlashSystem for smaller mixed workloads, compact OLTP, IBM Power attachment, edge deployments, and buyers who need a serious array without jumping to the 7600 tier.
IBM FlashSystem 7600
Current-generation 2U FlashSystem for larger mixed workloads, consolidated virtualized environments, analytics platforms, and buyers comparing the 7300 successor class.
IBM FlashSystem 9600
Current-generation flagship 2U FlashSystem for critical OLTP, consolidated mixed workloads, very high capacity, high bandwidth, and buyers comparing 9500-class refresh paths.
IBM FlashSystem C200
Capacity-optimized FlashSystem for backup, sequential, archive, media, and cost-sensitive high-capacity workloads where flash density and durability matter.
IBM FlashSystem 5000
Entry FlashSystem family category for smaller mixed workloads, backup, hybrid flash, and buyers searching older 5015, 5035, and 5045 paths.
IBM FlashSystem 5300
High-interest 1U NVMe FlashSystem still generating warehouse exposure, especially around 20 TB to 30 TB environments, datasheets, control enclosures, and refresh questions.
IBM FlashSystem 7300
High-interest midrange FlashSystem model for buyers comparing 7300-class replacements, Hitachi VSP One Block, Dell PowerStore, Pure Storage, and the current 7600 tier.
IBM FlashSystem 9500
Previous flagship FlashSystem class for large mixed workloads, critical OLTP, and refresh conversations that usually point toward the current FlashSystem 9600 tier.
IBM Storwize V7000 Migration Path
Storwize V7000 remains a major query and migration signal. This profile frames the replacement decision toward FlashSystem 7600, 9600, or another architecture based on workload and risk.
