The IBM 2026 TotalStorage SAN16M-2 Express Model (part number 202616E) Model 16E switch is designed to address the needs of entry-level SAN applications, such as simple first-time SAN deployments, and application-specific deployments, in a half-rack width configuration. It starts at a base of 8 non-blocking ports that use industry standards-based auto-sensing and auto-rate-negotiation, for 1, 2, and 4 Gbps speeds (4 Gbps speeds require 4 Gbps compatible hardware). The SAN16M-2 Express Model can be upgraded in four-port increments to 12 or 16 ports, and offers an optional, second power supply for those environments that require higher levels of redundancy. Improved installation and configuration wizards also help provide greater ease-of-use.
