AG851B HP Cisco MDS 9222i MultiService Modular 22-Port Fabric Fibre Channel Network Switch

HP MDS 9222i MultiService Modular AG851B

Build a fast, resilient storage network with the HP AG851B, a Fibre Channel switch for block-storage networks where predictable latency and lossless delivery are required. This model is part of the Cisco MDS 9000 Series and runs Cisco NX-OS.

With 22 ports, it can connect multiple servers and storage targets in a single fabric or form part of a larger multi-switch SAN. Standard Fibre Channel fabric services, such as zoning and name server, support secure, well-organized storage connectivity. For high availability, many SAN designs use two independent fabrics so that every server and array has redundant paths. Fibre Channel SFP optics are speed-specific, so choose transceivers that match your target link speed. ISLs connect additional switches when you need more ports. It works well for fabric expansion or like-for-like replacement. A separate storage fabric means LAN congestion does not affect disk I/O.

Matching switch models across fabrics simplifies firmware and support. Paired switches let you service one fabric while storage access continues on the other. Match the part number AG851B against your existing equipment for a seamless replacement or expansion. Good fabric design makes data migration and array expansion much easier. Fibre Channel was designed specifically for storage traffic and delivers consistent, in-order frame delivery. Review your storage vendor's interoperability guidance to confirm supported firmware levels before deployment. For anyone sourcing Fibre Channel SAN switching, the AG851B combines HP engineering with practical, everyday performance.
