451439B21R HP BLC Cisco Catalyst 1GBE 3120X 4-Port Blade SAN Network Switch

HP BLC Cisco Catalyst 451439B21R

The HP BLC Cisco Catalyst 451439B21R is a Fibre Channel blade switch designed for storage area networks that connect servers to disk arrays, all-flash storage and tape libraries.

It provides 4 Fibre Channel ports for connecting host bus adapters, storage controllers and inter-switch links. Fibre Channel zoning lets administrators isolate storage traffic and control which hosts can see which LUNs. Integrated in the blade enclosure, it gives blade servers direct SAN access with fewer cables. Transceiver speed ratings matter in Fibre Channel, so match optics to your target speed. Keeping storage on its own fabric shields it from LAN traffic spikes. Dual, independent fabrics are a common SAN design for redundant server-to-storage paths. The HP 451439B21R works well for fabric expansion or like-for-like replacement. As storage grows, inter-switch links let you extend the fabric.

With zoning, administrators decide exactly which hosts can see which storage targets. Check compatibility with your blade enclosure model and I/O bay before ordering. A clean SAN design simplifies growth, migrations and cluster expansion. Deploying switches in pairs allows non-disruptive maintenance. Matching switch models across fabrics simplifies firmware and support. Review your storage vendor's interoperability guidance to confirm supported firmware levels before deployment. Add the HP 451439B21R to your network for reliable storage networking you can depend on.
