158222-b21 HP StorageWorks 8 Port Fiber Channel 1Gb/s SAN Network Switch

HP StorageWorks 158222-b21

Build a fast, resilient storage network with the HP 158222-b21, a 1Gb/s Fibre Channel switch for enterprise SAN fabrics supporting databases, virtualization clusters and backup environments.

It provides 8 Fibre Channel ports for connecting host bus adapters, storage controllers and inter-switch links. Operating at up to 1Gb/s per port, it delivers the low-latency, lossless transport that block storage needs. Fibre Channel zoning lets administrators isolate storage traffic and control which hosts can see which LUNs. Transceiver speed ratings matter in Fibre Channel, so match optics to your target speed. The 158222-b21 works well for fabric expansion or like-for-like replacement. For high availability, many SAN designs use two independent fabrics so that every server and array has redundant paths. ISLs connect additional switches when you need more ports. A separate storage fabric means LAN congestion does not affect disk I/O.

Matching switch models across fabrics simplifies firmware and support. With zoning, administrators decide exactly which hosts can see which storage targets. Storage vendors publish interoperability matrices worth checking before rollout. Good fabric design makes data migration and array expansion much easier. Fibre Channel was purpose-built for storage and delivers frames reliably and in order. Install switches in pairs where possible so that maintenance on one fabric does not interrupt storage access. Whether you are building a new network or replacing an existing unit, the 158222-b21 delivers storage area network connectivity that fits the job.
