2. WHAT ENVIRONMENT IS MOST SUITABLE FOR FIBRECHANNEL SANS?

Typically, Fibre Channel SANs are most suitable for large data centers runningbusiness-critical data, as well as applications that require high-bandwidthperformance such as medical imaging, streaming media, and large databases.Fibre Channel SAN solutions can easily scale to meet the most demandingperformance and availability requirements.
