Brocade Cisco Sun Microsystems



• Provides up to 64 ports in a single domain and a 2U enclosure for higher density and more easily managed SAN fabrics with fewer domains

• Utilizes Ports on Demand capabilities for fast, easy, and cost-effective scalability from 32 to 64 ports in 16-port increments

• Enables switch consolidation throughits high port count—increasing utilization, lowering management expenses, and reducing fabric complexity

• Protects existing device investmentswith auto-configuring 1, 2, and4 Gbit/sec capabilities

• Supports full 4 Gbit/sec operations at distances up to 100 kilometers (or 500 kilometers at 1 Gbit/sec) for cost-effective business continuance

• Increases network performance with enhanced Brocade ISL Trunking, which enables a high-speed data path up to32 Gbit/sec

• Meets high-availability requirements with redundant, hot-pluggable components, non-disruptive software upgrades, and hot code activation

The EMC DS4900B is a high-performance, high-availability Fibre Channel switch that provides high port density for addressing mission-critical storage requirements. With a flexible architecture that supports 1, 2, and 4 Gbit/sec technology with 32, 48, or 64 ports, the Brocade 4900 provides an affordable high-port-count, single-domain solution. As a result, organizations with large Storage Area Network (SAN) requirements can reduce the size of their SAN footprint and simplify management by lowering the total number of domains
