New Chassis-Based and Stackable Switches Broaden D-Link's Cost-Effective, High-Performance Unified Networking Solutions for Small and Medium-Sized Businesses

D-Link's Superior Economic Model and Range of Standards-Based Switches Ensure Businesses Don't Have to Settle for Complex, Premium Priced Hardware With Service Fees

FOUNTAIN VALLEY, CA -- (Marketwire) -- 05/10/11 -- D-Link, the cost-effective, standards-based unified networking solutions provider for small business and medium enterprise IT environments, today broadened its selection of scalable switching solutions, providing an exceptional portfolio for small and medium-sized businesses. The D-Link® DGS-6604 chassis-based switch, DGS-3620 and DGS-3120 xStack® series switches deliver superior performance, 10-Gigabit Ethernet (10GE) aggregation, and Power Over Ethernet (PoE) support with the flexibility of D-Link's standards-based architectures. These new cost-effective switches enable businesses to future-proof their networks with field-proven IPv6 capabilities, high availability for mission critical applications, enhanced security, and simplified management.

D-Link Delivers on Flexibility and Affordability
D-Link® unified networking solutions offer small and medium-sized businesses scalability, reliability, performance, and lower initial and ongoing costs. Through D-Link's superior economic model, businesses can take advantage of these affordable networking solutions in multi-vendor IT infrastructures without being locked into proprietary hardware, software or service requirements.

"As data-rich applications and bandwidth demands continue to grow, businesses require affordable switches in a choice of stacking or chassis-based configurations. Switches must also offer IPv6 compatibility, deliver high-performance, availability and offer seamless integration with other network components," said Ken Loyd, director of product marketing, D-Link Systems, Inc. "According to Gartner, D-Link is the number one provider of Ethernet ports shipped to small enterprise and number two provider of Ethernet ports shipped to enterprises worldwide(1), demonstrating our commitment to delivering networking solutions with the features and capabilities that our customers need."

D-Link Comprehensive IPv6 Support
The DGS-6604, DGS-3620 and DGS-3120 series switches go beyond IPv6 certification. D-Link's field-proven interoperability with IPv6 expertise future-proofs your network for the next phase of the Internet, and provides new capabilities that can simplify network operations. Beyond passing the IPv6 Ready Logo Phase II test criteria -- which expands the "core IPv6 protocols" test coverage to approximately 450 tests including new test categories, and verification of optimum compliance -- D-Link already has multiple customers running production IPv6 networks. D-Link IPv6 support includes IPv6 Tunnel, ICMPv6, IPv6 Neighbor Discovery, DHCPv6, RIPng, and OSPFv3.

DGS-6604 Chassis Switch, DGS-3620 and DGS-3120 xStack® Switch Features
The DGS-6604 is a cost-effective chassis-based solution, ideal for environments that require high availability of network applications. Its flexible modular architecture enables simple, cost-effective future expansion based on a high-speed switch fabric with capacity of up to 576 Gbps and system performance of up to 428 Mpps.

Other important DGS-6604 features include:

  • Superior Performance: Bottleneck free distributed packet switching/routing; intelligent line cards with on-board Level 2 (L2)/Level 3 (L3)/Level 4 (L4) switching controllers
