Cisco ONS 15500 Series

Cisco ONS 15530 DWDM Multiservice Aggregation Platform



The Cisco® ONS 15530 is a highly scalable, dense wavelength-division multiplexing (DWDM), multiservice aggregation platform that integrates storage, data networking, and legacy applications over an ultra-high-bandwidth, intelligent optical infrastructure. The Cisco ONS 15530 provides flexible, scalable, and highly available optical networking for high-performance, bandwidth-intensive networking applications.

Cisco ONS 15530 Multiservice Aggregation Platform


• High-density service aggregation-Provides industry-leading aggregation capabilities with up to 8 ports of Fibre Channel, IBM Fiber Connection (FICON), or Gigabit Ethernet, or up to 40 ports of Enterprise System Connection (ESCON) on a single wavelength. Service aggregation of 2 Gbps Fibre Channel/FICON-Support for up to 4 ports of 2 Gbps Fibre Channel or 2 Gbps FICON services per wavelength.

• Multiservice support for complete network consolidation-Customers have a single scalable platform that supports low-speed copper legacy services such as T1/E1 (PBX interconnect), OC-3/STM-1, Fast Ethernet, and D1 video, in addition to high-density Gigabit Ethernet, Fibre Channel, FICON, and ESCON services.

• Capacity-Fiber capacity is maximized when used with a 32-wavelength system, such as the Cisco ONS 15540, providing up to 256 Fibre Channel, FICON, or Gigabit Ethernet services or up to 1280 ESCON services on a single fiber pair.

• Scalability-Providing customers with the flexibility to grow their networks over time, the Cisco ONS 15530 can support 2.5 Gbps wavelengths for initial deployments of low-density applications and then scale up to 10 Gbps wavelengths for high-density applications.

• Service mixing-With a scalable switch fabric, the Cisco ONS 15530 provides the ability to mix a combination of Fibre Channel, FICON, ESCON, and Gigabit Ethernet services over the same wavelength, maximizing the carrying capacity of the metro DWDM network.

• Transparency-Through the use of protocol-independent transponders and service aggregation cards, a customer can network several services such as ESCON, 1 Gbps and 2 Gbps FICON, 1 Gbps and 2 Gbps Fibre Channel, Gigabit Ethernet, Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH), Asynchronous Transfer Mode (ATM), digital video, Sysplex Timer (external throughput rate [ETR] and control link oscillator [CLO]), and Coupling Link (ISC1 or ISC3 compatibility mode, or ISC3 peer-to-peer mode). Customers can perform network consolidation of all their storage, data networking, and legacy applications over a single, resilient metro DWDM network.

• Certifications-Fully compatible with storage solutions from Cisco partners, including IBM GDPS, EMC SRDF, HP/Compaq DRM, and HDS TrueCopy, allowing customers the flexibility of deploying the Cisco ONS 15530 platform in many types of storage environments.

• Management-The Cisco ONS 15530 system, based on Cisco IOS® Software, easily integrates into existing Cisco networks using CiscoWorks CiscoView, Simple Network Management Protocol (SNMP), Cisco Transport Manager providing reduced training and management costs. Per-wavelength and per-fiber management channels are used to monitor and manage a robust network. The Cisco ONS 15530 also offers a unique and patented per-service level Operations, Administration, Maintenance, and Provisioning (OAM&P) capability.

• Network consolidation-A customer can consolidate existing SONET/SDH and ATM networks, Ethernet-based data networks, and storage networks on a single Cisco ONS 15530 optical network. The initial deployment of a Cisco ONS 15530 network can be easily extended over time to support new applications and services.

• Cisco Systems® service and support-Easily integrates into existing service programs.

Cisco ONS 15530 Applications

• Storage-The ability to aggregate multiple storage services on a single wavelength makes the Cisco ONS 15530 ideal for use in storage networking applications. The transparent networking of ESCON, FICON, Fibre Channel, Coupling Link, Sysplex Timer, and other protocols makes the Cisco ONS 15530 the perfect solution for business continuance applications such as IBM GDPS, EMC SRDF, HP/Compaq DRM, and HDS TrueCopy.

• Data networking-Data protocols such as Gigabit Ethernet or Fast Ethernet can be cost-effectively extended over a Cisco ONS 15530 metro optical network in their native forms, without requiring complex protocol conversions between the local- and metropolitan-area networks (LANs/MANs). A flatter network hierarchy can be built that is simpler to manage, because complex protocol conversion, access, and throughput policy-based management are no longer required at the LAN/MAN convergence point. At the same time, this new patented technology offers similar levels of OAM&P capabilities typically expected in a legacy metro environment.

• Legacy-Whether a customer is overlaying new services onto their existing SONET/SDH or ATM infrastructure or entirely replacing it, the Cisco ONS 15530 can network legacy protocols in addition to the newer gigabit-speed protocols driving both data and storage networks. This feature makes the Cisco ONS 15530 a unique solution for enterprises and service providers, providing the ability to transparently extend any service.
