Integrated IP storage services in a high -density form factor: The module supports eight 1- and   10-Gigabit Ethernet ports. Individual ports can be configured with hot-swappable shortwave and  longwave Small Form-Factor Pluggable (SFP) connections. Integrated hardware-based VSANs and IVR: The module enables deployment of large-scale multisite   and heterogeneous SAN topologies. Integration into port-level hardware allows any port in a system  or fabric to be partitioned into any VSAN. Integrated hardware-based IVR provides line-rate routing  between any ports in a system or fabric without the need for external routing appliances. Intelligent network services : The module uses VSAN technology for hardware-enforced, isolated   environments in a single physical fabric, access control lists (ACLs) for hardware-based intelligent  frame processing, and advanced traffic management features such as fabric-wide QoS to facilitate  migration from SAN islands to enterprise wide storage networks. Sophisticated diagnostics: The module provides intelligent diagnostics, protocol decoding, and   network analysis tools as well as integrated IBM Call Home capability for greater reliability, faster  problem resolution, and reduced service costs. Comprehensive network security framework : The module supports RADIUS and TACACS+, FC-SP,   Secure File Transfer Protocol (SFTP), Secure Shell (SSH) Protocol, Simple Network Management  Protocol Version 3 (SNMPv3) implementing the Advanced Encryption Standard (AES), VSANs,  hardware-enforced zoning, ACLs, and per-VSAN role-based access control (RBAC). RBAC provides  separate control over management functions and access on a per-VSAN basis, enabling separation  of duties among administrators on the same physical switch. Gigabit Ethernet ports support IPsec  authentication, data integrity, and hardware-assisted data encryption. IP Version 6 (IPv6) support: The module supports IPv6 as mandated by the US Department of   Defense (DoD), Japan, and China. IPv6 support is provided for FCIP and for management traffic  routed in band and out of band. Data-distribution, data-protection, and business-continuance services are significant components of  today’s information-centered businesses. The capability to efficiently replicate critical data on a global  scale helps ensure a higher level of data protection for valuable corporate information, and also increases  utilization of backup resources and lowers total cost of storage ownership. The 24/10-Port SAN Extension  Module uses the open-standards FCIP protocol to extend the distance of current Fibre Channel and  FICON solutions, enabling interconnection of SAN islands over extended distances.  Integrated FCIP for remote SAN and mainframe channel extension Advanced SAN extension features The 24/10-Port SAN Extension Module supports hardware-based FCIP compression to increase the  effective WAN bandwidth of SAN extension solutions. The module can deliver compression ratios in the  range of 4:1 to 5:1 over a wide variety of data sources. The SAN extension module supports AES 256 IPsec encryption for secure transmission of sensitive data  over extended distances. Hardware enablement of IPsec helps ensure line-rate throughput. Together,  hardware-based compression and hardware-based encryption provide a high-performance, highly secure  SAN extension capability. Additionally, the SAN extension module supports FCIP write acceleration, a feature that can significantly  improve application performance when storage traffic is extended across long distances. When FCIP  write acceleration is enabled, WAN throughput is optimized by reducing the latency of command  acknowledgments. 5 IBM Storage Networking SAN192C-6 Product Guide
