Product overview The 24/10-Port SAN Extension Module The capabilities of IBM Storage Networking SAN384C-6 can be extended with modules. The 24/10-Port SAN Extension Module is supported on IBM Storage Networking c-type Family Multilayer  Directors. With 24 line-rate 2-, 4-, 8-, 10-, and 16-Gbps Fibre Channel ports and eight 1 and 10 Gigabit  Ethernet FCIP ports, this module enables large and scalable deployment of SAN extension solutions. The  SAN extension module has two independent service engines that can each be individually and  incrementally enabled to scale as business requirements expand.  The SAN extension module supports the full range of services available on other IBM Storage Networking  c-type Family Fibre Channel switching modules, including virtual SAN (VSAN), security, and traffic  management services. The FCIP module uses IBM expertise and knowledge of IP networks to deliver  outstanding SAN extension performance, reducing latency for disk and tape operations with FCIP  acceleration features, including FCIP write acceleration and FCIP tape write and read acceleration.  Hardware-based encryption helps secure sensitive traffic with IP Security (IPsec), and hardware-based  compression dramatically enhances performance for both high- and low-speed links, enabling immediate  cost savings in expensive WAN infrastructure. Multiple FCIP interfaces within a single engine or across  service engines can be grouped into a port channel of up to 16 links for high availability and increased  aggregate throughput.
