Cisco Systems DS-X9304-18K9 The Cisco MDS 9000 Family 18/4-Port Multiservice Module is optimized for deployment of high-performance storage area network (SAN) extension solutions, distributed intelligent fabric services, and cost-effective IP storage and mainframe connectivity in enterprise storage networks.The Cisco MDS 9000 Family 18/4-Port Multiservice Module uses Cisco expertise and knowledge of IP networks to deliver outstanding SAN extension performance, minimizing latency for disk and tape 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.Natively integrating support for intelligent fabric applications, the Cisco MDS 9000 Family 18/4-Port Multiservice Module provides a platform for distributed fabric services such as storage media encryption (SME), which encrypts data at rest on heterogeneous tape drives and virtual tape libraries (VTLs). The Cisco MDS 9000 Family 18/4-Port Multiservice Module transparently offers such advanced functions to any device connected to the fabric, facilitating ease of deployment, scalability, and high availability through clustering.
