Advanced SAN Extension Features
The Cisco MDS 9000 Family Multiprotocol Services Module supports FCIP compression to maximize the effective WAN bandwidth of SAN
extension solutions. The Cisco MDS 9000 Family Multiprotocol Services Module achieves up to a 30:1 compression ratio, with typical ratios of
2:1 over a wide variety of data sources. With the addition of hardware-based compression, the MDS 9000 Family Multiprotocol Services Module
is able to provide optimal levels of compressed throughput for implementations across both low-bandwidth and high-bandwidth links.
The Cisco MDS 9000 Family Multiprotocol Services Module supports IPSec encryption for secure transmission of sensitive data over extended
distances. Hardware enablement of IPSec ensures high throughput. Used together, hardware-based compression and hardware-based encryption
provide high performance, highly secure SAN extension capability.
Additionally, the MDS 9000 Family Multiprotocol Services Module supports FCIP Write Acceleration, a feature that can significantly improve
application performance when storage traffic is extended across distance. When FCIP Write Acceleration is enabled, WAN throughput is optimized
by reducing the latency of command acknowledgments. Similarly, the Cisco MDS 9000 Family Multiprotocol Services Module supports FCIP Tape
Acceleration, which significantly improves throughput over WAN links for remote tape backup operations.
Virtual SANs
Ideal for efficient, secure SAN consolidation, VSANs allow more efficient storage network utilization by creating hardware-based isolated
environments with a single physical SAN fabric or switch. Each VSAN can be zoned as a typical SAN and maintains its own fabric services for
added scalability and resilience. VSANs allow the cost of SAN infrastructure to be shared among more users, while ensuring absolute segregation
of traffic and retaining independent control of configuration on a VSAN-by-VSAN basis.
Integrated SAN Routing
In another step toward deploying efficient, cost-effective, consolidated storage networks, the Cisco MDS 9000 Family Multiprotocol Services
Module supports IVR, the industry’s first routing functionality for Fibre Channel. IVR allows selective transfer of data between specific initiators
and targets on different VSANs while maintaining isolation of control traffic within each VSAN. With IVR, data can transit VSAN boundaries
while maintaining control plane isolation, thereby maintaining fabric stability and availability. Integrated IVR eliminates the need for external
routing appliances, greatly increasing routing scalability while delivering line-rate routing performance, simplifying management, and eliminating
the challenges associated with maintaining separate systems. Integrated IVR means lower total cost of SAN ownership.
Integrated Mainframe Support
The Cisco MDS 9000 Family Multiprotocol Services Module is mainframe-ready with full support for IBM zSeries FICON and Linux
environments. Qualified by IBM for attachment to all FICON-enabled devices in an IBM zSeries operating environment, Multiprotocol Services
Module supports transport of the FICON protocol in both cascaded and non-cascaded fabrics, as well as an intermix of FICON and open systems
Fibre Channel Protocol traffic on the same switch. Virtual SANs simplify intermix of SAN resources between z/OS, mainframe Linux, and open
systems environments, allowing for increased SAN utilization and simplified SAN management. VSAN-based intermix mode eliminates the
uncertainty and instability often associated with zoning-based intermix techniques. VSANs also greatly reduce the probability of a misconfiguration
or a component failure in one VSAN affecting operation in other VSANs. VSAN-based management access control simplifies partitioning of SAN
management responsibilities between mainframe and open systems environments, enhancing security. FICON VSANs can be managed using the
integrated Cisco Fabric Manager, Cisco CLI, or IBM CUP-enabled management tools including SA/390 Resource Measurement Facility (RMF), or
Dynamic Channel Path Management (DCM).
