FCIP for Remote SAN Extension
Data distribution, data protection, and business continuance services are significant components of today's
information-centric businesses. The ability to efficiently replicate critical data on a global scale not only ensures a
higher level of data protection for valuable corporate information, but also increases utilization of backup resources
and lowers total cost of storage ownership. The Cisco MDS 9000 Family IP Storage Services Module uses the open-
standard FCIP protocol to break the distance barrier of current Fibre Channel solutions and enable interconnection of
SAN islands over extended distances.
Advanced FCIP Features To Enable Business Continuance And Disaster Recovery
The Cisco MDS 9000 Family IP Storage Services Module is designed to support robust business continuance
services using FCIP for remote connectivity in conjunction with a suite of advanced features, such as VSANs and
Inter-VSAN Routing (IVR), FCIP compression, FCIP Write Acceleration, and FCIP Tape Acceleration.
VSANs and IVR Enhance SAN Security and Stability
VSANs allow more efficient storage network utilization by creating hardware-based isolated environments within 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.
With their integrated FCIP capability, the Cisco MDS 9000 Family IP Storage Services Module enables the extension
of VSANs over dedicated or existing IP infrastructure.
The Cisco IP Storage Services Module supports Inter-VSAN Routing, the industry's first routing functionality for Fibre
Channel. IVR allows selective transfer of data traffic 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.
High Performance SAN Extension with Compression and FCIP Write Acceleration
The Cisco MDS 9000 Family IP Storage Services Module supports FCIP compression to maximize the effective WAN
bandwidth of SAN Extension solutions. The Cisco IP Storage Services Module achieves up to a 30:1 compression
ratio, with typical ratios of 2:1 over a wide variety of data sources. The Cisco IP Storage Services Module is able to
provide optimal levels of compressed throughput for implementations across low to intermediate-bandwidth links.
The Cisco IP Storage Services Module also 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 acknowledgements. Similarly, the Cisco IP Storage
Services Modules supports FCIP Tape Acceleration, which significantly improves throughput over WAN links for
remote tape backup operations.
Together, FCIP Compression, FCIP Write Acceleration, and FCIP Tape Acceleration enable optimal performance of
business continuance services.
iSCSI for Cost-Effective Extension of SAN Storage to Ethernet Attached Servers
Many IT managers have been hesitant to extend SAN access beyond their mission-critical applications to midrange
data center applications because of the complexity and cost involved in upgrading large numbers of midrange servers
to Fibre Channel. The Cisco MDS 9000 Family IP Storage Services Module addresses these limitations by enabling IT
organizations to extend their storage networks using cost-effective Ethernet infrastructure. All the benefits of SAN,
including increased storage utilization, centralized backups, easier addition of incremental storage capacity,
management simplification, and reduced overall total cost of ownership (TCO), can be extended to a new range of
applications. Because the Cisco IP Storage Services Module is an integral component of the Cisco MDS 9000 Family,
Ethernet attached servers will enjoy the same SAN scalability, availability, manageability, and intelligent services as
those servers connected using Fibre Channel, while maintaining the cost and ease-of-use benefits of Ethernet and IP.
Transparent and Proxy Initiator Operation
The Cisco MDS 9000 Family IP Storage Services Module provides transparent mapping of SCSI I/O operations
between iSCSI and Fibre Channel domains. When Ethernet attached servers are added to a Cisco MDS 9000 Family
storage network, they are presented to the Fibre Channel storage devices as native Fibre Channel hosts. Conversely,
Fibre Channel storage devices are presented as iSCSI targets to the iSCSI hosts. This transparent access preserves
correct operation of storage tools, such as zoning managers, which require visibility of all hosts.
Additionally, hosts have access to consistent SAN services independent of the transport they use to attach to the
SAN. As iSCSI hosts are added to the SAN, they are added to the appropriate VSAN, Fibre Channel Name Server,
Zone Server, and Cisco MDS 9000 Family management infrastructure.
