Integrated FCIP for Remote SAN Extension
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 Cisco MDS 9000 18/4-Port Multiservice Module uses the open-standards FCIP protocol to extend the distance of current Fibre Channel solutions, enabling interconnection of SAN islands over extended distances.
Advanced SAN Extension Features
The Cisco MDS 9000 18/4-Port Multiservice Module supports hardware-based FCIP compression to increase the effective WAN bandwidth of SAN extension solutions.
The Cisco MDS 9000 18/4-Port Multiservice Module supports 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 encryption provide a high-performance, highly secure SAN extension capability.
Additionally, the Cisco MDS 9000 18/4-Port Multiservice 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. Similarly, the module supports FCIP tape acceleration, which significantly improves throughput over WAN links for remote tape backup and restore operations. Further, the Cisco IOA feature allows deployment of write acceleration and tape acceleration over PortChannels to achieve higher availability and resiliency.
Cisco I/O Accelerator
The Cisco MDS 9000 IOA Package provides SCSI acceleration to dramatically increase the number of SCSI I/O operations per second over long distances spanned by Fibre Channel and FCIP links by reducing the effect of transport latency on the processing of each operation. The Cisco IOA feature, through a transport- and speed-independent implementation, provides a unified solution for 1-, 2-, 4-, 8-, and 10-Gbps links over MANs and WANs. The Cisco IOA feature optimizes the utilization of MAN resources for backup and replication by enabling hardware-based compression.
Cisco IOA services can be inserted transparently into the fabric, and no fabric reconfiguration or rewiring is required. Cisco's clustering technology enables transparent provisioning, high availability, and failover capabilities.
Cisco Storage Media Encryption
Cisco SME services offer solutions that enable companies to address Payment Card Industry (PCI) Data Security Standard (DSS) 2.0 compliance and other legislative regulations such as the Health Insurance Portability and Accountability Act (HIPAA that require companies to store and protect data at rest for a specified number of years while publicly disclosing security breaches. Cisco has services such as IP Security (IPsec) and the Cisco TrustSec
® solution to address data security while data is in motion. Cisco SME addresses data security for data at rest. Cisco SME is a fabric-based service so is scalable and nonintrusive and addresses heterogeneous environments.
• Cisco SME enables data on tapes and VTLs to be compressed, encrypted, and authenticated for centralized security management and data management and recovery.
• Cisco SME enables encryption of data for disk arrays.
• Cisco SME services employ clustering technology to create a highly available solution. The cryptographic cluster formed enhances reliability and availability, provides automated load balancing and failover capabilities, and simplifies provisioning as a single SAN fabric service rather than as individual switches or modules.
• The Cisco Key Management Center (KMC) provides comprehensive key management for Cisco SME, with support for single- and multiple-site deployments. Cisco KMC provides essential features such as key archival, secure export and import and translation for distribution, and key shredding. It can also work in conjunction with the RSA RKM Appliance.
• The Cisco SME license can be used to enable encryption of either tapes or disks. Cisco recommends that separate service engines be used for Cisco SME tape and disk services.
Cisco Data Mobility Manager
The Cisco DMM is a fabric-based data migration solution that transfers block data nondisruptively across heterogeneous storage volumes and across distances, whether the host is online or offline. This data center-class solution helps address the challenges of data migration, such as downtime, the need to add data migration software to servers, and the potential for data loss and corruption. By simply enabling the DMM feature on the Cisco MDS 9000 18/4-Port Multiservice Module located anywhere in the SAN, IT administrators can configure data migration without host agents, without rewiring, with little effect on performance, and without downtime.
Ideal for efficient, secure SAN consolidation, ANSI T11-standard VSANs enable 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 maintained with its own fabric services for added scalability and resilience. VSANs allow the cost of SAN infrastructure to be shared among more users, while helping ensure segregation of traffic and retaining independent control of configuration on a VSAN-by-VSAN basis.
Integrated SAN Routing
In another step toward deployment of efficient, cost-effective, consolidated storage networks, the Cisco MDS 9000 18/4-Port Multiservice Module supports IVR, the industry's first routing function 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. 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. IVR means lower total cost of SAN ownership.
Integrated Mainframe Support and Channel Extension
The Cisco MDS 9000 18/4-Port Multiservice Module is mainframe ready, with full support for IBM zSeries FICON and Linux environments.
Certified by IBM for attachment to all FICON-enabled devices in an IBM zSeries operating environment, the Cisco MDS 9000 18/4-Port Multiservice 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 intermixing of SAN resources among IBM z/OS, mainframe Linux, and open systems environments, enabling increased SAN utilization and simplified SAN management. VSAN-based intermix mode eliminates the uncertainty and instability often associated with zoning-based intermixing techniques. The use of VSANs also greatly reduces the likelihood that misconfiguration or component failure in one VSAN will affect 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 command-line interface (CLI), or IBM CUP-enabled management tools including the IBM SA/390 Resource Measurement Facility (RMF) and dynamic channel path management (DCM).
The combination of the SAN Extension over IP license and the Mainframe license enables FICON tape write and read acceleration, often referred to as tape pipelining. The further addition of the Cisco XRC Acceleration feature improves performance and bandwidth utilization over WAN links for IBM z/OS Global Mirror dynamic updates.
Advanced Traffic Management
The advanced traffic management capabilities integrated into the Cisco MDS 9000 18/4-Port Multiservice Module simplify deployment and optimization of large-scale fabrics.
• Virtual output queuing: Helps ensure line-rate performance on each port, independent of traffic pattern, by eliminating head-of-line blocking
• Up to 4095 buffer-to-buffer credits: Can be assigned to an individual port for increased bandwidth utilization across long distances
• PortChannels: Allow users to aggregate up to 16 physical ISLs into a single logical bundle, providing optimized bandwidth utilization across all links; the bundle can consist of any speed-matched ports from any module in the chassis, helping ensure that the bundle can remain active even in the event of a module failure
• Fabric Shortest Path First (FSPF)-based multipathing: Provides the intelligence to load-balance across up to 16 equal-cost paths and, in the event of a switch failure, dynamically reroute traffic
• QoS: Can be used to manage bandwidth and control latency and to prioritize critical traffic
• Fibre Channel congestion control: Provides end-to-end, feedback-based congestion control that augments the Fibre Channel buffer-to-buffer credit mechanism, enabling enhanced traffic management
Advanced Diagnostics and Troubleshooting Tools
Management of large-scale storage networks requires proactive diagnostics, tools to verify connectivity and route latency, and mechanisms for capturing and analyzing traffic. The Cisco MDS 9000 Family integrates the industry's most advanced analysis and diagnostic tools. Power-on self test (POST) and online diagnostics provide proactive health monitoring. The Cisco MDS 9000 18/4-Port Multiservice Module implements diagnostic capabilities such as Fibre Channel Traceroute to detail the exact path and timing of flows and Switched Port Analyzer (SPAN) to intelligently capture network traffic. After traffic has been captured, it can be analyzed with the Cisco Fabric Analyzer, an embedded Fibre Channel analyzer. Comprehensive port-based and flow-based statistics facilitate sophisticated performance analysis and service-level agreement (SLA) accounting. With the Cisco MDS 9000 family, Cisco delivers a comprehensive toolset for troubleshooting and analysis of storage networks.
Comprehensive Solution for Robust Network Security
Addressing the need for fail-proof security in storage networks, the Cisco MDS 9000 18/4-Port Multiservice Module offers an extensive security framework to protect highly sensitive data moving in today's enterprise networks. The module employs intelligent frame inspection at the port level, including the application of ACLs for hardware enforcement of zones, VSANs, and advanced port security features.
• Extended zoning capabilities are enabled to help ensure that LUNs can be accessed by only specific hosts (LUN zoning), to limit SCSI read commands for a certain zone (read-only zoning), and to restrict broadcasts to only the selected zones (broadcast zones).
• VSANs are used to achieve higher security and greater stability by providing complete isolation among devices that are connected to the same physical SAN.
• FC-SP provides switch-switch and host-switch Diffie-Hellman Challenge Handshake Authentication Protocol (DH-CHAP) authentication supporting RADIUS and TACACS+, helping ensure that only authorized devices can access protected storage networks.
• For both FCIP and iSCSI deployments, the comprehensive IPsec protocol suite delivers secure authentication, data integrity, and hardware-based encryption.
Advanced Software Packages
The Cisco MDS 9000 18/4-Port Multiservice Module can be further enhanced through additional software packages that offer advanced intelligence and functions. Currently available software packages include:
• Cisco MDS 9000 SME Package: Cisco SME secures data stored on heterogeneous disk arrays, tape drives, and VTLs using the Cisco MDS 9000 18/4-Port Multiservice Module.
• Cisco SAN Extension over IP Package: The Cisco SAN Extension over IP Package provides an integrated, cost-effective, and reliable business continuance solution that uses IP infrastructure by offering FCIP for remote SAN extension, along with a variety of advanced features to optimize the performance and manageability of FCIP links. When the Mainframe Package license is installed on the switch or director containing the Cisco MDS 9000 18/4-Port Multiservice Module, FICON channel extension features are enabled as well.
• Cisco MDS 9000 IOA Package: The Cisco IOA feature provides SCSI acceleration to dramatically increase the number of SCSI I/O operations per second over long distances spanned by Fibre Channel and FCIP links by reducing the effect of transport latency on the processing of each operation.
• Cisco MDS 9000 SSE Package: Cisco SSE provides the underlying infrastructure and programmatic interface to enable intelligent fabric applications. The Cisco MDS 9000 SSE Package enables network-hosted storage applications and network-assisted storage applications such as SANTap for EMC RecoverPoint on the Cisco MDS 9000 18/4-Port Multiservice Module.
• Cisco MDS 9000 XRC Acceleration Package: The Cisco XRC Acceleration feature provides acceleration of z/OS Global Mirror (often referred to by its former name of XRC) dynamic updates across WAN links between primary FICON disk storage (direct-access storage device [DASD]) and the remote IBM System Data Mover (SDM) System z.
