Cisco SME provisioning and key management are both integrated into the Cisco Fabric Manager; no additional software is required.●Integrated Cisco Data Mobility Manager (DMM): Natively support on the Cisco MDS 9222i, Cisco DMMenables data migration between heterogeneous targets.●Platform for intelligent fabric applications:◦Cisco MDS 9222i provides hosting and acceleration of storage applications such as network-hosted volume management, data migration, and backup natively on the supervisor or with the Cisco MDS 9000 18/4-Port Multiservice Module (MSM) or a Cisco MDS 9000 Storage Services Module (SSM) installed in the expansion slot.◦The Cisco MDS 9222i native supervisor, MDS 9000 18/4-Port Multiservice Module, and MDS 9000 Storage Services Module use the SANTap protocol to assist third-party applications in the fabric.◦Higher performance for intelligent fabric applications is provided on the Cisco MDS 9222i using the Cisco MDS 9000 16-Port Storage Services Node (SSN).◦The Cisco MDS 9000 16-Port Storage Services Node initially supports FCIP SAN extension, Cisco SME for tape, and I/O Accelerator (IOA) services and will have other application support in the future. This module has four times the performance of the Cisco MDS 9000 18/4-Port Multiservice Module and has thecapability to host four homogeneous or heterogeneous applications concurrently.●In Service Software Upgrade (ISSU) for Fibre Channel interfaces: Cisco MDS 9222i promotes highserviceability by allowing Cisco MDS 9000 SAN-OS Software to be upgraded while the Fibre Channel ports are carrying traffic.●Intelligent network services: Cisco MDS 9222i uses VSAN technology for hardware-enforced, isolatedenvironments within a single physical fabric, access control lists (ACLs) for hardware-based intelligent frame processing, and advanced traffic management features such as fabric-wide quality of service (QoS) tofacilitate migration from SAN islands to enterprise-wide storage networks.●High-performance ISLs: Cisco MDS 9222i supports up to 16 Fibre Channel links in a single PortChannel.Links can span any port on any module in a chassis for added scalability and resilience. Up to 4095 buffer-to-buffer credits can be assigned to a single Fibre Channel port to extend storage networks over very longdistances.●Comprehensive network security framework: The Cisco MDS 9222i supports RADIUS and TACACS+,Fibre Channel Security Protocol (FC-SP), Secure File Transfer Protocol (SFTP), Secure Shell (SSH) Protocol, Simple Network Management Protocol Version 3 (SNMPv3) implementing AES, VSANs, hardware-enforced zoning, ACLs, and per-VSAN role-based access control (RBAC). Additionally, the Gigabit Ethernet ports offer IP Security (IPsec) authentication, data integrity, and hardware-assisted data encryption for FCIP and iSCSI.●IP Version 6 (IPv6) capable: The Cisco MDS 9222i supports IPv6 as mandated by the U.S. Department ofDefense (DoD), Japan, and China. IPv6 support is provided for FCIP, iSCSI, and management traffic routed in band and out of band.●Sophisticated diagnostics: The Cisco MDS 9222i provides intelligent diagnostics, protocol decoding, andnetwork analysis tools as well as integrated call-home capability for added reliability, faster problemresolution, and reduced service costs.VSANsIdeal for efficient, secure SAN consolidation, 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 maintains 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 complete segregation of traffic and retaining independent control of configuration on a VSAN-by-VSAN basis.IVRIn another step toward deploying efficient, cost-effective, consolidated storage networks, the Cisco MDS 9222i 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. 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.FCIP for Remote SAN ExtensionData distribution, data protection, and business continuance services are significant components of today’s information-centric businesses. The capability to efficiently replicate critical data on a global scale not only helps ensure a higher level of data protection for valuable corporate information, but also increases utilization of backup resources and lowers total cost of storage ownership.●Building on Cisco expertise and knowledge of IP networks, the Cisco MDS 9222i switch uses open-standardsFCIP to break the distance barrier of current Fibre Channel solutions, enabling interconnection of SANislands over extended distances.●The Cisco MDS 9222i dramatically enhances hardware-based FCIP compression performance for both high-bandwidth and low-bandwidth links, providing immediate cost savings for expensive WAN infrastructure. The Cisco MDS 9222i achieves up to a 43:1 compression ratio, with typical ratios of 4:1 to 5:1 over a wide variety of data sources.●The Cisco MDS 9222i supports hardware-based IPsec encryption for secure transmission of sensitive dataover extended distances. Hardware enablement of IPsec helps ensure high throughput. Used together,hardware-based compression and hardware-based encryption provide high-performance, highly secure SAN extension capabilities.I/O Accelerator ServicesThe Cisco MDS 9222i supports I/O accelerator services, a feature set that can significantly improve application performance when storage traffic is extended across long distances. When Fibre Channel and FCIP write acceleration is enabled, WAN throughput is optimized through reduced latency for command acknowledgments. Similarly, the Cisco MDS 9222i supports Fibre Channel and FCIP tape write acceleration, which allows operation at nearly full throughput over WAN links for remote tape backup and restore operations.IOA can be deployed in conjunction with disk data replication solutions to extend the distance between data centers or reduce the effects of latency. IOA can also be used to enable remote tape backup and restore operations without significant throughput degradation. The main features of IOA include:●Fabric service; extends acceleration service as a fabric service to any port in the fabric regardless of where itis attached●Fibre Channel write acceleration (FC-WA) and Fibre Channel tape acceleration (FC-TA)●FCIP write acceleration (FCIP-WA) and FCIP tape acceleration (FCIP-TA)●Fibre Channel and FCIP compression●High availability using PortChannels with acceleration over Fibre Channel and FCIP●Unified solution for disk and tape I/O acceleration over metropolitan area networks (MANs) and WANs●Speed-independent acceleration; accelerates 1/2/4/8/10-Gbps links and consolidates traffic over 8/10-GigabitISLsCisco SMEThe services provided by Cisco SME are mandatory in today’s SANs as a result of enactment of recent regulations that require companies to store and protect data at rest for a specified number of years while publicly disclosing security breaches.●Cisco SME enables data on tapes and VTLs to be compressed, encrypted, and authenticated for centralizedsecurity management and data management and recovery.●Cisco SME is supported in the fixed slot of the Cisco MDS 9222i, and its performance can be scaled up witheither a Cisco MDS 9000 18/4-Port Multiservice Module.●Cisco SME services employ clustering technology to create a highly available solution. The cryptographiccluster formed enhances reliability and availability, provides automated load balancing and failovercapabilities, 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, withsupport for single- and multiple-site deployments. Cisco KMC provides essential features such as keyarchival, secure export and import and translation for distribution, and key shredding.Cisco DMMNatively supported on the Cisco MDS 9222i, 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 mitigate the challenges experienced in migrating data, such as downtime, the need to add data migration software to servers, and the potential for data loss and corruption. By simply enabling the Cisco DMM feature on Cisco MDS 9222i located anywhere in the SAN, data migration can be configured without host agents, without rewiring, with little effect on performance, and without downtime.Platform for Intelligent Fabric ApplicationsThe Cisco MDS 9222i provides an open platform that delivers the intelligence and advanced features required to make multilayer intelligent SANs a reality, including hardware-enabled innovations to host or accelerate applications for data migration, data replication, serverless backup, and network-hosted volume management. Hosting or accelerating these applications in the network can dramatically improve scalability, availability, security, and manageability of the storage environment, resulting in increased utility and lower total cost of ownership (TCO).Integrated Mainframe SupportThe Cisco MDS 9222i 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, Cisco MDS 9222i switches support 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. VSANs 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 intermix techniques. VSANs also eliminate the possibility that a misconfiguration or component failure in one VSAN will affect operation in other VSANs. VSAN-based management access controls simplify partitioning of SAN management responsibilities between mainframe and open systems environments, enhancing security. FICON VSANs can be managed using the integrated Cisco Fabric Manager; the Cisco command-line interface (CLI); or IBM CUP-enabled management tools, including SA/390, Resource Measurement Facility (RMF), and Dynamic Channel Path Management (DCM).Advanced Traffic ManagementThe following advanced traffic-management capabilities are integrated into the Cisco MDS 9222i to simplify deployment and optimization of large-scale fabrics:●Virtual output queuing: Helps ensure line-rate performance on each port, independent of traffic pattern, byeliminating head-of-line blocking●Up to 4095 buffer-to-buffer credits: Can be assigned to an individual port for optimal bandwidth utilizationacross long distances●PortChannels: Allow users to aggregate up to 16 physical ISLs into a single logical bundle, providingoptimized 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 upto 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, to prioritize critical trafficComprehensive Solution for Robust Network SecurityTo address the need for failure-proof security in storage networks, the Cisco MDS 9222i offers an extensive security framework to protect highly sensitive data crossing today’s enterprise networks:●Intelligent packet inspection is provided at the port level, including the application of ACLs for hardwareenforcement of zones, VSANs, and advanced port security features.●Extended zoning capabilities are provided to help ensure that LUNs can be accessed only by specific hosts(LUN zoning), to limit SCSI read commands for a certain zone (read-only zoning), and to restrict broadcasts to only selected zones (broadcast zones).●VSANs offer higher security and greater stability by providing complete isolation among devices that areconnected 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+ to help ensure that only authorized devices access protected storage networks.●Comprehensive IPsec protocol suite delivers secure authentication, data integrity, and hardware-basedencryption for both FCIP and iSCSI deployments.Advanced Diagnostics and Troubleshooting ToolsManagement 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 9222i 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 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.Ease of ManagementTo meet the needs of all users, the Cisco MDS 9222i provides three principal modes of management: the Cisco MDS 9000 Family CLI, Cisco Fabric Manager, and integration with third-party storage management tools.●The Cisco MDS9222i presents a consistent, logical CLI.
