Architecture and key components

This section describes the architecture and key components of the IBM Storage Networking SAN50C-R.

VSANs

VSANs are ideal for efficient, secure SAN consolidation, enabling more efficient storage network usage 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.

IVR

In another step toward deploying efficient, cost-effective, and consolidated storage networks, the IBM Storage Networking SAN50C-R switch 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, maintaining fabric stability and availability.

IVR is one of the feature enhancements that are provided with the Enterprise advanced software package. It eliminates the need for external routing appliances, greatly increasing routing scalability while delivering line-rate routing performance, simplifying management, and eliminating the challenges that are associated with maintaining separate systems. Deploying IVR means lower total cost of SAN ownership.

FCIP for remote SAN extension

Data 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 the usage of backup resources and lowers total cost of storage ownership.

• Building on expertise and knowledge of IP networks, the IBM Storage Networking SAN50C-R switch uses open-standards FCIP to break the distance barrier of current Fibre Channel solutions, enabling the interconnection of SAN islands over extended distances.
• The IBM Storage Networking SAN50C-R switch dramatically enhances hardware-based FCIP compression performance for both high-bandwidth and low-bandwidth links, providing immediate cost savings for expensive WAN infrastructure. The IBM Storage Networking SAN50C-R 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 IBM Storage Networking SAN50C-R switch supports hardware-based IPSec encryption for secure transmission of sensitive data over 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 Acceleration services

The IBM Storage Networking SAN50C-R switch supports I/O Acceleration (IOA) services, an advanced software package that can significantly improve application performance when storage traffic is extended across long distances. When Fibre Channel and FCIP write acceleration are enabled, WAN throughput is optimized through reduced latency for command acknowledgments. Similarly, the IBM Storage Networking SAN50C-R switch 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 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. Here are the main features of IOA:

• Extension of the acceleration service as a fabric service to any port in the fabric, regardless of where it is 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 that accelerates 2/4/8/16-Gbps FC links and consolidates traffic over 8/16 Gigabit ISLs

Mainframe support

IBM Storage Networking SAN50C-R is mainframe-ready and supports IBM zSeries FICON and Linux environments provided with the Mainframe advanced software package. Qualified by IBM for attachment to all FICON-enabled devices in an IBM zSeries operating environment, IBM Storage Networking SAN50C-R switches support transport of the FICON protocol in both cascaded and noncascaded 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 that is 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 standard Data Center Network Manager (DCNM), the command-line interface (CLI), or CUP-enabled management tools, including SA/390, Resource Measurement Facility (RMF), and Dynamic Channel Path Management (DCM).

The Mainframe package is required for all IBM Storage Networking SAN50C-R integrated FICON channel extension features. In combination with SAN extension capabilities, it enables FICON tape read and write acceleration.

Advanced traffic management

The following advanced traffic-management capabilities are integrated as standard on the IBM Storage Networking SAN50C-R switch:

• Virtual output queue (VOQ): Helps ensure line-rate performance on each port, independent of traffic pattern, by eliminating head-of-line blocking.
• PortChannels: Allow users to aggregate up to 16 physical ISLs into a single logical bundle, providing optimized bandwidth usage 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 during a module failure.
• Fabric Shortest Path First (FSPF)-based multipathing: Provides the intelligence to load-balance across up to 16 equal-cost paths and, during a switch failure, dynamically reroute traffic.

The following extra advanced traffic-management capabilities are available on the IBM Storage Networking SAN50C-R switch with the optional Enterprise advanced software package to simplify deployment and optimization of large-scale fabrics:

• Up to 256 buffer-to-buffer credits: Can be assigned to an individual port for optimal bandwidth usage across long distances.
• QoS: Can be used to manage bandwidth and control latency to prioritize critical traffic for specific applications.
• IVR: Eliminates the need for external routing appliances, greatly increasing routing scalability while delivering line-rate routing performance, simplifying management, and eliminating the challenges that are associated with maintaining separate systems.
• SCSI flow statistics: Collects logical unit number (LUN)-level SCSI flow statistics, including read, write, and error statistics, for any combination of initiators and targets.

Comprehensive solution for robust network security

To address the need for failure-proof security in storage networks, the IBM Storage Networking SAN50C-R switch includes as standard an extensive security framework to protect highly sensitive data crossing today’s enterprise networks:

• When the Smart Zoning feature is enabled, IBM Storage Networking c-type Family fabrics provision the hardware access control entries that are specified by the zone set more efficiently. Doing so avoids the superfluous entries that allow servers (initiators) to talk to other servers, or allow storage devices (targets) to talk to other storage devices.

This feature makes larger zones with multiple initiators and multiple targets feasible without excessive consumption of hardware resources. Thus, smart zones can correspond to applications, application clusters, hypervisor clusters, or other data center entities, saving the time that administrators previously spent creating many small zones, and enabling the automation of zoning tasks.

• Intelligent packet inspection is provided at the port level, including the application of ACLs for hardware enforcement 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).

The following additional advanced security-management capabilities are available on the IBM Storage Networking SAN50C-R switch with the Enterprise advanced software package to further help ensure the security of large-scale fabrics:

• Switch-to-switch and host-to-switch authentication helps eliminate disruptions that might occur because of unauthorized devices connecting to a large enterprise fabric.
• Port security locks down the mapping of an entity to a switch port to help ensure that SAN security is not compromised by connection of unauthorized devices to a switch port.
• VSAN-based access control allows customers to define roles in which the scope of the roles is limited to certain VSANs.
• FC-SP provides switch-switch and host-switch Diffie-Hellman Challenge Handshake Authentication Protocol (DH-CHAP) authentication that supports 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-based encryption for both FCIP and iSCSI deployments.
• Digital certificates are issued by a trusted third party and are used as electronic passports to prove the identity of certificate owners.
• Fabric binding for open systems helps ensure that the ISLs are enabled only between switches that are authorized in the fabric binding configuration.

Advanced diagnostic and troubleshooting tools

Management of large-scale storage networks requires proactive diagnostic tools to verify connectivity and route latency, and mechanisms for capturing and analyzing traffic. The IBM Storage Networking c-type Family integrates the industry’s most advanced analysis and diagnostic tools, which are included as standard on the IBM Storage Networking SAN50C-R switch.

The power-on self-test (POST) and Generic Online Diagnostics (GOLD) provide proactive health monitoring. The IBM Storage Networking SAN50C-R switch implements diagnostic capabilities, such as Fibre Channel traceroute to identify the exact path and timing of flows, and Switched Port Analyzer (SPAN) to intelligently capture network traffic.

After traffic is captured, it can be analyzed with Fabric Analyzer, which is an embedded Fibre Channel analyzer. Comprehensive port-based and flow-based statistics facilitate sophisticated performance analysis and service level agreement (SLA) accounting. With the IBM Storage Networking c-type Family, IBM delivers a comprehensive tool set for troubleshooting and analysis of storage networks.

Ease of management

To meet the needs of all users, IBM Storage Networking SAN50C-R switch provides three principal modes of management: CLI, DCNM, and integration with third-party storage management tools.

The IBM Storage Networking SAN50C-R switch presents a consistent, logical CLI. Adhering to the syntax of the widely known IOS Software CLI, which is easy to learn and delivers broad management capabilities. The CLI is an efficient and direct interface that provides optimal capabilities to administrators in enterprise environments.

Data Center Network Manager (DCNM) for SAN is an application that simplifies management across multiple switches and converged fabrics. It provides robust features to meet the routing, switching, and storage administration needs of present and future virtualized data centers, streamlines provisioning of the unified fabric, and proactively monitors SAN components. DCNM SAN can be used independently or with third-party management applications.

The solution is designed to scale to large enterprise deployments through a scale-out server architecture with automated failover capability. These capabilities provide a resilient management system that centralizes infrastructure and path monitoring across geographically dispersed data centers. DCNM SAN base management functions are available at no additional charge, whereas advanced features are unlocked with the DCNM SAN Advanced license. The DCNM SAN application can be installed on Linux and Microsoft Windows operating systems and supports both PostgreSQL and Oracle databases.

Advanced software packages

The IBM Storage Networking SAN50C-R switch can be further enhanced through additional optional licensed software packages that offer advanced intelligence and functions (summarized in Tables 1 and 2). The following software packages are available:

• Enterprise package: This package includes a set of traffic engineering and advanced security features, such as extended-distance buffer-to-buffer (B2B) credits, IVR, QoS, switch-to-switch and host-to-switch authentication, LUN zoning, and read-only zones, which are recommended for enterprise SANs.
• DCNM SAN Advanced: DCNM is an easy-to-use application that simplifies management across multiple switches and fabrics. Focused on supporting efficient operations and management of virtual machine-aware fabrics, it provides a robust framework and rich feature set that meets the routing, switching, and storage administration needs of present and future virtualized data centers. DCNM streamlines provisioning of the unified fabric and proactively monitors the SAN components.
• IOA Services package: The IBM Storage Networking SAN50C-R switch supports IOA services, which is an advanced software package 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.
• Mainframe package: This package is a comprehensive collection of features required for using the IBM Storage Networking c-type Series switches in mainframe storage networks. These features include FICON protocol, FICON tape acceleration (read and write), CUP management, switch cascading, fabric binding, and intermixing.
