IBM Storage Networking SAN24B-6 Switch

Flash-ready performance for evolving storage requirements

Faced with increased competition and the need to deliver differentiated services, 
organizations rely on leading technology to help them expand their businesses and grow 
revenue. IBM b-type Gen 6 Fibre Channel delivers advanced 32 Gbps performance to 
redefine the limits of application performance, and to unleash the full potential of new storage 
technologies.

SAN24B-6 combines market-leading Gen 6 throughput and low latency with an affordable 
switch form factor, making it ideal for small to midsized businesses. Using this switch, 
organizations can build a flash-ready infrastructure that adapts to their expanding business 
requirements. Administrators can achieve optimal bandwidth utilization, high availability, and 
load balancing by combining up to eight inter-switch links (ISLs) in a 256 Gbps framed-based 
trunk. This can be achieved through eight individual 32 Gbps SFP+ ports. 

Moreover, exchange-based dynamic path selection (DPS) optimizes fabric-wide performance 
and load balancing by automatically routing data to the most efficient, available path in the 
fabric. This feature augments ISL Trunking to provide more effective load balancing in certain 
configurations.

To realize the full benefits of flash, organizations will need to transition their 
high-performance, latency-sensitive workloads to flash-based storage with NVMe. SAN24B-6 
is NVMe-ready, allowing organizations to seamlessly integrate IBM b-type Gen 6 Fibre 
Channel networks with next-generation NVMe without a disruptive rip and replace. The 
simplicity and efficiency of NVMe over Fibre Channel enable significant performance gains for 
flash storage. In addition, NVMe enables users to achieve faster application response times 
and harness the performance of solid-state drives for better scalability across virtual data 
centers with flash. Leveraging the efficiency of NVMe over Fibre Channel, combined with the 
high performance and low latency of IBM b-type Gen 6 Fibre Channel, organizations can 
accelerate input/output operations per second (IOPS) to deliver the performance, application 
response time, and scalability needed for next-generation data centers (Figure 2).

Figure 2   DPS augments ISL Trunking to route data efficiently between multiple trunk groups

Rely on the network that delivers always-on business operations 

IBM b-type Gen 5 and Gen 6 technologies leverage a rich heritage of Fibre Channel 
innovation to deliver industry-leading reliability for the world’s most demanding data centers. 
IBM b-type Fabric Vision technology provides a breakthrough hardware and software solution 
that helps organizations simplify monitoring, maximize network availability, and gain insight 
into issues to speed resolution and meet critical service level agreements (SLAs).

VM Insight is the newest feature in Fabric Vision technology, enabling proactive visibility into 
the health and performance of individual VMs with integrated sensors. Using this capability, 
administrators can quickly identify abnormal VM behaviors to facilitate troubleshooting and 
fault isolation, helping to ensure maximum performance and operational stability.

Forward Error Correction (FEC) capabilities further increase resiliency by automatically 
detecting and recovering network transmission errors. To ensure predictable performance 
before deployment, organizations can validate infrastructure with the ClearLink Diagnostics 
and Flow Generator features.

Simplified management and robust network analytics   

Fabric Vision technology provides unprecedented insight and visibility across the storage 
network, with powerful integrated monitoring, management, and diagnostic capabilities. 
These innovative features enable administrators to avoid problems before they impact 
operations, helping organizations meet SLAs. Fabric Vision technology includes these 
features:

򐂰

VM Insight: Seamlessly monitors VM performance throughout a storage fabric with 
standards-based, end-to-end VM tagging. Administrators can quickly determine the 
source of VM/application performance anomalies, as well as provision and fine-tune the 
infrastructure based on VM/application requirements to meet service-level objectives.

򐂰

Monitoring and Alerting Policy Suite (MAPS): Leverages prebuilt, rule-/policy-based 
templates within MAPS to simplify fabric-wide threshold configuration, monitoring, and 
alerting. Administrators can configure the entire fabric (or multiple fabrics) at one time 
using common rules and policies, or customize policies for specific ports or switch 
elements. With Flow Vision and VM Insight, administrators set thresholds for VM flow 
metrics in MAPS policies to be notified of VM performance degradation.

򐂰

Fabric Performance Impact (FPI) Monitoring: Uses predefined MAPS policies to 
automatically detect and alert administrators to different latency severity levels, and to 
identify slow-drain devices that could affect network performance. This feature identifies 
various latency severity levels, pinpointing exactly which devices are causing or are 
affected by a bottlenecked port, and quarantines automatically slow-drain devices to 
prevent buffer credit starvation.

򐂰

Dashboards: Provides integrated dashboards that display an overall storage area 
network (SAN) health view, along with details about out-of-range conditions, to help 
administrators easily identify trends and quickly pinpoint issues occurring on a switch or in 
a fabric.

򐂰

Configuration and Operational Monitoring Policy Automation Services Suite 
(COMPASS):
 Simplifies deployment, safeguards consistency, and increases operational 
efficiencies of larger environments with automated switch and fabric configuration 
services. Administrators can configure a template or adopt an existing configuration to 
seamlessly deploy a configuration across the fabric. In addition, they can ensure that 
settings do not drift over time with COMPASS configuration and policy violation monitoring 
within IBM Network Advisor dashboards.

򐂰

ClearLink Diagnostics: Ensures optical and signal integrity for Fibre Channel optics and 
cables, simplifying deployment and support of high-performance fabrics. ClearLink 
Diagnostic Port (D_Port) is an advanced capability of Fibre Channel platforms.

򐂰

Flow Vision: Enables administrators to identify, monitor and analyze specific application 
flows in order to simplify troubleshooting, maximize performance, avoid congestion, and 
optimize resources. Flow Vision includes these features:

– Flow Monitor: Provides comprehensive visibility, automatically learns and 

nondisruptively monitors flow performance. Administrators can monitor all flows from a 
specific host to multiple targets or logical unit numbers (LUNs), from multiple hosts to a 
specific target/LUN, or across a specific ISL. Additionally, they can perform LUN-level 
monitoring of specific frame types to identify resource contention or congestion that is 
affecting application performance. With VM Insight, administrators can monitor network 
throughput statistics for each VM.

– Flow Learning: Enables administrators to nondisruptively discover all flows that go to 

or come from a specific host port or a storage port, or traverse ISLs/inter-fabric links 
(IFLs) or Fibre Channel over IP (FCIP) tunnels, to monitor fabric-wide application 
performance. In addition, administrators can discover top and bottom 
bandwidth-consuming devices and manage capacity planning.

– Flow Generator: Provides a built-in traffic generator for pretesting and validating your 

infrastructure for robustness, including route verification and integrity of optics, paths 
and connectors, cables, ports, back-end connections, and ISLs, before deploying 
applications.

– Flow Mirroring: Provides the ability to nondisruptively create copies of specific 

application and data flows or frame types that can be captured for in-depth analysis.

򐂰

Forward Error Correction (FEC): Enables recovery from bit errors in device connections 
and ISLs, enhancing transmission reliability and performance.

򐂰

Credit Loss Recovery: Helps overcome performance degradation and congestion due to 
buffer credit loss.

IBM Network Advisor

IBM Network Advisor simplifies Gen 6 Fibre Channel management and helps organizations 
proactively diagnose and resolve issues to maximize uptime, increase operational efficiency, 
and reduce costs. The wizard-driven interface dramatically reduces deployment and 
configuration times by allowing fabrics, switches, and ports to be managed as groups. 
Customizable dashboards graphically display performance and health indicators out of the 
box, including all data captured using Fabric Vision technology. 

To accelerate troubleshooting, administrators can use dashboard playback to quickly review 
past events and identify problems in the fabric. Dashboards and reports can be also 
configured to show only the most relevant data, enabling administrators to more efficiently 
prioritize their actions and maintain network performance.

Access Gateway mode

SAN24B-6 can be deployed as a full-fabric switch or as an Access Gateway, which simplifies 
fabric topologies and heterogeneous fabric connectivity (the default mode setting is a switch). 
Access Gateway mode utilizes N_Port ID Virtualization (NPIV) switch standards to present 
physical and virtual servers directly to the core of SAN fabrics. This configuration makes a 
switch in Access Gateway mode transparent to the SAN fabric, greatly reducing management 
of the overall storage network edge. SAN24B-6 in Access Gateway mode can connect 
servers to NPIV-enabled SAN fabrics.

Organizations can easily enable Access Gateway mode via IBM Network Advisor or a 
command-line interface (CLI). Access Gateway mode includes these key benefits:

򐂰

Improved scalability for large or rapidly growing server and virtual server environments

򐂰

Reduced management of the network edge because Access Gateway does not have a 
domain identity and appears transparent to the core fabric
