20. ClearLink diagnostics Buffer Credit Recovery
IO Insight and VM Insight Features Added for Fabric Vision of the 32 Gbit/s Platform Switch
Degraded storage I/O performance can be automatically detected and can be integrated with network monitoring.
Policy-based automatic monitoring and alerting can be simplified.
Diagnostics of cables and optical modules can simplify the deployment and support of large Fabric architectures.
All key information can be displayed on a tailored health status and performance dashboard.
The performance of specific flow or frame type can be identified, monitored, and analyzed.

The standard-based E2E VM tagging can be used to seamlessly monitor the VM performance throughout the storage architecture.
Severe delay alerts can be quickly detected and released to help find out "slow drain" devices.
Bit errors can be detected and recovered, eliminating the demand for retransmission.
The flow control buffer credit lost at the VC level can be automatically recovered, improving availability.
SAN configuration can be simplified and consistency in operational behavior can be maintained.

22. Monitoring and Alerting Policy Suite
MAPS Technology Based on Threshold Monitoring and Alerting
The switch has multiple built-in predefined policies. Best practices for monitoring over the past 20 years in the industry can be deployed by several simple operations.
Predefined group
Port groups such as F_Port, E_Port, initiator port, and target port are predefined.
Hardware groups such as fan, power supply, temperature sensor, and optical module are predefined.
Self-defined groups are supported.
MAPS
Monitoring and Alerting Policy Suite
Predefined policy, rule, and action
Radical, moderate, and conservative policies are predefined.
Over 200 rules (thresholds) are included in each policy according to historical best practices.
Possible actions such as SNMP, , RASLOG, and FENCE are predefined for different rules. After an action is triggered, the system executes the action.
Intuitive report
The switch health status report is displayed on the CLI and factors affecting switch health can be found out.
With BNA, the report can be graphically displayed.

23. NVMe over Fabrics – The Next Revolutionary Storage Technology
NVMe will use its unique performance advantages to provide all-flash arrays with performance which SCSI can never achieve.
Gen 6 switches have ASIC chips tailored for NVMe traffic monitoring.
NVMe over Fabric will see fierce competition. The NVMe based on Fibre Channel is exclusively designed for the storage area network.

24. UltraScale ICL Technology (Applicable to SNS5608 and SNS5604)
Simple and scalable Core-Edge architecture
– The architecture supports a maximum of 12 chassis.
Higher port density and bandwidth
– Up to 4608 ports of 32 Gbit/s are supported without ISL.
– 12 domains provide aggregate bandwidth over 144 Tbit/s.
Fewer chassis and cables
– The Core-Edge architecture built by ICL requires a maximum of 12 chassis and 128 cables.
Not occupying common service ports, ensuring port usage
Gen 6 ICL has the following advantages over Gen5 ICL:
The ICL port bandwidth of a Gen 6 director is twice that of a Gen 5 director.
The ICL port of a Gen 6 director can interconnect with that of a Gen 5 director, cutting investment.
Enterprise-level ICL licenses are no longer configured for Gen 6 directors, cutting investment.
The Gen 6 director supports the LC port with a transmission distance of 2 km, and the Gen 5 director supports the MPO port. The LC port is more easily deployed than the MPO port.

25. Three SNS3664 Switches Form the Full Mesh Architecture by QSFP Cascading
QSFP ports can be used to set up an ISL between two SNS3664 switches, so that all SFP ports are released to connect terminal devices.
Three SNS3664 switches form the Full Mesh architecture to provide 144 (48 x 3) ports for terminal devices. The overload ratio is 3:1 in the worst situation.
Eight links in 2 QSFP optical modules can constitute 256 Gbit/s trunking.
Users build a high-performance and high-density fiber optic network using simplified cabling in a small area.
ISL 256 Gbit/s trunk
The Full Mesh architecture formed by SNS2248 switches can provide a maximum of 96 available ports.
The number of available ports increases by 50%.
