MDS 9124V architecture, with nonblocking arbitration, provides consistent 64-Gbps low-latency performance across all traffic conditions for every Fibre Channel port on the switch.
Fully integrated SAN Analytics:
This feature-rich switch also offers state-of-the-art data traffic analytics and telemetry capabilities that have been built into this next-generation hardware platform. This new state-of-the-art technology couples the next-generation port ASIC with a fully dedicated Network Processing Unit (NPU). Information is extracted by the port ASIC from passing line rate traffic and used by the NPU to calculate performance data on board the switch in real time. Using an industry-leading open telemetry format, the data can be streamed to any analytics visualization platform.
Cisco Dynamic Ingress Rate Limiting (DIRL):
MDS 9124V supports the dynamic ingress rate limiting feature. Using DIRL, the MDS SAN can automatically detect any symptoms of congestion and then dynamically rate limits the congested and slow-drain devices so that adverse effects are not spread to other devices. DIRL dynamically adapts the rate-limiting to suit the traffic profile of the congestion or slow-drain device.
Capital Expenditures (CapEx) savings:
The 64-Gbps ports allow users to deploy them with existing 32- or 16-Gbps transceivers providing investment protection, with an option to upgrade to 64-Gbps transceivers and adapters whenever needed.
High availability:
MDS 9124V switch is designed to provide 99.999% availability. The MDS 9124V switches provides such outstanding availability and reliability by providing redundancy on all major components, such as the power supply and cooling subsystems. Dual power supplies also facilitate redundant power grids.
Reliability:
As part of the standard 64-Gbps Fibre Channel specification, Cisco provides FEC between switch ports and HBA ports on all 64-Gbps Fibre Channel fixed switches. This feature helps ensure any error introduced in flight gets corrected at the receive side of the link. In addition, Cisco extends Buffer-to-Buffer State Change Notification (BBSCN) and buffer-to-buffer credit recovery, which is supported on all Cisco switches between ISL ports, to the fabric ports attached to any end device. Over time, the corruption of receiver-ready messages, known as R_RDY primitives, can lead to a loss of credits, which can eventually cause a link to stop transmitting in one direction. Buffer-to-buffer credit recovery provides for two attached ports to detect and correct this situation.
Next-generation ASIC:
The MDS 9124V Fibre Channel switch is powered by Cisco developed next- generation high-performance 64G ASIC.
Higher scalability:
Increased fabric scalability provides more flexibility for a variety of SAN architectures.
Telemetry:
Fibre Channel and Small Computer System Interface (SCSI) or NVMe headers can be inspected without the need for any external taps or appliances. The resulting metrics can be analyzed on the switch and can additionally be exported using a dedicated 1Gbps Small Form-Factor Pluggable Plus (SFP+) port for telemetry and analytics purposes.
Intelligent services:
Auto-zone, Smart Zoning, slow-drain detection and isolation, Virtual SAN (VSAN) and Inter-VSAN Routing (IVR), and fabric-wide Quality of Service (QoS) enable migration from SAN islands to enterprise-wide storage networks. Traffic encryption is available to meet stringent security requirements.
Overview
Cisco MDS 9124V 64-Gbps 24-Port Fibre Channel switch brings the latest high-performance, low-latency Fibre Channel Storage Area Network (SAN) technology to market. Along with the higher bandwidth, the Cisco MDS 9124V switch supports ease of configuration and management, detailed and in-depth performance insights, and automation capabilities.
The next-generation Cisco MDS 9124V 64-Gbps 24-Port Fibre Channel Switch provides high-speed Fibre Channel connectivity for all-flash arrays and high-performance hosts. This switch offers state-of-the-art analytics and telemetry capabilities built into its next-generation Application- Specific Integrated Circuit (ASIC) chipset. This switch allows seamless transition to Fibre Channel Non-Volatile Memory Express (NVMe/FC) workloads whenever available without any hardware upgrade in the SAN. It empowers small, midsize, and large enterprises that are rapidly deploying cloud-scale applications using extremely dense virtualized servers, providing the benefits of greater bandwidth, scale, and consolidation. Some of the main benefits for a small-scale Storage Area Network (SAN) are automatic zoning, nonblocking forwarding and a single port group of 24 ports. Benefits for a mid- to large-size SAN include higher scale for Fibre Channel control-plane functions, Virtual SANs, fabric login (FLOGI), device alias and name server scale, 24 ports of 64-Gbps non-oversubscribed line-rate ports, bidirectional airflow, and a fixed-form NVMe/FC-ready SAN switch with enhanced Buffer-to-Buffer (B2B) credits and capable of hardware-assisted Fibre Channel link encryption. Large-scale SAN architectures built with SAN core directors can expand 64-Gbps connectivity to the server rack using these switches configured in either switch mode or Network Port Virtualization (NPV) mode. Additionally, the switch supports enhanced diagnostic features such as Inter-Switch Link (ISL) and Host-Bus-Adapter (HBA) diagnostics, remote SFP (Read Diagnostic Parameter) diagnostics, remote port beaconing (Link Cable Beaconing) and advanced reliability features such as link level Forward Error Correction (FEC) with HBA ports.
