Cisco MDS 9148T 32G FC switch, w/ 48 active ports + 48x32G SW Optics, 4 Fans, 2 PSUs, Port Side Intake DS-C9148T-48PITK9

Part Number: DS-C9148T-48PITK9

Main features

The main features of the Cisco MDS 9148T 32-Gbps 48-Port Fibre Channel Switch include:

●   High performance: MDS 9148T architecture, with centralized nonblocking arbitration, provides consistent 32-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 SAN analytics and telemetry capabilities that have been built into this next-generation hardware platform. This new state-of-art technology couples the next-generation port ASIC with a fully dedicated Network Processing Unit designed to complete analytics calculations in real time on the 32-Gbps line card. The telemetry data extracted from the inspection of the frame headers are calculated on board (within the switch) and, using an industry-leading open format, can be streamed to any analytics-visualization platform.

●   Capital Expenditures (CapEx) savings: The 32-Gbps ports allow users to deploy them with existing 16- or 8-Gbps transceivers provide investment protection with an option to upgrade to 32-Gbps transceivers and adapters whenever needed.

●   High availability: MDS 9148T switches continue to provide the same outstanding availability and reliability as the previous-generation Cisco MDS 9000 Family switches by providing redundancy on all major components such as the power supply and fan. Dual power supplies also facilitate redundant power grids. In addition, port-channel link members can be striped across the three 16-port port groups, thus providing additional high availability.

●   Reliability: As part of the standard 32-Gbps Fibre Channel specification, Cisco provides FEC between switch ports and HBA ports on all 32-Gbps Fibre Channel fixed switches. This feature helps ensure any error introduced in flight gets corrected before it reaches the device side. 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.

●   Growth in small increments: The MDS 9148T Fibre Channel switch provides an option to deploy as few as twenty-four 32-Gbps Fibre Channel ports in the entry-level variant, which can grow in increments of 8 ports to up to 48 ports. This setup allows four possible configurations of 24, 32, 40, and 48 ports.

●   Next-generation ASIC: The MDS 9148T Fibre Channel switch is powered by the same high-performance 32-Gbps Cisco ASIC that powers the Cisco MDS 32-Gbps Fibre Channel product portfolio.

●   Higher scalability: Increased fabric scalability provides more flexibility for a variety of SAN architectures.

●   Telemetry: Fibre Channel and Small Computer System Interface (SCSI) headers can be inspected without the need for any external taps or appliances. The resulting metrics can be analyzed on the switch and also exported using a dedicated 1- or 10-Gbps 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 fabricwide Quality of Service (QoS) enable migration from SAN islands to enterprise.wide storage networks. Traffic encryption is optionally available to meet stringent security requirements.

●   Sophisticated diagnostics: The MDS 9148T provides intelligent diagnostics tools such as ISL diagnostics, HBA diagnostics, read diagnostic parameters, Switched Port Analyzer (SPAN), Integrated Cisco Call Home capability, and an Online Health Management System for greater reliability, faster problem resolution, and reduced service costs.

●   Virtual-machine awareness: The MDS 9148T provides visibility into all virtual machines that are accessing the storage LUNs in the fabric. This feature is available through HBAs capable of priority tagging the Virtual Machine Identifier (VMID) on every Fibre Channel frame. Virtual-machine awareness can be extended to intelligent fabric services such as analytics1 to visualize performance of every flow originating from each virtual machine in the fabric.

●   Programmable fabric: The MDS 9148T provides powerful Representational State Transfer (REST) and Cisco NX-API capabilities to enable flexible and rapid programming of utilities for the SAN.

●   Single-pane management: You can provision, manage, monitor, and troubleshoot the MDS 9148T using Cisco Data Center Network Manager (DCNM), which currently manages the entire suite of Cisco data center products.

●   Secure-boot and anti-counterfeiting technology: The MDS 9148T uses onboard hardware that protects the entire system from malicious attacks by securing access to critical components such as the bootloader, system image loader, and Joint Test Action Group (JTAG) interface.
