Overview of Cisco MDS 9148T Fibre Channel
Switch
The Cisco MDS 9148T switch has 48 x 4/8/16/32-Gbps multispeed ports and is a powerful and compact
1-rack unit (1RU) SAN fabric switch. This switch has the following major features:
• Provides consistent 32-Gbps quality performance for every Fibre Channel port on the switch.
• Provides availability and reliability similar to the previous generations of the Cisco MDS9000 Series
switches. Additionally, port-channel link members can be used across the three 16-port port groups
providing additional high availability.
• Provides minimum configuration option of twenty four 32-Gbps Fibre Channel ports in the base variant,
which can be enabled in increments of 8 ports to up to 48 ports. This allows four possible configurations
of 24, 32, 40, and 48 ports.
• Supports enterprise-class features, such as Auto Zone, Smart Zoning, Slow Drain Detection and Isolation,
Virtual SAN (VSAN) and Inter-VSAN routing (IVR), and migration from fabricwide Quality of Service
(QoS) from SAN islands to enterprisewide storage networks.
• Provides intelligent diagnostics tools such as Inter-Switch Link (ISL) diagnostics, HBA diagnostics with
leading HBA vendors, read diagnostic parameters, protocol decoding, network analysis tools, and
integrated Cisco Call Home.
• Supports the Virtual Machine Identifier (VMID) feature that provides visibility into virtual machines
that are accessing the storage devices in the fabric.
• Supports Representational State Transfer (REST) and Cisco NX-API capabilities.
• Supports onboard hardware that protects the switch from malicious attacks by securing access to critical
components such as the bootloader, system image loader, and Joint Test Action Group (JTAG) interface.
