DS-C9148T-24PETK9 Description
Cisco DS-C9148T-24PETK9 is a 32-Gbps Fibre Channel SAN switch in the Cisco MDS 9148T family, delivering 48 physical FC ports with 24 ports active by license and seamless expansion to 48 through port-on-demand. The 9148T platform provides line-rate 32G performance with autosensing 4/8/16/32-Gbps FC, native NVMe/FC support, hardware-assisted SAN Analytics, and enterprise-grade resiliency with redundant hot-swappable power and fans. Built on Cisco NX-OS and managed through Cisco Nexus Dashboard Fabric Controller (formerly DCNM), the 9148T series simplifies day-2 operations with intelligent telemetry, streaming analytics, and consistent policy across modern flash arrays, mission-critical databases, and virtualized workloads.

Model Selection Guide – DS-C9148T-24PETK9
|
Common requirement scenario |
Suitable? Recommendation |
|---|---|
|
Build a new 32G FC access/edge for all-flash arrays |
Suitable. 48 physical FC ports with 24 active (license to expand) deliver predictable low-latency, line-rate performance for AFA and high-IOPS hosts. |
|
Start with 24 ports and scale later |
Highly suitable. Base license enables 24 ports; expand in steps via POD licenses to 32/40/48 without hardware changes. |
|
Plan to adopt NVMe/FC |
Suitable. NVMe/FC-ready design allows seamless transition while coexisting with SCSI workloads. |
|
Need built-in visibility & telemetry |
Suitable. Hardware-assisted SAN analytics, slow-drain detection, and streaming telemetry simplify troubleshooting and capacity planning. |
|
Dense virtualization and per-VM visibility |
Suitable. VMID awareness plus analytics helps pinpoint per-flow or per-VM performance issues. |
|
Layered design with NPIV/NPV to simplify ops |
Suitable. Use as NPIV core with NPV edge to grow host ports over time with minimal management overhead; Auto/Smart Zoning reduces manual work. |
|
Strict HA requirements (power/fans/links) |
Suitable. Redundant hot-swappable PSUs/fans; port-channels across port groups improve fabric resiliency for 24×7 environments. |
|
Data-center airflow policies (hot/cold aisle) |
Suitable. Order intake (red) or exhaust (blue) airflow options to match rack cooling direction. |
|
Reuse existing 8G/16G optics first |
Suitable. 32G ports are autosensing; you can deploy with existing 8G/16G optics/HBAs and upgrade later to 32G. |
|
Require link robustness (FEC, credit recovery) |
Suitable. Supports FEC and buffer-to-buffer credit recovery mechanisms to mitigate errors and credit loss. |
|
Need stronger security / fabric isolation |
Suitable. VSANs, role-based access, FC-SP (DH-CHAP), and optional link encryption help meet stringent security requirements. |
|
Unified management & automation |
Suitable. NX-OS CLI, REST/NX-API, Python/Ansible; managed via Cisco NDFC/DCNM for single-pane operations. |
|
Limited to 1RU, careful with power draw |
Suitable. Compact 1RU chassis; dual PSU options fit common power grids and rack densities. |
|
Need more than 48 FC ports or very long-distance links |
Not ideal. Consider higher-port models (e.g., 96-port MDS 9396T/9396V) or director-class for large scale/long-haul B2B credit needs. |
