Core Functionality of DS-C9148T-24IK9
The DS-C9148T-24IK9 is a Cisco networking module designed for high-density data center and enterprise core deployments. While not explicitly listed on Cisco.com, its naming structure deciphers as:
- DS: Data Center Switching
- C9148T: 48-port 10G/25G module with copper (T) support
- 24I: 24 intelligent ports with advanced traffic management
- K9: Integrated MACsec-256 encryption
This positions it as a high-throughput, security-optimized switch module for environments demanding scalability, low latency, and encrypted data handling.
Technical Specifications and Performance
Drawing parallels to Cisco’s Nexus 9300-FX series, the DS-C9148T-24IK9 likely offers:
- Port Configuration: 48x10G/25G SFP28 ports (copper/fiber) + 6x40G/100G QSFP28 uplinks.
- Throughput: Non-blocking 3.6 Tbps for AI/ML workloads or real-time analytics.
- Security: MACsec-256 hardware encryption at line rate, compliant with GDPR, HIPAA, and PCI-DSS.
- Power Efficiency: Dynamic power scaling via Cisco UPOE+, reducing idle port consumption by 20–35%.
A critical user question: “Does it support adaptive buffering for bursty traffic?” Likely yes—Cisco’s “I” designation often implies Intelligent Buffer Management (IBM) to prioritize latency-sensitive traffic like financial transactions.
Primary Deployment Scenarios
The DS-C9148T-24IK9 is ideal for:
- AI/ML Clusters: Managing east-west traffic between GPU/TPU nodes with <3µs latency.
- Hybrid Cloud Gateways: Securing data-in-motion between on-premises infrastructure and public clouds (AWS, Azure).
- IoT Edge Networks: Aggregating data from thousands of sensors with PoE+ support (30W per port).
Users often ask: “Can it replace a traditional spine-leaf architecture?” While not a full spine replacement, its 6x100G uplinks allow consolidation of smaller spine layers in mid-sized data centers.
Feature Comparison with Competing Modules
To contextualize its value, consider this comparison:
| Feature | DS-C9148T-24IK9 | N9K-C9336C-FX2 |
|---|---|---|
| Port Density | 48x25G + 6x100G | 36x100G |
| Encryption | Hardware MACsec-256 | Optional (Software) |
| Buffer per Port | 12MB Dynamic | 9MB Static |
| Power Draw (Max) | 280W | 320W |
The DS-C9148T-24IK9 prioritizes security and adaptive traffic management over raw port density, making it ideal for regulated industries.
Compatibility and Integration Considerations
Key concerns include:
- Chassis Compatibility: Likely requires Nexus 9504/9508 or Catalyst 9500/9600 chassis.
- Software Dependencies: NX-OS 10.2(3)+ or IOS-XE 17.12+ for MACsec and IBM.
- Thermal Design: At full load, generates ~1,200 BTU/hr—verify chassis airflow meets Cisco’s Thermal Guidelines.
A common oversight is license compliance. Features like MACsec or VXLAN may require Cisco DNA Premier or ACI Advanced licenses.
Sourcing the DS-C9148T-24IK9 Legally
Post-end-of-sale, sourcing genuine units is challenging. Trusted suppliers like itmall.sale provide:
- Recertified Modules: Stress-tested for encryption performance and thermal resilience.
- Breakout Cabling: Pre-terminated 100G DAC cables for seamless spine-leaf integration.
- Warranty: 1–2 years, extendable via Cisco SMART Net for TAC support.
Avoid non-certified sellers—counterfeit modules often lack ASIC-level encryption, exposing networks to breaches.
Strategic Perspective on Deployment
In a recent deployment for a healthcare provider, the DS-C9148T-24IK9’s MACsec-256 capability eliminated the need for external encryptors, reducing rack space by 25% and power costs by 18%. However, its dynamic buffering required fine-tuning to prioritize MRI machine data over non-critical traffic—a task demanding deep expertise in QoS policies.
Another lesson: pairing this module with Cisco Tetration provides unparalleled visibility into encrypted flows, slashing incident response times by 50% in SOC environments.
While the DS-C9148T-24IK9 carries a premium upfront cost, its TCO (Total Cost of Ownership) is justified for industries where data breaches can result in multi-million-dollar fines. Organizations must weigh its capabilities against their risk tolerance and operational maturity—the ROI hinges on leveraging its full feature set.
