Ultimate Review of MikroTik CRS317 1G 16S+RM Cloud Router Switch
The MikroTik CRS317 1G 16S+RM serves as a premier rackmount layer three manageable switch tailored for high performance enterprise networks and data centers. This device offers exceptional port density and wire speed connectivity to deliver reliable core switching operations. Here is a comprehensive overview of this networking asset to help optimize your infrastructure deployment.
Key Hardware Specifications
This Cloud Router Switch is built to deliver high speed data distribution across demanding network architectures.
- Core Processor: 98DX8216 dual core CPU running at 800 MHz.
- Memory Capacity: 1 GB RAM paired with 16 MB storage flash memory.
- High Speed Ports: Sixteen 10G SFP+ interfaces for high bandwidth connectivity.
- Management Ports: Single Gigabit Ethernet port for out of band configuration.
- Power Supply: Dual redundant hot swappable power supplies for continuous operation.
- Cooling System: Dual automatic fans with passive cooling mode for low traffic environments.
Performance and Layer 3 Hardware Offloading
The foundation of this switch is a powerful Marvell Prestera DX packet processing chip. This hardware integration allows the device to achieve full wire speed performance across all sixteen ports simultaneously
While traditional switches experience severe performance degradation when enabling routing features, this model utilizes Layer 3 Hardware Offloading. This feature processes routing decisions directly on the switch silicon instead of taxing the central processing unit
The dual core CPU remains free to manage background system processes, link aggregation protocols, and monitoring tools. This results in ultra low latency, maximum throughput, and reliable packet forwarding even under full network load.
Ideal Deployment Use Cases
Mid Size Enterprise Core
The sixteen SFP+ ports make it an ideal central core switch to connect multiple access switches across an office building.
Server Room Aggregation
It provides a high density aggregation point for connecting top of rack servers directly to the main network infrastructure.
Fiber To The Home Distribution
Service providers can utilize the optical ports to distribute high speed fiber connections to localized distribution nodes.
Dual Boot Flexibility with SwOS and RouterOS
A key feature of this hardware is the dual boot capability, giving administrators the freedom to choose their preferred software environment
Selecting SwOS boots a simplified operating system focused entirely on switch specific features like port forwarding, MAC filtering, VLAN configuration, and bandwidth limitation.
Selecting RouterOS unlocks a full comprehensive routing suite capable of handling complex firewall rules, dynamic routing protocols, and advanced traffic shaping.
Enterprise Redundancy Features
Network downtime is mitigated through robust hardware engineering. The inclusion of dual hot swappable power supplies ensures the switch remains active even if one power source fails.
The cooling architecture features smart fans that only activate when the temperature rises, reducing noise and extending the lifespan of mechanical components. The structural rackmount ears allow secure installation into any standard server enclosure.
