Common Use Cases for DEM-314GT

The DEM-314GT is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.

  • Server Uplink — 10G/25G server-to-leaf uplink — pair with matching DAC or AOC at the host NIC to avoid optic mismatch.
  • DCI (Data Center Interconnect) — Inter-DC routing or aggregation. LR4/LR8 transceivers for 10–80 km, ER4 for 40 km, ZR4 for coherent long-haul.
  • Campus Distribution — Catalyst-class campus distribution between IDF and MDF closets. PoE+ where wireless APs and IP phones share infrastructure.
  • Branch / Edge — Smaller form-factor switches and routers for branch sites. SD-WAN-compatible or static-VPN-attached as the architecture dictates.

New, Bulk, or Refurbished — Choosing Your Tier

Pro Disk Network offers the DEM-314GT across three procurement tiers. Each tier is fully functional and warranted; the choice comes down to budget, warranty length, and whether the deployment is production-critical or capacity-expansion.

Pro Disk Network Buyer’s Guide: Networking Devices

Optic Coding, Vendor Lock-In, and Multi-Vendor Compatibility

For Cisco IOS, IOS-XE, and NX-OS switches, the DEM-314GT works out-of-box if coded for Cisco; for Aruba ArubaOS-CX, code for HPE/Aruba; for Juniper Junos, code for Juniper. Pro Disk Network confirms the target vendor coding at order time and applies it before shipping. Misordered coding can be flashed in the field but the lead time is longer than ordering correctly the first time.

Bandwidth Sizing for Spine-Leaf, EVPN-VXLAN, and Hyperconverged Storage

Document optic types and bandwidth in your network drawings: SR-SR for intra-rack, LR-LR for inter-rack and DCI, ZR4 for long-haul coherent. Mismatched optic-distance ratings is the most common cause of intermittent link errors that look like cable problems but aren't.
