Cisco Nexus 3064-T vs Nexus 93108TC-FX3
The N3K-C3064TQ-10GT is an end-of-life 10GBASE-T copper ToR switch; the Nexus 93108TC-FX3 (N9K-C93108TC-FX3) is its modern 10GBASE-T replacement with 100G uplinks and far higher capacity. For any copper-based server refresh, migrate to the 93108TC-FX3 for 100G uplinks, MACsec, and current NX-OS/ACI support.

Choose Cisco Nexus 3064-T if
Keep the 3064-T only as a short-term bridge in an existing 10GBASE-T rack where 40G uplinks are still adequate and you accept end-of-support risk; it is not appropriate for new buys.
Choose Cisco Nexus 93108TC-FX3 if
Choose the 93108TC-FX3 for any copper 10GBASE-T server refresh that needs 100G uplinks, MACsec, ACI readiness, and a supportable platform.
Verdict
Migrate from the Nexus 3064-T to the 93108TC-FX3. Both keep the same 48-port 10GBASE-T copper access for existing cabling, but the FX3 nearly doubles switching capacity, adds 100G uplinks and MACsec, and remains under support. Retain 3064-T units only briefly while you finish the migration.
Frequently asked questions
Is the Cisco Nexus 3064-T end of life?
Yes. The N3K-C3064TQ-10GT has passed end-of-sale and end-of-support milestones and should be migrated rather than expanded.
Does the 93108TC-FX3 keep 10GBASE-T copper ports?
Yes. It retains 48 RJ45 10GBASE-T ports that run at 100M, 1G, or 10G, so your existing Category 6/6A server cabling continues to work.
What do I gain by upgrading to the 93108TC-FX3?
You move from 40G to 100G uplinks, gain MACsec encryption, ACI leaf capability, higher switching capacity, and current NX-OS support.
Is the Nexus 93108TC-FX3 ACI capable?
Yes. It can run standalone NX-OS or serve as a leaf in a Cisco ACI fabric, which the legacy 3064-T cannot do.
