Nexus 5548P vs Nexus 5548UP

[HUBERT RESCH]

I have a question regarding Nexus 5548UP which is supported from NXOS 5.0.3 on.

I assume thats the absolute indentical hardware as the Nexus5548P which was available a little bit

earlier and had also the HW ready for support Unified Ports on all Ports (but was just enabled on expansion-module).

Is it possible by SW upgrade to 5.0.3 to make a 5548UP from a 5548P ?

Thx

It's actually different.

5548P can do Unified Port (Eth,FC,FCoE) on the expansion module only

5548UP can do unified on all base ports and expansion module.

So 32 UP ports is the main addition to 5548UP vs 5548P and latency wise, the 5548 UP is a bit better, 1.8usec with 5548UP vs 2 usec for 5548P.

Finally, Back-to-front airflow will be on 5548UP and 5596UP but not with 5548P.

Thx Lucien,

then there is absolutely no reason to buy the 5548P, because 5548UP has same price, and no reason to buy another expansion-module than the UP(has the same price as well compared to the other expansion Module ?

So I assume 5548P and the pure Eth-uplink Modul, and the mixed FC and Eth-uplink Modul will have very limited lifetime ?!

One additional Question: I read that in case a 5596 has L3-Modul built in , it no longer supports the maximum numbers of FEXes  it supports only 8 then.

Is this a limitation which will remain, or is there a chance new NX-OS Versions will break thhis limit

I dont know about pricing (and the periodical promotions), this is something you can address with your cisco sales / account team.

When there is an L3 module and you have Layer 3 to your access level (to your servers) yes we scale up to 8 FEX for best performance.

If your FEX are straight trough to each 5k and you have vPC to your server, then you can do 2 times 8: 16 FEXs (8 on each 5k).
