[c-nsp] Experience with Lenovo switching, anyone?

[Greg Antic]

We chose Mellanox/Nvidia due to price, port density, port speeds, hardware performance. Yes the onyx software is basic but cisco asr provides dci features not included or go cumulus. This will connect our hyperconverged environment running nutanix soon.

Hi ,

Mellanox (or should we say Nvidia now?) is overkill for 1G ports, but is
interesting and very competitive at high speeds.
Here in Milan they are using them at MIX for 100G ports and seem to be
happy.
Their base software is lacking some features, for example in data center
interconnect, but you can run cumulus on them to extend the feature set by
purchasing a license directly with the box.
They will then offer support for the hardware and cumulus directly.

Hi,

We've moved to Arista for the "1RU, lots of 10/25GE ports, MLAG"
places in our network, and we are very happy.  Stuff works like a breeze
- and
if it doesn't (we found a bug with IPv6 and OSPFv3, of course) ATAC is
really
pleasant to work with.

Turned out to be too expensive for us. 1 G/s more than enough as edge
connectivity for servers, not that much ???hyperconvergence???
going on, yet. That???s why it does not pay (yet) to have higher
bandwidth at
the ToR.

Indeed, for 1G, Arista is fairly pricey.

So I???m looking for 2-3k for a ToR switch - upper limit. We are
replacing
refurbished Cisco gear that came at 600 per 48 1G ports with 2 10G
uplinks.

It???s really hard to find current manageable gear for our size ...

Have a look at Juniper EX3400.  24 or 48x 1G, 4x 10G, and reasonably
priced
(they can do routing, but the routing license costs extra).

... that's where we went when Cisco annoyed us too much in the 1RU
L2 switching sector...  with nice ideas like a "yearly recurring license
fee"
(catalyst 9300 series), etc.

(Sorry for not answering your original question - no idea if their gear
is any
good, but after a bit of experience with "other" switching gear -
Extreme,
Supermicro, Intel/ONS - this is what we've landed at, Juniper for 1G and
some
10G, Arista for 10G+MLAG+Routing)
