Experience with Lenovo switching, anyone?
Hi all,

we are looking for alternatives to the two large vendors
that are cost efficient for a small hosting company.

Does anyone have practical experience with Lenovo
ENOS and is willing to share?

With a limited budget we prefer to cut features rather
than stability ;-)

Yet multi-chassis (at least dual-chassis) LACP or similar
or some modern „fabric“ architecture are necessary.
I don’t want to go back to only STP …

Kind regards,
Patrick

What features do you need? "Switching" or "full L3 routing"? And
if routing, how large the table?

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.

The only negative aspect so far: for "mostly the same hardware",
Arista pricepoint is slightly above Juniper (7050SX* vs. EX4600/QFX5120
etc.) - but especially the time saved with niceties like "MLAG that just
works" has been worth the extra CAPEX already.

Check out Fortinet, they have switches and are very good

Switching. A new layer 2 „fabric“ for our data centre. I’m planning to
go back to a router-on-a-stick design and separate routing and
switching …

If routing is available and stable, it would not hurt, of course.
OSPF for v4 and v6, strictly IGP, definitely no uplink. Table size?
Well, how many routes can you put into a v4 /20 …? ;-) Similar
for v6, so „couple of dozen“ to „couple of hundred“. Less than
1000 routes definitely.

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.

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 ...

Thanks,
Patrick

Indeed, for 1G, Arista is fairly pricey.

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)

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.

Thanks to everyone who responded.

We will look into Lenovo CNOS gear.

The switches are easily available through one of our established
channels and very attractively priced.

I’ll report how that goes …
