[c-nsp] switch for SAN

[Chuck Church]

What are your needs?  10GE?  Layer 3 capable?  There are a lot of small
Cisco switches.  The main difference between the 3650 and 3850 is the
wireless controller thing to my knowledge.  Not really beneficial to a SAN
switch.  Since Cisco tends to not publish buffer sizes for a lot of these
small switches, it's a bit of a guess.  The 2960X are decent for a lot of
purposes, maybe SAN.  That's just a guess though.

Hi all,

 

I know running Catalyst switches for SAN backbone fabric is not the best
idea, due to limited buffers. 

 

However, we have been doing just that with a 3750X and Dell Equallogic
6100/4100s for quite some time, with no issues.

 

We are putting in a NetApp FAS3160 and need to add a switch. I see 3750X is
EOL and Cisco positions the 3850 as its replacement. 3850 is even slightly
less expensive than 3750X.

 

Questions:

-          Should we expect the 3850 to perform as well or better than the
3750X for this application?

-          Is there any other switch we should be looking at which is not
humongously more expensive? Maybe Nexus 3k could work, but it's a lot more
expensive. Maybe 4948E? Seems up there price-wise, too .

 

Thanks,

Adam
