Re: Network Vendor suggestions/reviews, Arista Networks, Dell Force10, Juniper, Extreme Networks etc...

[Michel de Nostredame <d.nostra () gmail com>]

DELL Force10 switches (not DELL Power Connect) run so far so good in
our environment. the combination of S4810 and Z9000 make good sense on
both operation and capex point of view.

There were three headaches for us in the beginning of adaption.
Force10 calculates frame size with CRC32, say if your IP MTU is 9000
on VMware then the trunk port on Force10 should be 9022. Although it
clearly documented in manual but still troublesome for people who
lives in Cisco world for all his past life and want to use non-default
MTU (1500) on Force10 switch.

Another headache was Force10 needs to manually config MTU (if not use
default MTU) on every interface even if the interface is member of
port-channel and you do already config MTU on PO interface

The last one was the way how it creates VLANs. Not like Cisco, Force10
cannot creates say hundreds of VLANs in one single line, but need to
create VLAN interface one by one, even if they are purely layer-2
VLAN, not RVI.

However, those 3 things can be managed by script or by using the free
deployment tool, AFM, from DELL. Beside those 3, so far the switches
run rock solid.

One very good benefit is Force10 does not (almost) have virtual port
limitation like Cisco does. (Force10 has completely no limit when use
RSTP. and 250 x ports when use PVST. You can google "Cisco virtual
port limit".) This freedom is extremely important when operate large
flat layer-2 network for VM.
