DART 5.6.49.3 with 2xdatamover- how configure nics and devices for fast response in CIFS

Jump to solution

hello i have a dilema how to configure my nics for CIFS service, having 2 datamovers en primary-standby mode,

my doubt is how to configure my 4 phisical nics of the primary datamover, in order  to have best performance,

1. use them individually

2. use them with fsn1(cge0 and cge1) and fsn2(cge2 andd cge3)

3. use them with link agregation option

wich of these option could be the fastest mode to have best performances for only 1 CIFS server.

any suggest

if i choose 3, how to configure the switches, is there any guide from powerlink to do this.?

it is going very dificult finding guides about this.

if i choose 1 how to use all of them individually just for 1 CIFS server?

whatever you do for primary datamover has to configured identically for standby (celerra and switch side)

This is my config:

1) cge0,cge1,cge2  - connect to network switch 1 - LACP is enabled on the switch for these 3 connections. On Celerra side i configure these 3 into an LACP trunk

2) cge3 - connects to network switch 2 - nothing is done on Celerra

next i combine LACP trunk (that was created in step 1) with cge3 and form FSN device where trunk is listed as my primary interface.

Hopefully that makes sense.

I would use option 2 (both fsn and trunking) if I had two switches and cared that my CIFS server is still working if one switch fails

If you don't have two switches or all your clients are connected through one switch it's a moot point

you won't find much on Powerlink how to configure your switch - you really need to look at your switch vendors docs for EtherChannel or LACP - it's pretty straightforward

i did FSN that consists of LACP (primary connection): cge0,cge1,cge2 and regular cge3.  My position is that i would like to give my users as much connectivity as possible with the caution that if the network switch that has LACP connection dies, they will be running in "degraded" mode on cge3 only.

in your choice,

how the nics work just 1 primary and the others 3 in standby mode, is not clear to me

other thing making redundancy from the switch side,

how could you connect them with 2 ethernet switches,

is it necesary work with 2 switches yes or no and why?

any sugestion

could be this work?

standby datamover  ---------------------      primary datamover

cge0 ----- cge1 ----- cge2 ----- cge3       cge0 ------ cge1 ------ cge2 ------ cge3

  |              |             |               |            |               |              |             |

sw2p1    sw1p1     sw2p3     sw1p3     sw1p1      sw2p2     sw1p3       s2wp3

  

how could you configure FSN and LACP with two switches is it posible yes or not.

thank you

questions:

when configuring LACP on every port that is going to be used

the first three ports cge0,cge1,cge2 have traffic at the same time?

converting this connection in a 3Gb interface is it correct?

other thing following your configuration

you mean that at the switch2 side, there is going to be only 2 conections coming from primary and standby datamovers?

thank you

yes, they will have traffic at the same time but think of it as a 3 x 1G lane autobahn. No one car can drive at 3G but 3 cars can drive at 1G concurrently .

yep, 6 connections on switch 1 and 2 connections on switch 2.

thnks you

now see about this new config i am thinking

from primary datamover all 4 port configured in LACP mode connected to switch-1 and

from standby datamover all 4 port connected to switch-2, all of this, in order of getting the most performance connectivity,

is it valid?

what could be the risks?

my questions are in this new config:

1. if one port from a  primary datamover or one port used for LACP of switch-1 gets failed, does the standby DM takes personality of primary  DM?

2. what could happend if entire switch-1 failed, does the standby datamover takes personality of primary DM too.

thanks

network failure is NOT a trigger for automatic failover
