Hi!
I am working on a system, and I would like to ask you for some help.
I have basic knowledge about FC configuration of this devices… And my plan cost more than a “lets give a try” so I really need your opinion.
I have 9 points with Fiber connection (orange fb cable).
On this 9 points I have right now 3cameras/point in a switch and a single 10/100mb media converter… (FC → ETH)
In the building I have a 10/100 mb media converter, and than it goes into the 100 mb eth switch…
I will configure a lenovo rack server for the video processing, and it will has two 10 gb fc ports for ethernet, so the question, will it works fine?
Outside at the 9 points 3 camera / 1 RB260GS, connected with an FC, inside the another side of the FC into the the CRS326-24S and the CRS326-24S with two fc into the server.
And if I keep te main switch, what do you recommend to the 9 points? I only need 1 SFP/SFP+ on the 9 places and multiple 2-5 ETH , so I need extra switch to this places..
260GS is enough for 5 cameras, in my experience 5 cameras cannot get more than 1Gbps traffic! Also CRS328-4C-20S-4S+RM has 24Port SFP to connect endpoints and 4 Combo {Ethernet / SFP+ (10Gbps)} to connect server with SFP+ or 10Gbps Ethernet Cards!
Alright, so I can go with this hw, or I can go with your switch. Its cool, I think I will buy the switch what I selected, because I need 5 x10GB ports.
Between the server and the switch I can use DAC cables, right?
As I wrote I never worked with fc “really deep”, so the last question, how can I figure out which SFP module should I use in it? Is anywhere a compatibility matrix? And It should be the same module on both of the sides? So the 260GS sfp modul should be the same in the inside fc switch?
For maximum compatibility go for fibre connection. Use SFP modules compatible with corresponding device (i.e. in 260GS use Mikrotik’s SFP, in Lenovo use their SFP, no need to have identical SFPs on both ends), only concern is that both SFPs must support same fibre technology (wavelength, single/multi mode, same range, same sync speed e.g. 1.25 Gbps).
Additional benefit of using fibre is that it doesn’t create grounding loop (which might affect performance of copper connections).
But If I use 10 gb lenovo dac cable between the mikrotik switch and the lenovo server, it will works fine? DAC cable has his own connector if I am right the spf port is integrated with the fc cable… So how will I know my selected cable is good with my Server FC card and with the mikrotik switch?
Mikrotik devices are fairly picky about SFP modules … they only work with a few (some devices don’t even work with all Mikrotik SFPs, so one has to consult SFP compatibility matrix).
DAC cables are another kind of beasts … there are passive (i.e. only connect SFP pins) and there are active (i.e. contain chips) … some Mikrotik devices don’t work with passive DACs … and with active DACs you’re in the situation of picky devices.
