Network Engineers/Network Administrator I need your opinion on this

[huryhoy]

---

Good day istoryans!

FYI: I'm not a Cisco certified, I'm also not network guru. I'm just basing everything on my experience.

Scenario:

I got 3 physical network as of the moment.

1. Admin Network compose of the following: (Back bone: Cat 6 cascading)
* Database Server
* Application Server
* POS Server
* Etc..

2. Guest WIFI (Back Bone: Cat6 cascading)

3. IP CCTV (Back Bone: Fiber)

What can you suggest? Stick to 3 physical network or change it to virtual network and use fiber as back bone to 3 network?

I was thinking that, these existing physical network cost them huge amount of expenses. And fiber optic back bone for CCTV network is just a waste of investment since it is just used for CCTV.


My question is this:

1. If I will convert the Guest WIFI and IP CCTV network into Virtual is it going to be okay interms of data transfer and all?
2. Do I need a fiber optic core switch?
3. What will I do so that I won't experience bottle neck on the data transfer?
4. Is there a chance of improving the data transfer for the Admin Network?

My target:
1. Fiber Optic will be used as Back Bone for the existing 3 Physical Network.


Note: I already have HP managed switch which is everything is in flat network design only.


Your inputs are highly appreciated.

Thank you and have a great day!

am not a network guru shit either, nor Cisco certified... but... some terms are a bit weird for me (I might be wrong)

Back bone: Cat 6 cascading

-too misleading?, Cat 6 can be either to go speeds from 10Mb to 10Gb

I got 3 physical network as of the moment.

-are these separate/individual networks you are saying?, like one is 192.168.1.1 and the other is 192.168.2.1?

(Back Bone: Fiber)

-is this indeed a fiber network and/or with a fiber switch?

What can you suggest? Stick to 3 physical network or change it to virtual network and use fiber as back bone to 3 network?

I'm trying my best to understand what you really need..., so you are asking if you need them to be as-is or have them 'combined' as one network?


ug aron makasabot kog tarong ug uban pang tao diri, ma-o ni ako pangutana sab:
-the 'servers' that are running on the network, what are their speeds? 10Mb, 100Mb, 1Gb?
-the wifi AP's (AP lang ato itawag as of the moment), are these regular B/G/N wifi? or higher?
-the CCTV, are these IP/LAN based units? or using coaxial cable?


sa imo number 1 question:
-is guest wifi running "IEEE 802.11ac"?, is CCTV's individual cams capture in HD quality?, how many 'people' are accessing this wifi?, how many CCTV cameras are there?

number 2 question:
-do you need a fiber optic switch..., ambot, if memory serves me right..., having a fiber optic based device will mostly be incompatible with your current setup..., so palit kag fiber optic pci/pci-e cards for your servers?, too costly I guess

number 3 question:
-unsa imo bottleneck?, you did not even mention it ^_^

number 4 question:
-hire me ^_^, joke...., hahahhaa

Di pod ko network guru Boss, pero ka-relate lang ko gamay.

Ako suggestion...

Ideally, mas maayo nga 2 networks imo ipa-run just to separate the core operations and external operations.

-- 1) mas maayo nga imong i-separate ang "#1" Boss. Kay mao na ang core sa inyong operations.
Ayaw saguli og lain like wifi guest or cctv. Kay basin mao ra na'y maka-kaon og maayo sa inyong resources labi na jud ig-magpadagan og back-ups on all CCTV cams.

-- 3) Need ba jud og internet and/or LAN connection inyong CCTV?
Mag tan-aw mo sa CCTV kamong tanan through your PC's?
Gusto mo mag-tan-aw sa inyong CCTV on your mobile gadgets online via DDNS etc ?

If yes, then i suggest you create a separate network for this.
If no, aw pasagdi na ang current setup oi.

-- 2) For guest wifi, if mag "yes" ka sa --3) , adto ni i-connect.
If mag "no" ka on --3 , then no choice but to connect it to --1).
Tarunga lang jud ang firewall ani.

By the way, on the 4 questions, IF "solid" imong internet connection, i bet wala ka'y problema sa data transfer.



...suggestion ra ni hap.

Goodluck.



ps: Unsa diay nature sa inyo company or business Boss?

@dab_s_bad:

Thank you sa imong reply! hehe..

Mao ni akong mga tubag sir.

Cat 6 can be either to go speeds from 10Mb to 10Gb

Cat6 backbone is just cascading sir. Ang Admin network is just compose of those servers. and then ang mga client to other building ang ilang backbone from server is naka Cat6 lang using unmanaged gigabit switch. So from Server Switch to other building switch to other building switch. I hope sakto akong na tubag nimu. hehe..

are these separate/individual networks you are saying?, like one is 192.168.1.1 and the other is 192.168.2.1?

3 physical network jud sir. separate. they have their own switches. For example sa Building 1: I got 3 switches ana nga location. 1 for Admin, 1 for Guest WIFI and 1 for CCTV. which is ang CCTV lang ang naka Fiber optic cable ang backbone. So ang mga switches sa CCTV Network naay fiber port or sometimes using SFP port or using Fiber Optic Media Converter.

is this indeed a fiber network and/or with a fiber switch?

Kini wa ko kasabot sa Fiber network and/or fiber switch. hehe.. Ingon ani ang situation dri ron, from my office nag latag ni sila ug FIber Optic Cable going to other building location nga kinahanglan ug IP CCTV Cameras. Ang problema lang kay some of the locations is just using Fiber Optic Media converter. Some building sad direct jud ang fiber to switch kay naay fiber port or SFP Port.

ug aron makasabot kog tarong ug uban pang tao diri, ma-o ni ako pangutana sab:
-the 'servers' that are running on the network, what are their speeds? 10Mb, 100Mb, 1Gb?
-the wifi AP's (AP lang ato itawag as of the moment), are these regular B/G/N wifi? or higher?
-the CCTV, are these IP/LAN based units? or using coaxial cable?

-Servers: 1GB
-AP's: BGN
-CCTV: IP/LAN based units

-is guest wifi running "IEEE 802.11ac"?, is CCTV's individual cams capture in HD quality?, how many 'people' are accessing this wifi?, how many CCTV cameras are there?

-for the guest WIFI I guess not. CCTV cameras some are HD quality some are not. People access this WIFI: As many guest as we can. hehe.. (depends on the occupancy). CCTV Cameras: I think more than 50. Naa pa additional Cameras coming. hehe

-do you need a fiber optic switch..., ambot, if memory serves me right..., having a fiber optic based device will mostly be incompatible with your current setup..., so palit kag fiber optic pci/pci-e cards for your servers?, too costly I guess

Regarding this Sir, I was just asking if I need a fiber optic core switch. Para tanang other managed switch nga naka deploy sa lain-laing lugar nga naka fiber adto nalang sak2 sa core switch. so all of my backbone will be fiber na.

For example:
Building 1 Managed Switch naa syay SFP port/Fiber Optic port for Fiber Optic. And that port connected na cya diretso sa akong Fiber Optic Core Switch.
Building 2 Managed Switch same scenario
and so on..

-unsa imo bottleneck?, you did not even mention it ^_^

Ayy.. sorry. hehe.. I was just wondering man gud sir if akong i.VLAN ang other network naku. So in 1 switch naa koy isa ka port nga naka Trunk going to Server Room arun lahos tanang VLAN. Of course naa koy management VLAN which mao na cya akong Admin Network. Let's just say VLAN 10 for Guest WIFI and VLAN 20 for CCTV. mao nang nag ask ko kung dli ba cya ma bottleneck ang Trunk Port naku nga 1GB ra man cya.

I really hope nga na tubag naku imong mga pangutana. hehe.. bisag ako naglibog na sad. hehehe..

[dab_s_bad]

so the whole LAN segment jumps from one building to another? wow!!!
also..., vlan(ning) will not help out, as you really need to isolate imo so called 'bottleneck'

kani nalang..., ako Makita bottleneck kai kaning bldgA to bldgB, unsa nag-interconnect nila?

[Devian]

okay man na nga design nga gi separate network nimo ang 3 ---- security purposes.

to increase bandwidth sa imo admin network you can do port aggregation/etherchannel kung kaya sa imo switch. puede sab cya mahimo redundancy sa imo uplink in case maputol usa ka cable.

Actually wala pa man cya nag botthleneck karun sir kay physically separated pa man cya. What I'm after man gud is ang fiber optic. Gi sayangan ko nga gi gamit ang fiber optic just for CCTV. And wala gi gamit for Admin network which is naa diha tanan among gamit for the operation.

Mao na nag ask ko if akong i.VLAN ang mga network, dli ba kaha cya mag bottleneck sa Trunk Port.

BldgA to BldgB is just using CAT6 sir. Mao ra jud ni akong target as of the moment nga magamit naku ang fiber sa Admin network instead of CCTV.

I was also thinking maybe pwede ra naku iVLAN ang Admin and CCTV and physically separated na ang WIFI for security purposes. Peru mao lagi na, dli ba sad kaha mag bottleneck ang Trunk Port nga Operation Network and CCTV mo passthrough niya.

Thank you sa reply sir. Actually okay man jud cya as of now nga naka separate ang 3 ka network. Ang ako lang jud gi sayangan or bothered kaayo ko nganung wala gi gamit ang fiber network for Admin/Operations which is critical kaayo kaysa CCTV. ang CCTV Camera Network man gud karun ang naka fiber. And then ang Admin/Operations Network naka Cat6 lang, Cascading pa jud ang switches from 1 Bldg to another. Unya kay ang Existing Fiber Network dri kay Each Building goes to Server room man jud cya. Mao nang naka huna2 ko nga what if akong gamiton ang fiber sa Admin Network together maybe sa CCTV. Peru same question lang gihapon, dli ba kaha mag bottleneck akong Trunk Port? huhu..

Study pa lang ni sir kung unsa maayo buhaton para lang ma achieve naku akong gusto. Sa pagka karun, pwede ra baya ni naku pasagdan. peru mao lagi na, naay panahon jud nga mo hinay akong Operations nga application. Maybe because of too much resources coming in/out sa One switch port going to servers.

pila man diay speed sa imo fiber? ug kaya sa fiber ang traffic then go.... sakto man ka na imo usahon passing thru fiber then i vlan to separate virtually. ma minimize sab ang cost. Ang importante maka estimate sa needed bandwidth ug kaya ba sa fiber.

kaya ba ang etherchannel sa imo switch? kay mao ra ni maka-tabang nimo to increase bandwidth over existing link.
