My office has two managed Netgear Gigabit switches GSM7248R with an Ethernet cable connect each other as uplink. Now the office is expanding and we need at two extra switches. I have thought of the following choices:
A) Get four brand new stackable managed switches (GSM7352S-200) with additional 10GMbps modules for stacking (~$3800 x 4 solution). Single management with enough throughput between switches. The cost will be about ~CAD $3800 x 4. it is way too expansive.
B) another alternative: Get two other similar switches as other two GSM7248-200 and interconnect them with an Ethernet cable. It cost about $1600 only. However, central management is not a big issue here. but i think i need to set up LAG on all switches to avoid bottleneck traffic among switch.
I have the following questions:
1) Is there any better option other than A and B?
2) If I go for option B, how do I implement it for LAG among 4 switches. I have been googling lots of info. and it usually says for LAG between two switches. What is the topology looks like? Is it something like the link below
3) Does stackable or non-stackable managed switches provide any bandwidth monitoring/usage?
4) for option B, How do I know how many link (2 - 8) required for the LAG pipe? If I apply 8 link, does it mean I got a 8GB link between?
