8320 with 10Gb uplink towards 2930M stack, 2930F

Hi,

we are trying to design small campus network around 2x8320 as redundant core with few access switches connected to it over MM FO, 10Gbps. 

 However, looks like 40Gb ports on 8320 can be brought down to 10Gb with adapter as it is possible on 5710. Any other ideas around this?

Small slide attached.

Hi!

 

I think your sentence:

 


@damima wrote: However, looks like 40Gb ports on 8320 can be brought down to 10Gb with adapter as it is possible on 5710.

should be correctly rephrased into: "However, looks like 40Gb ports on 8320 can't be brought down to 10Gb with adapter as it is possible on 5710." because no break out solution is available to split one 40Gbps port (QSFP+) into four 10Gbps ports (SFP+) on Aruba 8320.

Yep, you are right. English is not my native language and sometimes I make mistakes like this :-(

If you are planning a VSX (two Aruba 8320 interconnected by using VSX) and you have mostly 10Gbps downlinks to your access switches (stacks or standalone) you would probably use the JL479A (Aruba 8320 with 48 SFP+ ports plus 6 QSFP+ ports)...in that case SFP+ ports can be used to connect (through what are called Multi-Chassis LAGs or VSX LAGs) to your Access Switches that should use LACP as link aggregation control protocol (so each Access Switch should be connected to the VSX by means of two - or more - 10Gbps physical links aggregated into a LAG Link Aggregation Group, also called Port Trunking on HP/HPE/Aruba switches running the ArubaOS-Switch NOS). QSFP+ ports can be used with DAC Cables to form the VSX Inter Switch Link (ISL) plus a SFP+ port used for VSX Keepalive link.

Then I would need 4 of them, since  servers are 10Base-T (not SFP+). So ideally, it is 48x10Base-T + 8xSFP+ 

Looks like Aruba doesn't have solutions comparable to Cisco 9300 or some Huawei or H3C switches. 

Haven't paying much of attention to Cisco until now. Their 9300 has modular slot for uplinks so you can chose how to upgrade. Better approach then Aruba, IMO.

What's about Aruba CX 6400 Switch series? it's modular...

Event with 2xmgmt modules, still SPOF. Event 8200zl and 5400zl we have been selling for 15+ years and only one actually had to be replaced, we parted away from this just because this one customer. He made huge issue around it so we went towards IRF stuff. HPE then acquired Aruba and we are somewhere where we are deciding whether keep going with Aruba anymore since it is not clear what HPE and Aruba wants. They don't have switches Cisco, Huawei, Extreme, H3C has so we are scratching our heads now. 

 

So being SPOF and also being bit pricey. I don't believe we can push it.

Reached. Only shaking heads. That's reason why I came here looking for ideas. They don't have any.

Are you stuck on using the 8320? I think you would need two stacks with the 10G SFP+ model and 10Base-T model(Basically two of each). I may be wrong but am not sure if either switch by itself is going to accomplish your requirements. You might be able to to work this with a 5412 zl2 with two 8 port SFP+ modules and six 8 port Smart Rate modules, depending on total needed 10base-T you may need dual 5412's or might be able to get away with two 5406 instead. 54125412
