Hi there,

is there any recommendation for the right switch forwarding performance (Mpps) depending iSCSI?

We need two 24-port switches with 12 x 10GBit SFP+ and 4 uplinks with 10 GBit SFP+ each.
The switches will be used for Virtual SAN and Hyper-V iSCSI only.

The switches we have in mind have a forwarding performance of 480Mpps. Is that enough for a hyper-converged Virtual SAN environment?

Thanks in advance!

I assume it depends only on the amount of data you will be operating. The calculation is quite simple. If the overall writes/reads throughput will be within 480MBps limit you will be fine with it since starwind will be able to push this amount if data through synchronization channel.

Thank you for the information so far.

My problem is that I don´t know if a iSCSI switch with 480 Mpps will bottleneck Virtual SAN.
Is 480 Mpps a good package throughput compared to a usual switch?

Well, Mpps is packets per second. With Jumbo Frames enabled your single packet size will be something near 9000 bytes. So I think you will have way much less than 480 million per module.

If 9k packets (9000 BYTES), what sould be something like 150k packets/s on a 10gig-link.
64 byte packets would max out at 20Mpps for a single 10gig link.
These are single direction numbers, so double the numbers for full dupex.

Lohelle, DarkLight - thank you very much for your contribution.

Anything else I can help here with?
