we were considering the MS-390 in a design for a customer but after looking at the release notes (even the beta software) we're not really convinced that this switchis ready for action yet.
This is a list from the relase notes and I say it's quite long:
Is there an ETA when this list is implemented / fixed ?
It's also a bit confusing ; we designed a redundant core solution with a warm spare. The datasheet says the MS-390 supports warm spare but the realse notes say VRRP is not supported yet. Are we talking about VRRP with other brands (Warm spare is based on VRRP with Meraki switches) or is this VRRP in general ?
with kind regards,
Hi, I would say if you don’t feel comfortable with the number of known bugs/issues then hold off or propose another device.
Ive read the 390 data sheets and they specify VRRP is supported whilst the Warm Spare release notes don’t mention the MS-390’s. I would go with what’s in the ms-390 datasheets. The warm spare release notes clearly haven’t been updated.
Given the current state of the world and active disruptions that we're all experiencing
I wouldn't place bets on firmware being fixed by Q3/Q4. I am not criticizing Meraki's speed here. I am recognizing that we are not in a usual time or place.
I don't think I would deploy it yet.
But - I'm struggling even for a use case (apart from someone wanting SGT support - which it currently doesn't support ...). Why do you prefer this switch over (for example) an MS355?
The customer needs around 20 SFP/SFP+ ports en 20-40 copper ports in each MER. A stack of 3 MS-390s would be enough otherwise we'd have to make a design with several stacks of MS3XX and MS4XX switches.
With that port density in mind the MS390 with the 8 port 10Gbe module is a nice fit.
I think I would go with a pair of MS425-16's (to get 32 SFP+ ports) and a pair of MS225-24's (to give you 48 copper ports), which gives you two of everything so you have complete redundancy. You can use 10Gbe TwinAx to link the MS225's to the 10Gbe MS425 core. Cheap interconnects.
Plan B, involving just 1 extra switch, would be to go with 5 x MS355-24X. That will give you 20 x SFP+ ports and 120 copper ports. Some customers might prefer to have the single stack. Easy to manage. One "core" switch.
But if it was my money, I'd want the MS425 10Gbe core. I just feels "right".
I've used this exact design (MS425 core and MS225 switch blocks) before with customers and it has worked great. I have had an MS225 server switch block (for those server things still with Gigabit ports) and then MS225 access layer blocks for general connectivity.
Both of these switches have been out for a while and have mature firmware.
Good to hear about the stability. For access switches we went for the 250 because it support redundant power supplies.
We're going back to the drawing board and I'll consider what you're using, thank you.
