We are working on implementing 2 MS355-48X2 servers in our Datacenter soon and slipped my mind about the QSFP+ ports on these.   These switches will have their own uplink to our FortiGate firewalls and servers will have NIC1 going to SW1 and NIC2 going to SW2 on the 2 MS355's. I won't be stacking these to avoid downtime during firmware upgrades but should I use the QSFP+ so that connectivity between the 2 switches will be able to take advantage of the 40GB speeds?     ...

Hello,   I am looking to upgrade our Datacenter backbone to a 10GB network and am evaluating between MS355-48X2 vs MS425-32 switches. Essentially this is a Layer 2 switch with critical devices behind it. I am currently using all ethernet for my servers so going with the MS425-32 would require me to purchase individual SFPs that support this.   My plan with the MS355-48X2 would be to put my 1GB ethernet devices on the 1GB ports and 10GB ethernet devices on those ports so it's nice to have both on one switch. I don't need the POE features, it's just part of the switch but the advantage is I don't need a SFP to convert each port to ethernet and pricing.   My plan with the MS425-32 would just be to move everything to it with the SFP to convert to ethernet.   My biggest comparison between these 2 switches I can see may come down to performance and that's what I'm looking for some help from the community on. Any big performance differences between these 2 switches? I recall reading something about MS425 having shared buffering and 1ms latency(?). Is this true and what does the MS355-48X3 have in these areas?  ... View more

I current have 2 MS225-48 switches in a stacked configuration in our datacenter running a Hyper-V Failover Cluster 20-node setup. We're looking to upgrade these for 10GB switches and the MS425 series caught my eye as being the only Meraki Switches I could achieve the amount of 10GB ports I needed. We have basic L2 needs but looking to upgrade from a 1GB to 10GB setup.   I plan to not have them stacked so I don't endure the brief downtime of the entire stack going down during firmware upgrades.   I was doing reading and while I really enjoy Meraki switches and haven't really had issues saw others mention to not use them for datacenter use cases (aside from cost) because of speed issues versus other brands Such as the 800Gbps switching capacity.   Anyone have speed issues or other issues implementing MS425 Switches in a datacenter environment?  ...

We have a datacenter setup that's core backbone is setup with 2 MS225-48 Meraki switches in a stack with 10GB stack cables. Each switch has its own 1GB uplink cable to the firewall but of course one of them is discarding packets in the stack setup. All of our servers have redundant ethernet uplinks going to each stack switch.   It's been great for us so far, haven't had any issues but I run into troubles when it comes to Meraki's software upgrades with stack setups because it reboots both stack switches at the same time. This causes a brief network outage which generally isn't a big deal but we have a rather large Failover Cluster environment running on it and some VMs will go into "Saved" states after everything recovers post-switch upgrade.    My question is, should I take apart my stack switch setup since I have redundant uplinks on my servers to both switches and will I lose out on any performance? I'm fine with managing these switches manually since in Meraki it's already easy. My main goal is to make maintenance periods much more manageable and no impact to my Cluster environment. ...
