I have meet this device seeing Lawrence channel, and it seems interesting to be used only for a few SPF+ connections (in this case at least 3, one for ISP, the other two for two firewalls), instead of using large switchs with 24 or 48, has a very small finger print as well as the MTBF that seems very good (~20 years). The other feature that I loved was the power redundancy.
For now, I just need 1Gbp per port, but in future 10Gbps could be needed per port. On firewalls side, there are SPF+ free ports, to be used in the future, for both LAN and WAN. In terms of WAN usage, right now, I am using VPNs (one site-to-site, and two client-to-side), around 70 devices with internet access. There are backups being done through VPN site-to-site as well as to third party storages, so sometimes we have around 100Mbps for each backup being done in simultaneously for a couple of days per week.
Now, one thing that I am really worried is the heat issue, where I have doubts that a climate room could do any effect because of this device chassis, who doesnt have any fan or even enough holes to cool the hardware inside, seems like the chassis is an extension to cooling inside hardware. The other thing related with hardware, is those electrolytic caps, I have saw too many failing to get that pass =/.
After all of this, I dont know if this switch is the right choice to add between ISP’s and our firewalls.
