Have questions about the 10Gbbit network?
The T2 card is available in Ethernet and SFP+ formats. When talking about SFP, I mean the physical interface, not the electrical standards. SFP works with Ethernet, InfiniBand and Fibre Channel networks (though they can't be mixed). Plugging an Ethernet SFP+ card into another Ethernet SFP+ card lets them communicate via Ethernet over a more advanced cable. I mainly work with HPE products, but my overall experience has been solid. Their newer 2930M series switches are excellent for managed networks.
I can't provide an answer to that. I'm not confident in my response. You mentioned uncertainty, so it's best to avoid making assumptions. The Broadcom BCM57810S you referenced is SFP+, which doesn't fit your requirements.
Are you sure you need 10GbE? I've set up Docker clusters on Raspberry Pi devices and a server with a 100 Mbps local connection. What kind of tasks will you be handling? (Even though each Raspberry runs at 100 Mbps and there are four of them, your server uses Gigabit Ethernet.) I’m new to ESXi and understand that connecting multiple machines with 10GbE switches could be costly. If backups take too long, think about more frequent backups or alternative tools. (I don’t know the operating system you’re using.)
I move large files between my main tower and server regularly (about every half hour, such as during backups). Each file is typically 5-10 gbytes. My main tower runs Windows 10 Pro and Arch Linux (dual boot, but mostly Windows), while the server uses ESXi.
He plans to handle backups extensively, making it much more resource-intensive than typical Raspberry Pi setups. Still, 100GB backups can fit within a 1Gbps connection and will require about 160 minutes for a complete backup. It’s not the most efficient, but it’s manageable. @Nolanrulesroblox what ports are needed and what’s your budget? If you only need a few 10Gbps ports and are fine with SFPs, the QSW-308S is a solid option. It costs around 160 dollars for three SFP+ ports and includes eight 1Gbps ports. You can also purchase it with a combo port for flexibility between SFP and RJ45 connections. You could also buy three 10Gbps DACs for roughly 20 dollars on Amazon, allowing you to connect three computers via 10Gbps links for about 220 dollars plus the cost of network cards. It’s a straightforward configuration, though the switch lacks advanced settings and I haven’t found it very reliable in practice.
You have roughly $500 and are considering trying an SFP option.
When selecting SFPs, verify the compatibility of the model with your existing equipment. Physical fit isn't enough—functionality depends on proper integration. For instance, an SFP designed for HP devices won't work with a Cisco switch, and vice versa. DAC cables consist of permanently attached SFPs on both ends, using copper connectors for short distances (typically a few meters) and supporting 10Gbps speeds. Some SFPs can be converted into standard RJ45 ports.
The server also manages backups alongside the Raspberry's, though I perform backups roughly twice a day, which shortens the backup duration.
That's what I'm considering doing (I mentioned I'm not at ease with standard SFP cables)
