I was just noticing how much 10GbE cards have dropped in price

I would not run ethernet at all and just go fiber due to the run length implementation. Granted you can put 10 GBE transceivers in all these SFP+ cages. Like I said before almost nobody needs this much speed so probably a waste for me.

 

Adapters

 

amazon.com - Amazon.com: Lot Of Two HP 10GB Single Port Mellanox Connectx-2 PCI-E 10GBe Ethernet Network Interface Card 671798-001/666172-001 (Bulk Package): Computers & Accessories

 

$44 for two

 

Transceivers

$16/ea

 

Fiber

Varies by length

 

Most affordable switches maybe have two SFP+ ports but can point to point to your hearts content as that is a pretty low berrier. Saw a mikrotik with 8 for $3000 lol.

 

Wish whoever tries this luck.

Was saying not to virtualize if you can run in native BSD in a jail.

 

Still don't think you will get enough speed to be worth it with mechanical hard drive anyway. Maybe if everything SSD or M.2. I have an 18TB raidz2 with 6 3TB red drives write speed is about 70 MB/s sustained and read is bottlenecked a bit to about 100 MB/s. Figure at best maybe get like 150MB/s read.

 

This makes sense as main reason for NAS is redundancy not speed.

 

Adding a 10 GB card does not magically give you better performance unless the network is a major bottleneck.

At work I'm running into an issue where all my servers are reporting 10 Gbps, but some appliance in the network is throttling the connection to 1 Gbps. Really, that's typically fast enough; but we started noticing it when backing up large (500+ GB) databases. Even then, the Gigabit network is probably fast enough - just not as fast as SSD on the SAN.

 

I'd like to have 10 Gbps LAN in a home lab for iSCSI - I'm just not sure it's necessary.
