Fiber cable question

airborne spoon

I am upgrading my house to 10 gigabit connections (because i feel like it) on my computers and learning on the fly.

I have bought everything off eBay and amazon but now realize i may have a problem... or not i dono stuff is still in the mail


CISCO WS-C2960S-48LPS-L CATALYST 48 PORT PoE+ SWITCH

Intel EXPX9501AFXSR 10GbE XF SR Server Adapter x2

10GBase-SR SFP+ Transceiver, 10G 850nm MMF x2

 

So the NIC and SPF are SR which i didn't notice till this morning will those work with the switch?

Also i didn't know there was a difference in cables (SR and LR) so i grabbed 1x 3ft multi mode cable for the switch to the NAS but i grabbed a 50ft single mode cable for the switch to my main computer. Do i need to get a multi mode cable to replace the 50ft one or will a single mode cable work in a multi mode connection?

Id personally run it all single mode.

Thats xr not sfp+, you probably don't want it, id getting something like a x520 or connect x3 instead

Id probalby go mikrotik or other newer switches. This is gonna be loud and power hungry.

but the NIC is 10G why is XR bad vs SPF+

 

the switch will be in the garage and I have free electricity so that doesn't matter.

 

Also i already bought this stuff (its in the mail currently) and while i can just but them back on eBay to sell, i don't see the need unless something literally will not work. which is what i was asking originally.

There are lots of 10g standards.

 

XR is a different connector than SFP+, so your transcievers won't work. Its also a old eol standard, so finding parts will be harder, and software support is probably gone for the nic too.

Ok that is what i was wondering thanks.

can you recommend a card that'll work with freeNAS or TureNAS? Also i'm looking for cheap hence the eBay searching

Look at those nics I suggested earlier? Connect x3, x520. For other cards, id google to see wht peopls experience with them on freebsd is.

The switch doesn't have 10gbps ports.  It has 4 SFP ports, capable of maximum 1 gbps.

So it's kinda pointless ... I mean you can still use it for the 48 x 1 gbps ports but why waste a couple hundred watts for a gigabit switch. You could just get a basic non-management switch if you want that.

I'd suggest getting a microtik 5 port 10g switch with 4 sfp+ ports and 1gbps rj45 port, at around 150$ or less.

 

The cards are bad choice like someone already said. You'd need a switch with XR ports to use those cards. Luckily sfp+ cards are relatively cheap, 35$ and up...

The solarflare cards use common/popular intel  and broadcom "chipsets" so they should be supported.

 

you can just google model names and truenas / freenas and find out

SolarFlare: Some users recommend the SFN 5162F. @jgreco notes he just got four SolarFlare SFN6122F on eBay for $28/each, with SR optics (3/2019). This is awesome for ESXi as the SolarFlare burn half the watts of the Intel X520's. We've had several confirmations that the SFN6122F works fine with FreeNAS/TrueNAS, and is currently the cheapest option on eBay (9/2021).

I just got a Solarflare dual 10Gbit SFP+ card from eBay. Price was 70€ for a new card. The card is working just fine with FreeNAS-11.2-U7. I use it in passthrough mode in ESXI 6.7 U3. Therefore I had to install the legacy drivers from the Solarflare site. No drivers need in FreeNAS. Speed is awesome!
