Since, my doctor recommend that I put more fiber in my diet- I decided to comply.
So… in a few hours, I will be running a few OS2 runs across my house, with 10G LR SFP+ modules.
Both runs will be from my rack to the office. One run will be dedicated for the incoming WAN connection (Coupled with the existing fiber that… I don’t want to re terminate). The other, will be replacing the 10G copper run already in place, to save 10 or 20w of energy.
This, was sparked due to a 10GBase-T module overheating, and becoming very intermittent earlier this week causing a bunch of issues. After replacing the module, links came back up and started working normally… but… yea, I need to replace the 10G copper links.
With only twinax and fiber 10G links plugged into my 8-port aggregation switch, it is only pulling around 5 watts, which is outstanding, given a single 10GBase-T module uses more then that.
Edit,
Also, I ordered the wrong modules. BUT… the hard part of running the fiber is done!
Ahhh gotcha! You should document and post the process. I’d love to see it!
I have quite a bit of it already documented!
Might be worth a read.
Although, will note, the 40G project is quite a bit more interesting then these 10G runs. I did also run 100G a year or so back, but, never posted anything on it, due to a ton of firmware issues on the 100GBe nics.
Interesting blog!
Clicked on your NAS article (one of the first linked ones) and spotted an error… you write that Synology NAS boxes don’t use standard RAID, but they do. They have official docs up on how to hook them up to a standard Linux system for disaster recovery (it’s just Btrfs or ext4 on mdadm RAID).
Probably not super relevant for you or most readers, but just thought I’d point it out :)
Interesting, was not aware of that.
I am going to assume you found the post regarding the 500$ closet NAS I built a few years ago.
One of the driving reasons behind the inclusion of that, was actually taking a jab at drobo units, which after failure… which, while recoverable, takes a decent amount more effort then just plugging the drives in elsewhere.
Yeah Synology is pretty good with that kind of stuff (we use one at work). They’ve really just got a Linux system with custom management tools on top. Of course for DIY purposes, self-building is still cheaper and more flexible though.
I might have to give them another evaluation.
My current issue… is just the amount of energy needed to run this bulk storage array… I need to identify a solution that allows me to have a large number of drives, good performance, AND low energy usage.
