Re: [swinog] QSFP to SFP+ breakout cables ?
Hi Markus I'm looking for reasonably priced QSFP (40GE) to SFP+ (10GE) twinax breakout cables (3m long or so). I can order via ebay for ~$150 but I was wondering whether there's a local distributor who has a stock for them and doesn't sell them at 500CHF or more... Any recommendation? Sadly, nothing in our stock currently. Also, what kind of adapter would I need to break out a QSFP to 4 SFP+ sockets (where I could then attach fiber SFP+)? Haven't seem something like that, but perhaps I'm searching wrong? You’re search is correct. Technically it will be a challenge to build such a part as you need to provided power and management-signaling for 4 x SFP+ (in total 6 Watt power consumption combined to one single QSFP+ port). Regular QSFP+ to SFP+ Breakout DACs are „just“ and extension of the high speed lanes via the Twinax-cable. Can you explain your application in more detail? An alternative for such a „port-splitter“ (QSFP+ port to 4 x SFP+ port) could be that you use QSFP+ SR4 (4 x 850nm) or QSFP+ Parallel LR4 (4 x 1310nm - https://www.flexoptix.net/en/qsfp-plus-parallel-lr4-transceiver-40-gigabit- sm-1310nm-10km-7db-ddm-dom.html) straight ahead. Combine it with a MPO breakout cable (Multimode or Singlemode) and you can connect 4 x SFP+ as counterpart interface directly. The majority of QSFP+ based gear supports 4 x 10G operations of the QSFP+ port today.

Re: [swinog] green power: dew point calc..
Hi Julien, I would like to do free air cooling for some small datacenter. Idea is to use cold air from outside to cool the servers room in order to limit AC power when possible. I like that idea getting rid / reducing the amount of chillers. I have sensors inside servers room and outdoor to collect temperature and humidity. I calculate both dew point and try to estimate thermal bridge value. Perfect! Has anyone already worked on this can give me some clues? Harald (harald.ros...@erecon.de) from erecon did already something similar in the past to heat up it's office (during winter ;-) and cool down its servers. He has a nice and successful approach doing this. I met him on a datacenter event. cCheers Thomas ___ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog

Re: [swinog] ASR 9k zum ausprobieren ?
- Funktionieren 10GE Menara XFPs ? Meinst du tunable oder fixed DWDM ? Braucht ihr FEC ? Mann kann die Menara XFPs auf verschiedenen Wellenlängen programmieren, dazu müssen sie allerdings aus dem Router gerausgenommen werden und in eine Box gesteckt werden. Sie sind also nicht fixed - aber auch nicht live-tunable. Jup, mit unserer flexBox machen wir genau das und macht dein DWDM Netz super flexibel. In wie weit die FEC machen, weiß ich leider nicht (bin nicht so in der Optik drin - und mein Kollege ist gerade auf Dienstreise). FEC wird interessant wenn du DWDM Strecken 80km mit einem XFP ausleuchten willst. Weiterhin müssen beide Seiten müssen FEC machen (die ASR kann das mit einer zusätzlichen Lizenz!) - Funktionieren 100MBit/s SFPs in den GE Ports ?

Re: [swinog] Barracuda ES.2 is affected too! SeagateBarracuda 7200.11defective, replace immediately
If you got the ES.2 from NetApp I would assume that either a different firmware was used (NetApp certifies the firmware for the disks they are selling) or that they've already fixed it on maintenance. Though I certainly wouldn't bet my data on it and check with NetApp directly to get a reliable answer from them. If you - no, we just do have the ES.2 disks and do make use of the openfiler-project. just got the empty shelf from them and plugged the disks yourself then you may be in big trouble already. In the MSFN thread there are many people who lost their ES.2 the same way the 7200.11 dies (the unbrick recovery procedure is exactly same for both). - lucky us, we still have some WD drives around the place and put them into operation. Currently the RAID is syncing. Btw, do you know if you can ship the ES.2 to Seagate through the regular RMA procedure to get them fixed (I assume a firmware-upgrade should help)? Is there anything I should reference to. I mean the drives are still working at the moment... Thanks for your advices.
