RE: Eaton 9130 UPS feedback
I've had issues and experience with many types of UPSes, including HP (probably OEM'd from someone else), APC, EATON/Powerware, and Liebert/Emerson. I keep coming back to APC. Solid units, and are always slightly 'ahead' in technology. Sure, I've seen each model have failures and even faults (big boom style), but APC provides a solid product and supports their customers the best if you ask me. That being said, a very close second choice would be EATON/Powerware. - Erik -Original Message- From: Seth Mattinen [mailto:se...@rollernet.us] Sent: Tuesday, November 13, 2012 1:59 PM To: nanog@nanog.org Subject: Eaton 9130 UPS feedback Does anyone use Eaton 9130 series UPS for anything? I'm curious how they've worked out for you. I bought a 700VA model to give it a whirl versus the traditional APC since the Eaton is an online type with static bypass and also does some high efficiency thing where it normally stays on bypass, but the first thing it did on the bench was have the inverter/rectifier or bypass section catch on fire and destroy itself. ~Seth
not excactly on-topic Server Cabinet question
I apologize for this being off-topic in the NANOG list, but I'm hoping some of you have experience with the particulars of what I'm looking for... I am looking for a server cabinet which has an electric latching mechanism on it. I want to use my existing security system and proximity card reader, but have a cabinet door that would open when the card reader is read. Does anyone sell anything like this? I've looked into Rittal, APC, Hoffman, Wrightline (now Eaton), Knurr (via Liebert/Emerson), Middle Atlantic, and Panduit. So far, nothing. Any suggestions? Feel free to reply off-list. - Erik
RE: Yup; the Internet is screwed up.
My big concern with pitiful low speed upstream speed is the whole 'cloud' movement. Every one will have all of their 'data' in the 'cloud' sooner than we all think, and that involves uploading it from their PC to the 'cloud'. For instance, I use a 'cloud' drive to backup bunches of data (150+GB of data). However, doing the initial backup really is no fun, even though I have a 10Mbps connection at home, the upload is more like 1.5Mbps. 150GB over 1.5Mbps is no fun, and most 'non-technical' folks would have given up a long time ago trying to backup that data... The 'cloud' is going to create a strong 'want' (some may choose to call it a 'need') for higher speed brodband, and symmetrical speeds. - Erik -Original Message- From: Seth Mattinen [mailto:se...@rollernet.us] Sent: Thursday, June 23, 2011 1:52 PM To: nanog@nanog.org Subject: Re: Yup; the Internet is screwed up.

I continue to be amazed at the quality of Netflix video coming across the wire. Our local cable company just recently upped their old 7M/512K normal tier to 10M/1M, and is now offering much higher speed tiers as well, which isn't going to be discouraging to anyone wanting to do this sort of thing. What still dismays me is the pitiful low upstream speeds that are still common. Not because most people want to run servers or host content at home (they don't), but because they want to share content with friends and the user experience can be greatly enhanced with symmetric speeds. Sharing those HD videos or 1,000 pictures during party weekend is less painful if it takes 10 minutes to upload rather than 10 hours. Also, things like GoToMyPC and back to my Mac are end user experience things that are best served by not using horribly low upstream speeds. I can understand that a decade ago most people were still sharing content offline, but dare I say now sharing online is becoming more common than offline. I guess the most telling bit of all this was when I found myself needing an ethernet switch behind the TV, AND WAS ABLE TO FILL ALL THE PORTS, for Internet-capable TV set Internet-capable Blu-Ray player Networkable TiVo AppleTV Video Game Console Networked AV Receiver UPS and an uplink of course. 8 ports. Geez. That keeps striking me as such a paradigm shift. I was talking to one of my friends about when we wired his house a while back. When he moved in we wired the crap out of it - we put Ethernet ports in the kitchen, behind the sofa, everywhere. The one place we didn't put anything though was behind the entertainment center. We put it lots of coax and wiring for surround sound, but at the time it never occurred to us to put Ethernet there. Of course, now there has to be without question. ~Seth
RE: Yup; the Internet is screwed up.
I agree, the whole use of the terms 'need' and 'want' in this conversation are ridiculous. It's the Internet. The entire thing isn't a 'need'. It's not like life support or something that will cause loss of life if it isn't there. The only thing to even discuss here is 'want'. Yes, consumers 'want' super-fast Internet, faster than any of us can comprehend right now. 1Tbps to the house, for everyone, for cheap! - Erik -Original Message- From: Michael K.

Right now, I'm running an rsync job to back up my laptop's hard drive to my office. I hope it finishes before I leave today for Denver. I understand the sentiment, but the comparison is flawed in my opinion. The speeds back then were barely any faster than you could type, I know all too well the horrors of 1200/75 baud connectivity. Luckily nowadays now it's about getting your dvd torrent downloaded in 2 minutes, vs. 20 minutes, or 2 hours. Or your whole disk backed up before your flight leaves. You're now able to back it up online to begin with. The thing here is that I talk about *necessity*. Once connectivity has reached a certain speed threshold having increased speed generally starts leaning towards *would be nice* instead of *must*. And so far the examples people gave are almost all more in the realm of luxury problems than problems that hinder your life in fundamental ways. If you have a 100 mbps broadband connection and your toddlers are slowing down your video conference call with your boss by watching the newest Dexter (hah!). Then your *need* can be easily satisfied by telling your toddlers to cut the crap for a while. Sure it'd be nice if your toddlers could watch Dexter kill another victim whilst you were having a smooth video conference talk with your boss, but it's not necessary. Greetings, Jeroen To paraphrase Randy Bush - I hope all my competitors work on their version of what their customers need versus what they want. Why on earth would you not want to give them what they want? Why does need have anything to do with it, particularly when need is impossible to quantify? Mike
RE: Open Source / Low Cost NMS for Server Hardware / Application Monitoring
We've been using Ipswitch WhatsUp Gold for many years. Their recent improvements to the product have been mainly system monitoring stuff. The product has grown in capabilities hugely since version 4 when we started with them (they are on version 12 now), and with that improvement in capabilities, the price has gone up a bit. It's still a whole lot less than most other options, however. There isn't too much in the way of agents, but we've integrated a ton of proprietary systems with WhatsUp Gold via it's SQL database back-end. They also have fully scriptable monitoring as a standard feature now. Anyways, thought I'd put in my two cents... - Erik -Original Message- From: Matthew Huff [mailto:mh...@ox.com] Sent: Wednesday, July 22, 2009 1:08 PM To: 'nanog@nanog.org' Subject: Open Source / Low Cost NMS for Server Hardware / Application Monitoring I apologize for not starting a new thread before, I didn't realize that the nanog mailing list created a thread-index rather than using the subject. Even though NANOG is primarily for network operators, I know that a number of members work in NOCs where there is also monitoring of servers/applications. I would appreciate it if anyone has suggestions about monitoring systems that would be applicable to our environment.

RE: MGE UPS Systems
We asked our local APC rep that exact question last week. He told us that the MGE line of UPSes fill a whole that APC doesn't have in their own lineup, and they will continue being sold as the product for folks absolutely require a typical double-conversion online UPS. As opposed to the 'hybrid' model of the Symmetra... It didn't sound to me like they were planning on getting rid of the MGE line at this point. - Erik -Original Message- From: Seth Mattinen [mailto:se...@rollernet.us] Sent: Monday, July 13, 2009 2:43 PM To: nanog@nanog.org Subject: MGE UPS Systems I'm curious if anyone might know what the future of the MGE line of UPS systems are.

DNS issues?
We just lost DNS totally for a while and just got it back...XO communications also lost almost all Internet routes at the same time... Anyone else noticing weirdness? Erik Amundson

Cause (losing all routes) - effect (can't reach stuff other side of the routes, including DNS servers)? Sounds like an XO routing issue, not a DNS issue.
RE: DNS issues?
I was having issues reaching any of the roots, and any of the TLDs for .com and .net. I tested them directly, and had no luck. I was merely looking to see if anything was broken elsewhere in the world to see if it was just my network so I could diagnose things a bit better. XO's problem eventually got fixed (relatively), and I was suddenly able to get answers from the roots/TLDs again over Verizon Business/UUNET/MCI/WORLDCOM/whatever, and Qwest after about 45 minutes. I have found no explanation for the loss of connectivity as of yet. I found it strange that I had issues reaching the name serves even after shutting off XO, so that's why I asked... Some of NANOG folks have been helpful and kind, some not, but I read NANOG a lot, and I'm not surprised. :) ThanksI guess. Erik Amundson
