Re: Colocation Server Lifts
Very good questions with not so clear cut answers.

Definitely ask before hand so you understand what you are getting into.

My guess is it facility dependent. > 4. What would be the typical device weight you would lift? The answer really depends on how much you want to lift manually. The guys I use are pretty comfortable racking 80 lb servers over and over and over again. But if you don’t feel comfortable then a server lift at any weight is a good idea. Save you back! > 5. What would be the max device weight you would lift? Not sure on that one. You should probably consult the manufacturer. I can tell you we typically use server lifts when things get over 100 lbs. I think the heaviest box we have installed using a server lift was over 200 lbs. My guess is that it would support a lot more weight. > > Thanks, > > Jason
Re: Data Center operations mail list?
HI Guys: I must have missed this but where can I sign up for this new mailing list? Thank you.

I can definitely switch it elsewhere, so please let me know what you have in mind. I can let the mailman server do deliveries as well, so that's a second option.

This is a profoundly horrible idea, not through any fault of yours, but because Amazon's cloud operation is a massive, non-stop fountain of spam and Amazon personnel flatly refuse to lift a finger to do anything about it. As a result of this incompetence/negligence, some folks out there have taken defensive measures which may include firewalling, blocking, discarding, rejecting, etc. Thus this is not someplace that you want to try to send mail from if you really care about having it delivered. I recommend moving it elsewhere. And I'm perfectly willing to assist with that (either selecting another location or facilitating the move or both). ---rsk .

Re: recommended outdoor enclosures
I came across this once. Seems interesting but we have never used it ourselves. 400 Watts is not much so I believe this unit may even be overkill. http://www.ellipticalmedia.com/raserhd.html On 6/17/2013 3:36 PM, Chuck Anderson wrote: I'm in need of my first free-standing, pad-mounted outdoor enclosure, 19" rack rails, 12-18 rack units, with about 400W of heat load inside, for use in the Massachusetts climate. What do people recommend as far as contruction, cooling/heating options, NEMA ratings, security options, etc. for this use? I was hoping to keep the inside temperature between 50 and 85 degrees Fahrenheit, although my worst-case components are rated for 41 to 104 F (4 - 40 C). If a full mechanical A/C system can be avoided, even better. A thermo-electric cooler would be nice. Thanks.
Re: Anyone know of a good InfiniBand vendor in the US?
Hi Landon: We deliver Infiniband based servers and switches. We have been working with Infiniband for many years already. What are you looking for? Alex www.pssclabs.com On 2/19/2013 2:11 PM, Landon Stewart wrote: Hello NANOG, We are thinking of utilizing some InfiniBand stuff for some specific application in our data centres. We are new to InfiniBand however so we want to get some equipment and see if it does what we need. Does anyone know of a good vendor in the US? East or West coast, doesn't matter. If anyone has any good advice or information about InfiniBand that would be nice to hear too as we are totally new to it at present.
