<div dir="ltr">Super delayed response; generally agree with the thread -- I've got stuff directly with DataCity, indirectly with Rack & Data, and directly with NetFlash. Looked at NPlus when they were very new, and ran away (don't know how they've changed since).<div>- DataCity and Rack & Data are well connected, good core, and a decent balance of easy-going and operating with rules; I'd talk to them both, and make up your own mind.</div><div>- NetFlash is for a specific mindset - wants bank style handling and *zero* wild-west. See below for more description.</div><div><br></div><div><div><div>As far as heat and such goes, you *can* get a ridiculous amount of power density into a single rack -- say, 3 fully populated blade server cabinets with a couple 15k RPM storage shelves or some GPU shelves or something... lets say you get it into the 7-12 kW dissipated power range. ("Congrats, you the man", etc.). This isn't going to happen by accident. Datacentres vary, but typically, they come with a 120V, 15A gang plug (that's about 1.1 kW max) for a 42U rack -- many don't include any power *at all* as part of your rack price, and your outlets are quoted "a la carte". If you want another 15A outlet, then your monthly costs just went up (say, +$200/mo). So, if you are going to put in 10 kW worth of gear/rack, you are *definitely* going to have a detailed conversation with the Colo Provider about power and cooling.</div><div><br></div><div>One Data Centre that is in town that was not mentioned, but very excellent in certain dimensions, is the NetFlash facility on Victoria St -- it's not big, but if you want your stuff to be in a facility that runs like a swiss watch, they're your guys.</div><div><ol><li>They don't let customers mount or cable anything -- you want stuff in or out, you supply the details, bring the gear over, and *they* mount and cable it.</li><li>It's documented out the wahzo - every plug, every watt, every battery, every screw, every cable is to spec, labelled in a particular way, documented in their DCIM database,</li><li>they monitor and log it beautifully. 4) Access is escorted, certain amount free during business hours/mo, and always paid by the hour afterhours.</li><li>They keep an eye on things (if a light changes on your gear/it changes how it sounds in a not good way, you'll probably get an email).</li><li>Of the local options, it comes closest to meeting Teir III specs ("redundant everything").</li></ol>So, if you want "bank style" colocate and *zero* "Wild West", but you just need somewhere between 1/4 and a few racks, then they are the best local option I know of. (If paperwork, documentation, and process give you hives, for then stay the F*** away). We've got a couple "high" assurance clients who appreciate and have confidence that *nobody strange* is anywhere near their stuff, who appreciate the pros and don't mind the cons of this arrangement, but it certainly isn't for everyone.<br></div><div><br></div><div>As far as NPlus goes -- that building certainly was a dilapidated warehouse/ex-factory the last time I was in, and the folks who were running it at the time claimed it was a "Tier III" data center (cheerfully affirming they were using the Uptime Institute definition: <a href="https://uptimeinstitute.com/tiers">https://uptimeinstitute.com/tiers</a> ), but plainly it was a Tier 1 at the time (The conversation is a bit like this in my memory: "Oh yes, we have redundant power!"; "Q: what's that over there?" "A: That's the generator! It'll be hooked up... /next week/" "Q: /the/ generator? Shouldn't you have two?" "A: Oh, of course, we will!" "Q: So, why does the ceiling look so badly damaged?..."). I haven't been in there in at least 5 years, and they were *just* putting initial overtures out at the time, so ... things may be very different now, and that would be very good for everyone concerned -- if anyone is a current client with current insight, would love to hear it.</div><div><br></div><div>Also, if you have large wads of cash leaving inconvienient scorch marks on your pockets, and/or you need up to 75 MW of power for your new crypto-mining rig, there is a fancy facility right here in Cambridge (just past the Loblaws distribution center on Maple Grove Road): <a href="https://www.google.com/maps/place/ASCENT+TOR1/@43.4270751,-80.3750324,17z/data=!3m1!4b1!4m9!1m3!8m2!1e1!2s110468740494494847556!3m4!1s0x882b8bd3c1e14f4d:0xec6bc1d4ca61b14a!8m2!3d43.4270712!4d-80.3728437?hl=en-CA">https://www.google.com/maps/place/ASCENT+TOR1/@43.4270751,-80.3750324,17z/data=!3m1!4b1!4m9!1m3!8m2!1e1!2s110468740494494847556!3m4!1s0x882b8bd3c1e14f4d:0xec6bc1d4ca61b14a!8m2!3d43.4270712!4d-80.3728437?hl=en-CA</a></div><div><a href="http://www.ascent-corp.com/DataCenters/TorontoDataCenter-TOR1.aspx?gclid=CjwKCAiA-_L9BRBQEiwA-bm5fjcSzFanfmC0p2SOt8XEfZgiTXZ90tShqVtDVc1PmbtKTeGtOHrsbxoCzvUQAvD_BwE">http://www.ascent-corp.com/DataCenters/TorontoDataCenter-TOR1.aspx?gclid=CjwKCAiA-_L9BRBQEiwA-bm5fjcSzFanfmC0p2SOt8XEfZgiTXZ90tShqVtDVc1PmbtKTeGtOHrsbxoCzvUQAvD_BwE</a><br></div><div><br></div><div><br></div><div>-Cedric</div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, 8 Oct 2020 at 09:42, Mikalai Birukou via kwlug-disc <<a href="mailto:kwlug-disc@kwlug.org">kwlug-disc@kwlug.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>I am a total noob in racking servers. I long for explicit clarity
about KiloWatts:</p>
<p> - What KW's your GPU rack is using as 90%-tile?</p>
<p> - How many KW's of heat vendor guarantees to take out, if all
racks produce this amount of heat?</p>
<p> - Does vendor tell you this info?</p>
<p>Implicit human assumption may be that total power available in a
rack, if used, will be dissipated by cooling. Something tells me
that even implicit assumption may be missing from SLA'a. (reminder
to read 'em.)<br>
</p>
<p> - Do you have to space racks out, if they consume all of given
power (e.g. GPU's)?</p>
<p>It be nice to hear both consumed and energy and ability to absorb
it in same nominal units, like KW's, as these are same energy per
time, units of power.</p>
<p>Super-cooled DC is super implicit. What are explicit numbers?</p>
<p>(It happens that I write code that implicitly means the right
thing, but it never convinces the machine. :) )<br>
