Hi, everyone. Uh My name is Matt Hallberg. I'm a principal product manager here at pure storage as part of the uh platform team. And today I'm going to be talking about uh bigger drives and better T C O as part of a series at pure accelerate. June 14th 2023. So top three things for top of mind. Um You know,
00:25
our goal at pure storage is to uh help our ca our customers build the most efficient data center possible. And with that, um the the top three bullets here, let's talk about rack space, let's talk about power and let's talk about green, right? With rack space, we want to compress your data center footprints with the uh pure storage arrays and high density D F MS.
00:48
On the power side, you know, power cost of premium, we will cover the details and the slides to follow. Uh and on green, you know, you, you basically want to reduce your footprint and pay less green in order to um save costs. So, you know, I'd like to kick things off by saying it's more than just the power bill,
01:08
you know, the cost of data center operations increases with each square foot. I was reading a metric the other day that mentions um the cost per square foot is anywhere from 600 to $1200 for most data centers. And that's, you know, on the lower side can actually get bigger than that. Um So what is, you know, just what the the cost of the data center?
01:29
What is that really built out of? Um I think there are two things, there's a physical cost and then there's that monetary cost that I just caught uh that I just talked about the monetary cost covers cooling power, uh the resources or the man, you know, the manpower needed. Uh and the footprint, how long or how big of a data center you need to rent or build out on
01:51
the physical side. And not a lot of people think about the physical side. Um The bigger the data center, the more racks, the higher number of generators or larger generator that you need, you've got your power distribution units, battery backup units, air conditioning, humidity control, and the cost of personnel.
02:10
Um We actually have on our pure storage website A uh sustainability S L A where we talk about some of these metrics and the ones that I thought were really fantastic were, you know, we are about 85% less energy required than other all flash arrays in the market. And when you look at those hybrid disk arrays we take up 96% less space and equivalently uh 1000%
02:38
more storage density by running uh fewer racks per unit. So, with the space that you have in your data center, you're getting a lot more density. So let's drill down into drives and, and start from there. All right. So let's talk about our next generation direct flash modules, otherwise known as D F MS. They are the largest in the industry.
03:00
Uh We have a 75 terabyte Q L CD F M and a 36 terabyte Q L CD uh D F M. They have additionally on board in the ram which allows us to um have efficiency capa uh capabilities when talking about throwing these into one of our chassis or one of our direct flash shelves and it's faster. So the previous generation was using the P CIA Gen three.
03:28
Now we're running at P CIA Gen four and that gives us a lot more efficiencies in terms of um terabytes per watt performance per watt, et cetera. So when building out a data center, how much power is needed if you have a petabyte as your goal. So, you know, H D DS S sds and D F MS all consume power and they all need cooling in order to operate.
03:54
One thing to note in the table below is that the higher the terabytes per watt, the less power and cooling are needed. So the higher the number uh the better the solution. So let's take a look at uh popular high capacity solutions that are available on the market today. 15 terabyte T L CS sds, 20 terabyte H D DS, 30 terabyte T L CS
04:17
sds, 30 terabyte Q L cs sds. And then the D F MS that I mentioned in the slide before. So we have the 36 terabyte T L C, uh 48 terabyte Q L C and 75 terabyte Q L C um table table here is showing how many drives are needed per petabyte. So if you were to build out a one petabyte system, you'd need 66 drives,
04:39
uh 15 terabytes, 14 of the 75 et cetera, et cetera. And then how much uh how many terabytes per watt are you getting out of the drive? Uh lastly for that petabyte, how many watts from the drives alone are needed per petabyte? So you'll see here on the bottom where I highlighted the 406 315 and 210. Those are the best of the bunch,
05:05
meaning you're gonna need less drives uh and less power in order to hit a petabyte. But let's talk about that in detail. So these are the, again the peer store direct flash modules. If you're running mission critical data load, uh data workloads, the 36 terabyte D F MS are the solution for you. Those are available in the X S and XL s, uh they use 61% less watts per petabyte than the
05:30
15 terabyte T L cs sds and 44% less watts per petabyte than the 30 terabyte T L cs sds. The 48 terabyte D F MS for the business critical workloads. Uh You see the numbers here, 37% less than the 20 terabyte S sds and surprisingly, um 61% less than the 30 terabyte Q L cs sds.
05:53
What's that? You notice that the Q L cs sds actually consume more watts than petabyte than uh 20 terabyte H T DS. Yeah. Very interesting when you look at it from that perspective. And lastly, the big drive we're super proud of is the 75 terabyte D F M. So 58% less watts than those 20 terabyte H D DS
06:14
and 74% less watts than the 30 terabyte Q L cs sds out in the market today. So now that we've talked about the power efficiencies and the, and the watts per petabyte on the drive. Let's talk about rack space and reducing that rack space and how much rack space is needed to get to a petabyte data center. So the drive immediate capacity is gonna directly affect the rack space to achieve your
06:43
storage capacity targets. So you know, the denser the drive, the fewer the drive slots, expansion shelves and those Pesky control units are needed. So one thing to keep in mind with this table is I'm only looking at expansion shelves. I'm not counting all the other stuff that you need in order to drive those expansion shelves.
07:02
So control strollers, um other types of, you know, other, other types of, of components that uh other manufacturers use to basically talk to those flash shelves. So if you're using H D DS, because they're 3.5 inch, typically, it's about 12 hard drives per two U. And if you're using an S S D and AD F M in the popular 2.5 inch form factor,
07:25
it's about 24 S sds per two U. So per media type, this table source shows out how many terabytes you can get per rack unit and how many rap units it's gonna take per petabyte. So if you were to build um a one petabyte, uh a one petabyte data center and you are using these D F MS, you know, when you look at the 75 terabyte,
07:47
it take you a little bit over one rack unit to get to that petabyte. That's pretty intense when you think about where things are with like hard drives, right? It's gonna take you almost nine rack units per petabyte. And again, that's just a single petabyte and that's just the expansion shelves. So that alone is,
08:06
you know, kind of interesting. It's, it's an interesting concept to think about just how many petabytes or how many rack units are needed from a drive point of view. But let's take that up a step and look at what's needed at the system level. So this is a comparison of the flash arrays, uh flash array C against the hybrid media arrays. Um I've got two examples in here and then the bottom chart shows are flash array X and our
08:32
flash array XL 1 70 compared to other solutions in the market. So you look at uh the effective capacity of 8.9 petabytes. And I was able to go get data for um hybrid meteor rate A and B at the same effective capacity. And you'll know right off the bat that six U total rack units to hit 8.9 effective uh petabytes compared to 48
09:00
86. Yes, 48 86 those hard drives and 15 terabyte and below uh S sds really consume a lot of space along with all the controller units and everything else. Not only that, when you look at the amount of power that's required that C 90 is gonna use 1651 watts. And when we talk about cooling it requires or
09:26
it generates 5800 and 83 BTU S per hour. Comparatively speaking, using the hybrid media arrays, you could tell that your power bill is going to be way more expensive and the cooling is gonna be way more expensive like more than uh eight X on hybrid A meteor array A and then almost six X on hybrid media array B.
09:53
And then when you throw in the 75 terabyte drives that it mentions in that same six U, you're able to drive up to 13.6 petabytes effective capacity. So again, that concept of reducing your data center or getting the most out of your data center is really important here, especially when you think about um how much it costs per square foot. So the bottom table here is showing the T L C
10:19
based or you know, better known as mission critical based solutions or storage arrays. And I grabbed the flash array X 90 and the XL 1 70 is a couple of examples and grabbed two of the more popular all flash array solutions on the market today. So what we're gonna look at is the total number of rack units, the total number of watts and the BTU per hour required.
10:44
Um I try to find the best matching effective capacity across all three or sorry, all four configurations. So for the X 90 for 3.35 petabytes, we use a six U for the competitive solution A it's eight U. You look at the power here, it's basically double the amount of power required for that uh competitor and almost double the amount of BTU S per hour when you look at the flash A X 1 70.
11:14
And these are all using the 36 terabyte drives that I mentioned before, we're able to get to 5.6 petabytes of effective capacity in eight U versus 14 U. And again, when you look at the total watts, you know, much more power efficient, way better on the BTU S per hour. So for your mission critical data center, um or your mission critical racks,
11:38
you're gonna be saving a lot of money, a lot of cooling and a lot of space. So with that, I I want to talk about green, right? Green is a term that you hear quite a bit in the market. And for pure, you know, we've always been about talking to talk and walking the walk, right? A lot of competitors, a lot of people in the
11:56
market say they're green. But when you go look at the kind of products that they offer, where is the green at, you know, some important uh data points here, data centers in the US are responsible for about 2% of the total global gro uh greenhouse gas emissions and global data centers consume about 3% of the world's electricity. So data centers have quite the footprints in our world.
12:20
Pure storage solutions use about 80% less power than those hybrid arrays and 40% less power than all flash arrays. The estimated cost for data centers is around $1 per watt per month. So you know, the more you can reduce the amount of watts the less money you're gonna be paying per month, the more green that you are. And lastly when you also talk about like the
12:45
impact of, you know, landfills and everything else. Our D F MS are seven times more reliable than hard drives. Five times more reliable than S sds, which would reduce the need to replace your storage media and the impact that causes the landfills. Lastly, I just want to close out and say, you know, pure storage, less power, more storage and somehow being green actually saves
13:09
you green with that. I'd like to thank you for your time. Have a great day.
