00:00:00.480 --> 00:00:07.600
this is a video I've been meaning to make for quite some time because I've

00:00:04.440 --> 00:00:10.240
been meaning to practice what I preach

00:00:07.600 --> 00:00:15.879
for quite some time and that is to always have a backup of your data

00:00:13.000 --> 00:00:19.359
preferably one that is offsite which is easier to say than to do I mean if

00:00:18.039 --> 00:00:23.720
you've just got a few smartphone pictures you can use a cloud account or

00:00:21.519 --> 00:00:28.359
even burn a couple discs once a quarter to act as your Disaster Recovery storage

00:00:26.199 --> 00:00:33.440
solution but if you're talking about dozens of terabytes worth of video and

00:00:31.720 --> 00:00:37.840
we're talking video that could be needed at any given moment for smooth business

00:00:35.800 --> 00:00:46.959
operation you better have something a little beefier so meet Cam Loop

00:00:49.480 --> 00:00:57.840
server whether you run a small business or A1 billion Enterprise Rackspace has

00:00:56.000 --> 00:01:00.440
your dedicated storage environments covered check out the link in the video

00:00:59.559 --> 00:01:08.000
description to learn more so this project starts

00:01:04.199 --> 00:01:10.600
actually with undoing most of what I had

00:01:08.000 --> 00:01:16.280
planned from before I had intended to use the same Norco RPC 4224 case from

00:01:13.920 --> 00:01:23.799
the high-speed SSD server which can handle 24 drives on sleds with a SATA or

00:01:20.040 --> 00:01:26.759
SAS compatible back plane thing but iar

00:01:23.799 --> 00:01:33.720
USA reached out and showed me this the ex 4M 36- exp and my plan plans changed

00:01:31.040 --> 00:01:38.040
somewhat at that time so at the front of this case you'll find a 24 hot swappable

00:01:36.200 --> 00:01:46.520
hard drive caddies that work with 3 and 1/2 or 2 and 1/2 in drives some sick ass

00:01:41.960 --> 00:01:48.960
beefy 120 mm cooling fans and this SAS

00:01:46.520 --> 00:01:54.280
back plane that connects on the inside with the usual Molex power connectors

00:01:50.840 --> 00:01:56.600
and sff 887 SAS connectors with the

00:01:54.280 --> 00:02:03.119
difference and this is cool being that it doesn't actually require six SAS

00:02:00.280 --> 00:02:08.800
connectors for all those 24 drives you can even use just one if you want and

00:02:06.759 --> 00:02:14.920
the back plane handles routing that traffic to all the connected drives now

00:02:11.920 --> 00:02:17.280
obviously with just that one connector

00:02:14.920 --> 00:02:22.360
you won't necessarily be able to run all of those bays at the same speed as if

00:02:20.160 --> 00:02:26.519
they were individually plugged in but for an off-site backup server will where

00:02:24.680 --> 00:02:33.879
we'll never do more than gigabit speed to the whole box this is way more than

00:02:30.599 --> 00:02:37.160
enough but hold on a second Linus since

00:02:33.879 --> 00:02:38.720
when is more than enough enough I

00:02:37.160 --> 00:02:43.040
thought this was Linus Tech tips why aren't you sticking with the Norco case

00:02:40.519 --> 00:02:47.319
that drives every single connected Drive individually at full speed great

00:02:45.280 --> 00:02:55.959
question and we can answer it by going around the back of the ex 4M 36 ESP yes

00:02:52.519 --> 00:02:58.080
friends that is another 12 drives back

00:02:55.959 --> 00:03:04.400
there giving us a total of 36 drives of expansion that thanks to

00:03:01.680 --> 00:03:11.760
the built-in SAS expander boards can be driven off of just two SF 887 ports

00:03:08.640 --> 00:03:14.040
absolutely perfect for an unraid

00:03:11.760 --> 00:03:18.040
deployment which doesn't mean that there aren't any compromises that were making

00:03:16.080 --> 00:03:24.239
with a configuration like this I mean I get effectively only a 2u height

00:03:21.040 --> 00:03:26.720
enclosure inside my 4u case to install

00:03:24.239 --> 00:03:31.360
all the rest of my internal components so let's meet those internal components

00:03:28.480 --> 00:03:36.120
shall we first is our motherboard a z9p u8 server board from ASUS with a couple

00:03:34.080 --> 00:03:42.360
of features that make it ideal for this build number one is the ipmi intelligent

00:03:39.480 --> 00:03:46.720
platform management interface module that we've added to it when you can't

00:03:44.560 --> 00:03:51.400
have physical access to a server because it's a 6-hour drive away one of these is

00:03:49.879 --> 00:03:56.360
critical because it allows you to perform low-level functions through a

00:03:53.640 --> 00:04:01.079
dedicated special Ethernet port on the back that normally couldn't be done

00:03:59.319 --> 00:04:05.760
through conventional Network control Solutions like team viewer or remote

00:04:03.439 --> 00:04:11.400
desktop connection things like altering bio settings or hard resetting the

00:04:07.959 --> 00:04:12.879
machine number two is that it's

00:04:11.400 --> 00:04:18.799
compatible with some Hardware that we had lying around like these 46 gig ECC

00:04:16.000 --> 00:04:23.919
DDR3 Kingston RAM modules that I've actually had kicking about the office

00:04:21.040 --> 00:04:29.880
since uh course Kingston sponsorship deal for that whole room water cooling

00:04:25.880 --> 00:04:33.360
project over a year ago and this Zeon e

00:04:29.880 --> 00:04:35.479
5 2620 V26 core that I pulled out of our

00:04:33.360 --> 00:04:39.960
storinator server when I needed a higher clocked CPU to overcome some SMB

00:04:38.120 --> 00:04:45.560
bottlenecking so I could have tried to Source a better CPU in this case because

00:04:42.199 --> 00:04:49.120
while 64 GB does give me the option to

00:04:45.560 --> 00:04:52.000
run some VMS I suspect this machine

00:04:49.120 --> 00:04:57.840
won't do much more than store files so I kept things pretty light for cooling I

00:04:55.600 --> 00:05:02.800
obviously couldn't stick with my go-to server heat sink the noct to any

00:05:00.320 --> 00:05:10.199
d9l because of the limited height that I had to work with so I opted for an

00:05:05.680 --> 00:05:12.199
nhl12 with the top 120mm fan removed and

00:05:10.199 --> 00:05:16.880
since this is only an 80 wat TDP chip with ample case air flow it's not really

00:05:14.680 --> 00:05:23.000
a concern to just have that bottom fan on there next is our HBA card and I've

00:05:20.360 --> 00:05:27.840
actually been using raid cards uh many of which I had lying around already so

00:05:24.720 --> 00:05:30.160
it wasn't a matter of extra cost for HBA

00:05:27.840 --> 00:05:36.479
or host bus adapter Duty but what I found out relatively recently

00:05:32.319 --> 00:05:38.000
is that even ones with good jbod mode so

00:05:36.479 --> 00:05:42.840
that's just kind of like an HBA mode where you just connect drives and they show up to Windows like they're just a

00:05:40.160 --> 00:05:46.759
drive no raid they don't behave completely transparently which can

00:05:44.919 --> 00:05:52.319
interfere with operating systems like freas and unraid getting proper smart

00:05:50.000 --> 00:06:00.280
data readings from the drives so I'm actually using an LSI 9300 8i HBA so it

00:05:56.680 --> 00:06:02.319
has zero raid capabilities whatsoever

00:06:00.280 --> 00:06:06.880
then I've got a couple of mini SAS HD connectors that I can use adapter cables

00:06:04.199 --> 00:06:12.919
to plug into my back planes leading us finally to hard drives yes my friends

00:06:10.280 --> 00:06:17.759
the 8 tbte Seagate Enterprise capacity drives are making yet another appearance

00:06:15.599 --> 00:06:22.680
here in all of their Glory these are only SATA drives but for our workload it

00:06:20.280 --> 00:06:27.280
really won't make any difference and SAS controllers are compatible with SATA

00:06:25.240 --> 00:06:31.880
drives just not the other way around which you can learn more about here so

00:06:29.680 --> 00:06:36.199
these are true Enterprise grade drives not the shingled archival ones and

00:06:33.720 --> 00:06:40.919
they're capable of their full read and right speed so somewhere in the

00:06:37.280 --> 00:06:42.479
neighborhood of 230 to 240 megabytes per

00:06:40.919 --> 00:06:46.319
second According to some right speed testing that we did when you're just

00:06:44.240 --> 00:06:50.319
hitting one drive at a time freaking awesome they also offer excellent

00:06:48.520 --> 00:06:55.000
resistance to vibrations from nearby machines a must for data center

00:06:52.960 --> 00:07:00.160
deployment and a massive 2 million hour meantime between failure rating with all

00:06:58.199 --> 00:07:04.039
of them installed then so we actually had only 23 left after the ones we've

00:07:01.840 --> 00:07:09.080
deployed already all that's left to find out is how much performance we can get

00:07:07.080 --> 00:07:14.400
with so many drives hooked up to a single connector and actually that is

00:07:12.319 --> 00:07:18.960
looking pretty darn good thanks to the 12 gbit per second SAS controller we're

00:07:16.680 --> 00:07:23.720
using and the rated internal bandwidth of about 2.4 GB per second for that SAS

00:07:21.720 --> 00:07:30.560
back plane at the front we could write to our array of 22 discs at about 2 gab

00:07:28.039 --> 00:07:36.560
per second more more than we'll need even if we upgraded to 10 GB internet

00:07:33.720 --> 00:07:41.000
since this server will be off site freaking

00:07:38.319 --> 00:07:45.840
Ballin speaking of Ballin were you thinking you might want a solution

00:07:42.879 --> 00:07:50.800
that's a little bit less handson than this well there's Rackspace it's the top

00:07:48.919 --> 00:07:55.240
tier managed cloud computing company and they Pride themselves on best-in-class

00:07:53.120 --> 00:08:00.120
service across all platforms they've got over

00:07:56.520 --> 00:08:02.599
300,000 customers and 120 countries with

00:08:00.120 --> 00:08:07.159
10 worldwide data centers whether you run a small business or a billion dooll

00:08:04.720 --> 00:08:12.039
Enterprise you probably have needs for capacity so that is to say magnetic hard

00:08:09.599 --> 00:08:16.440
drives or flash-based so that is to say high performance storage and I can

00:08:14.400 --> 00:08:20.960
guarantee you they have some kind of a solution to meet your performance

00:08:18.280 --> 00:08:25.199
security network capacity and compliance needs I mean they can handle anything

00:08:22.800 --> 00:08:30.000
Daz so that's directly attached storage so it's great for like entry level uh

00:08:27.400 --> 00:08:34.399
redundant arrays they've got so that's high availability and

00:08:31.919 --> 00:08:38.440
reliability fully redundant storage that's actually outside of the machine

00:08:36.880 --> 00:08:42.880
like elsewhere in the data center but with super highspeed links there's Nas

00:08:41.039 --> 00:08:49.720
with support for very demanding workloads for example virtualization and

00:08:46.120 --> 00:08:52.560
scalability up to 20 pedabytes of

00:08:49.720 --> 00:08:57.279
capacity seriously go do the napkin math how much is that freaking incredible and

00:08:55.360 --> 00:09:02.440
they've actually got public cloud and private cloud-based options available as

00:09:00.200 --> 00:09:07.200
well so you can set up your own server with a scalable private cloud in your

00:09:04.680 --> 00:09:14.000
data center or theirs and it's supported by Rackspace and VMware they refer to

00:09:10.040 --> 00:09:15.680
their 247 365 support as fanatical and

00:09:14.000 --> 00:09:20.320
they offer industry-leading service level agreements so the call to action

00:09:18.160 --> 00:09:25.079
then is pretty simple Rackspace has your dedicated environments covered so check

00:09:22.120 --> 00:09:25.079
