In a system like this, you *always* put hotspares. It makes immediate notification more of a "hey it's time to do an RMA" notification rather than a "time to run and put a drive in" warning.
Also, I have my Areca card set up to send an e-mail address to my e-mail -> txt converter @ att. (Your phone number @providersmsgateway.net usually).
I don't agree with this. I agree that having coldspares is good (having a drive around so you can make an immediate replacement) but if the machine at your home then you will always be able to replace the drive in <24 hours. I do agree it is important to have a spare so you can replace the disk in a timely fashion.
Does the ARECA software support SMTP authentication? I ask because virtually every SMTP gateway provider has this requirement - gone are the days when they simply checked your IP address...
Apologies for the dumbness, but what's an SM board? (I don't get to play with servers and RAID controllers much)
Acronym for SuperMicro. I used to use regular brands myself until I started working in a data center and realized how superior they are to other brands.

Supermicro is above Tyan. Best of luck to you if you ever have to RMA something with Tyan. Supermicro is the brand to get when it comes to server boards.So how would you compare them to a brand like Tyan?

Your lack of updates is disturbing.
what are you using for backup?
Any benchmarks yet?
Are you going for hardware raid?
Small, isn't it
Very nice setup! Can we ask what you do for a living? I noticed that you were able to assemble this where you work.
@OP
100TB eh? Yeah, back ups might be an issue Seriously though, the only thing that has a chance of backing up something that size is one of those wardrobe-sized tape libraries, controlled by Tivoli or something...unless you went and built an identical server and have all of its drives available as an iSCSI mirror or something - bonded GigE, the whole works.
As for the in-server redundancy...hmmmm....48 drives....I reckon 2 24-drive RAID 6 arrays like you suggested , and lose 8TB to parity. The number of drives per array will depend on what the Areca controller processor can cope with, which I've no idea about.
As an added precaution, I'd set up an account with an SMS gateway like Click-A-Tell, so you'll know immediately if one of the drives fails. E-mail tends to be kinda silent...

Awesome build man! I also would have suggested an SM board but one important thing! Don't forget your areca BBU! That thing is quite important! Also definitely go 2xRaid6 rather than 3xRaid5
I am still in shock and awe of this build log. Just the immense possibilities are staggering.
Glad that it is up and running, but like any new toy, don't stop playing with it till you get it just right!
Wow, amazing treadstone! And here I thought my 10 TB server was something to behold.
I am curious though what you are doing to avoid the Raid issues many folks are having with the WD 2TB drives? I know WD makes a Raid version of their 2TB drive that one would guess is an optimized (firmware or hardware) version of the drives you have.
Your lack of updates is disturbing.
He hurt his arm so i don't think he can move it into place to do anything with it.
Even though the all of the fans have a TACH output to measure the fan's rpm, unfortunately none of them are connected to anything that the CPU could access this information from. I am toying with the idea of building a custom made fan controller for this system.
I think 100TB will do fine for a little while. I am not sure if I would upgrade the system if larger drives would come along. What I would consider is to build a custom designed drawer style server system for 2.5" HDDs. Currently the largest size I believe is 1TB for the 2.5" HDDs. Once those get into the 2TB range that would be an interesting little project
I upgraded the firmware of the 2TB drives to a different version that is used in the RAID versions
Oh interesting on the fan controls....if you're savvy enough to make a custom fan control, then i say give it a shot! That would be a mighty undertaking...however I bet your ears would thank you! definitely interested in the custom drawer for HDDs, i've toyed with the idea of what i'll do when my measly 6TB system runs outta space. Considering the server could hold only 13 drives in total, I figure i'd use an extra case I have laying around and convert it. It's a piece of crap that I got for free; I could load up maybe 3 or 4 shelves running lengthwise in it and by my estimates fit approx 12 3.5 drives per shelf. Not bad considering all I would need is alittle plexi-glass, metal and backplanes!
Did the op already post the cost of this set-up? Wowza!!!
More info please. This is for the WD20EADS. Would you, or anyone know if it's the same for the WD20EARS.
Thanks.
nice build!
http://www.supermicro.com/xeon_3400/Motherboard/X8SIA.cfm?IPMI=Y comes with ombord gfx card.
Did buy this MB for my server. Lots of PCI-E slots
I actually drew up a schematic for a distributed fan controller already. The entire system would be able to handle 16 fans and have a USB host interface. I even threw in current measuring ability for each fan to figure out the power consumption/efficiency. It also has a temperature sensor per fan controller. Each fan controller would basically consist out of a small PCB that you would mount close to each fan to measure the temperature as well as control the fan. The design is based on or intended to be used with PWM controllable (e.g. 4pin) fans. I would just need to get my brother to write me an interface for the PC (e.g. a program that can run as a service in the background on an OS like Windows Server 2008 R2 or something similar).
Wow, i couldn't even fathom designing my own PWM board. I'm sure other people have said this, but you....probably could sell alot of those boards here and make some good side dough!
if you could have him write software that could be installed on a client machine that would be really sweet as you would be able to monitor the basic operation sitting at your desk without having to remote access into it
Sorry for the LONG
Thanks houkouonchi, I have looked at your builds in the past and enjoyed reading about them, so it's nice to see you like my little contribution too
"upgraded the firmware of the 2TB drives to a different version that is used in the RAID versions"
Can you elaborate on this further? How did you get this firmware, I thought WD likes to keep this secret?
Does that mean your WD20EADS is recognized as a WD2002FYPS or something like that? Can you do TLER on it?
are you willing to share
