Could you try this for me please? I don't really want to order them and find that limitation :)

I don't have too many big drives, other then 2 1TB hitachis that are failing but still work, so I might try those to see if they at least see as 1TB.

As for openfiler, I just heard of it and was curious to try it. Though I'm debating on maybe trying out FreeNAS as well. The nice thing is this is not production so I can play with it without being down.

Load on iSCSI for me hasn't had any troubles, but ya the multiple reboots kind of pisses me off a bit. I liked that I can install it on a 4gb usb drive and not have to use another drive for the os.

Yeah it may have been some hardware incompatibility or something, it would reboot randomly and I'd just hear it coming back up and do it's little beep chime, and think "shit, all my vms just went down again"

That was the one thing I really liked about FreeNAS, I had it installed on a 2GB usb drive, openfiler would not install to it very easily, there was some method you could use to do it manually but I ended up just throwing an old ide 40gb in for the os. The initial setup was more involved with openfiler, but after testing with both, the choice was very very easy, at least in my case.
 
I found the install was fairly quick but I do wish it was easier to do it on USB, I did not try mind you, but did not find much info on it other then hacks hacks hacks. The hard drive is something that can fail, a USB stick is fairly reliable if not really written to much. Come to think of it, something that would be awesome is sata to usb, it would treat a usb device like a hard drive, great for appliances.

You could always just use Compact Flash to SATA.

There wouldn't be much hope for the data if there were actual drives in those trays; it'd be a sh*t show. :p. Speaking of infotrends, are yours still for sale? I'd lIke to buy two of the 24 bays for our lab. Ours are still going strong, but are fairly limited by the dual u160 interfaces.

Managed to get iSCSI to work. Pretty sweet. I'll be using this in Linux of course, just wanted to see if I could get it to work in Windows as well.

I also decided to try something different with my setup. In my past pics, I was only using the two SAN enclosures. I forgot about the fact that these can be daisy chained, so I figured I could only use two at once given I have a dual fiber card. Well I was wrong. Fired up the bottom two and I can see em as well.



What I did is daisy chained the top two on one port, and the bottom two on the other port.

Also my two raid 10 arrays are done building. Took a good 2 days. lol.

I also tested a power off/on to ensure everything comes back online, and it does... faster then it did at work when using the IBM SAN head/setup. It's actually kinda cool to watch it come online as it fires up one drive at a time.

In another topic, anyone know where I can get enriched uranium and gallons of heavy water? I need it for an indirectly related project. :D

The bottom two will be strictly for messing around so I probably wont even build any arrays. I'll also test out if they will take 1TB drives. I don't have anything higher to try with unfortunately though.

Awesome- thanks! I looked up the spec on these things and they look pretty deep... what is all the space filled with behind the drives? Do they draw a lot of power and make a lot of noise?
 
Trying to get into the mood today to clean up the rack and wiring, maybe finally mount the 1131. If I do, I will get some new updated pictures up.
 
I'm changing my wireless back to Skynet! :D It was called that for a while, but I changed it to UmbrellaCorp last year. :)

Tempting Fate you say? One of the Guys in sales in the building next door is named John Connor. So I'm prepared to help him lead the human resistance against the machines should the need arise. :)

It actually seems like they have some empty space, but the PSU units are very long and they also have two blower fans. The ESM cards are not as deep as the PSUs but guess with the backplane and wiring it adds up to using up a decent amount of internal space.

Just tested power usage now with the 4 enclosures turned on:

3.2 amps when idle (drives not spinning) Not sure why it uses that much power on it's own.

8.3 amps when drives have all spinned up.

Voltage reading at that power bar is 117vac so that comes up to 971 watts. To give an idea on heat, well imagine a 971 watt heater on your rack. :D

As for noise, my 1U Dell PE1650 firewall overpowers any noise generated by any other of my equipment so it's hard to tell. Since it's old the fans do have some squeek and grind noises to it but nothing major. Probably not something I'd want in the same room I'm working in though.
 
are you sure it uses that many amps? Thats quite a bit, we get about 25 amps total per rack.
 
Yeah I put a clamp on meter on the hot side. It does seem quite high especially for idle. I've used that meter before for other more predicable loads and it does seem accurate enough. I'm not sure if it's true RMS though, I believe when they're not true RMS they tend to give slightly higher readings for inductive loads.

Keep in mind that's at 120v as well. I think they do support 240v.

They are indeed rackable systems, dual opteron 246 (old school). Microsoft donated two rackfulls of them to a neighboring lab at the university. I'm currently using them to host some old servers in esxi 4. I haven't tried to get the serial management to work however; the old age of these keeps me busy enough replacing dead psu's and management cards :D .

Lots of spares; half of these still work since they were donated two years ago.

Awesome andypress:

I've got a 3U Rackable 12-bay dual opteron 270 system on the way to serve as a NAS. Hope it's not a gigantic piece of crap. Have you been suffering a lot of hardware failures with those PSU's? Should I avoid using one?
 
We have quite a few of the 3U Rackables at work and they have been pretty good. A few drive failures here and there, but that is to be expected.

Sweet thanks! That's pretty reasonable. I'd only be looking at one enclosure... so 250 watts wouldn't bother me. Now I just need to know about bigger disks :)

I didn't get very far trying to use them for ESX as they don't have the VT thing you need to run 64bit guest operating systems. I am using one for my fileserver at the moment though and get on really well with it (nice and quiet, small and low power).

Never managed to get the management interface working.

A lot of the wiring shown here doesn't meet electrical code in the US. For example:

Calbing passing between floors needs firestopping in and around the ports that penetrate structural members. The cabling also needs to be suspended at each floor. You can find more about this in sections 800.3(C) and 300.21 of the National Electric Code (NEC). Hopefully, these are all CMR- or CMP-rated ables, per section 800.179(B).

What I started with.. The phone and cable service from the street.

Section 110.26 of the NEC tells us that access to the service box must be unobstructed. That 2x2 is in the way, and it looks like there's plenty of other clutter defeating this requirement.

Section E3305.3 of the building code says that plumbing can't be run above electrical panels. This gives an exception about plumbing above the structural ceiling, but it's clear that all the copper here is actually below the joists.

Skud said:
Not exactly an ideal installation....:p
Wiring3.jpg
Click to expand...
The "Neat and workmanlike" clause is found in Article 110, Section 12 of the NEC. It's unspecific and subject to lots of debate, but I think it's pretty clear this installation doesn't meet the intention of the requirement.

Skud said:
The phone has a "humming sound" you say?

NM cable must be protected. Here, it looks like it isn't. Protection needs to be provided because the hole is less than 1.25 inches from the face of the stud, leaving it unprotected. As installed here, a screw or nail through the drywall, then into the stud can penetrate the cable.

Skud said:
More runs.. I've tried to keep it as far from the AC wiring as possible.
Wiring10.jpg
Click to expand...
NM cable must be secured within 12 inches of every junction box, as specified in section 334.3 of the NEC. I think there's a box capacity issue here, too.

Bicycle hooks aren't UL-listed for in-wall installation to hold electrical wires; even limited energy communication wires. This is covered in NEC sections 800.24 and 300.4(D). Since cable TV wiring is involved, there are also relevant sections in Article 820.

Skud said:
Back at the home run.

NM cable must be secured at intervals not exceeding 4.5 feet. Close call, but the picture looks like there's only one staple for a pretty long run. This is NEC 334.3 again.

I see that Skud's pictures are hosted at a .CA site, so maybe the installation is in Canada. Most of the same requirements apply, and the relevant sections of the CSA should be referenced.
