ML10v2 Drive Cage

Recommended Posts

LoneWolf

Well, I ordered the backplane for my ML310e, as the eBay vendor selling them is in my state, and is only charging $20 each for them.  I note that this part was the same for the Gen8 and Gen8 v2; I really think these parts will all work for the ML10 v2 as I continue to work on my system.

 

I need the backplane, SFF8087 cable (believe I have one sitting around) to go  from the controller to the backplane, and four hot-swap drive sleds (currently making offers on eBay as well).  It will be interesting to see how this goes.

 

The processor is already in and installed.  I have the system up and running, but will be upgrading to a 1GB cache module (also ups the cache data path from 40 to 72 bits), and the hotswap setup when the parts arrive.

Just waiting for my backplane and drive cage to finally arrive in Australia for shipment from the distributor. Drive sleds are on the way from the U.S. and should be here soon.

 

Can't wait to get it all finally done :)

My backplane has arrived.  I already had a MiniSAS to MiniSAS cable lying around (you will need this to replace the MiniSAS to 4-SATA breakout cable), so now I'm just waiting on the drive sleds.  I'm hoping they'll arrive before the weekend.  The 1GB cache module already arrived for my P222 RAID controller and is installed, so unless I go to a P420 controller, this is the final phase of my project.  The Xeon E3-1231v3 is also installed, as is the IcyDock ExpressCage underneath the DVDRW, and an Intel dual-port NIC.

 

One note: There is one place on the backplane that is fragile --well, technically four.  It's the spring-contacts that make contact with each hotswap drive sled to light the LEDs  when a drive is docked.  These are a little like the contacts on a cell phone's SIM card slot, and could be broken if one isn't careful.  There's one set right next to each SAS/SATA connector.

Also interesting --note that the drive caddys(I'm assuming those are hotswap, unless they're blanks) on the ML30 picture are different than the Gen8 hotswap ones.

Gen8 back view, this one's actually the 2.5" but similar (note the electrical contacts for the fingers on the backplane):

Finally, the basic Gen8 non-hotswap tray.  The metal pieces are bracers removed prior to mounting the drive.

They look like blanks to me:

Note those screws are not common and easy obtainable.

Unless you have gotten more HP servers and have a few of these screws in storage...

Well, my final parts arrived tonight.  Assembly in progress.

 

The docking sleds are a bit of a disappointment.  The metal springs at the outer edge make insertion somewhat difficult (requiring break-in) and the levers aren't very strong, making docking the hot-swap bays actually less confident procedure than the non hot-swap.  With the first bay, I was worried I would break it during the insertion process; I haven't opened the remainder yet (temporary interruption for dinner).  At first, I thought I was doing it wrong, so I removed the drive cage a second time to test docking the drives outside of the case, where I'm testing now.

 

We'll see where we're at in another hour.  I would like to see the construction to be stronger, especially on the drive levers.  However, I'm not sure that any of the sleds being marketed are HP OEM either; a lot of these may be reproductions, not bad ones, but maybe not HP (usually HP has their logo on everything, and I haven't seen that on any of the sleds I've seen advertised).

 

Note:  My drive caddys look exactly like the ones H00GiE and I posted.

Update:  Well, it's done.  Almost.

 

First - To anyone doing this project, one piece of advice.  The first time you mount your drives in the cage, do it while the cage is outside of the server.  If you have to adjust the backplane a little for the SAS/SATA ports to line up, or if you're just having issue with your caddys, this makes it much, much easier.

 

The caddys will need some break-in.  This is another reason why it's good to do outside of the server.  I believe that after they are docked awhile, they will likely slide in and out more easily, but you will probably have to work those metal spring clips a little the first time.

 

Second - On the backplane, it is completely possible to plug the miniSAS connector in wrong, with the locking clip facing the inside of the case (when it should be facing the outside).  I thought it would only fit one way, and found otherwise when my rig's bays didn't light up and the RAID controller failed to detect the drives.  :wacko: Fixing that took care of it.

 

One of my caddys turned out to be defective --that is, the lights aren't working, meaning the ribbon cable, or the contacts, or the IC chip up front is bad.  I just sent a message to the seller to get an exchange.  The drive still works, but of course, you know I want all four cages to have the beautiful circles that cycle clockwise.  There's also a blue LED that comes on at initialization briefly, and a white LED under the red button on the cages.  The circles are dual-color green/amber, I'm sure for good drive/failing drive indicators.

 

My metal drive cage has two stickers that say "Non-Hot Plug" on the inside.  It's just for warning; the cage is the same as the one in the hot-plug, just without the backplane and with different cages.

My cage and backplane showed up today :)

 

Just have to find some time to put it all together and take some pictures. It's been running like a dream so far, and I didn't really need to get a hot swap drive cage, but now all drives in the chassis will be able  to be changed from the front without having to open up the case.

I have pictures; I'm just waiting for a report that things have been fixed so that I can post them.

Well, some kind of complication today. I installed the cage, drives, and sleds and there appears to be no power to the cage. In getting ready to post this message I noticed that LoneWolf's backplane is slightly different then mine. At the top of each slot on my backplane is a little black plastic box with circuitry inside and no fingers for the sled to contact. The drives did not show up in the smart array manager either. So ended up putting it all back to stock and working again.

 

Now I'm wondering if I ordered the wrong backplane or if was shipped the wrong one. I'll post a pic shortly after I get back from an errand I've got to run.
