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:

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.

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.

OK, looking at the parts, I can see that my backplane is identical to LoneWolf's. Part numbers, etc., and the little black boxes at the top next to the connectors are actually covers that come off and the contacts are behind them just like LoneWolf's.

 

I'm wondering now if that is the reason I didn't appear to have power to the drives because the covers were keeping the sleds just a millimeter or so from being able to correctly contact the power contacts in the connectors. Drives appeared to be seated, but maybe they weren't.

 

Now I'm going to have to give it another go at the end of next week when I have some more time. Damn :)

 

On one side of my drive caddies you can see HP molded into them. Don't know if they are original HP parts though. I seem to remember the caddies from the HP ML350 Gen3 I was messing around with had very flimsy caddies also, so I don't think that is really an indicator.

LOL, I'm sure it will work this time (fingers crossed) now that I discovered the plastic protective covers over the contact pins. Very strange there wasn't some kind of marking or warning to take covers off before using. 

 

I guess I could blame LoneWolf for not mentioning them, but maybe his didn't come with the covers :)

I figures as much, your documentation has been great so I assumed when I finally figured out they were identical backplanes that yours must not have had them. Alls great now that I know what the problems is :)

Did the reinstall minus the protective covers today and same result. Can't figure out what the heck is going on. Maybe got a bad backplane. I'm going to leave well enough alone I think.

 

I might just trim off the bottom lip of the hot swap case so the stock power/data connectors fit and at least not have to pull everything apart to just change one drive. Can unplug it from the back and just pull it our from the front. At least that would be an improvement.

 

I've just ordered the backplane that uses the stock connectors. Don't really need hotswap. Just convenience when changing drives.

Well, it looks like linking pictures works again.  Let's see if this flies.  The one change is that all four drives in the IcyDock are now filled.

And, an image to show the connection of the backplane.  The two PCIe cards are my Smart Array P420 and an Intel Gigabit ET server NIC.  Anyone making the switch will need an SFF-8087 (both ends) cable to replace the SFF8087 <-> 4xSATA that is there; it just so happens I had one that came with an LSI RAID controller I acquired some time back.

LoneWolf, it was just plug and play with the power connector for the backplane? I don't remember anything being said about pinout issues, so I'm assuming my backplane didn't work because of some other issue.

It is just that.  There are three possible reasons yours didn't work that I can think of.  All involve the SFF8087 (MiniSAS) cable.

 

1)  The SFF8087 cable is loose either at the motherboard (or RAID controller) or backplane.  This can be touchy, getting it to click can take a bit of finessing.

2)  If the SFF8087 cable is plugged in the wrong way at the motherboard (not possible on the P222 controller, but it is on the B120i) or the backplane.  If so, things won't come up, though the server will power on, nothing's going to light and it won't find the drives.  Your picture looked correct on the backplane; the latch on the cable should be facing outward.

3)  You have a bad SFF8087 cable.  That'd do it too.

 

The less likely options would be if your drives aren't seated properly (I definitely had to seat mine with the cage and backplane outside the server the first time, they should be good from now on), or if the backplane is bad, but I'd doubt it, yours sounds new.  Mine looked new but was advertised "used" and came with no plastics as previously mentioned so it probably is.
