some questions for chassis options

#1

Post by foxofinfinety » 28 Sep 2014 14:16

I currently use a NAS build mostly based on these recommendations, however, it is installed in a case that I already had, this reason for this is that when I build it it was either a less-then-great option for a case, or having to seriously limit the budget for motherboard/processor/RAM, since the case does work OK I decided it be better to just replace the case later on.

it's 'later on', so time to actually replace the case, the issues with it aren't really a lot, but still a fair problem.
firstly, it's a 4U rack-mount server chassis, which mostly makes sense since it is in a rack, but I need room for an extra machine, so I'd prefer to slim it down to 2 units.
secondly, while the case is large, it doesn't fit a lot, most of it is just open space (and fan's, it does fit a lot of those), that is, I have 5 drives and that is also as much as it can hold.

so in short the new case needs to provide more storage, while wasting less space.
the Supermicro SC826BE16-R920LPB seems a fair options, although an expensive one, but I have a things with it I'd like to make sure will work out well, especially since the chassis comes in at over 900 euro.
in essence this case does what I want, it's 2U and holds 12 drives, which gives me the room I'd need for the other system I want to add and I can double the drives (and then still add 2 more).

however, a other system I build uses a 'brother' of this chassis, the Supermicro SC825 TQ-560LPB, and I fear a problem I haave with that, will also occur with the SC826E16-R920LPB.
the problem is that I can't connect the RAID controller, the SC825 is used for a windows based server so it needs hardware raid, and for that I have an IBM M5016, and the NAS might get M5015's.

yet I can't find a cable that I can get from the controller to the drives, I can't use straight SAS connectors as then I'd have to go through the chassis cover, but all angled cables I find go to the right form the controller (seen from the front of the chassis), and then they'd have to go through the air duct.
while the M5016 and M5015 are different in features they are identical in shape and size, if the cable doesn't fit for one of them, it won't fit for the other either, and the differences between the cases are also minimal, so my problem now is, will it fit as far as cabling goes?
and if so, does anyone know how to do the cabling from the controller to the drives in that chassis?

separate from that, a other issue is processor cooling, I use a Supermicro X9SCM-F with an Intel Xeon E3-1230v2, right now I use the stock cooler, but the SC826BE16-R920LPB uses forced-air cooling, so I need a passive heatsink for the CPU.
but I haven't been able to find a lot, does anyone know a good passive heatsink to use in combination with that case?

I am a big fan of Norco cases. I use the 8 drive 2U case a LOT and love it.

You will need a side blow fan like this, however.

Also two of these cables.
