I've always wanted the 24 disk supermicro case.
so in May 2007 I built my own with three 5in3 trays in a tall case that could hold 4.
I've never really been happy with the setup.. the drive activity LEDs are not on the drive trays, but are on the edge of the cage. the trays are easy to slide in and out, but vibrate, so I use heavy grease to remove the vibration. Yea, each of the three 5in3 have their own fan, with two speed settings, and an over temp alarm, but the supermicro 5in3 are better. photos
anyways, Sept 2010 I tried again and ordered a new $400 case.
so that leaves me with:
$250
X7SBE MB two 133MHz PCI-X @ 1,067 MB/s each (PCI Express 4x speed)
$195
Xeon E3110 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core CPU
$204
8G ECC ram
$210 two
AOC-SAT2-MV8 PCI-X133 8 port SATA cards
$400
NORCO RPC-4224 case
$78 six
4 Discrete SATA to SFF-8087 (Reverse breakout) Cables
$7
4P in Molex 1 Male to 7 Female Power Extension Splitter Cable
powersupply with at least 6 Molex power connectors
two unused disk slots, but no expander GUID issues with SATA disks.
If I did it over today, an extra $23 buys one newer stuff and the ability to add a third 8 port SAS PCIe 4x controller off the south bridge.
$190
X8SIL-F Xeon X3400 / L3400 / Core i3 MB Dual LAN Micro ATX w/ Remote Management
$232
Xeon X3440 Lynnfield 2.53GHz 8MB L3 Cache LGA 1156 95W Quad-Core
$134 * 4 for 16G Registered ECC ram
$244 two
AOC-USAS-L8I PCIe 4x
$90 six
SFF-8087 to SFF-8087 Internal Multilane SAS Cable
Another idea for more zfs arc (system ram) are amd's G34 designs.
$265 H8SGL-F with ether kvm
$280 or
$516 8core single processor
$102 * 4 for 16G Unbuffered ECC ram
$134 * 8 for 32G Registered ECC ram
so what's better four 4+1 or two 8+2 vdevs?
The 4 center fan aren't too loud, sort of like the computer you had 4 years ago. Moving from 12v to 6.3v takes the edge off, but still noticeable. They won't spin below 5v. But boy, the two fans in the back, are nuts! In fact you can feel the gyro forces while you hold them. Dragging them down to 6.1v helps alot, but even then, they are still very noticeable and won't spin lower than 4.4v. The 1600rpm Scythe Slipstream is silent at 7.8v like the 1200rpm @ 12v.
The back planes are nice. The strain relief on power and sas connectors are soldered a second time after the wave bath.
The pleasant surprise was that one can shut off the air on unoccupied bays and mounting holes for 2.5" disks.
wonder what's going to happen next?
treadstone's proposal is the best for the community, but selfishly this is a replacement for a tri 5in1 disk theory that I was never happy with. My goal is to improve on it, not the the stock 4224.
But as a gesture we could do a baseline disk temp graph on the old
box doing a scrub and see how that compares to the modified 4224. In all
cases 120mm fans should offer more CFMs, we just need to balance how
much wattage we pump into the fans :-)
the marketing theory is
4 * 35.3 CFM @ 31 dB(A) (141.2) is less then 3 * 68.54 CFM @ 24 dB(A) (205.6)
and
2 * 57.2 CFM @ 44.5 dB(A) (114.4) compared to 2 * 88.11 CFM @ 33.00 dB(A) (176.22)
yea, two fans in the back... but to treadstone's point.. lets measure it because we realy don't the effect on deltaP.
A few notes from my build:
Most disk trays have little springs on the sides to stop rattling (my old 5in1 didn't and rattled badly, axle grease was my friend)
Norco "could" rattle because they wiggle in the slot, but I admit I haven't experienced it. Anyway, its easy to add four spring steel loops on the side.
The PS has 5 drive molex feeds, I use them all to maximize copper to backplane.
sweloop64 is correct, graphs from smart, a line for each disk.
I'll be ordering the Norco 120mm midplane, less holes than mine.
the brown/gold thing is a south bridge cooler (xmas gift)
X8SIL-F+x3440
that's a nice setup novadude! I showed you mine, now show me yours :-)
#!/bin/sh while [ 0 ] ; do /usr/ucb/echo -n `date +%k:%M` hdadm display | awk '{ if ($6 == "0K05") printf " " $7 }' echo sleep 60 done
Old case | New 4224 | |
Rise during scrub | 3° | 2° |
Delta T | 6° | ~5° |
Max T | 48° | 42° |
Resting Max T | 45° | 40° |
So with 5 120mm 1200rpm Slipstreams there is an overall reduction and increased control for the 10 black disk. The new green spare is at least 5° cooler than the black drives too. I can hear the air seperate from the 3 inner fans when I put a cover over the backplane to midplane so there is a slight deltaP issue. We do have a max operating of 60° we could decrease the flow and take advantage of the delta from ambient. naaa.
The first hr is steady state with all five 1200rpm slipstream fans. The second hr is with the case top covering the mid plane and back plane to simulate no rear fans. The third hr is with no case top. and the last two hrs are with the case top replaced. It looks like one needs to run each state for over 2 hrs, (looking at the scrub graph, perhaps 5hrs) but it give us an idea on fan options.
