Great opening post. It sadly makes me feel uncomfortable, but it's still a great opening post.
"Everywhere" i go people keep telling me that FreeNAS in some old hardware they had laying around is a much better alternative then some of the shelf home /small office NAS. It's (a lot) cheaper, it might use slightly more power, but since it basically was free, it's going to take a while before the cost is to the of the shelf NAS advantage.
Now, i've been using a HP DataVault X310, and a ReadyNAS NV+ (gen1), and they still do everything i need them to do. But the space is getting small. Yeah, admittedly the NV+ is a bit slow at torrents, but hey.
So i started looking around, again. Trying to figure out what i got laying around at home. I've been at this before, and never really got of the ground. Well, to be honest, i was looking around for stuff to build 2 things, a new Smoothwall system, and the possible NAS. The firewall is a bit more urgent, so i finally got off my ass. I found:
512-8192 MB DDR2 RAM, in different flavors and speeds.
Intel Core 2 Duo E8400 (65w TDP)
Gigabyte EP45-DS4 motherboard with:
2x Realtek 8111C 10/100/1000 LAN
1 x PCIE x16, 1 x PCIE x8, (Physically a x16 slot) 1 x PCIE x4, 3 x PCIE x1
1 x PCI
AMD Phenom X4 9850 Black Edition (125w TDP)
Gigabyte GA-MA790FX-DQ6 motherboard with:
2x Realtek 8111B 10/100/1000 LAN
2 x PCIE x16, 2 x PCIE x8, 1 x PCIE x1
2 x PCI
AMD Phenom X3 8550 (95w TDP)
Asus M4A785-M
1x Realtek 8112L 10/100/1000 LAN
1 x PCIE x16
1 x PCIE x1
2 x PCI
Integrated ATI Radeon HD4200
Where a GFX was needed i used a Radeon HD5450
All systems were tested with a Intel PRO/1000 PT Dual for a minumun of 3 gigabit ports total.
The C2D i dropped the vCore & clock on, ending up with a 1.2Ghz 2GBram system with 4 gigabitports at 60w idle, and 64w full load. Crazy, only 4 watt between idle and full load, but that will do for the firewall.
So, i got the two other systems. Since i was testing stuff out, i found out they could both be clocked as low as 800'ish MHz, but the X4, which i expected to be a good low volt candidate, wasn't, and the X3 could run at full speed at the X4's minimum voltage, and at 838-1100MHz on 1.075v. Ended up setting it at 1100 on the ASUS M4A785-M for a system total of 75w idle, and 87-88 full load.
At this point i realized the Firewall would be the C2D, and started looking at my 2 AMD systems in a bit of a different light. Which one would be the best NAS ? The ASUS, and it's single meaningful PCI-E slot seamed less attractive then the GA-MA790FX-DQ, so the X3 would have a new home. The slightly "fancier" motherboard drew a couple more watts, but over all it wasn't that bad. Started looking around for controller/RAID cards. Based on my findings, it looked like i was getting a Perc 6/i, leaving room for a H700 in the future as the "next" upgrade, and stick Windows Home Server 2011 on it. It would end up idling at around (now) 85-90w. Full load would be somewhat dependent of the drives of course, but this is the bare minimum.
So, i started comparing with FreeNAS since that was the raved about alternative. It IS free. And it uses cheaper controllers, which is a bonus. But then came the kicker. Where as i already have the motherboard, CPU, and all the memory to make the base of the system for a WHS2011 system, i apparently need all new hardware for FreeNAS to really be a viable alternative. This was my "WTF moment" where i was thinking "but, what about all the system based used hardware people are talking about?" Reading a bit more, i more and more realized that even if i could make it work on "old used hardware" i wasn't going to get away with having dropped the clock, and hence minimizing the power the system use. Scratching my head, and trying to remember. Bone stock, no storage drives, 143w, i think the system hit at full load, and 98 idle. Adding drives to that...
The X310 is at about 65w full load, i could run 3 of them, for 12 drives before the power bill is about equal. The ReadyNAS at 29w idle, and 43w full load is even worse, and unlike the X310 it provides protection against one failed drive. (Where as on the other hand, the x310 only loses whats on the failed drive/drives)
I can compete with these figures on a used system based of WHS2011, but it doesn't seam realistic to try and do so with FreeNAS. Ok, so, i cheat slightly, i already have a 12buck license for WHS2011. But even if i add that to the price of a Perc6/i, and compare it to a ServeRAID M1015, at best it's going to come out equal. I have to push the clocks back up, i might even have to run the X4, thats even worse for the wallet, not to mention the noise, and i'm still using old hardware, a none ECC configuration, with not enough memory, in a way thats not really recommended. Actually, the only system i ever had, that would have been "right" for something like this is a Compaq DL350 G5, and it's idle consumption power was well in to the 230+w.
The obvious issue here seams to be that the FreeNAS system design simply isn't aimed at me, unlike what proponents have been telling me. And the opening post here REALLY made that clear. It's a shame, but it's also saving everyone a lot of grief. I'm going to keep watching this forum, one of these days someone i know, or someone who wants to pay me, might need storage, and at that point they are paying the bills, and buying new stuff regardless, making this a much more valid option.
If there is something i'm missing, that might make my reasoning invalid, feel free to point it out, here, or in a PM. But my main point isn't really about FreeNAS, it's about the opening post. It's a great post, and should be a must read. It might have deterred me, since i feel that i might be better of using a low watt system, with a "smarter" drive sub system to do the math for me, but it's definitely a great post.
B!
