What MB has 24 RAM module slots?

If you want amusing, note that today, a 16GB registered is about $100, but a 32GB registered is about $500. I'm looking strictly at Supermicro tested parts here and wholesale pricing, retail's ... more. And the 32GB is only available as a DDR3-1333, HMT84GR7MMR4A-H9 ... and for a real gut-puncher, Supermicro recently bumped the specs on boards such as the X9DR7-TF+ from 32GB to 64GB modules, which allows for the possibility of a whopping 1.5TB of RAM on that board, but no candidate tested modules are listed.​

Oh, I hate it when someone lockes a thread and there is so much more to say and discuss. :p​

So, 1.5TB =1500GB/64GB modules = 24 RAM modules. What motherboard are we talking about jgreco that has 24 RAM slots on it? I think I have seen 12 on a crazy server board but not sure I'v seen 24 yet.​

The one I mentioned in the text you quoted.

Also
• X9DRE-TF+
• X9DR3-LN4F+
• X9DRi-LN4F+

and 5 others if you like to check their listings.....

At only $675, one in on my xmass wishlist! Specially for that dual 10 gigabit nic!

Oh , well that one that jgreco mentioned I missed the specs since the specs tab on Newegg was empty and the picture was such a small thumbnail I couldn't see it. I was thinking these MB's had 4 sets of 4 slots not 4 sets of six. Just didn['t look close enough and not I feel stupid so go ahead and delete this thread.;)

There are some caveats, such as only 8 slots per CPU being usable at full speed or limited by type (there's a whole manual documenting the ins and outs). 8 16GB modules per socket is the best you can do at a reasonable cost (128GB for $1000ish with a single CPU).

But when you start looking at the individual part cost for an E5 board, Intel dual 10GbE, LSI2208, etc, the price is attractive.

Note that the 2208 isn't a good controller for FreeNAS but is totally awesome for ESXi.

I have used the LSI2208 + BBU as DAS boot and datastore for ESXi in RAID1; since our VM's are mostly on SAN it is mostly just fast scratch space for VM builds. But I also threw a VMware virtual disk attached to FreeNAS on it which behaves as a very fast SLOG device. Since it is backed by HDD, it has virtually unlimited write endurance, and with the RAID write cache and BBU it has very low latency.

................. the price is attractive.

Says the Corporate enterprise who need or would even think of needing a $912 MB or geek that has more money than God.

I read where FreeNAS also works perfectly well as a SAN or NAS/SAN

The board can be had for much less than $912.

As far as VM storage goes, I've been really anxious to try FreeNAS out for the purpose, but since we passed on it a few years back due to 1531 and other issues, I have to wait until I can reasonably justify it. What I really want is a few terabytes of reliable storage that doesn't burn hundreds of watts. Pretty sure the Avoton with 64GB and maybe 256GB of L2ARC, and eight 2.5" drives mirrored and striped, plus ??? for SLOG is the ticket. Problem is I'd love it in 1U but I'd also love 10GbE or at least quad 1GbE, so there's some conflict there. Also some question as to the reliability of the AsRock board.

So I'm real tempted to just get another X9DR7-TF+, put a fast proc on it, and call it a day.
