Who the thinks about file sizes in terms of bits? Not me anyways.

Eh, since drive throughput is measured in bytes, calling out network speeds in that context with the same unit is valid, IMO. Makes it easier to compare.

Network speeds are given out in bits. Using bytes for networks just muddies comparisons. But if you're discussing file transfer speeds without specific concern for network speeds... Okay, this is getting silly.

Combat Pretzel posted:Eh, since drive throughput is measured in bytes, calling out network speeds in that context with the same unit is valid, IMO. Makes it easier to compare. No, because you'll always need more bits per byte to transfer over a network because of all the protocols overhead so you're not comparing the same things. This is also why in networking you always commit to a bitrate, not a byte rate, because this way you measure/deliver the actual network speed (typically at the layer 2, Ethernet) and nothing else. Anyway, sorry for the digression. I just like bits.

I dunno what you guys are talking about. mIRC shows me the transfer speeds in characters per second, isn't that what everybody uses?

I'm considering switching from a FreeNAS box with Plex etc. to an actual rack server (like this http://www.ebay.com/itm/192287543518) with Windows Server 2016 so I can learn some more networking with VMs and have a little bit of transcoding power. I can get WS2016 Datacenter and Standard for free through my associated University. Is it worth using ESXi to primarily run Windows Server 2016, but dedicating a couple of cores and ~32 GB ECC RAM to a FreeNAS VM for storage so I can keep my ZFS datasets? Should I just switch over to something else? Am I thinking about this completely wrong?

What are you going to store your data on? Those R610s only have 6x 2.5" drive bays, and I'm guessing your current fileserver doesn't have 2.5" drives. Also, those E5500 CPUs are old. Might actually have support issues running latest-version ESXi on it.

It can't be emphasized enough that rackmount gear is loud. E: and 1U is typically the worst because the fans are tiny and spin at like 10K RPM to make up for it, and all the air is being forced through cramped spaces with lots of little sharp features that make great whistles. People who work in data centers full of this stuff legit need to wear hearing protection, but even one machine on its own can be pretty bad.

I bought one once from eBay for $50. It was sitting in the basement. It was so loud, that during the night I could hear it from the second floor. After a week I had to turn it off. It is not sustainable unless you have proper room, and is far away from people.

If you are thinking of rackmounts for home use in any manner I would strongly suggest starting at 2U and larger exclusively. Otherwise, you can probably do 90%+ of the what you'd need for Cisco certs up to some intermediate point using just a couple tower machines that support VT-X which is basically everything on Intel and AMD in the past 5 years.

Ok so I replaced NAS4Free/FreeBSD with CentOS. I managed to import and update the pool. I can browse the files after import as expected. Very pleased. However, after a reboot the dataset isn't there. My pool is there (at /mnt/pool1) but none of the dataset inside. I did enable the zfs.target service. If import again it works fine. Is there something I missed?

Yes, I imported by id ("zpool import -d /dev/disk/by-id pool1"). I even re-exported and imported from CentOS but still no luck. Is there a log I can find somewhere? I couldn't find any.

Yeah, 1U stuff usually has much faster fans or uses squirrel cage style blowers. 2Us and 4Us are much quieter, or Tower servers are even quieter.

So I'd be better off with something like this: http://www.ebay.com/itm/Dell-PowerE...9cAAOSwBp5ZsDdP These ones have 8 2.5" drive bays but I might be able to find one with 6x 3.5" (the other config for R710). What's an option to mount 6 x 3.5" drives externally in a rack if I do get stuck with 2.5", or is it just not worth it? or http://www.ebay.com/itm/Dell-PowerEdge-R710-3-5-Virtualization-Server-2x-2-66GHz-X5550-32GB-iDRAC-/172795484780?hash=item283b69da6c for a little more. I'm looking at local listings for silent racks -- alternatively I can run it to the basement. Eventually I'd like to get a low VA rack UPS, unless it's considered immediately necessary.

I've got a Lenovo TS440, highly recommended. It is quiet, has plenty of drive cages ( I installed 4 3,5 drives in the server bays and 4 2,5 SSD drives in a 5,25 caddy all hooked up to the Lenovo branded LSI SAS card) and it is power efficient. Things that do suck, it goes to 32GB RAM and you need to buy the drive cages separately, I just Ebayed them from China. And you need to be careful of the one you get, I've got the 4/8HT 1245 Xeon with the SAS card which seems to be the best one you can find. It idles at 30 Watts or something.

Do those WD EasyStore shuckable units go on sale at Best Buy once a month or at any other sort of regular pace? All of a sudden I need to upgrade my storage...I'll wait a week or two if there's a good chance they'll be on sale again, otherwise I'll just buy something now.

I believe WD were having retailers get rid of old stock of EasyStores as WD just launched a new version (which obviously is not on sale).

Glad you were able to take advantage of it. One thing I've learned since that post: The white label drives seem to have an important difference that I didn't notice at first: they don't spin up when plugged directly into PSUs. But - they work fine via Molex->SATA converters. I found this out when I was doing final cabling for my build; my single white label didn't spin up; I googled around and others have seen this too. Perhaps they detect the presence of the 3.3v pin and prevent themselves from spinning up as anti-shucking protection.
