hmmm...peak in July 2021? Interesting...that would be a first one.
I still think that we might be going for two peaks in 2021: first one in March-April, followed by a "valley" during summer, next, a larger peak in Nov-Dec (traditional time frame).

Something like 50-70K to 30-35K, then to 150-200K.

Sun, AIX... we're talking archaeology! 

I am sorry to say mine needed configuring when I got a new box, two drives had issues and were u/s.  I had 4 (two main and one backup of each one) and the two backups were not able to be seen.  The main drives were ok, fortunately.  Got a tech guy in in the end to check it and had to buy two new backup drives to get it going again.

Spark up the drives and just see if they mount ok - as long as you can see all the data- the worst case is re-back up.  If they don't, it's a pain!  You need to get into the Synology software (which sucks) to do and it takes forever to re-backup.

I now have a back up I make monthly of each 'primary' drive.  I just don't trust the NAS enough.   I had WD reds 4Tb in each slot.  It's only for main 'work' data storage, my desktop (Mac) backs up via Time Machine to a portable cheap drive.  If only NAS worked as reliably

when the grid goes down what do you do with your shitcorns? :-D reeeee

If you think an HP server is loud, try any modern ASIC miner. 

We heat one of our storage rooms with an L3+ and since then all our servers seem to run completely silent to me. Some people say my hearing is impaired, but I don't hear that very often.

I got one DS409+ and i only plug it in and switch it on when i need it (fifty times a year or so), to free up space on my work ssd(s), get old movies etc.
I bought it without disks, and because i knew how unreliable these are, i added four WD green 2TB hdds to the cart.
Two are used for mirroring, one as spare drive if one of the mirrors goes bad, one for backup of the NAS in case it breaks.
Most important, i reconfigured the hdd bios to disable power saving, which is parking the disk heads too often (after 5 secs was the default, iircc), and this puts so much stress on the drive that it would die in any NAS before even reaching end of warranty. Well, my data doesn't care about warranty.
To date, and the unit is about 17 years old now, i had no failures at all.
 
It would not be too hard to mirror drives and let them be read separately by mounting them into a PC, technically, but most every manufacturer is working with filesystems that are only readable when all drives and the data are intact. There were some controllers back then, i don't remember the name at all.
This would save a lot of trouble.

Pro Tip: Keep all (!) the hardware redundant.


If the damn things weren't so fucking LOUD. At least IBM xSeries delivered some realtively quiet rack servers, but all the HP, Sun and (IBM) AIX server hardware i've put my hands on so far were screaming loud.

when the next green candles come and when there is more talk/show about BTC on tv/radio and when you are asked about Bitcoin by your friends/relatives, you can send them this link so they can easily understand all the material behind BTC

and as for the number of pages here in this wo-thread, we are again slowly moving away from the BTC/USD price...

Yeah, server hardware is the way to go... HP is my choice too... many say HP is crap nowadays but they obviously haven't dealt with DELL, IBM, Supermicro and other brands. HP surely offers some weird solutions, some things don't work out of the box, sometimes buggy software, some driver/compatibility and update issues now and then but in general still way better than competitors.    

Bitcoins? Who said anything about bitcoins? I was thinking about different types of corn. But I'm sure you see.

No need to worry. In a couple of years they'll be so cheap, you can buy 10 of them, and they'll eagerly take care of all your sensitive data.

The big question: what is the price target given all this new info?

Oh yeah. Whenever I hear "give us your bitcoins and we will take care of it!" I think of an image like this.

Custom raid controllers are bad. In my limited and unhappy experience, soft raid controllers (as found in some BIOSes) are also unreliable.

N+1 is bad, too! Apart from the ugly performance, when one disk fails, the others are not that far behind, which exposes you to data loss. Also, resilvering (rebuilding the mirror when a new disk replaces the dead one) takes forever and stresses the rest of the array.

The KISS principle says the "best" way to have effective redundancy in a "single" device is a simple 1+1 mirror. What I like about zfs is that it provides mirroring as a high level software service, so the hardware/controller thing becomes a non-issue. The disks and controllers are turned into a fungible commodity, which is where I aim to be.

I wouldn't mind her taking care of some of my data.

Technically he is doing disk duplexing: Two disks, two controllers, two channels.

I always found custom raid controllers to be the worst possible idea: Not only are you reliant on the N+1 disks, you're relying on the controller not blowing a hole in itself and sinking everything. Bonus if you can't get a new controller/same version. Super bonus fuckage if the controller stores all the disk information in its eeprom instead of on-disk.

Seriously, if you are counting on a single cheap NAS it's better to give your data to Bowsette....



She'll take care of it.

Mirroring?
If you're going to build from scratch, I advise you to consider XigmaNAS, open source based on FreeBSD. That zfs file system is the shit.

EDIT - The mainboard died on me once, it was an AsRock, a little brittle IME. I had to get a new one, hard to find. If it dies again, I'll rebuild with some other cheapish brand (Gigabyte likely). Advice: don't skimp on RAM. zfs likes it, and it's put to good use.

Only once I had to recover a disk, it was from another system that died (disk was good in itself). Format was UFS. Plugged it in... recognized in no time. Copied the data over to another, mirrored zfs pool, reformatted the old UFS disk - which is still working as one half of a different mirror now.

Re: NAS

I've got (and sent to the bin) quite a few of these (Iomega, thecus, etc.) over the years. I need to store data and backups on multiple physical locations reliably and I was quite excited when these home storage servers hit the market ~20yrs ago.

Since I have all data synched in multiple locations, the loss of one of those NAS servers was never catastrophic, but a MPITA and great annoyance nonetheless. Some are hooked up to synch via 10Mbit/s line, 5TB take a while* to synch over such a link. Except two of them all have died meanwhile the very same way they did on heslo (it doesn't even need to be a black- or brown-out, a simple shutdown can kill these buggers too, and yes it's always the mainboard never something easy to replace like the power supply..).

These NAS most often have very low-end CPU and I/O and I found you get way more bang for the buck with used professional servers. I am somewhat familiar with HP servers, but I guess it doesn't make a difference and I would not want to recommend them specifically, but that's just the brand I am used to - YMMV.

Currently I could buy a used/refurbished DL380 G8 48G RAM and 14x1TB for 887 EUR from my supplier. This looks to me like a good price compared to all these crap NAS. On top of a professional raid controller, it has more RAM than most NAS, redundant power supply and I never had such a server fail on me yet the way these NAS tend to very often. And if a part fails, you can actually get cheap replacement parts everywhere and fast, unlike these NAS that are pretty quickly discontinued and replaced and if you are lucky enough to get replacement parts they are overly expensive.

Now I understand that not everybody has a 19" rack in the basement (though these can be had very cheap too :-)) or even a separate room to place a loud beast like this in. Still, all these NAS products that I have had my hands on over the years totally and royally sucked and gave me a very bad price/performance ratio. Avoid them if you can, maybe build something yourself, load FreeNAS or whatever, everything is better than these shitty towers of future misery due to data loss.

Enough rant about NAS, BTC doesn't mind where you store it as long as you have a copy of the seed on paper
