@Falzo - need to be a little careful with that. Unfortunately my VPS got purged, I got it to 5 x 100TB before my test was cancelled as 'excessive'.
But it worked and performed great until then. 500TB should cover most peoples
pornISO collection, so we'll have to wait until someone gets close to that and run a new test with a couple of PB.@MarkTurner thanks for sharing those infos, do you have any kind of information regarding prices to expect for that range or some ETA ? ;-)
@Falzo - HA-KVM based StorageVPS are now available:
https://cc.delimiter.com/cart/cloudstorage-vps/
I still prefer time4vps vs HA-KVM
No one can guarantee everything working until something broken.
I had to cancel a VPS with them as internal transfer speeds between 2 of my 2TB storage VPS didn't exceed 200KB/s for close to 12 hours while moving some data around.
When I tried uploading some files to other servers that I had initially downloaded the same backed up files from, the speeds were more or less the same. A far cry from the 400mbit connection they advertise on their website, and later confirmed over a support ticket.
I tried everything from FTP /FTPS/ SCP / SFTP / rsync, but the speed simply wouldn't go beyond 200KB/s. What surprised me was that I received sustained transfer speeds of at least 10MB/s while backing up (Downloading) the data to the storage server from other servers that I have in EU.
When I raised a ticket, they simply responded that the issue was probably due to IOPS restrictions. Had that been the case, it should have affected the download speeds as well, right?
Anyway, long story short, my experience wasn't all that great.
I am down to one storage VPS now, and have no option but to keep it for another 2 months, as they apparently can't refund BitCoins (BitPay ALLOWS refunds, when initiated by the Merchant). https://support.bitpay.com/hc/en-us/articles/203324093-Can-I-issue-refunds-directly-to-purchasers- | https://support.bitpay.com/hc/en-us/articles/203411523-Can-BitPay-refund-my-order-
I'd recommend you pay a little extra and look elsewhere for backing up your data, unless you can afford to wait for a couple of months to restore your data from a backup server at 200KB/s.
@time4vps I'd like nothing better but to see you fix the issue, and maybe stay as a customer. Afterall, what is the point of advertising 400mbit port speed and 8TB of bandwidth when it simply can't be used or reached because of superficial bottlenecks and restrictions that seriously inhibit the usability of the service that you advertise and sell?
Your price point is pretty effin good, but the implementation left a lot to be desired.
Maybe it was just an isolated incident. But, after opening a bunch of tickets and observing a rather nonchalant support team respond casually and still NOT resolve the issue, I have my doubts about it.
Hello, we will contact you today regarding this incident. Our goal - happy customer, nonetheless, we will try to find an acceptable solution for you.
Phew, $193.20 for 10TB.. you can get 10TB ZFS netto for 50 EUR at https://www.transip.be/vps/big-storage/
FYI, the billing cycle box does not update:
@time4vps I have already re-opened and replied to support ticket #11219407.
I have also submitted results of a fio benchmark that clearly displays the problem of throttling at 200KB/s and 50 IOPS on your storage boxes, thus confirming and substantiating the throttling issues that have basically rendered my 2TB storage VPS on 400mbit port with 8TB bandwidth useless.
Regardless, I really look forward to hearing from you, and hopefully work this significant issue out ASAP.
thanks! so price point stripped down is $4,80 per (additional) 250 GB. can you provide some information on that high availability?
after all it seems somewhat competetiv to something like additional hdd space within ovh public cloud (40 € per TB vs $19,20) but less on other brand like transip or dedicated servers from hetzners auction and such (which indeed aren't exactly comparable, just to mention).
sorry to say, but at $60 for 3 TB, I'd rather go with hetzner or soyoustart (at least raid1) for my backup needs...
sadly most storage products come either with real HA at an accordingly higher price tag or without any redundancy for low cost.
it's hard to find suitable products in between. like cloud hosted 4-5 TB in a ZFS or Raid 5/6 setup for not more than $10 per TB. maybe delimiter will introduce their new product range on black friday with a smart and generous 55% lifetime coupon? ;-) ;-)
(probably need to sign up with delimiter though. just to test and play around. uh oh... have to resist...)
Single box vs Full HA
That would remove the HA storage by doing that. There was a 'cloud' provider in Germany listed on here recently who's ZFS backend went pear shaped, clearly that took down everything because there was a reliance on a single unit.
Leaseweb had their various cloud meltdowns with their non-HA storage and I think even now its NetApp (good product) but not HA.
Black Friday will being some storage offerings, there may even be some non-HA offerings for just 'cheap and nasty' storage.
@time4vps I haven't heard from you yet, and my support ticket still hasn't been answered in over 15 hours.
I have started to wonder whether my data is being held hostage, as I am unable to transfer it out due to the ridiculous rate limits on my storage server, or speak with anyone who can actually do something in order to sort this out.
I'd really like to know what, and where the hold-up is. Also, a straight-up answer about the ETA, or possibility of this issue ever getting resolved would be highly appreciated.
@K4Y5
I've problem since yesterday I only able to push 500 kB/s
@time4vps care to explain? or we need to move to somewhere else?
@time4vps It has been over a day since I opened a ticket asking for you to explain and fix the unrealistic restrictions placed on your boxes that essentially make them UNUSABLE, or refund the complete amount that I have paid you via BitPay.
BitPay apparently allows merchants to issue refunds through a simple refund button now. I am sure other merchants can either verify, or correct me in case I am wrong.
@time4vps I had sent you the complete output over a ticket yesterday as a courtesy, but it has neither been acknowledged or fixed till now. Since no one @time4vps seems interested in sorting this mess out, I am going to publicly post the results of a benchmark that I ran on your server yesterday.
WRITE: io=12588KB, aggrb=209KB/s, minb=209KB/s, maxb=209KB/s, mint=60025msec, maxt=60025msec
@tommy and other LET members having storage boxes with @time4vps can run similar queries or use DD with non standard parameters to find out the real world performance their heavily throttled boxes offer.
I am pretty sure that they use compression and zero discarding to inflate results of standard benchmark, and make performance seem way faster than it actually is.
I haven't run into that yet, just pulled from the server at 81Mbps and pushed at 18Mbps from my home connection in PA. My home connection is 75/75 so it more than maxed what I pay for down, but couldn't do it going up.
Just pushed 86Mbps and pulled 92Mbps from Delimiter in Atlanta.
Hello,
Thank you, we have received your e-mails with pretty massive bash, false assumptions and threats. Nonetheless - we are working to offer you a solution and if you are ultimately unsatisfied with our services we will offer you a refund. Thank you for patience.
Even after this has been posted to LET, and you confirmed you will help the user, you still leave the ticket unreplied for 15 hours.
wait.. iops limit now is 50?
I'm doing a backup from online.net and apparently the download speed is limited to 1MB.
For storage server it is 100. If you see 50 than this means your storage server is limited due to constant 100 IOPS limit hit. In order to reset this - simply restart VPS. To avoid such situations use rsync command with --bwlimit Kbps option.
And we will help.
So there's a limit, but you can't actually do the limit.
Can't say I've ever been pulled over for doing the speed limit all the time.
Why not just make the limit 75 IOPS instead?
Not 15 hours. It had been well over a day since my support ticket went unanswered, after which I had to post my last response at LET.
My servers had been idling without any additional packages installed on it (except htop), and the standard tools and packages on the custom CentOS installation that your storage servers come with. So, I can't understand the reason behind throttling my box to 50 IOPS and 200KB/s.
You can check the server load graphs and logs for the same.

I had been cordial and polite in my support tickets till the point they were actually being answered and acted upon.
I am not an insolent or unreasonable person. But, there is an extent to which an individual can wait for proper resolution of an issue, or a definitive response from the support team.
As for the perceived 'threat and bash', it was clearly in response to not hearing from your support team after a day of THIS.
I agree that I might have been a little firm, and for a lack of a better word, in-your-face, in my last message. But, I have always been civil, and would like to apologize for the odd rant.
After you promised to contact me at LET, and didn't; I sent 3 replies to my support ticket over the next 24 hours which were never acknowedged or acted upon. After that, what was I supposed to do? You left me with no option but to follow up on LET/WHT as well.
It was only on the 25th (4 days after opening my first ticket, and 24 hours of patiently waiting for a response) that my tone changed a bit, as no clear resolution had been provided to me after having spent ~5 days exchanging 10 messages talking about the same issues over and over again.
As per your specific repeated instructions on 23rd, 24th and 25th, I tried rebooting and using --bwlimit with rsync on 23rd itself, but it didn't help either. The transfer started at 12MB/s, but speeds dropped to, and stayed between 190~250KB/s after a few seconds.
Had you outlined the service limitations earlier when I first mentioned the (minimum) steady and sustained download speed of 10MB/s that I received while downloading data TO your servers, while comparing it to the internal transfer speed of 200KB/s, I would have understood and worked on it with you. But, simply choosing not to respond to tickets for 24 hours, or follow up on your promise to work with me over at LET, was a little difficult to deal with.
At this point, I am done waiting for a resolution, and dragging this issue any further.
I'd really appreciate if you could please cancel the services and refund the total amount as soon as possible. I am sure at this stage and in my position, you would also prefer the same.
We already contacted you regarding refund.
Didn't receive any email alert. I'll just log in and check.
Oh wait, seems as if I missed some drama!
Didn't have those problems with my storage VPS over there, maybe I am lucky and my setup doesn't touch any of the limits...
Actually 99.3% of all storage server owners use services without any single problem regarding IOPS limit. But, such incidents as this help us to improve our services and we are more than grateful!
I checked out my storage server to verify outgoing transfer rates. Was able to pull 90mbps from ovh and Incero Dallas over.
Will run some more tests for incoming transfer. Maybe it was due to the particular backup/application workload of the person who had issues. (my attic/borg backups only write one chunk file at a time)
We can do the maths:
If its a standard EXT4 file system then the block size is 4KB
Its rate limited to 100 IOPS therefore 100 x 4KB = 400KBps max disk throughput
Running FIO on the VPS:
Confirms 104 IOPS and 419KBps
QED
So assuming the network is uncontended, the fastest speed you can get dumping data direct to disk is 3.4Mbps (419KB x 8).
