Looks great - I like their website.
Umm, this is super fast?
This cant be ssd... raid 10 enterprise sata disks..
Either it is satat raid10 or if it is SSD, some one is abusing or badly oversold.
+1.
I get 182mb/sec on a somewhat-heavily-loaded server with 7.2k enterprise SATA drives on RAID 5.
/me shrugs
it's fast.
199mb/s is only slow if you like to stare at the numbers. That's going to accomplish any task suitable for shared resources.
TIL, anything below 100MB/s is considered slow and oversold by LET standards
Honestly, if I get 60MB/s + I am completly satisfied, as long as it is stable. 60MB/s in my eyes is enough for everything and never had a problem with working with slower IO. Actually my main site is hosted on enviroment that is around 60-70MB/s, along with other production sites as well and I think it is working fairly well.
As not all of my nodes are in RAID 10, we have around 70-100MB/s on some of our nodes and none of our users actually complained, so I can not agree with that standards at all.
50-60mb/s constant is perfect for average users.
Here is some results of the 128Volts plan.
CPU model : Intel(R) Xeon(R) CPU E31230 @ 3.20GHz
Number of cores : 1
CPU frequency : 3200.000 MHz
Total amount of ram : 256 MB
Total amount of swap : 0 MB
Download speed from CacheFly: 55.2MB/s
Download speed from Linode, Atlanta GA: 9.84MB/s
Download speed from Linode, Dallas, TX: 10.5MB/s
Download speed from Linode, Tokyo, JP: 4.47MB/s
Download speed from Linode, London, UK: 10.5MB/s
Download speed from LeaseWeb, Haarlem, NL: 19.2MB/s
Download speed from Softlayer, Singapore: 6.75MB/s
Download speed from Softlayer, Seattle, WA: 15.3MB/s
Download speed from Softlayer, San Jose, CA: 33.5MB/s
Download speed from Softlayer, Washington, DC: 33.8MB/s
I/O speed : 304 MB/s
edit: I see that sometimes when I run this it says my cpu frequency is 1600mhz and the I/O speed is down to around 190MB/sec so looks like there is some CPU throttling or something.
Please don't be so extreme
The sequential speed you get with dd is only one side of a good I/O. Experience shows that average use don't need more than 30-40MB of sequential speed to behave fine if also latency is constant and random read/write are good.
Also most of the sequential speeds test are influenced by various layers of cache so asking for an increase of sequential speeds you are forcing providers to tune systems to respond better to some tests but worst in real life usage.
I report you a real experience. Some of you know we have some nodes which use one of our old fiber channel san as storage. The maximum sequential speed I can get from the san is 90-95MB/s, looking at your statement this would be sub standard for you.
BUT if you put on this node 10-15 heavy torrenters (as it actually has), sequential speed stay into the 70-90MB/s range AND more important latency stay low and constant and other users/application on the node run unaffected.
The same number of torrenters on a traditional raid array with a dd of 200MB/s make latency suffer much more with spikes of >100ms... So what do you think it would be better?
:P
It's SATA not SSD, sorry for the confusion. I am assuming you are on the Chicago node, after the upgrade, our dc stuffed up the network port, so it's now a 100Mbps port instead of a gigabit port which it was before. We will get it back to gigabit soon and you should be seeing speeds of ~60-70+MB/s.
this ia already pretty good... one way you can improve is by getting some xen in the mix
Everything should be working okay now
We're looking into different types of virtualisation but we need to gauge interest first.
