@prometeus : what is the pros and cons of using RAID 1 SSD compared to RAID 10 SAS Drive?
Well, I consider this setup more balanced for the E3 architecture (1 socket, 16GB of ram) and the low density of VPS on the node we plan to sell.
Consider that at least you would need 4 disks and a raid controller versus 2 x 240GB SSD disks in software raid in our setup.
We will have 6 x 600GB SAS drives with the E5 (dual sockets, 64GB of ram) where the cpu and the ram allow you to increase the number of VPS you can put on each node.
How about the disk I/O speed?
Both setup can sustain very high load and speed.
SSD in some tests done with debian and proxmox did >400MB/s sequential write within a VM with virtio. On the final solusvm setup speed was 300MB/s.
We expect these performances to stay high even when the disks are full.
On the other hand SAS (as other disks with moving parts) give you best results when they are not full, but performacens tend to show a bit when heads need to move back and forth to get/write data.
So SSD in RAID1 vs SAS in RAID10 don'r show immediate differences. But this change if you have a raid10 (or raid0) with SSD disks...
Just for fun I tried a 2 disks raid0 and I got >500MB/s read speed :-)
@prometeus what kind of IOPS can we expect? Thinking of getting one of these for MySQL
from one debian vps:
@prometeus : btw, you should also add 'iperweb' tag to this post and maybe your previous post.
So, people will be easy to search information/post about your host
updated the tag in this post :-)
Very nice random i/o disk performance and CPU power, this is one of my fastest LEBs.
I am now using it as graphical VNC remote desktop with Chromium browser, Libreoffice and some desktop games. 1024x768 pixel resolution at 24 bits gives a fast enough window refresh rate. 3 Gb disk space is not enough to complete a standard Debian Gnome desktop installation, but I figured out the correct sequence. I installed at first the base Debian 32 bits system. I selected manual disk partitioning and created no swap partion (but a 128 Mb partion is also ok). After that, I apt-get installed the following separate packages: gnome-session, eog, gnome-terminal, gedit, yelp and gdm. To access the graphical desktop without opening the VPS control panel, I use UltraVNC. VNC password is truncated at 8 characters; this seems to be a SolusVM limitation. Qemu keyboard mapping for the VNC session is set to USA international on the host side. I opened a ticket to enable international keyboard in the VNC window, now waiting.
Edit: after less than 15 minutes, ticket was answered and the setup is complete. Time from the end of the countdown on Debian startup screen and complete loading of the Gnome login: 5 sec. Time from the enter key press and complete gnome desktop load: 3 sec. A complete reboot cycle from opened Debian desktop to open desktop again takes less than 40 seconds, including the waiting countown time at the Debian boot screen and the time spent to enter a long password. Actually, I checked again and the time needed to enter the password is about half of the total reboot time. This is fast.
How is the network speed? 100mbit or gigabit?
Thanks pcan
@subin gigabit
@pcan I installed Xfce desktop and is only using about 1gb of the hd, with a swap of 128mb, I still have about 1.7gb of space left on the hard drive..
If anyone is interested, install the base Debian with ssh.. then
aptitude install xorg xfce4 xdm
Although the icon for iceweasel is shown in the desktop it does not actually work until you install it..
aptitude install iceweasel
and then you access it through VNC?
Is there any other better method than VNC?
@subin yes you can connect to your desktop by VNC through solusvm directly which can be kinda laggy but you don't need to install additional packages on your server..
I installed a vncserver on the VPS and connect to it with ultravnc as the client..
Not sure what you mean better method than VNC? an alternative would be freeNX, NoMachine.. never really tried it thought- I think the major difference is you can get audio which you cannot with VNC
My ping time to Prometeus is 55 ms and the VNC session published by Qemu (the solusvm VNC console) is not laggy. I also have an identical setup at Hostigation (220 ms ping time from my location) and the lag is very noticeable. The lag seems related to poor VNC local cursor emulation and excessive latency. I wonder if NX works better; RDP surely works better than VNC with high latency connections.
Xfce is nice but I like Gnome more. The issue on Gnome installation with less than 5 Gb disk space is the bloat included in the standard package. With only individual core packages installed, the disk space required by Gnome is marginally more than Xfce. I also needed the full LibreOffice suite and Chromium; the residual free space on my setup is 390 Mb.
Maybe laggy was not a good term to use.. I was implying that connecting with QEMU vs ultravnc you can really feel a difference and this is on a local machine where ping was practically nil. I just installed NoMachine today and it's definitely faster than VNC, moving a window in VNC you see a little fragmentation while in NX it was smoother more like RDP I guess... The problem with NX is that I can't seem to get private key working so I have to enable password based logins which is not good!!
The VPS is definetly snappy.. but if i recalled the DD test was pretty close to Hostigation's KVM at around 200 MB/s which was just sata drives not SSD.
Overall it's a pretty good VPS, I put in a request yesterday for a Centos 5 image so I can try to install kloxo.. so far support has been really helpful, hopefully by tonight they will have the ISO loaded... Not much to complain about really they are a pretty good company for a budget host!!
And it's up.. less than a day and both 32 and 64 bit version of centos5 was loaded without me having to ask.. Just awesome support!! have not been with them long but so far it's been excellent!!
Hi folks, we have received some request for a 128M kvm plan. Since disk space is proportional to the ram, will a LET plan like this useful ?
CPU: 1 Core
RAM: 128MB
Hard Disk: 2GB
IP addresses: 1
Dedicated internet bandwidth: 256 GB
semi-annual: €10.00 / $ 13.00
Yes, I can think of some uses for a 128 Mb Ram / 2Gb SSD plan.
From http://en.wikipedia.org/wiki/Solid-state_drive : "SSDs do not employ any moving mechanical components..."
So, IMHO, SSD performance will quite constant under high load
I would think so.. or maybe the same since the Hostigation is Raid10 and the SSD is only Raid1, hard to say.. Also not sure how accurate a DD test is for real performance since some VPS I own have excellent specs but pages tend to load slower than a lower performing VPS where pages load instantly..
I would like to try a SSD VPS in this type of configuration:
Samsung SSD Awesomeness
dd sequential test is useful only when it show under 10MB write rate :-)
SSD should give a more stable i/o and applications with database backend should benefit from this...
This offer was just too good to pass. So I got one and done a few test. This is fast. I already own 2 other vps with prometeus, both OVZ and work great, but this perform even better.
disk test is boring. running ioping returns a constant flow of "time: 0.1 ms" so no surprise this is the fastest real world i/o i ever experienced.
IMHO Prometeus is among the top quality vps provider in Europe, with OpenITC XenVZ and PC Smart Group XenSmart.
Short review after 2 more weeks: Still fast after they filled the node, never had a single problem yet, this vps rocks. Thanks Prometeus
