For a quad core processor with 16-32GB RAM and SAS raid 10, would 30 VPS's be a lot?
I have a VPS with 1Gb RAM on a machine as above. I'm running about 40 (relatively low-volume) websites on it. Seems to me that if 30 others were doing anything similar, that would overwhelm a single machine.
Am I just making an uninformed bad assumption? So far, performance on my VPS has been fine.
We have one Cloud Server hardware node that exists only as the backup location for containers and VMs in Cloud Server/PVA (it hosts no virtual servers). Can it also serve as a Backup Server Node?
A related question, in my case, is whether we can configure a Backup Server Node to use a particular drive/mount/directory, as we can with PVA? I couldn't find any info in the docs about any settings at all for the Backup Server Node.
Do VPSs on the same physical server share the same IP?

View 5 Replies View RelatedI currently have 2 VPSs that I'm monitoring and I noticed that on one of them the memory usage is much higher than the other which doesn't make sense to me. I tracked the high memory usage to the Apache processes.
Here's the overview of the VPSs:
LiquidWeb VPS- 512MB RAM, 10 Sites with minimal usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 1.2 /usr/local/apache/bin/httpd -k start -DSSL
Virpus VPS- 384MB RAM, 61 sites with moderate usage.
Average httpd process (Owner Priority Cpu% Mem% Command):
nobody 0 0.0 0.3 /usr/local/apache/bin/httpd -k start -DSSL
Both Apache configurations are identical, the only difference besides the hardware is that LiquidWeb runs CentOS4.7 and Virpus runs CentOS5.2, any ideas? It's not to big of a deal since I'm not near my limit for either of them but I was just curious.
what's going inside my provider Powervps/Defender hosting, they are offering now 25% OFF of new customers + triply bandwidth.
Curent customers are not allowod to get this offer, until they order a new VPS and cancel the older.
I'm asking, because i feel, it's samething, why they don't go upgarading the account throughly with keeping IPs and data..? why do old customers need to cancel the old VPS then they go get a new VPS..?
are Old VPSs powerfully then the newest..? any informations...?
I'm searching for how to create a VPSs From dedicated servers and sell it ..
the dedicated server will be :
4 processors 3.0
8 GB ram
1024 GB H.D.D. Sata II
1 GB Uplink
In order to increase the reliability of a audio streaming service I am thinking to take the action I describe below.
1. Buy two Windows VPSs with WMS installed.
2. Register a domain name (i.e audiostream.com) with 4 nameservers: ns1.ip1_vps1, ns2.ip2_vps1, ns3.ip1_vps2, ns4.ip2_vps2.
3. Create all publishing points (streams) on both servers.
Normaly VPS1 should serve all clients. In case VPS1 goes down, VPS2 should jump in and serve all clients-connections. As soon as VPS1 becomes available (ns1 & ns2 start responding again), VPS1 starts serving all new connections.
Load balancing or any other kind of advanced load, traffic, etc management is not important.
Then we have the following cases:
1. VPS1 is down , which means that VPS2 should take charge.
2. VPS1 is up (ns, http, ftp services), but WMS1 is down (crashed). Means that the playlist (asx) file should be built so that it also includes the IP, port & publishing points of VPS2. This should be done because ns1 & ns2 will answer without any problem, but WMS1 will be crashed and won't serve any media connections, thus ASX will look for the next available stream in the playlist.
Do you think that the above is possible. Is this gonna work?
if i can create 2 VPS with completely different OS such as CentOS5 and Windows 2003 Std.
The main server will be running CentOS with HyperVM.
Last month I order 2 Xen VPSs from Xenvz.co.uk and use them for VPN proxy.
But a few days ago, xenvz stopped one vps and state "This is because it is spreading the Conficker virus.". I'm a little surprise because there's only 10+ users on this vps. Most of them use VPN for visting Youtube or P2P download or gaming. And Conficker virus can only run on Windows, but all my vps is running on Debian.
Maybe someone had download something that contain Conficker virus?
Anyway, I had to move a few users to another vps yesterday.
But xenvz stop my another vps today for the same reason!
I really do not know whether or not one of my user is spreading or other reason, but as I know, Conficker virus had affected thousands of hosts in the past. If someone download or being affect by conficker for any reason, provider then stop their host, I'm afraid thousands of sites would down.
Most VPS offerings have "burstable" memory allocations. I get how you can do this with most things -- letting a VPS access more CPU cycles can be done pretty easily, and a 10 Mbps line burstable to 100 Mbps makes sense.
But how does the guest OS handle all of a sudden having more memory? Since a lot of VPS guests run without modification, how does this work? Does the typical Linux system support dynamic changes in RAM? I can only imagine that dealing with "un-bursting" is even more complex: suppose I have 128MB, burst to 512, but then the host node tries to reclaim some of it. Is the system smart enough to seamlessly swap out to disk when RAM "disappears?" I'd fully expect a kernel panic when the system's RAM shrinks in size, particularly when the RAM was in use.
I'm curious about exactly how all of this is managed. Given that 95% of VPS hosts give a burstable range of RAM, what exactly manages this? Is the virtualization platform handling this and somehow "tricking" the kernel, or is the guest system able to deal with changing RAM allocations? And, if the latter, is this a standard feature of the Linux kernel, or are guest OS mods still necessary to deal with burstable RAM?
i'm a vps provider and i'm using this server for vps host
Code:
Dual CPU Xeon 5420, 24GB Ram, 1TB HDD
24GB of Ram
and now i see the used ram is un normal

the free ram us 199 of 24GB!
every time when i reboot the server the used ram back normal but after per hours the issues back again
i have contacted the DC and they say that there is no problem with there hardware
the number of vpses in that node is 7 and all the vps have a limit ram.
I want to build a VPS Node using Quad Socket Tyan Motherboards and AMD Opteron 2376 Shanghai 2.3 GHz Processor (Quad Core).
I am in doubt since I notice that some providers (at least two rather big provider which I have account) are using Dual Core AMD Opteron 2212.
Is there any specific reason why those providers is not using 2376 AMD Processors? .. is it because the Dual Core AMD Opteron 2212 supports Virtualization Technology, while the 2376 is not?
I will use Xen Hypervisor, usually I use Intel 54xx Processors but looking for *cheaper* solution , so I am really new in AMD Base Server.
I build raid10 for VPS nodes. Now, I will use SAN, so all VPS will be created in SAN. With the host server, I assume that I don't need fast disk array, because all the disk requests have been processed in SAN already?
View 4 Replies View RelatedWell the age old question for virtual servers, would you rather a host put all his eggs into one basket "monster node" or several smaller ones. From a provider standpoint one server is easier to manage than several, although if that one goes down, all your customers do with it. Lower costs for the provider, s/he can then pass the savings along.

i have a very high load in my node every time i monitor the load i see load average: 8.19 and some times it's go up to 60 - 80
i'm using this server
Intel Core2Quad Q9650
Ram 8GB
Bandwidth: 10000gb
Hypervm Control Panel
and there is only 6 vpses ....
i'm using hypervm/openvz
and i have the main package of ips which i have received from datacenter
i orderd other package ips (13) ips
i have add them to ip pools in hypervm and it didn't working
Note : netmask are different for the first ips and the second ips
when i create vps i can't login and when i ping ip it didn't ping ( requested timed out )
i have one server from softlayer and the other from limestonenetworks
when i order additonal ips from softlayer it works proberly .. now when i orderd those ips from limestonenetworks ; i think it must be modified manually
i have node 16 cpu AMD 64 gb ram HDD sas 15 with raid 10 /hypervm + openvz i host 10 vps
my problem when any vps load go over 2 the Node load go to 30 - 40 some time 100 i set CPU UNITS , Number Of CPUS and Cpu Usage for every vps but the load in node is go up
how i can set limit in vps and prevent from effect on load Node?
GeekLayer is looking in to expanding in to the UK - We want to offer VPSs in the UK, but to be honest, I have no idea who people consider the SoftLayer of the UK hosting industry - Who has the best rep around WHT with reasonable(ish) pricing for something like a core2quad with 8gb ram and 2tb+ bandwidth?
View 4 Replies View RelatedI figure while I am twiddling my thumbs here waiting for my host to tell me what the heck happened for the second time in two or three months why they have to do an entire VPS hard restart, which of course causes another hour of fck delays, that I'd ask some of the more skilled and experience folks here, how?
Just before it happened, as I was watching, the load shotup over 1, 2, 4, 20, 30 boom. (I opened a ticket at 4)
Shouldn't virtuozzo always guarantee a certain amount of cpu and bandwidth to the node root? Why do they have to hard reboot and not access it directly and stop the badly behaving vps? Better yet, why isn't the badly behaving vps stopped automatically by virtuozzo?
(oh and am I an idiot for putting up with over two hours of downtime?)
I'm reseller vps, and now i decided to run own node, and sell vps, i choosed VDSMANAGER control panel, because virtuzzo is expensive.
Please help me to choose best options to run best and quality node,
VDSManager or VEportal ? (good optios&security&support&...)
XEN or OPENVZ ? (uutil now OPENVZ best for run static and dynamic site, but on xen can be run vpn & shoutcast & windows & linux & ...)
RAM GB ?
CPU ?
Hard ?
can i use load balancing for vps node ?
how many vps can be run on this node ?
Ex:
VDSmanager
XEN
Core2Quad Q9300
8 GB RAM
500 GB HDD
Let's make this straight,
I have this vps,which is pending cancellation in a few days.
Hardware Node = EL 5 x86_64,
Vz = Xen
I asked my provider for 32 bit centos, I even rebuilt it, but my "uname --all" still
Quote:
Linux xxx.xxx.com 2.6.18-128.1.10.el5xen #1 SMP Thu May 7 11:07:18 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
so I opened a ticket asking about the vps arch.
The provider have told me that to run a vps 32 bit guest, what you have to do is (?)
+++++++++++++++++++++++++
yum clean all
echo i686-redhat-linux > /etc/rpm/platform
+++++++++++++++++++++++++
so yum will exclude any x86_64 packages.
The provider has told me also that my "uname" display x86_64 because the hardware node is 64 bit. Is this true ?
I'm no linux or vps guru, but that's doesnt feel right at all.
This has cause me some issues especially with kernel-headers and some program failed to compile.
So, is it possible to run a 32 bit OS as xen guest inside 64 bit node?
I want to know if there is a set of tools or a linux distro that I can use to create several Virtual Machines and make them use up all their allocated Memory/CPU to the max to see how much the VPS Node will hold.
I do this on Windows easily as I overclock my PC at home. But in linux, no idea. I need something that will do iterations like Prime95 or SuperPI.
I had 3 IP pools in HyperVM node. I removed (deleted) 2 pools completely because I had an error trying to create a VPS, told me the IP was being used by someone else. So I deleted the pools completely and I see they still ping. I did a tracert and the IPs come to my server so i know nobody else is using them or that they were assigned to somone else. I rebooted the server and while it was in the process I tried to ping the ips and they didn't respond. When node came up, the ips started pinging again. How can I manually remove the IPs so that my server doesn't respond to the pings and I can add them to the pool and use them correctly.

My VPS wen't down around 9am (Pacific) this morning, send a ticket in and have not heard anything back. Trying to start it from HyperVM results in:
Alert: no_kernel_support_for_openvz_check_if_right_kernel
Not sure if this is an issue on my side or on the entire node, haven't seen any threads regarding it yet so thought I'd make one. It's been about 4 hours now and my ticket hasen't even been updated yet. Just wondering whats going on...
Ryans usually been on top of everything whenever something happened so I'm going to wait a few more hours before calling them.
I mistakenly ran ELS script [url]inside the NODE in root mode instead of inside the vps container I was intending to run the script in, and everything basically stopped working - even after a hard reboot.
No vps's load, no sites work. The vzagent is not pinging. Cannot connect via VZMC as a result.

Most likely your service Virtual Private Server is down or you have entered invalid host address.
I stopped the ELS script at the mytop install yes/no step. I selected yes for all previous install options EXCLUDING apf and bfd. I did a yes on sysctl.conf hardening, disable register globals, chmod dangerous file folder (which probably caused the problem).
i just buy a dedicated server for vps reselling.
this is my hardware spec :
Intel XEON E5420
4GB Ecc memory
2x250 GB RAID 1
hypervm/xen
the question is:
how to setting ip pool
how to setup a "resource plan"
how to add a guest vps
I'm currently considering to enter the VPS market
I have recently acquired a nice box (2x Dual Core Opteron 275 2.2 GHz, 16 GB RAM, 16x500 GB SATA @ RAID5/6) but I'm unsure if it isn't smarter to buy smaller machines (like X2 5600+, 4 GB RAM, 2x400 GB HDD) and put like 15-20 customers on it.
Yes, I know that the hard drives are more than oversized for VPS hosting
The Opteron server will have a very, very nice I/O performance so that customers are going to have a good feeling while working on it. To refinance the costs it would of course be neccessary to put not less than 125 VPS on one box, so I can imagine that there'll be a bottle neck somewhere (CPU power I'd guess?).
What is your opinion? Big boxes with high performance and loads of customers, or small boxes with not-so-many VPS?
I have been with SolarVPS for some months now, and I'm pretty happy with their services. But some months ago I have problems with very high CPU load on their server, every day for a week or so. Since then I have had little problems, before the last two days. Now they are back to the same problem as last time, almost 100% CPU load on their server, causing my sites to work VERY slow, and I’m getting timeouts on my MySQL database.
When sending tickets, they kill the process, but it’s only mather of time before the CPU skyrockets again. Yesterday they told me that it was a abusing client, and they was taking care of it. But today I got the same problem.
Are they hiding the fact that they have oversold the node I’m on? (the UK node), or do I only have bad luck? And how much can I take before I start looking for a new host? I think their service and support is very good, but not when I got problems with high CPU load. They reply fast on ticket, but I cannot monitor my server 24/7 to see if the CPU load is high.
What would you have done if it’s was you that had the same problem. Do I have to accept the fact that I only pay around $55/mo for a 384MB/25GB/150GB BW and 4 IP’s (with Windows 2003 and Plesk 30 domains) and cannot demand a VPS server that runs without problems?
Anyway, it’s my experience with SolarVPS after 3 months (and three days).
Who are the most reliable Dedicated/Node Providers? I mean there are the cheap ones like Wholesale Internet and Joe's DC but have they proven to be reliable as well?
