Virtual Iron Cluster
Mar 23, 2007Can anyone recommend a dedicated server provider that will allow us to setup a virtual iron cluster.

View 1 RepliesBasically I need to virtualize a single new dell server. One virtual server needs to run windows 2003 server standard and Microsoft SQL 2005. The other virtual server will run CentOS Linux with a perl and PostgreSQL application.
The dell server is going to have two quad core xeon processors (8 cores total), 8gigs of ram, and two 15,000rpm SAS drives.
I came across Virutal Iron which is free for the single server instance and seems like it will do the job well. Has anybody used it? What is performance like? Seems to run a Java backend so wondering about the performance there.
Any other recommendations? I looked at VMware but the cost is so high, and probably more then I need, since I only need to virtualize a single server.
A company i am working with is looking to install a VMWare setup comprising of something like this :
6x Dual Proc Quad Core Nodes with 16GB RAM
2x Clustered iSCSN SAN Nodes
I am intending on purchasing the full suite including DRS/HA/VMotion.
Now this is all well and good but the software pricing is absolutely horrendous! So my question to you chaps is :
Is anyone using the latest Virtual Iron or Xen Enterprise in a high end environment?
Obviously VMWare is the market leader, the big boys are using it and its something you can bank on. (literally! HSBC use it ALOT!)
Is it even worth looking at VI/Xen for something like this? The cost would be like a quarter of the total cost of a VMWare license.
Could nameservers be setup in cpanel/WHM between multiple VPS so they could be used across them all or would that require dedicated servers?

A brief example. There was some confusion on my billing, probably mine moreso than theirs. Here is part of the message I got from support.
"First of all, we would never shutdown your VPS without letting you know way ahead of time so don’t worry about that."
I've had my hosting account with Iron Mountain fairly happily for around a year or so now ... it seems though that recently things are headed downhill.
Support requests get answered - eventually. I had sites down and very slow yet again today (lately seems like a common occurrence), and a ticket submitted about six hours ago now has as of yet gone unacknowledged.
I've gotten used to endless FTP timeouts and generally spotty speeds, but it's definitely gotten worse... to the point where I might have to go shop for a new provider.
Having some clients on Iron Mountain hosting who I depend on to make my living, this is just a little to risky!
Caveat: I do have a shared plan, and it's definitely quite inexpensive. So, this could just be a get-what-you-pay-for scenario. Regardless though, in my more recent experience, they are helpful and generally nice to deal with. But neither service speed nor hosting service quality are particularly great.
In my whole entire lifetime I thought that I would never do a 1 year review on a host, ever. Each time I signed up with a host; something came up - whether it was needing more diskspace or bandwidth, excessive server downtime, getting "you did x thing and you must leave" notices, or just wanting something closer to home - that is, until I found Brandon and crew at iMountain.com.
The stay from 8/5/2007 to 8/5/2008 has been nothing but pleasurable and enjoyable. While there have been some bumps along the way (UPS explosions, ISP !@#$ ups, etc.); this has been by far the best host that I have ever used.
Their servers are very fast and reliable. With 8 core AMD Opteron CPU's powering their web servers to a whopping 16 core AMD Opteron CPU setup for the mySQL server cluster; you never have to worry about server lag. And if by chance the server should bog down, just shoot em an email and it's always resolved within minutes.
Need a custom backup cronjob? They do those. Just be sure you know how to use Crapsphere ... cough, erm I mean Hsphere, as that is the only control panel that they use on their shared hosting servers. You can get cPanel and other control panels on dedicated servers from iMountain, however.
The good thing about iMountain's clustered setup is that if one server goes down, it won't affect your entire site. So if the email server crashes; your web and mySQL will still be up. So on and so forth.
Just load up one of my main sites at [url]to see how fast iMountain.com is. I think you will be very impressed.
Brand new to posting on this forum, but been browsing for a while. Also brand new to VPS, but i recently decided to take my first plunge into the VPS world. I've been using Iron Mountain VPS for about 3 weeks now, and since there seems to be very little talk about their services on this forum, I thought it would be useful to post my opinions, and maybe get the opinions of some others about this provider.
My Background:
I began my search for web hosting because I had been hosting my own email server at home, but began to have several issues keeping the server up and running (power outages, network outages, power supply failures, etc...). My wife was complaining about her email being down, so I began looking for a more reliable solution I'm also a software developer, so I also had some interest in running some "hobby" type j2EE programs, so I began to look at VPS solutions. Since I am pretty technically inclined, I was just looking for a low cost unmanaged VPS solution with at least reasonable reliability that was powerful enough to run j2ee applications, host email, and run a couple other services like hosting my digital photos and setting up a versioning control repository (svn). I actually took the time to make a speadsheet to compare over 10 VPS providers, and eventually found Iron Mountain to be the best solution for me.
Setup:
Their sales department was VERY quick to answer my questions, and very accomodating to my requests. I purchased their Pearl package online, and once the transaction was complete, I recieved an email that I could already log into my control panel. Here is the timline that things happened:
11:35am - Purchase transaction complete
11:36am - Recieve email on my billing info, and how to get into my VPS control panel.
11:48am - Recieved email that my VPS has been initialized, and I can no SSH to my instance
12:22pm - Recieve email that they have already setup a MySQL database for me (on their servers), and it is ready to use (without me even asking mind you).
4:31pm - I send an email (not even a support ticket) saying that I actaully prefer PostgresSQL
4:40pm - Recieve email that they will setup a Postgres instance for me
5:34pm - My PostgresSQL instance is up and ready to go (on their servers!)
So in summary, that is 13 minutes from purchase to having my instance up and running. 34 minutes additional to have a database ready for me to use (without me even asking for one). And another hour of time it took them to get a Postgres instance up for me... Not bad
Perfromance/Reliability:
Let me preface this by saying that I am a father of 2 with a full-time job, so I really don't have time to run benchmarks and such. Also, my VPS is more of a personal site, so I don't have to worry about reliability as much as say a reseller or ecommerce customer. So I'm only basing these comments on preception and my knowledge of the technology Iron Mountain uses. In genereal, I have experienced NO downtime, and performance seems VERY quick. My J2EE application almost seems to run faster off these servers than it does on my localhost development environment... which is good enough for me.
Now let me rant about why I am very comfortable with their ability to continue to have great perfromance and reliability. One key here is that this is clustered web hosting! This means they have (for example) 30 servers working together like 1 giant computer. This giant computer runs all of their customer's VPS instances. If one server were to fail, nobody is losing service, it just means that there are now only 29 servers making up this one giant computer until they can get #30 back up and running. This not only protects us customers against one possible cause of downtime, but it also allows Iron Mountain to do server maintanence and upgrades without interupting any of their customer's service. My employeer has a similar setup in their datacenter, so I am semi-knowledgable on the benefits of a cluster. Now their service could still go down because of things like network issues (which is often out of the control of the VPS provider), but at least it removes risk at one point of failure. If you need anything more reliable than this, you should consider other alternatives such as having a mirrored service with another VPS provider on a completely different network.
Another HUGE selling point for me is that they host my databases, email, and spam filters (and DNS if you need to use it) on THIER servers! All three of these can potentially hog system resources (disk space, memmory, and bandwidth), so to not have them taxing my personal instance is HUGE. This also spares me from having to configure and maintain these services on my own. Oh, and to top it off, the perfomance of these services are VERY fast. However, the flexibiblity is there if you decide you want to host your own database and email on your own servers (obviously).
Support:
As I mentioned earlier, I only really needed an unmanaged provider, and I haven't experienced any issues to this point, so my opinion on their support is limited. However, I have sent about 5-7 emails their way, and have received a response from them within 10 minutes every time! This gives me quite a bit of comfort should a real issue arise.
The funny part of all this is that I can not tell whether Iron Mountain's plans are managed or unmanaged. I guess they are at least semi-managed, as they have setup a database for me without any questions. I guess my question is whether they are fully managed (ie will do backups and install custom apps for you) or not... Maybe an Iron Mountain rep can chime in here.
Summary:
VERY smooth sailing so far. I have email, databases, subversion, apache, tomcat and more running, and still have plenty of resources left over for more. Sales/Support has been VERY friendly, and I have no concerns their. For what I need out of a VPS, who could ask for more. Their prices are also very reasonable, and their new Quartz plan is an amazing deal for a hobbyist like myself. Not really much to critisize at this point, but I will keep this forum up to date if anything arises.
it would appear that Iron Mountain ( www.ironmountain.com ) has filed a trademark infringement suit against InterMountain Mortgage also known as Iron Mountain Hosting ( www.imountain.com ) regarding the use of "Iron Mountain" and various colors and service marks.
I don't think this will come as a surprise to many people given how similar these two names are, along with the fact that Iron Mountain have been involved in IT well before InterMountain Mortgage decided to take the plunge into hosting.
It's going to be an interesting trial by jury to say the least...

Anyone had any experience with setting up an ftp cluster? We have tried to search Google and haven't been successful in such a solution so I came here to ask if anyone else has ever thought about doing it. Or done it and how did you do it? I'm looking in to it for windows. 99% of my servers are windows.
View 3 Replies View RelatedI see more and more hosts popping up (and older hosts switching to) offering what they call clustered load balanced plans. These plans are mostly on the low end price wise (sub $10/month), and the marketing speak tells of zero downtime, intelligent clustered, load balanced, failover, will wash your clothes approaches to keeping websites up 110% of the time.
I guess what I fail to grasp is are these plans really, truly load balanced clustered approaches, or is it more of a case of we have 1 DNS server, 1 mail server, 1 web server, 1 mysql server, and a backup server that in an emergency has rsyncs each hour to "failover" to and screw up your dynamic data?
If the webservers are load balanced, what about accounts that use SQLite db's, or berkeley db's, are these maintained 100% in synch, and if so, how? If one server goes down, and the other picks up the slack, won't the db's be out of synch and data contention will occur? Are sessions including SSL truly handled correctly?
Same for MySQL. Is this true two way replication with fault tolerant switchovers between master and slave to preclude data loss and corruption on hot switch overs when a server fails?
I guess I just see everyone slapping a "clustered" label on things, and speaking of load balancers, etc... all for the cup of coffee a month. But I am highly suspect if these plans are truly load balanced, or is it a band-aid approach to load balancing?
Just the ranting of a an older hosting owner who's just not sure what many companies are truly offering when they speak of clustered, load balanced, more uptime than Viagra type of solutions...
We have been running two dedicated servers for a number of years now and we use Cpanel and DirectAdmin for the control panels. Today we had a big problem with our first server which effectively made the 150 sites on it out of action and it exposed a potential issue to us that if the server died that we'd have a big task restoring all the sites from the backup drive. I've heard that some hosting companies strip data across more than one machine and I presume this is a cluster, and I was wondering if this is the best method and what the most cost effective route would be to do it?

Most of the cluster solutions out there want you to recompile a custom kernel which cannot be done on a vps. The virtual machines are on different hardware nodes and I don't have access to those since I am renting the VPSes from another company.

View 3 Replies View RelatedOn setting up a pair of CPanel DNS only servers, I decided to use 2 Virtual Servers from 2 seperate companies - one Xen and the other was Openvz. Reason behind it was in case something happens to the company or the virtualization technology implemented, I'm not screwed.
Guess what! Next day my Openvz node (I will not name the provider) went south and I'm on one leg right now. I'm kinda pleased with myself for having this laid out from the beginning and DNS is still working fine.
Now I'm thinking of having different OS - one linux and the other freebsd. Am I paranoid and over-the-top?
we are planing to build a 5 system mysql cluster for our website. i have few questions regarding this. As per our provider, we need mod_ndb for apache to connect database cluster. (SQL API). we have 5 system apache cluster.
Mod_ndb configuration, we need to add all table structure in http configuration. Is there any other way to connect database? or any other way to configure mod_ndb without adding table structure inside http configuration.
any other better way to connect database
All my sites that depend on MySQL at iMountain have been down all day. I was in the process of converting some of them to Joomla/Drupal but I'm having second thoughts now.
My question is - shouldn't "clustering" prevent this sort of thing happening? I thought it implied some level of redundancy.
I try to keep on the up and up about hosting and constantly looking for a new host to provide better services, but I saw an article in TheWHIR that got me to wonder if people are making stuff up or is it just "marketing" or real?
Ok, so the article:

I hope adding a link to the article is ok?
First of all I have NEVER heard of cPanel ever offering clustered technology. Can anyone confirm or deny that this is real? I have really only used HSphere which I know has some cluster abilities and even those hosts don't advertise "clustered" services.
Then I see other so called cPanel wannabe clustered services which they call cPanel clustered failover or something like that which to me is ummm..more fault tolerant hosting than actual cluster hosting.
Basically, am I just not understanding the meaning of "cluster"?
I think cluster has to do with the proper allocation of reasources spread across the network of defined processes, though, I have been wrong in the past...
i have a site which involves heavy cpu use but its in a small private network with 3 other boxes which are pretty much idle, so im wondering is their a way to use the idle cpu time /ram possibly on my main server via the network ?
View 5 Replies View RelatedI have a total DB in size of 800MB... Recently I had to make a few configurations in the management tool and had to do an intialize restart... Not sure what's taking so long, but it's been nearly 8 hours and I have not seen any of my tables that used to be there.
When I do du -sh /var/lib/mysql-cluster, it shows that I have 800M /var/lib/mysql-cluster...
I just need a bit of feedback, I currently have a forum, getting around 20-35k uniques per day.
I am currently on a Intel C2D, 4gb Ram, paying around $185/month.
Would setting up a cluster help me reduce the costs or load?
Cluster = 1 server for httpd, 1 server for mysql, 1 server for images?
I would like to understand what is the difference between VPS and a VDS. I understand they sound the same, however from a cost stand point VPS is way cheaper than VDS, and I am not very sure of the reason.

Anyone have issues where after setting up cpanel dns cluster via whm, cpanel fails often on the clustered boxes?

and I'm curious about the space and bandwidth of this service
I'm planning to upgrade my servers to a more "enterprise-class" installation and would like to hear your advice for good managed hosting providers for this.
Currently I use RackSpace which are great but pricey (leased servers); in the past we had a colocation with another provider: it was good cost-wise and generally proffesional but alas the provider's infrastructure was not sufficiently resilient to natural disasters and unlikely but occurring infrastructure accidents.
My feeling is to stay with a more managed service rather than try to colocate again: we need someone making sure the hardware stays around 24/7 and makes sure to have the appropriate spare parts and expertise in the hardware they sell us. We can handle the software parts.
I'll probably stay with RackSpace because they can and have already built stuff like the below. But maybe there's another provider out there which fullfills similar needs for customers.
My needs are:
1.5 TB of shared storage (i.e. SAN or NAS; must be reasonably fast (maybe 10MB/s sustained) and 99.99% up); add .5TB per year
4 application servers in various configuration (8-16G of RAM, quad or dual-quad Xeons)
2 database servers (With fast drives in RAID-10 but not much disk; most of our data is not in an SQL server)
Some appropriate load balancing appliance (with at least 99.99% reliability)
Red Hat Enterprise Linux 5
Redundancy to a point (i.e. redundant mechnical parts, hot-swap drives)
Usual stuff: managed backup, private network, hardware monitoring with fast hardware exchange
No Linux system administration beyond a sane installation needed
99.99% uptime on the network and infrastructure (i.e. if an UPS blows up or a router goes down this should not affect me; redundant connections to multiple network providers etc. etc). RackSpace has a 100% network uptime guarantee and in the many years we've been with them in one form of another I haven't been disappointed in their competency on that front.
This would be in some US datacenter. Does someone have experience with such a scale installations with other providers (or RackSpace too) ?
(I wrote "SAN or NAS" because I'm not really yet sure if some NFS server or maybe shared storage via SAN and something like RedHat's GFS will be best for my needs; it would be nice if the provider was capable of advicing on things like that).
I have started to move my websites over to my UK Colocation But would like a little guidence on what the best solution would be.
I would like to build up a Server Cluster that will handle all of my sites really and also have redundancy, so If 1 server goes down the other Web/SQL/Whatever server will be used instead.
I have websites ranging from large forums to streaming & download websites.
Should I got for a setup for example:
X Web Servers + X Database Servers
Connected to X Storage (see link below)
Connecting the Web Servers in something like a a round robin config or use a Load Balancer / Other
OR Should I setup multiple:
Web Server + Database Server + Media Server
OR another config?

We've come to a crossroad with our site and not sure where to take it from here. It would seem like a cluster option would be the best bet, but wanted to ask the professionals first to see if there were any other way to solve it.
The problem is (as usual) too high load making the servers slow. Actually, only the apache server. We recently seperated mySQL and apache on two servers to help out with the load. The mySQL server load is around 0.25-0.5 throughout the day, but the apache server load is almost always at 6.xx-10.xx.
Both servers has the following stats:
CPU: Intel Core2Quad Q6600-S3 (Quad Core @ 2.4GHz)
RAM: 8GB DDR2
HDD: 750gb SATA2
Average Daily Stats:
Uniques: 60 000
Pages: 1 300 000
Hits: 14 700 000
BW: 95 GB
Concurrent users on vBulletin forums 250-700.
* Shouldn't an apache server with these stats be capable to handle the current visits?
* Could this perhaps be solved if we swapped the sata drive with a scsi/sas?
If we're moving to a cluster solution, we'd be looking at minimum 5 servers.
2x Load balancing servers
1x SQL server
2x Apache servers
Preferably we should have 2 SQL servers for redudancy, but for a site that is hobby based, it would be insane to pay around $1245-1490 a month just to keep it up.
Key stats from httpd.conf
Code:

View 10 Replies View RelatedThis is clearly the next logical step in hosting. Consider what RAID1 did for hard drive availability. Worried about your disk failing? No problem - throw in a duplicate. From a user/admin perspective the mirrored disks appear as one, highly reliable disk. Every modern OS supports this, even cheap motherboards support it, with a minimal amount of configuration.
The perfect high availability cluster should be completely transparent. Think about it... What if clustered hardware allowed you to manage a single instance of your chosen server OS with no worries about hardware/network/power failure?
The closest you can get to this finding a host that will give you a dual power supply server connected to different power feeds, dual network cards connected to different switches, and hot-swappable mirrored hard drives. This solution still doesn't give you any protection from CPU, memory, or motherboard failure.
I want a solution that is as simple to configure and manage as simple RAID1 mirroring.
