I am configuring an environment where several servers are going to boot from iSCSI.
The chassis will not have any local storage.
I am looking for cheap 1U chassis where I can plug in a decent PSU and a Super Micro X8STi-F with an Intel Core i7 proc.
In your environment, have you ever used diskless machines (e.g. booted with BOOTP/DHCP/TFTP) for any reason? Where in your environment are you making use of them (e.g. what types of servers - web, application, database, DNS, etc...), and how has it turned out for you?
Has it actually yielded any of the promised benefits that the literature on them says, or was it a pain to set up and maintain?
Any interesting use cases on what you use them for and, as importantly, what are your criteria for determining whether a particular type of server should be diskless or not?
As this forum is filled with people with lots of experience running hosting businesses or their own web applications and therefore have managed thousands of machines between yourselves, I figured this is an appropriate and interesting question to ask. I'm hoping to get insights from here that I can't get from reading any old web article.
where to buy server chassis in Europe?
View 7 Replies View RelatedCan anyone recommend a good 1U server chassis that is $100 or under?
Preferrably one already with a good/reliable power supply in it. Just something that will handle PentiumD or Athlon AM2 stuff & 2 hard drives.
I've bought a chassis "SuperChassis 512L-260" from Supermicro. Now, I want to install an Intel Mainboard (Intel S3000AHV). It's only a testing server.
Which I/O shield do I need and where I can get it (am I able to change it?)?
Perhaps, I have to use a Supermicro mainboard?
We are using the SC512L-260B chassis for our lower end machines, what is a good recommendation for say Dual Opteron or Dual Woodcrest servers?
Looking 1U that will handle 2 drives, but would also like a recommendation for going with 4 drives (would this require 2U?). Hot swap not necessary.
what type of motherboard can fit into a RM215/217 server? We purchased some of these from a Dutch supplier 2 years ago, and they were delivered with Tyan AMD motherboards with S939 CPU's.
These are used for file storage, and are running 3ware 9550-sx controllers. Tasks are only rsyncing, gzipping, and rotating backups. Problem is that this is now happening fast enough with the single Opteron 2Ghz CPU they are carrying.
I want to do something like this;
* Dual Xeon Nocona, 2.8Ghz etc as we have _many_ of these CPU's already
* Dual Opteron 250-252 etc
* If as fast as the Dual Nocona, maybe a Core2 Duo, although not sure what is available w/PCI-X
So, if anyone knows, or can give any ideas, OR has any Nocona-capable motherboards for sale in Amsterdam for sale, please let me know,
BTW I have already tried doing the x2 chip upgrade on one of these, and was not impressed. The motherboard which is in these machines now IIRC is a S8965 Tyan - which has 32 bit PCI slots. I believe one of the problems here is the controller needs a 64 bit PCI slot to sit on, as it's saturating the 32 bit PCI bus.
Disk config is 8 x 750G / 9550-sx - again all I need is
* gzip / tar / move the files around & delete them
* figure 3-4TB of data on each of these boxes

I have bought an Intel SR2500LX server chassis with a S5000PAL mainboard running Centos. This system has an active backplane with a LSI MegaRaid chipset.
I'd like to be notified in the case of a drive failure but I'm totally stumped on how to get any monitoring working.
The only raid managment utility Intel supplies is a Java based monstrosity, which needs X-Windows to run and needs to be run continuously in order for the email notification to work.
Web based management can only be used from the same subnet as the server, so that's not very useful either.
I've contacted Intel support which gave me the advice to reboot the server and use the Bios utility if I want to check the Raid arrays consistency . Needless to say I'm very dissapointed, this server has every redundancy feature you can think of but it seems impossible to monitor the Raid under Linux.
Does anybody have experience with the Chassis and Raid monitoring under Linux?
Has anyone been using a 1333 FSB Core 2 Duo board in the SC512L that will fit without modification? Looking for something for mass use, I know some of the server boards will fit fine, wondering about some of the ASUS or Foxconn boards.
View 1 Replies View RelatedI have a lot of questions here so if you can't answer them all I understand. even pointing me somewhere where I could get the answers would be appreciated; hardware sites focusing on server hardware, forums focusing on such, etc.
we plan to have three different types of servers:
- db server (self explanatory. mysql. for forums, mysql driven sites.)
- file server (lots of files around ~2-10MB, consistant 70mbps right now, but we want more room for upgrades. needs a LOT of storage room.)
- web server (lots of php files, but also static things like plain html, images, etc. also includes all misc services for the setup-- dns, etc.)
could I be given a rundown for which hardware each of the three should have? I don't need specifics, even just knowing that more ram is important here while cpu doesn't matter as much, or that the fastest disks available are a must, etc would all be valuable info for me. despite that, I certainly wouldn't mind specific hypothetical hardware configs.
for the database server I'm assuming the more ram the better. not entirely sure about the cpu? also not positive on disks...
for the fileserver, how much ram would be practical or useful? disk io will be an issue I'm because plenty of people will be pulling files at once so the disk needs to read from multiple places. scsi (and even raptors) are not an option as we need 750GB+ of space on a reasonable budget. more ram will take some load of of the disks, but how much is neccessary / reasonable?
for the web server I'm assuming cpu first, then ram, but it'll likely need less ram than the db server?
I'm more lost on the disks than anything. scsi on the fileserver is not an option under any circumstances due to $/GB. for the db & web server I'm willing to pay for scsi if the performance increase really does warrant the extra money, but I'd like to be convinced before shelling it out. if you have benchmarks geared at server hardware when it comes to disks I'd really appreciate it.
also, what's the best way to network these together when colocated? each one with a dual gigabit ethernet port and then the communications go to and from the router?
We send mail to another servers but we cant recieve mails another servers. We can't recieve with webmail and outlook.
I look logs but there is no error and our ip is not in blacklist.

I was wondering if it is possible to cluster 2 web servers and 2 mysql servers with only one server working as load balancer.
I am planning to use LVS (ldirectord and heartbeat).
Let's say I have 3 IPs allocated to the load balancing server.
111.222.111.222 (Main IP)
111.222.111.223 (Web Load Balancing IP)
111.222.111.224 (MySQL Load Balancing IP)
If a connection is made to .223 it would pass the request to one of the web nodes.
If a connection is made to .224 it would pass the request to one of the MySQL nodes.
Is it possible to do this?
If not, can I run, for example, nginx on 223 IP address to provide forward proxy? (Then it would not be able to HA but the main point is to load balance so)
Also, what would be the best way to keep the data same on both web servers? This is a web cluster for a very high traffic forum with a lot of uploads every hour so it has to do real time synchronization. I heard that DRDB is only one way and not two way so I'm not going to be able to use this.
I am just colocating servers and managing them myself, and renting services off of them. In the future I would like to start offering dedicated servers as well. I am wondering if many companies do this, or if its more of a general practice to just setup as a reseller? The worst part that comes to mind is thinking of how to do billing for the bandwidth per month. With my setup I would only be offering flat bandwidth packages (like 2TB a month) but even so, I cant think of anyway to automate it so WHMCS knows if they went over, if so, how much, etc.

I have recently purchased new hosting with a new supplier which uses a different kind of control panel - cpanel. So before I transfer our organisations website across I want to spend some time playing.
We purchased our domains with 123 reg and the host we have been using for a while is namesco our new hosting package is with neither of these suppliers.
Before I transfer our primary domain to the new host I'm doing a dummy run with one of our other domains and that's where i've come up with this name servers question.
The new host gave me the name of their 2 name servers.
But when I went to my control panel at 123 reg to change the name servers they were not using namesco name servers they were using 123's.
Do I want to change the name servers to the new name servers or not? I'm a bit confused as i was expecting to see namesco names servers?
I'm currently using the ones my registrar offers (Domain Site). But it just happened that they had an outage (they were down for a few minutes).
I'm looking for a more reliable solution. I could get dedicated servers where I'm hosting my servers, and I could also get services (like UltraDNS).
Is that possible to have ns1.mydomain.com ns2.mydomain.com
Two differnet severs that means each having two different IPS?
If so how?
the reason I ask is that I see a lot of hosting companies have thousands of users and many severs but they all ask their customers to point only to two name server ns1 and ns2
If you are located in the UK: Which manufacturers/sellers for dedicated servers can you recommend?
So far, I am sympathising with Dell. Any other good opportunities in a similar price range?

Say you are renting 2 (or more) dedicated web servers. How do you go about getting it so that www.yourdomain.com goes to one of the web servers? Do you need a 3rd server to redirect the request, or what?
