I have linux dedicated server and like to setup dual NIC cards for extra redundancy.. in case one NIC card fails.
I have no idea how I can set this up..how can I do this? I understand at least I need swtich.. and?
i have a webserver (mailserver) already running example ABC.com now i want to buy extra server that will be used only to send newsletter to members of ABC.com. Is it possible to do it? Also i dont want to break the existing mailserver as it is used by staff so this new server has to operate independently but of course this has to appear and has to be legitimate.
One of my idea is to setup a subdomain for ABC.com lets say mail2.abc.com and point to a new server but again how it will appear if i send email from info@abc.com when its subdomain!
If you have experience with large mysql databases please share your thoughts about a new MySQL server. If all other parameters are the same, what is better for a 6-10 GB MySQL db, dedicated server?
Dual XEON or Dual Opteron 2212 Dual Core Processor?
Also, any advice on suggested RAM, partitioning, OS, etc. are welcome. Current MySQL version used is 4.1.21.
I'm about to purchase a 2nd server to be used as a database/app server alongside my current server (of which will be the web server).
I wish to use 2 x 146GB 10K SCSI hard disks (in RAID 1) on the database server, but will be keeping 2 x 320GB SATAII 16M in RAID 1 on the web server. Will the SATA hard disks affect the performance / effectiveness of the SCSI disks or will I benefit from SCSI even though they're only in the database server?
Also, I'm going for 10K hard disks over 15K because they $20 per month cheaper and it's already expensive ($150 p/m for the two 10K or $170 p/m for 2 x 15k). Taking into account the already hefty price, is it worth the extra for 15K?
I just added a database server in private network and moved the database for Vbulletin Forum to this server.
But some how, the Forum is loading extremely slow compare to before ( when it was on the localhost). Also, Compare to another website on server (using local database) it is much slower.
One thing good is the load is lower
2 servers are connected via 10mbs private link, both servers are at Softlayer.
webserver: Opteron 170, 2GB RAM, 73GB SCSI 15K
database: Quad Xeon 3220, 2GB RAM, 73GB SCSI 15K.

I want to colo dual xeon 3ghz/ 2 x 250 sata drive and Dual core 3.0 / 2 x250 Sata drive.
How much amp these server need? One colo company said 4amp for dual and 2 for dual core. Do I need 6amp for 2 servers? Rack comes with 15amp so I need half rack?
Not sure on industry standard here, but I am now curious about this issue.
I placed an order with a company, paid for a setup, first month etc. On receiving the order, I was given the wrong product. Which was fixed for me within a few days. I was happy to even pay for this which the host declined.
Fast forward a week or so. Still in the first month, and issues are still not resolved.
I've now removed credit card information from the billing system (yes I know, shouldn't do it) with good reason. I expected to have to pay another month, and that was fine.
Anyway, month ends and I am charged on a credit card that was removed from the billing system. When confronted about it, I was told standard practice. I think this is highly unethical to hold details after they had been removed.
Is this indeed standard practice in this industry? Do a majority of other hosts do the same thing?
Now again, I am only to happy to pay another month, just not from a credit that was removed, which is why it was removed. I would've sent a check, or done a deposit. I do understand that fraud, etc is very high in this industry. I have a host or two not give me service because of the email address I used during sign up, but when changed, I received service.
i have several servers here but only basic knowledge about raid
My understanding of raid is like this
I have a server with 4 disk on it and if i put it in raid 1 and want to install an OS i can only see 2 of the disks right? (thats how it works on my ibm server)
But with my other servers if i put them in raid 1 and want to install OS i can still see all 4 disks thats not right is it?
anyone that can recommend a pci raid card for 4 sata2 disks?
Which one you suggest for running database server and VPS's?
Dual Xeon3ghz 1mb dual core vs Quadcore 6600 2.4ghzx4 core 8mb.
The issue we have is that server1 (web) has the load very high, compared to server2 (mysql). Sever2 stays at 0.5 during peak time.
I must mention that we have very heavy traffic hits only for 30min/day, then things calm down.
I simple diagram would be:
[USERS] <= NIC1 => [SERVER1 WEB] <= NIC2 => [SERVER2 MYSQL]
So I think we can install a load balancer and upgrade the NIC cards, in order to solve this problem.
What I thought is this:
In server1 (web) install 2 NICs, one facing the users and one facing the server2 (mysql).
Currently we have a 100MB NIC card into each server.
The 95th is way to high at peak time, over 500MB so I was thinking on installing a 1GB NIC facing the server2 (mysql).
My question is:
What is the best way to install a second NIC into an existing configuration?
Do I need a Cisco 2970 switch?
Example:
[USERS] <= NIC1 | NIC3 => [SERVER1 WEB] <= NIC2 => [SERVER2 MYSQL]
to setup a Windows server that can support the failure of the switch that comes before it in the network diagram. The idea would be that if the 15A circuit the switch was on failed, or the switch just died, the server would still be online.
I already have two switches in spanning tree just before the server. Is there a way to assign a single IP to the server on both its network cards and connect each card to a different (spanning tree'd) switch?
I am setting up an internal network for management only. So, assign an IP for the second NIC, and activate it, but it seems not working. I have tried this
#ifconfig eth1 192.168.2.14 netmask 255.255.255.0 broadcast 192.168.2.255
#ifconfig eth1 up
checking dmesg, it shows the NIC is up
# dmesg
ADDRCONF(NETDEV_UP): eth1: link is not ready
tg3: eth1: Link is up at 100 Mbps, full duplex.
tg3: eth1: Flow control is off for TX and off for RX.
checking routing table seeing the 192.168.2.x routed through eth1
# route -e
192.168.2.0 * 255.255.255.0 U 0 0 0 eth1
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1

Will the Dell-made PERC 4 DC (or SC) RAID cards work in Sub v20z servers?

From what I gather, it should in theory work, as they are both PCI-X and Ultra320 SCSI ... right?
If they won't work, can anyone recommend any raid cards that will?
With Ubuntu getting more and more popular, anyone knows what are the raid cards that support Ubuntu?

what happens when I have 2 DNS servers on my domain and 1 fails?
around 50% of the access fails... or they detect DNS timeout and try the other one, so 50% of the access would just take more time?
after months of disruption moving servers into a new data centre, our once reliable colocation company has now had nearly 6 hours downtime in the last 16 hours. So much for network redundancy.
View 5 Replies View Relatedim now having a second server located somewhere else then my first one.
I'd like to setup something to have redundance. if server1 goes down or even if it's too much loaded server2 take the charge.
How can i do this?
let say im having a domain "mydomain.com"
Server1 ip: 10.0.0.1 (Services; Apache, DNS)
server2 ip: 192.168.0.1 (Services; Apache, DNS)
mydomain.com nameserver would be.
ns1.mydomain.com -> 10.0.0.1
ns2.mydomain.com -> 192.168.0.1
Now will i have to create 2 NS record on both server plus A record.
I cant understand this part ?
Now how would i setup bind so they replicate zone btw each other?
Basically have 2 hosting accounts at different providers...each set-up for the same domain name...and then somehow wtih DNS make it so if host #1 goes down traffic goes to host #2 (which would basically be a splash screen explaining that host #1 is down and will be back soon).
DNS isn't my strong point, but I do know you can do this with MX records...so if the first server fails it tries the next until it gets a working one or reaches the end of the list. I'd just like to do it is A records.
It wouldn't be as simple as setting the nameservers like this would it?
ns1.host1.com
ns2.host1.com
ns1.host2.com
ns2.host2.com
Would it use the host1 nameservers as long as they're online, and if not failover to the host2 nameservers? If so, great, but what if the host1 nameservers are online but the server itself is not.
What are the smaller shops doing for switch redundancy? We have all our machines on dual Com Ed feeds but most switches in the $1k-$3k range only have one power supply. We recently had a power strip go flakey and of course the switch was plugged into it.
Is the best solution getting two switches and hooking each machine up to both? How hard is that to setup in Linux? I've used keepalived for whole machine failover but not for network failover.
I have multiple hosting plans with different hosts and in different areas. I also have some STATIC websites.
I would like to know if there is a way for me to make my website available on multiple servers in case one of them is down.
I thought of changing the nameservers of my domain to
IP1 Hosted on host 1
IP2 Hosted on host 2
IP3 Hosted on host 3
of course the files will be uploaded to all three servers.
Is it possible and how should it be done?
I host several web clients that were recently impacted by the crap at ThePlanet. As I think about how to be more redundant (and repetitive) I'm not sure of my options.
What's the best practice to ensure that if you have a server at a data center that goes out, that you can (somewhat) easily switch over to a different server? I suppose one solution is to have 2 servers at 2 physical locations, and then you could just change the DNS record in the event of failure, but is there another solution I'm not aware of? Is there a good resource I can goto to read up on this info?
I'm looking for a VPS running Windows Server (preferably 2008, but 2003 is also OK) with 4GB of RAM. Disk space, provided it's at least 50GB, and bandwidth, provided it's at least 100GB/month, aren't really that important.
I've been scouring WHT and Google for something that will meet my needs but have not yet been successful. Does anyone know where I can find such a VPS? Or is there nothing out there and should I concentrate on fully dedicated products?
Although I have switch to using VPS for some time, I still have a question in mind.
Most registrars need 2 ns which 2 IPs are sufficent. Why some hostings are giving 4 IPs?
I ever sign up with one hosting which give 1 IP. If a minimum of 2 IPs is needed, what else can I do other than pay money for an extra IP? Feel cheated.
