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

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?
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]
We've been investigating software and appliances that would allow us a central, web based login to manage access and users to all the servers with IPMI cards. Does anyone use anything other than appliances from avocent or raritan?

View 14 Replies View RelatedWe had a problem on one of our servers and it was running RAID 1 with two 300GB SAS.
When I boot the server I have the following issue,
PXE:E61: Media test failure, check cable
I searched through all the net but couldnt find a solution that helped me.
Now I took one of the HDDs out and installed as slave on another Linux server. One of the HDDs says when I do /sbin/fdisk -l,
no partition table for /dev/sdb (something like that)
The other HDD have all the partition table,
/dev/sdb1
/dev/sdb2
/dev/sdb3
/dev/sdb4
/dev/sdb5
The big partition (probably when I have my data) is under /dev/sdb2, although when I try to mount that partition I get the following error,
mount: wrong fs type, bad option, bad superblock on /dev/sdb2
missing codepage or other error
In some cases useful is found in syslog - try
dmesg | tail or so
Is any command specific for mounting RAID partitions or the HD is gone ?
I really need the data that are inside it.
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?
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

Repeat those steps for other boxes, but when pinging, all return errors

With Ubuntu getting more and more popular, anyone knows what are the raid cards that support Ubuntu?
View 4 Replies View RelatedI have a question maybe someone can help with. Is it possible to set the IP address on a IPMI card before a system ships? That way when the customer gets it, it already has the IP address set to whatever was agreed on and they can log right in using that IP address?

I have linux dedicated server and like to setup dual NIC cards for extra redundancy.. in case one NIC card fails.

Purchased a dell PE2650 which has a perc 3/di controller for raid, server 2003 installs fine (downloaded a 60 day trial of standard/enterprise)
The problem is server 2008, when I insert the cd it just hangs (via boot) it loads within server 2003 (but due to the demo being enterprise/standard edition and 08 being web edition I cannot "upgrade" 03-->08)
I have upgraded the bios and all the controllers and it is still the same, I have even used the dell pre-OS installtion disk for the PE2650 and 08 but the screen remains the same, just the background image (grey) with no text and no movement.
Since 03 loads fine I assume it is due to a lak of driver support, (and within windows it mentions perc problems to load suitible drivers)
At the moment, I have switched to scsi drives, loading 03 on one disk and will try to load 08 (within windows) onto the second hdd and try to use drivers located on the disk.
Has anyone managed to load 08 web edition on a PE2650/other perc 3 device?
Will a Perc 5 raid card work in a non-dell Linux server? These cards can be found for about $100 on eBay, and are much cheaper than the Adaptec cards with similar features and ports.
View 5 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?

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

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?
