Can anyone recommend a product that converts a DS3 to an Ethernet connection?
View 2 Replies View RelatedIn terms of storage, which will provide faster data transfer?
1. A NAS (e.g. Lacie or Thecus) with 1GB port connected to a gigabit switch
2. An external storage that uses USB 2.0 interface
3. An external storage that uses eSata inferface.
Assumption:
All of it use sata drives under a raid 5 configuration.
would you recommend some PCI with 2 or 4 Ethernet 10M ports?
View 1 Replies View RelatedSay I have my own office to start building out my own "mini" data center.
If I wanted a lot of bandwidth for the most reasonable cost, how do one go about buying bandwidth from various providers? What is Metro-Ethernet vs. say a DS3? I know there is Fractional DS3 (6 to 45mb/s) and then Ethernet services up to GigE. I'd rather not mess with BGP right now either.
If I am looking at 15-20mb/Sec of bandwidth, what would be a good route to go? My budget is about $1500/month for bandwidth and IP Addresses (I need 2 Full Class-C IP Spaces). I also want to be able to turn up speed as needed without a lot of hassle.
Is this a reasonable budget? And where would be a good place to start? Just call up like Level 3 or am I too small potatoes to even deal with?
What low-cost Gigabit Ethernet switch would you recommend for providing residential IP services to an apartment complex that is already prewired for copper Ethernet? My only real requirement is that is it a managed switch supporting QoS, capping, and has fiber uplinks.

I don’t know which one to look at or get?
i have recently get this server , we moved to this server in the same datacenter
Linux OS:centos 5.4

Software Version;csf firewall, ossec Intrusion Detection System, rvsitebuilder

yesterday the dc tech logged-in by ssh (root) cause we couldn't connect to the ftp box we keep our backup's (the new box couldnt connect to the ftp got time out)
They fixed it.
Today i got a time out and after 2 reset and restaring of services the server was back again.Then i got this messages and it still coming (3 hours now i get 1 similar message per 5 second )
Code:

Also the firewall stopped the port scanning from a server within the same dc.
I checked it on google and the explanation's varies but most say that is a problem of the router/switch or similar.
Say a server has 2 gig-e ports on board, and the OS
is using both. Can I still use IPMI feature? Or do I have
to get an additional ethernet card?
We're ready to setup 3-4 42U racks for servers and are in need of choosing Ethernet switches. What do you guys use and why?
I'm looked at Cisco switches, but lost in their product forest. I'm looked at Express 500, 2960 and 3750-E models. Is there any more difference (in exception of stacking, cli and hot-swap fan/psu) that I need to consider? Prices differentiate too much.
I'm also looked at Linksys/D-Link business products and they seems to have the same features as Cisco Express series, but only 50% cheaper.
I've a rack in the datacentre, and actually sharing the ethernet line with another partner's rack.
Something like:
Bandwidth -> Switch 1 -> Switch 2 (partner's rack)
Bandwidth -> Switch 1 -> Switch 3 (my rack)
After a previous uplinks issue, i'm never able to hit above 4Mbps of download speed to my home's cable broadband anymore. I have no idea whether it's because my partner capped my bandwidth from Switch 1, or his usage has increased such that it's affecting my traffic too. I can't be too concerned about it with him, as he's paying the bulk of the bandwidth costs.
For the whole rack, i'm not able to hit above 5Mbps accumulatively, and my normal bandwidth usage is only about 1-2Mbps.
So i'm thinking of getting another line for bandwidth directly from the datacentre to my Switch 3, perhaps starting from just 1-2Mbps only.
How will things improve? Just a silly thought, whether my total available bandwidth can now be 5Mbps + 2Mbps = 7Mbps.
We have a few CPanel servers, all with multiple NIC's. (2 Each)
We want to setup Eth0 to be the managment interface (ie. 72.2.24.x)
We want to setup Eth1 to be the Shared / Exclusive IP Nic (ie. 67.69.141.x)
Here is the issue, Eth1 is on a totally different Vlan than Eth0.. thus, isolating DDOS attacks, and any other type of traffic concerns for managment.. But, it also has a different G/W as Eth0.
how to check ethernet connections in debian??
my server has 2 nics, how do I view them and their usage uptime etc in debian stable
I wanna see if they are being used randomly (usage on both), or if it hasn't been already setup and I need to do it (found a tutorial on how to do this, but dont' wanna fix it, if it ain't broken)
We are in the process of buying a server to co-locate
All the server centre's we look at are trying to charge lots of money for firewalls
We have looked into renting and buying firewalls
but all the bought ones seem to be in the form of 1U
my question is this:
Is it possible to have a firewall that fits inside a 1U rack?
...something like a network card with an inbuilt firewall
does any hardware like this exist or will we need something that takes up a 1u space?
how can I change ethernet port speed. For example I want to change 100 mbit to 20 mbit. I m using centos 4.5 final.

In this chassis, I am going to be using an ASUS M2NPV-VM motherboard [url], and I'll be installing a 3ware 8006-2LP RAID card.
I just want to make sure that that RAID card will work with that motherboard, and also I want to verify that the Supermicro CSE-RR1U-X riser card is the correct model for this motherboard and RAID card.
I've got a couple of basic servers built in the supermicro mini 1U (CSE-512L-260B) chassis, but I've never had to deal with riser cards before, so I wanted to make sure everything is compatible and is going to fit correctly before I purchase them.
i have just installed esx server from vmware which as far as i know is a moded version of redhat. i just brought that lan card and put it in. when intsalling the os it seemed to pick it up straight away. and it wanted to use the tulip driver and infact on the driver cd tuplip is given. so i thought it was all well uptill i tried logging in through the browser insterface. it came up with nothing. so i did ifconfig which only showed the lo device. i then did a lsmod tulpis ind it brought up this.
vmnixmod size 3
mousedev

usb-uhci
usbcore
but no network drive.
im not very good with linuk so im not sure what the interface is called. i tried ifconfig eth0 up but i dont know how to check if its called eth0 or somehting else. their is no gui just a bash.
i then tried netconfig. it worked fine and i restarted the box. it still dident come up.
so i thought maybe the driver wasent installed after all so i went to the cd and got the file off it and when i typed in make i got

so now im stuck. i have no idea on what to do next.
i know this isent the speciality of thsi frum but you have helped me so many times before i thought i should give you a shot at this.
Thinking of entry-level collocation for a 1u or 2u 1750 or 2850 server (but not a separate hardware firewall at this point) I'm wondering if I should equip it with a DRAC card on a separate switch port ($10 more per month for an extra switch port). However one concern: how secure is a DRAC card? It would seem to allow you to login with a standard username and strong password, but I still fear it could be brute forced since I'm not aware of a brute-force-detection mechanism that would run on the drac card itself.
Is the only way I can use a DRAC card and feel secure about it to also have a box in front of the DRAC card to lock down and monitor access to the DRAC's IP? Or am I worrying over nothing (I'm not very familiar with DRAC cards yet.)
I've been reading more and more posts about how a quality network card is important. We build all of our servers from new, quality parts but honestly we always rely on the built in NIC on the motherboard (which are brand name motherboards, but nonetheless)
How can a lesser quality NIC effect a server other than total failure of network activity? What signs should we look for and what are quality brands? My first guess is dropped packets or low throughput. I've also heard of people saying that load can go up from a bad NIC - is there any truth to that?
I was wondering if anyone has had luck with 3ware 9650's in a RAID 10 to help bring down iowait?
I currently have a VPS node that see's spikes in iowait and i'd like to bring it down. I've been considering getting a 9650 in a JBOD setup (so then I don't need to reinstall the whole node) with a battery backup to enable the cache.
My two questions are:
- In JBOD, does the write cache enable at all?
- Would the write cache help bring down the iowait much?
Drive wise we have 4 x 500GB drives in a raid10 (soft for now).
