similar to: OT: looking for network performance comparison chart

I have a recently installed Mellanox VPI interface in my server. This is an InfiniBand interface, which, through the use of adapters, can also do 10GbE over fiber. I have one of the adapter's two ports configured for 10GbE in this way, with a point to point link to a Mac workstation with a Myricom 10GbE card. I've configured this interface on the Linux box (eth2) using

In IRC today, someone who was hitting that same IB performance ceiling that occasionally gets reported had this to say [11:50] <nissim> first, I ran fedora which is not supported by Mellanox OFED distro [11:50] <nissim> so I moved to CentOS 6.3 [11:51] <nissim> next I removed all distibution related infiniband rpms and build the latest OFED package [11:52] <nissim>

Hey guys, I am running gluster over infiniband, and I have a couple of questions. We have four servers, each with 1 disk that I am trying to access over infiniband using gluster. The servers look like they start okay, here are the last 10 or so lines of a client log (they are all identical): 2008-10-07 07:18:40 D [spec.y:196:section_sub] parser: child:stripe0->remote1 2008-10-07 07:18:40 D

This post appeared on another forum: Will CentOS become obsolete now because of the changes Red Hat is implementing? Red Hat has changed the way it distributes Enterprise Linux kernel code in an effort to prevent Oracle and Novell from stealing its customers, making it more difficult for these competitors to understand which patches have been applied where. Some have speculated that the change

Hi all, Can anyone pleas tell me what would be best practice to use shared storage with virtual machines, especially when it involved high availability / automated failover between 2 XEN servers? i.e. if I setup 2x identical XEN servers, each with say 16GB RAM, 4x 1GB NIC's, etc. Then I need the xen domU's to auto failover between the 2 servers if either goes down (hardware failure /

Hi All, I recently got some IBM Xseries 335 servers 2nd hand, and noticed they don't have any graphics card. Some google searched indicate they only have an uplink port, which you could connect to another (other model) IBM server and use that as the head node. But, I don't have one available. It has 2x GB NIC's, and what looks like a management port, but I can't figure out how to

would like some input on this one please. Two CentOS 5.5 XEN servers, with 1GB NIC's, connected to a 1GB switch transfer files to each other at about 30MB/s between each other. Both servers have the following setup: CentOS 5.5 x64 XEN 1GB NIC's 7200rpm SATA HDD's The hardware configuration can't change, I need to use these servers as they are. They are both used in production

Hi all I hope anyone can help me with this. I'm trying to get vmware to play along nicely on CentOS 5.1 x64, but I get errors when I try and start a vmx image, or list them.

I'm trying to setup a LVM mirror on 2 iSCS targets, but can't. I have added both /dev/sda & /dev/sdb to the LVM-RAID PV, and both have 500GB space.

Hi all, Our intranet's WAN interface just stopped working yesterday, and I can't figure it out. The machine has a Gigabyte motherboard, with on-board RTL-8110SC/8169SC Gigabit Ethernet and D-Link PCI NIC for the LAN side. I can get into the LAN side without an issue, but can't see the WAN side at all. [root at intranet ~]# ifconfig eth0 up eth0: unknown interface: No such device

Hi all If I do a "dig mydomain.co.za" from a Linux server, how do I know which DNS nameserver returns the queries? I seem to have a faulty DNS server, but can't see which one, so I want to find out which nameserver (if there's 4 - ns1.myserver, ns2.myserver, ns3.myserver & ns4.myserver) returns the queries? -- Kind Regards Rudi Ahlers CEO, SoftDux Web:

Hi all I have a CentOS 5.1 x64 server, running Xen version 3.1.0-53.1.21.el5 & Windows 2003 VM.

Yet it doesn''t boot up ( I can''t connect to it via RDP). So, how do I debug it to see

Sorry about the previous post, I see the subject had a typo. So here's the correct one :) Does anyone know how to configure Postfix to use SMTP authentication on a relay host? i.e. I have a Linux server, running PostFix on an ADSL line with a dynamic IP. Thus I can't just send out emails from this server but need to relay it via our ISP's SMTP server, which is very unreliable. Now

I've run into some trouble with a new cPanel VPS, and noticed that it's running CentOS by default, installed via the CentOS http server.

Hi all, I need to setup a real bare minimum CentOS Virtual Machine, but with normal internet / network access. i.e. I need SSH, Mutt, Links, lynx, ping, tracert, dig, iptables, etc. Does anyone know where (if?) I can get a list of applications which gets installed with CentOS 6 if every option is deselected in the installer so that I can see what I can remove which isn't really necessary
