[PATCH][ioemu] support the assignment of the VF of Intel 82599 10GbE Controller
The datasheet is available at http://download.intel.com/design/network/datashts/82599_datasheet.pdf See 'Table 9.7. VF PCIe Configuration Space' of the datasheet, the PCI Express Capability Structure of the VF of Intel 82599 10GbE Controller looks trivial, e.g., the PCI Express Capabilities Register is 0, so the Capability Version is 0 and pt_pcie_size_init() would fail. We should not try to expose the PCIe cap of the device to guest. Signed-off-by: Dexuan Cui <dexuan.cui@intel.com> diff --git a/hw/pass-through.c b/...

How to make a network interface come up automatically on link up?
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 /etc/sysconfig/network-scripts/ifcfg-eth2 , setting its IP address,...

virtio nic dosent use 10gbe speed.
Hello all. We are moving from Xenserver 6.5 environment to KVM because we can't use 10gbe speed in our VM's so we decided to test KVM. To inicial test I've create script, using qemu commands, to build two VM's and test the nic speed. Each VM has one nic, using virtio, into it own bridge. In this bridge we associate one 10gbe physical nic. They can communicate each other....

SSD over 10gbe not any faster than 10K SAS over GigE
GigE wasn''t giving me the performance I had hoped for so I spring for some 10Gbe cards. So what am I doing wrong. My setup is a Dell 2950 without a raid controller, just a SAS6 card. The setup is as such : mirror rpool (boot) SAS 10K raidz SSD 467 GB on 3 Samsung 256 MLC SSD (220MB/s each) to create the raidz I did a simple zpool create raidz SSD c1xxxxx c1xxxxxx c1xxx...

New 10Gbe adapter on lustre client brought down switch due to broadcast traffic
Hi Guys, I had a situation yesterday where I had a 10Gbe adapter on my lustre client configured but not active (the cable was plugged in and had link but the port was down) and this actually brought down our cisco switch. This is a new port that I am setting up. The reason why the switch went down was due to the amount of broadcast traffic coming from...

questions from a 10GbE driver author
Hi, I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow? A...

ssh / scp slow on 10GBE
Hello list, right now SSH Tunnel / scp is reaches just around 76Mb/s on my E5 Xeon using AES-NI but openssl reaches around 600-700Mb/s using 128aes-cbc cipher. As far as i understand http://www.psc.edu/index.php/hpn-ssh this is due to very small buffers in ssh / scp. Is there any work on this? Like autotuning the buffer size? Are there plans to integrate the hpn patches? Greets, Stefan

Bonding modes
I have a bonded interface running in mode 1 which is active/passive and no issue with this. I need to change it to mode 0 for active/active setup. Does mode 0 is dependent on the switches configuration? My setup is: 2 links from bonded interface is connected to different switches. When I change to mode0 from mode1 , bond0 is not coming up. These are the steps I performed 1) changed to options

Best practice settings for channel bonding interface mode?
Hi, may be there are some best practice suggestions for the "best mode" for channel bonding interface? Or in other words, when should/would I use which mode? E.g. I do have some fileservers connected to the users lan and to some ISCSI Storages. Or some Webservers only connected to the LAN. The switches are all new cisco models. I've read sone docs (1), (2) and (3) so the theory

PXElinux boot sequence with multiple ethernets
Hello, I am attempting a PXE boot between two systems, each with multiple network cards. While there are a total of 8 ports on each computer, only two (each) are connected as follows: Boot Server eth0 - 10GbE fiber channel (private to the set of computers being managed) (Qlogic) eth4 - 1Gb ethernet (public and out of my sphere of management) (NetExtreme II) Boot Client eth4 - 10GbE fiber channel (same private as above) eth0 - 1Gb ethernet (same public as above) T...

Opinions on bonding modes?
I am working on setting up an NFS server, which will mainly serve files to web servers, and I want to setup two bonds. I have a question regarding *which* bonding mode to use. None of the documentation I have read suggests any mode is "better" than other with the exception of specific use cases (e.g. switch does not support 802.3ad, active-backup). Since my switch *does* support

any more efficient way to transfer snapshot between two hosts than ssh tunnel?
Assuming in a secure and trusted env, we want to get the maximum transfer speed without the overhead from ssh. Thanks. Fred -------------- next part -------------- An HTML attachment was scrubbed...

how many hosts could be down in a 12x(4+2) distributed dispersed volume?
Dear All, I just implemented a (6x(4+2)) DISTRIBUTED DISPERSED gluster (v.3.10) volume based on the following hardware: - 3 gluster servers (each server with 2 CPU 10 cores, 64GB RAM, 12 hard disk SAS 12Gb/s, 10GbE storage network) Now, we need to add 3 new servers with the same hardware configuration respecting the current volume topology. If I'm right, we will obtain a DITRIBUTED DISPERSED gluster volume with 12 subvolumes, each volume will contain (4+2) bricks, that is a [12x(4+2)] volume. My questio...

Infiniband performance issues answered?
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>

Solarflare SFC9000 direct connection
hi guys I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too. I'm trying poor man's setup to get the servers onto 10GbE network. Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast mode. And it all seems to work, they ping each other, iperf okey. The problem, b...

Improving 30-40MB/sec Sequential Reads
...9;ll delve into what I've tried/tinkered with below. The hardware on My FreeNAS machine is an Avoton C2550, 32 MB ECC RAM, 7x2TB HDDs in raidz2 config and using a pair of SSDs as cache devices for ZFS. The motherboard has an onboard Intel Gigabit NIC and I've recently added a Chelsio T320 10Gbe card as well. I've benchmarked the local disk read speed and I get around 565MB/sec reading a file that far-exceeds the NAS' RAM. I've also used iperf to confirm the network interfaces aren't the bottleneck. A single instance/thread of iperf pushes 921Mb/sec over the 1Gbe line and...
