Is there a document with some guidelines for setting up bricks with tcp or rdma transport? I'm looking at a new deployment where the storage cluster hosts connect via 10GigE, but clients are on 1GigE. Over time, there will be 10GigE clients, but the majority will remain on 1GigE. In this setup, should the storage bricks use tcp or rdma? If tcp is the better choice, and at some point in the future all clients are 10GigE, should the bricks be rebuilt with rdma? Are the...

I have a beefy machine (Intel dual-quad core, 16GB memory 2 x GigE) I have loaded RHEL5.1-xen on the hardware and have created two logical systems: 4 cpus, 7.5 GB memory 1 x Gige Following RHEL guidelines, I have it set up so that eth0->xenbr0 and eth1->xenbr1 Each of the two RHEL5.1 guests uses one of the interfaces and this is verified at the switch by seeing the unique MAC addresses.

Hi everyone, here's my problem: I have a fast server (dual Xeon E5-2620, 64 GB RAM) with a fast RAID array (24 disks, RAID-6, more than 2GB/s read/write local performance, XFS filesystem) and fast network : dual 10GigE (myri10g) and 40GigE (i40e). It's running Debian 8.11, tried various kernel versions (currently 4.4.x, but 4.9 isn't any better). It's slow as dead snails in molted mollasses using samba. Everything else is fine: * from a windows PC with a 10GigE card, using ftp.exe and vsftpd, I...

Andre, Are you going to have time to MFC things from -current for auto-tuning -stable before 9.2? I fear (maybe unnecessarily?) that we are about to ship yet another release that can't do basic 10gigE when sufficient memory exists. If you don't have time, then let me know and I'll see what I can do. -- Alfred Perlstein VP Software Engineering, iXsystems

...re success), amd64, pure vanilla kernel.org version. Distro Debian squeeze amd64, samba 2:3.5.6~dfsg-3squeeze5 The client is an opteron dual core machine running Win7 64 bits. This is by far the best performing CIFS client I've tested, software wise (see below). The systems are connected in 10GigE ethernet using Myricom Myri-10G dual ports (only one port used) through a Fujitsu 10GigE switch. I first tested the same client to the same server using Linux (same configuration as the server) and netperf, then NFS, then cifs mount. Netperf (TCP_SENDFILE test) gives more than 9500 Mb/s both dir...

...would be responsible for most of the network traffic associated with ocfs2. Correct? Is DLM traffic the same for a READ as for a WRITE? Does ofcs2 itself send messages for reads and/or writes in normal use? Any metrics known relating IO size to network traffic? Guesses? If I'm using a 10GigE network, would I have a need for adding another NIC and bonding? Thanks, -PWM

...ore recent version there, 4.6.7 OK I'll try it, but that doesn't really explain why it's so slow, while it's completely OK on other similar or slower machines... Actually it's the first time ever, with any Samba version (including 3.6.x) that I have such a bad performance on a 10GigE equipped system. I even usually got better performance with bonded Gb interfaces 8 or 9 years ago... -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac at inte...

Hi All, We looking for suggestions on dealing with mellanox drivers in CentOS 6.7 We tried installing mellanox drivers (MLNX_OFED_LINUX-3.2-2.0.0.0-rhel6.7-x86_64) on a Quanta Cirrascale server running Centos 6.7 - 2.6.32-573.22.1.el6.x86_64. When we rebooted the machine after installing the drivers, it went into a kernel panic for every installed kernel except for Centos 6.7

Hai, Ok, so you have 3 the same machines and only one is slow. Thats important info. Did anything special happen with this server. For example 2 servers got a new install and this one had an upgrade (or sort of upgrade) from the "old" server? Or you configured the new server in an other (ad site) and moved it to the new location. In tring to figure out, where what happend, so we

Any new iPXE driver developed commercially will be tested and expected to reach 1000Mbps or have good reasons for not doing so. You can construct an ipxelinux.0 as an updated r...

...e same Debian OS (8.x). Each one is on a different network, etc. But similar machines have similar performance, up to this time :/ However I've installed several hundred storage servers and that's the first time I've seen this. I've never ever had this problem of low performance on 10GigE, and even less of this low performance in CIFS only, whatever is the samba version. Even back in 3.x days. -- ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | <eflorac a...

First off, I'm a little confused but I've been trying to do some research and still have some questions... (please forgive me!) I'm trying to figure out the "best" (ie. fastest) way to connect from Ubuntu to Windows Server 2008. I can use SMB, SMB2, or NFS.
