Some more performance tweaking options I have found that have boosted transfer rates to 600+ MegaBytes per second. Change Tcp Window Size to 256 KiloBytes Change the Max Segment Size or (MTU) to 256 KiloBytes These changes are best made using regedit and setting these as options for the...

Hi, I have a Dell perc H700 raid controller and I have configured it as a Raid 10 using the "ctrl + r" options during boot the drive appeared in Windows disk management as expected. I then created 1 simple volume for the full size as a GPT partition. Now that I have logged into the LSi...

In my experience well optimized software that can utilize all the available threads and can give huge performance improvements over higher clock speeds. This is not an area that I do much work in professionally however work loads that can be broken down into may parts and executed in parallel...

I have updated the IP's on each host so that they are now non routable :D

Thanks for the feed back, Currently both hosts are only connected to each other.

Infiniband Update After a few months of messing around with lots and lots of config options I have managed to get a sustained copy speed of 300MB + per/sec using IPoIB with 2 windows hosts, using a point to point connection. This is not great speed by infiniband standards but it is 3x times...

CPU usage is around 40% using the most recent FreeNAS on average

Hi, I would like to setup a reasonable performance storage system for home.I have the existing hardware set aside for the storage box its self. 2x Xeon X5355 2.6ghz 16GB ECC RAM Intel VSA5000 Motherboard (has 2 onboard nics) also 16gb is max supported ram. It has 2 4xpci-e and 2 pci-x slots...

Hi sorry in the delay replying. While testing I was able to setup the ping server on both systems and ping in both directions. However I also noticed that the adapters that I have give the option in the device manager to allow for "ETH" mode. The adapeters are MT25408 Voltaire branded but are...

I have looked at the firmware updates and there are updates that can be applied to the firmware. Interestingly the "vstat" command returns the wrong firmware version when compared to the "flint -d mt25408_pci_cr0 query" which seems to report that the firmware on the adapter is the same as the...

I did move the cables about yes just to check that the ports were which ones I thought they where, I had not checked the firmware versions so I will try that next.

looking at the logs although I am not sure what this means atm root@debian:~# tail -f /var/log/opensm.0x0008f104039a6376.log Mar 31 18:34:23 578846 [828C6700] 0x02 -> osm_report_notice: Reporting Generic Notice type:3 num:66 (New mcast group created) from LID:1 GID:fe80::8:f104:39a:6376 Mar...

I have also now updated the MTU for the 2 infiniband adapters using this command. However this does not seem to hvae worked for the live connection, Maybe a reboot will fix that. netsh interface ipv4 set subinterface "InfiniBand #2" mtu=4096 store=persistent "InfiniBand #2" This relates to...

I have changed the IP addressing so that its as follows The Debian host is as follows IB0 111.111.111.1 mask 255.255.255.0 IB1 11.11.11.1 mask 255.255.255.0 Windows 7 IB1 111.111.111.2 mask 255.255.255.0 IB2 111.111.111.3 mask 255.255.255.0 This way I can swap the cable at the Debian end...

Each host has 1 adapter which has 2 ports The Debian host is as follows IB0 111.111.111.1 mask 255.255.255.0 IB1 11.11.11.1 mask 255.255.255.0 Windows 7 IB1 111.111.111.2 mask 255.255.255.0 IB2 11.11.11.2 mask 255.255.255.0 Thinking about this as I type I do not...

I have started testing with Debian and a windows host..... if possible could you take a look at the output of the Debian commands and see if there is anything clearly wrong...... I have used this page and others as a rough guide...

I am planning to use CIFS from the ZFS box eventually... I have now got the cards in place and I am testing them between 2 windows hosts before messing with the Solaris ZFS box, one windows 7 x64 and 1 Windows 8.1 x64. The cards are detected and the drivers are installed for each. 1) I...

Thanks for the info. If I install the Subnet manger on the Windows host and get everything up and working and then need to reboot the Windows host, what happens to the connection? Does it ? 1) Re-establish the connection once Windows and the subnet are back 2) Require work on the ZFS box...

I am starting my first foray into infiniband and I am on the verge of purchasing 2 adapters and 1 cable, to create a point to point connection between a Solaris 11 ZFS box and a windows 7x64 box using 10Gbps infiniband. My question is are the adapters linked below and the cable linked below...
