Hello Davide, sorry it took a little time. When i tested from sds node 1 to sds node 2 i have 9,3 Gbit/s too. But when i test to my sdc i have only 3-6 Gbit/s. My Infrastruktur has four esx hosts, with 2 netapp filers with10 gb and few other iscsi stores. There runs a lot of  tasks and we have about 100 vms. I am not sure whether I get more throughput with iperf. I am disable all engery safings on my sds hosts. I'm still waiting for the third 10 gb card. In the moment i have destroy my cluster 😞 MDM to cluster, MDM role is not a Slave but a Tie-Breaker, King regards Stefan EDIT: the cluster problem are resolved

Hello, litte mistake, after uninstall mdm from cluster, i need to readd the mdm to cluster. I wanted to upgrade from ubuntu 14.04 to 16.04, but then I fixed the scaleio in the trialversion is not yet available. What have i do: - uninstalled emc software from node 1 - switched to one node cluster root@esther02:~# scli --query_cluster Cluster:     Mode: 1_node, State: Normal, Active: 1/1, Replicas: 1/1 Master MDM:     Name: Manager2, ID: 0x210c0653683e7121         IPs: 192.168.12.11, Management IPs: 192.168.12.11, Port: 9011         Version: 2.0.7120 - installed mdm MDM_IP=192.168.12.10,192.168.12.15 dpkg -i EMC-ScaleIO-mdm-2.0-7120.0.Ubuntu.14.04.x86_64.deb root@esther02:~# scli --add_standby_mdm --new_mdm_ip 192.168.12.10 --mdm_role manager --new_mdm_management_ip 192.168.12.10 --approve_certificate --force_clean You are about to clear previous configuration on this MDM. Press 'y' and then Enter to confirm.y Error: MDM failed command.  Status: MDM role is not a Slave but a Tie-Breaker He says the mdm is a tie-breaker. Here I know no further, Tie-Breaker was in the cluster the 192.168.12.13. I will reconnect the mdm to 3 node cluster. King regards Stefan

Hi Davide, great, many thanks again. My SDS are Ubuntu serves, i cannot disable delayed ack and nagle algorithm. The network cards from the sds server shows no TX or RX errors. I still had a 10 gb card from another server, after the installation had 3 Gbits/sec with iperf. For the other two SDS I have orderd 10 gb cards. I have installed on each sds server a second network connection. The last IO Meter tests: 29.000 IOPS and 115 MB/sec with 4 K 100% Read. I have full speed for 1 GB, 115 MB = 920 MBit. This performence its much better. Now i will waiting for the other two 10g cards an i will see the performence. Apparently 10 gb is crucial. I will report again soon. I have read your "Upgradepath" from ubuntu 14.04 to 16.04, would you recommend before the productive use to update the ubuntu and scaleio version? You have a similar infrastrucktur as we. King regards Stefan

Hi Davide, i am testing on physikal servers with ubuntu 14.04. I have problems to install the raid1 for the ubuntu system on lsi controller, and have now installed the system on ubunutu software raid. I do not know exactly whether that is decisive for the performance. The io benchmarks has i startet on windows server vm placed on the SSD StoragePool. Now the network connection from SDC to SDS are good for 1 Gb Network.

Hi Pawel, Paul, Davide, thanks a lot for your response. My idea is to use our old esx server for scaleio. The modells are - fuijtus rx 200 s6, - 96 gb ram, - lsi mega-raid sas-controller. Each node has at the moment one samsung sm863 ssd with 1,92 gb. Now the servers has 8 port gigabit ports, but only one are for the test in use. Jumbo frame are not activated. If we use scaleio productively, we buy 10 gb card with two interfaces, and for each host a second ssd with 1.92 gb. In the moment my infrastructur is hosted on a netapp 2240. We have about 100 vm. I already know that one 1 gb connection are not enough, but before it is determined whether or not we buy scale io are my means of testing limited. After i change the default IO scheduler "echo noop > /sys/block/sdg/queue/scheduler" i have max 972 iops / 3,86 MB no matter what test I do. S orry for my badly written english.   I will reboot the nodes and check the bios energy saving. Regards Stefan

Hello, i am testing scale io and have installed  3 node cluster with ubuntu 14.04. The mdm are installed with raid-1 on 10k sas disk. Each node has one samsung ssd disk with 1,92 tb for the storage. The network connection  is currently 1 gb.  Performance mode and RAM Cache is activated. When i testing with IO meter i have max. 11000 iops. Maybe I have a comprehension problem why the performance is so bad. I hopy anyone can help me Regards Sterfan
Hi Pawel, thank you very much. My download was the wrong version. thanks, regards stefan
Hi Pawel, thanks, but the download from this site is not possible for me I have only acces to Trial Version. Regards Stefan

Hello, i will testing Scaleio. Now i downloaded the installer packages for linux. I can only find the packages for Rhel, Sles and Xen, but not for Ubuntu. I have read Ubuntu is  supportet in Version 14.04. Where can i find the install packages for this distribution? I hope anyone can help? Regards Stefan
