Nexenta's new Namespace Cluster promises to scale out storage capacity and performance while also allowing users to connect to thousands of nodes to work together as one file system.
I'm trying to use WMI Explorer to query the root\MSCluster namespace on various hosts to obtain cluster resource group and resource object data. I can access the namespace with no issue on Win2K3 cluster nodes but am getting an access denied error attempting to connect to Win2K8 and Win2K8R2 nodes.
I am trying to setup a failover cluster with two nodes. After running the validation tests, the storage sections had many warnings. The next step after creating the cluster with two nodes on the same domain is to add storage. I right click on storage and choose "add a disk", then I get the following error:
Nexenta, the OpenSolaris based distribution has released the fourth alpha of their server-oriented distribution. Nexenta uses Open Solaris as it's base and includes a number of Ubuntu software packages which make it a rather unique platform.
We have a cluster with multiple ubuntu machines which are connected to a shared SAN storage. Initially we were using OCFS2 as file system but we were hit with so many issues and we couldn't find proper documentation or support therefore we have decided to move to another cluster system.
Do you have any idea how to check the performance of HPC cluster having mpich on top of centos 6.2?
Are there any standard programs (like FFT, graphics rendering etc) to check the performance of mpi cluster with single node and multiple nodes?
Can we check the performance of single core and dual core?
Can we benchmark small cluster of 4 nodes or is be
I am trying to tune my NFS performance, but for some reason nexenta is ignoring whatever I specify in /etc/system. In the following screen shot it becomes apparent that my manual settings are not being picked up, why? I realize the web gui does give me the option of specifying the tcp_recv_hiwat and tcp_xmit_hiwat, but what about the other variables?
I am building a cluster (without ROCKS, I am doing this for educational purposes). I have been reading from numerous places that this is an easy thing to do but it doesn't seem so (or perhaps I have been reading something wrong). I am making a cluster with the Debian operating system and I know about the NFS, SSH and MPI installations that need to occur in order to get it to work.
