    iSCSI

    It was just an example. By the way, FC are very expensive.... I'll prefer a SAS DAS (usually 12gbit) connected to a couple of SAN gateway. On the gateway I can install two or three 4gbit ethernet port in teaming/bonding. 12gbit in iSCSI for each server....

    cpulimit

    Hi, I will get a dual QuadCore Xeon server. I would like to create 10 VM machine over it. How can I calculate the cpulimit for every virtual machine? For example, if I want to create every machine with 10% cpulimit, how can I set this in virtuozzo? In a dual quadcore environment, is correct to...

    iSCSI

    So you think that I can access to the iSCSI san via host server and then I can create 10-20 LVM volumes that are connected to each VM via single iSCSI connection? If yes, an iSCSI SAN with support to 16 host can handle 160 VM (10 VM for each host)

    iSCSI

    Hi all. One of our technician told me that with an iSCSI san, every virtual machine on a host must be connected directly to the iscsi san. For example, if my san will support a maximum of 16 hosts, i can have just only 16 virtual machine connected to it. With a fiber san, only the host is...

    Cluster & Live Migration

    So, in a two node cluster environment, with 8 gb ram on each cluster node and 8 machine (1gb ram) over each cluster node, is not possibile to migrate ALL virtual machine from one node to the other node due to the lack of ram over the destination node. In this case, should be better to create a...

    Cluster & Live Migration

    two node cluster. node 1 with VM1, VM2, VM3 node 2 with VM4, VM5, VM6 six different virtual machine and not 3 virtual machine with failover capability only. I know. But if one node will fail I need to migrate virtual machine from that node to another node until first node will goes up again...

    Cluster & Live Migration

    Let's assume that a customer is downloading a big file from rapidshare or any other service that has a "tocken" for download. After that token, download is expired. If suspend time will go over the customers token, download shoul be restarted again, right? Just to know.... is possibile to...

    Cluster & Live Migration

    Yes, I'm confused. But what does it mean "suspend time" ? During this time is non possibile to use a virtual machin or continue to download a file from internet?

    Cluster & Live Migration

    That's not a live migration if a VM is suspended.... EDIT: is possibile to setup up a two-node cluster with different machine over each node? Last question: if i'll buy two 8GB servers, and I'll create 8 VM with 1GB ram over each server, in case of migration of 1 server over the second one...

    Cluster & Live Migration

    Thank you for the clear response. But during rsync copy, what happens to the client? New data are store in new server or in old server? For example, customers will downlaod a huge file from internet during a live migration. It has a 40GB virtual machine full of file, rsync copy will take a long...

    Cluster & Live Migration

    Hi all. I'm new to virtualization and proxmox and I have a couple of question: We would like to set up a two node cluster made with a pair of DELL PowerEdge 2950 with 4x146GB SAS 15k rpm disks. We have not a SAN, DAS, NAS or a shared storage. Each server will have it's disks inside. Is...
