Abstract: Cloud computing is the dominating paradigm in distributed computing. The most popular open source cloud solutions support different type of storage subsystems, because of the different needs of the deployed services (in terms of performance, flexibility, cost-effectiveness). In this paper, we investigate the supported standard and open source storage types and create a classification. We point out that the Internet Small Computer System Interface (iSCSI) based block level storage can be used for I/O intensive services currently. However, the ATA-over-Ethernet (AoE) protocol uses fewer layers and operates on lower level which makes it more lightweight and faster than iSCSI. Therefore, we proposed an architecture for AoE based storage support in OpenNebula cloud. The novel storage solution was implemented and the performance evaluation shows that the I/O throughput of the AoE based storage is better (32.5-61.5%) compared to the prior iSCSI based storage and the new storage solution needs less CPU time (41.37%) to provide the same services.

Hi! do you use the oneimage create and do you use IMAGE_ID when you create a virtual machine? if you do, you will get a failed message when you create a vm. Because in my lxc driver, it firstly extract the image file after downloading it, and the judgment condition is that the suffix of the image file is tar.gz or not. OpenNebula's image manager will name the image file according to its rules,so my code doesn't distinguish it and it leads to a fail.

Thank you. Do you mean that if the host isn't busy and VCPU=4, CPU=1 and CPU=2 have the equal effect. So CPU has effects only when the host os is overcommited.

[one-users] why opennebula releases resources of vm after it is suspended?
Hello everyone: I am very confused opennebula will release the resources of the vm when it is suspended. It is clear that this design will lead to a problem when the vm will resume again but the host os has no enough resources to run it, for example, no enough memory. Currently，It looks likely scheduler only deal with deploy action and the scheduler is the only place to judge whether there aresufficient resources in the host. So when executing a migarate action, it doesn't to judge because scheduler doesn't deal with migarate action. The migarate action is successful although there aren't enough resources in the target host os according to theopennebularesourcesstatistical algorithms. I'm not sureI understand itright.
