[one-users] paper about the AoE storage driver in OpenNebula

[Sándor Ács]

Dear Community,

let me share with you the "Block Level Storage Support for Open Source IaaS
Clouds" paper (published at PDP2013), that describes the AoE storage driver
(http://dev.opennebula.org/issues/1648) and its evaluation.
*
*
*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. *
