Optimization of iSCSI Remote Storage Access through Multiple Layers
2009
2009 International Conference on Advanced Information Networking and Applications Workshops
Preserved Fulltext
iSCSI has a problem of drastic performance deterioration in the case of longer-latency. Thus, we have optimized iSCSI remote storage access through multiple layers. ...
As a result, when RTT is 32ms, performance of the optimized iSCSI has achieved quadruple of that of the default iSCSI. ...

Congestion Window, one of TCP parameters, has a close relationship with system performance in accessing remote storage with iSCSI. ...
In this paper, we propose a dynamic Congestion Window control method to stabilize the uneven behavior of throughput observed on the iSCSI storage access, and examine the algorithms to make the Congestion ...

We propose a mechanism to share congestion information across multiple flows in "Fair-TCP" for improved performance. ...
SANs based on Fibre Channel have been used extensively in the last decade while iSCSI is fast becoming a serious contender due to its reduced costs and unified infrastructure. ...
However these TCP connections are treated independently: most TCP implementations keep state on a per-connection basis in a structure called TCP control block (TCB) or an equivalent construct and each ...
