→iSCSI/AoE Support
* Resources: an ARM system, CDOT PC systems
* Expected result: iSCSI on ARM fixed and tested, and changes pushed upstream; AoE tested on ARM; report comparing iSCSI and AoE performance on ARM; ARM buildsystem configured to use a high-performing iSCSI or AoE storage solution in place of the existing NFS system
* Initial contacts: [[User:Chris Tyler|ctyler]], [[User:Paul.W|PaulW]]
== CreateRepo Performance Improvements ==
The ARM build farm consists of the koji-hub/koji-web system (HongKong, x86_64) and a group of ARM builders. The HongKong host also handles the CreateRepo tasks, which heavily load that machine. It might make sense to move those tasks to another machine, but doing so makes the CreateRepo jobs take a lot longer (15 minutes on HongKong vs. 55 minutes on another x86_64 server). This is presumably due to the overhead of sharing files between HongKong and the other server over NFS on the 100 Mbps Seneca network.
This project involves figuring out how to run the CreateRepo jobs more quickly. Possible solutions include a 1 Gbps LAN, a redistribution of the file storage or a change to a different file storage technology, or optimizing the CreateRepo tasks on HongKong for best speed.
* Maximum number of students: 1
* Skills required: system administration, benchmarking
* Resources: CDOT server systems (HongKong, Ireland, Scottland)
* Expected result: significant reduction in CreateRepo times, especially when multiple CreateRepo tasks are running
