[Gluster-devel] [Gluster-users] PLEASE READ ! We need your opinion. GSOC-2014 and the Gluster community

[Jay Vyas]

I vote for 3,2,1 : 

Best: the accelerator looks cool and would be awesome for supporting hi throughput  workloads w/ different consistency gaurantees. In hadoop this could be valuable I think when we want fast ETL but can wait a few seconds for files to b available in global namespace 

2nd best: split brain project.  Id spin It... think best to focus on good tests for this type of thing, maybe even reproducible VM testing using vagrant or docker, to demonstrate distributed bugs like this if possible.

By the way .... Just to confirm that This is all you needed...I missed this thread earlier . We need more Gsoc participation , right? and we have 3 projects we need to vote on? Thanks for bringing our attention to  this by the way.!

This is specially important because it has a HUGE impact on Total Cost of Implementation (customer side), Total Cost of Ownership, and also matching what the competition has to offer. Among other things, it would allow gluster to implement a RAIDZ/RAID5 type of fault tolerance, much more efficient, and would, as far as I understand, allow you to use 3 nodes as a minimum stripe+replication. This means 25% less money in computer hardware, with increased data safety/resilience.

Some storage solutions out there offer an "accelerator node", which is, in short, a, extra node with a lot of RAM, eventually fast disks (SSD), and that works like a proxy to the regular volumes. active chunks of files are moved there, logs (ZIL style) are recorded on fast media, among other things. There is NO active project for this, or trello entry, because it is something I started discussing with a few fellows just a couple of days ago. I thought of starting to play with RAM disks (tmpfs) as scratch disks, but, since we have an opportunity to do something more efficient, or at the very least start it, why not ?
