[Users] SSD Caching

[Russell Purinton]

[20:42] <sonicrose> is anybody out there using a good RAM+SSD caching system ahead of gluster storage?
[20:42] <sonicrose> sorry if that came through twice
[20:44] <sonicrose> im thinking about making the SSD one giant swap file then creating a very large ramdisk in virtual memory and using that as a block level cache for parts and pieces of virtual machine disk images
[20:44] <sonicrose> then i think the memory managers would inherently play the role of storage tiering ie: keeping the hottest data in memory and the coldest data on swap
[20:45] <sonicrose> everything i have seen today has been setup as   "consumer"  ===>  network ====> SSD cache ====> real disks
[20:45] <sonicrose> but i'd like to actually do "consumer" ===> RAM+SSD cache ===>  network ===> real disks
[20:46] <sonicrose> i realize doing a virtual memory disk means the cache will be cleared on every reboot, and I'm ok with that
[20:47] <sonicrose> i know this can be done with NFS and cachefilesd(fscache), but how could something be integrated into the native gluster clients?
[20:47] <sonicrose> i'd prefer not to have to access gluster via NFS
[20:49] <sonicrose> any feedback from this room is greatly appreciated, getting someone started to build managed HA cloud hosting
