[20:42] <sonicrose> is anybody out there using a good RAM+SSD caching syste=
m 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 th=
en creating a very large ramdisk in virtual memory and using that as a bloc=
k 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 "consu=
mer" =3D=3D=3D> network =3D=3D=3D=3D> SSD cache =3D=3D=3D=3D> real disks
[20:45] <sonicrose> but i'd like to actually do "consumer"
=3D=3D=3D> RAM+S=
SD cache =3D=3D=3D> network =3D=3D=3D> real disks
[20:46] <sonicrose> i realize doing a virtual memory disk means the cache w=
ill be cleared on every reboot, and I'm ok with that
[20:47] <sonicrose> i know this can be done with NFS and cachefilesd(fscach=
e), 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, get=
ting someone started to build managed HA cloud hosting
