Hi Everyone !
Recently I am reading some documents about vmeare virtual flash
splayKC&externalId=2058983> and citrix IntelliCache
<http://support.citrix.com/article/CTX129052> . I am wondering if we can
add some feature like that into ovirt .
Then I found something like bcache and flash cache.
After changing some code , I tried bcache in an old version of ovirt node .
It works for just one node .
But when I add another node to the data center, the problem occurred .
When I write some data into node A, the data will be stored in node A's
cache and iscsi server.
But the cache of node B does not know the change . the data in node B's
cache still the old one.
In vmware's solution and citrix's solution , it seemed they have some way to
solve this problem .
Do you have any idea ?
