Hi Everyone =3D !

Recently I am reading some =3D documents about vmeare virtual =3D flash and citrix =3D IntelliCache . I am wondering if we can add some feature like that =3D into ovirt .

Then I found something = =3D like bcache and flash cache.

After changing some cod= e =3D , I tried bcache in an old version of ovirt node . It works for just one = =3D node .

But when I add another = =3D node to the data center, the problem occurred .

When I write some data = =3D into node A, the data will be stored in node A’s cache and iscsi =3D server.

But the cache of node B= =3D does not know the change . the data in node B’s cache still the =3D old one.

In vmware’s =3D solution and citrix’s solution , it seemed they have some way to =3D solve this problem .

Do you have any idea = =3D ?

Thanks =3D
