How does Oracle Storage Cloud Software Appliance – Cloud Distribution work?

A.
It copies data from specified storage volumes in Oracle Compute Cloud Service to
Oracle Storage Cloud Service on demand.

B.
It stores all data in storage volumes attached to the Oracle Compute Cloud Service VM
that hosts the appliance and uploads only infrequently accessed data to Oracle Storage
Cloud Service.

C.
It immediately writes data to containers in Oracle Storage Cloud Service as soon as
applications write files to the appliance.

D.
It uploads data to Oracle Storage Cloud Service according to the synchronization
schedule defined by the user.

E.
It caches data written by applications in storage volumes attached to the Oracle Compute
Cloud Service virtual machine (VM) that hosts the appliance and copies all the data
asynchronously to Oracle Storage Cloud Service.

hi,

The answer correct is E, here information.

http://docs.oracle.com/en/cloud/iaas/storage-appliance-cloud/sfsug/oracle-storage-cloud-software-appliance-cloud-distribution.html

How does the appliance work?

You provision Oracle Storage Cloud Software Appliance – Cloud Distribution on one of your Oracle Compute Cloud Service instances and configure filesystems, each of which maps to a container in Oracle Storage Cloud Service. You then mount these filesystems, using the NFS v4 protocol, on the client Oracle Compute Cloud Service instances that you want to provide shared file storage for. Currently, the appliance is supported for Oracle Linux instances of Oracle Compute Cloud Service.

When applications running on the client instances write data to the mount points on the instance, the data is cached on the appliance instance and then uploaded asynchronously to Oracle Storage Cloud Service. Frequently accessed data is cached on the appliance. You can configure the appliance cache size.

Your applications enjoy read and write performance that’s comparable to the performance when using network-attached storage (NAS). And you get the benefits of low cost, infinite scale, and reliability of Oracle Storage Cloud Service.

The following figure shows two Oracle Compute Cloud Service instances sharing access over NFS to data stored in Oracle Storage Cloud Service:

B is the correct answer. Please read the wording. In E it says async BUT all data – Nope; Not all data only not frequently used data. B says it correctly.
