DAM Blueprint 6 Large Repositories

Avatar

Level 6

Hi,

On the Assets Deployment Blueprint on the Blueprint 6 for large repositories, it states:

"To deal with huge repositories, such as over 5 million assets, 10 million nodes, and 10TB disk size, in a costeffective
manner, split the persistent store and the data store (optimized for handling large binaries) onto
different media.
The persistent store requires very low latency I/O, hence local storage works best. For the data store, a higher
latency is acceptable. Consider sharing a networked or cloud storage solution like network-attached storage
(NAS) or Amazon S3 across all author instances.
A shared data store, along with the Experience Manager assets binary-less replication feature, reduces
replication network traffic because all instances can read the binary directly from the data store. However, this
approach requires running data store garbage collection (GC) on the instance that keeps references to all assets."

And it gives an example of the architecture with this diagram:

By the image it seems to be that we have two independent Author Instances sharing the same data store. Is this possible? Or for this scenario can I consider that they will be in cluster, so we need to use MongoMK? Or Would both be independent and be replicating to each other?

Any clues are welcome.

Thanks

Hi Francisco,

the document you refer to is from 2013[1], Most likely the scenario in the picture was for a cluster with shared data store[2].  As you know this topology no longer holds true for AEM6.

When using MongoMK, and you set up an external file store, then all the instances must point to the same location, as stated here[3], the content in this scenario is stored in MongoDB.
