One of the many features of Dell ObjectScale is its ability to deliver storage efficiency using XOR. To enable this feature, XOR requires three or more Virtual Data Centers (VDC) or sites (eight maximum) replicating data chunks between them. Within each VDC, multiple chunks are combined into a single chunk therefore reducing the storage footprint while providing the necessary site redundancy. The load balancing component of an ObjectScale solution leveraging XOR is essential to successful delivery.

When data is written to a site (VDC), that VDC becomes the owner of that object. When that object is read, it should be read from the VDC that owns it. If it is read from another VDC, that VDC must request the latest version from the owning VDC which will produce unnecessary overhead and latency on the ObjectScale storage solution. The Connection Manager delivers an S3 Optimized Scheduling method to ensure the accurate routing of object write and read requests. This method utilizes a URL Hash algorithm to distribute writes evenly across multiple sites and send all reads to the site owning the object. This purpose-built scheduling method delivers greater performance and optimization of the S3 traffic.
