November 16, 2010, 4:46 PM — In my last blog, I introduced the concept of the data services engine (DSE), a modular building block of hardware and software that provides all the core functions for data management within an optimized data center. Most data centers still use multiple single-purpose solutions to provide the critical IT services of storage provisioning, data protection, data replication and disaster recovery for the organization's data assets. The DSE provides a more cost-effective and efficient methodology for providing these services by combining all the required functions into a single solution.
The key technical innovations that make the DSE possible are:
* Multi-protocol connectivity (FC, FC0E, iSCSI, IB, NFS, CIFS)
* Global file system
* Blade servers
* WAN optimization (sub-block level delta versioning and peer-to-peer proxy enhancement)
* Sync and async data replication with guaranteed write order fidelity
* Snapshots
* Data encryption
* Virtualization for servers and storage
* Storage pooling, tiering, mirroring and classification
