EMC Documentum

Get more out of EMC Documentum without the costs and complexity of multiple repositories or specialized caching. Silver Peak accelerates Documentum over distance, shortening file transfers while eliminating more than 80 percent of the data from the wide area network (WAN). Remote insurance agents process forms faster and designers retrieve large CAD/CAM files in seconds, not minutes. With Silver Peak, IT can deliver a more consistent and more responsive EMC Documentum experience to every location. 

EMC Documentum allows organizations to simplify their information lifecycle and improve productivity by ensuring vital content is accessible to the right users across the enterprise. But as users work further away from the Documentum repositories, performance problems often emerge. Content may take too long to retrieve while the performance of other applications sharing the network with Documentum may suffer.

Increasing wide area network (WAN) bandwidth typically does not address the problem. Regardless of the amount of bandwidth, the throughput of the TCP stack underlying Documentum decreases substantially as delay increases. Even when distance is nominal, delay across WANs and particularly Internet virtual private networks (VPNs) may be longer than expected due to network congestion, routing policies, peering practices and other factors.

Enterprises also cannot expect a cloud provider hosting a Documentum repository to fix the problem as the causes of delay often lie in the Internet not the cloud provider’s network. Deploying repositories or EMC Documentum Branch Office Caching Services (BOCS) at each location can help, but at the expense of increased operational cost and complexity. 

Silver Peak improves Documentum performance and every other application. Where enterprises require distributed repositories, Silver Peak improves data replication between the locations by 20x. Customer experience shows that Silver Peak more than triples Documentum throughput and improves response time by more than 80 percent. More specifically, Silver Peak addresses the following network challenges: 

• Bandwidth – Silver Peak  byte-level deduplication  removes redundant data from the WAN. The first time Documentum sends data it is fingerprinted and compressed by Silver Peak. Subsequent requests are fulfilled by the local Silver Peak instance.  
• Latency – Silver Peak mitigates latency, enabling Documentum to operate more efficiently over distance using.  CIFS Acceleration  includes CIFS read-ahead, CIFS write-behind, and CIFS metadata optimizations  TCP Acceleration includes windows scaling, selective acknowledgements, and HighSpeed TCP. Latency is also reduced through packet coalescing, which re-packages multiple smaller packets into a single larger one, and through Dynamic Path Control, which selects the fastest path to a remote location.
• Congestion – Silver Peak makes Documentum performance more predictable across congested WANs. Lost packets are reconstituted in real-time at the far end of a WAN link, avoiding delays that come with multiple round-trip retransmissions; out-of-order packets are resequenced, avoiding retransmission and processing delays that occur when packets arrive out-of-order.

Silver Peak protects Documentum data in-flight between locations with an Accelerated IPSec virtual private network (VPN) running AES-256, the enterprise standard for data encryption. Data-at-rest within Silver Peak instances is also encrypted with AES. End-to-end encryption is provided by SSL/TLS.
