HP Autonomy

Don’t let the wide area network interfere with your HP Autonomy deployment. Silver Peak fixes the WAN problems that can undermine HP Autonomy over distance. Autonomy users can retrieve files faster from the cloud and/or data center. IT can more easily integrate remote data repositories into the Autonomy IDOL architecture. With Silver Peak, IT can deliver a more responsive and more predictable HP Autonomy experience to every remote location.

HP Autonomy (formerly Interwoven) is a powerful enterprise content management system allowing organizations to better access and manage business documents and information. As HP Autonomy deployments expand to remote locations or move into the cloud, performance problems may emerge for some users. Content may take longer to retrieve while IT from remote repositories may find it more difficult to integrate repositories into Autonomy’s Intelligent Data Operating Layer (IDOL).

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 Autonomy decrease 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 Autonomy to fix the problem as the causes of delay often lie in the Internet not the cloud provider’s network.

Silver Peak compensates for network limitations, allowing IT to deliver a faster, more consistent HP Autonomy experience to any location regardless of whether the repository resides in the cloud or a remote data center. More specifically, Silver Peak solves the following networking problems undermining Autonomy performance:

• Bandwidth – Silver Peak byte-level deduplication removes redundant data from the WAN. The first time Autonomy sends data it is fingerprinted and compressed by Silver Peak. Subsequent requests are fulfilled by the local Silver Peak instance. Customers experience shows that Silver Peak can reduce the amount of bandwidth required by HP Autonomy by 6x.
• Latency – Silver Peak mitigates latency, enabling Autonomy to operate more efficiently over distance using TCP Acceleration, which includes windows scaling, selective acknowledgements, and HighSpeed TCP. Accessing CIFS-mounts is made faster with CIFS Acceleration, which includes CIFS read-ahead, CIFS write-behind, and CIFS metadata optimizations. 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 Autonomy 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 Autonomy 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 in Silver Peak instances is also encrypted with AES. End-to-end encryption is provided by SSL/TLS.
