IBM® Lotus Notes® and Domino® are robust platforms for enterprise collaboration, including a wide variety of tools for messaging and directory services, discussion, calendaring, and document management services. While the IBM Lotus family was designed for deployment across distributed enterprises, there are inherent challenges associated with collaborating across a Wide Area Network, including poor application response time and excessive bandwidth usage. These are solved using Silver Peak NX Series appliances.
Silver Peak Advantages
Silver Peak has demonstrated 50-100x peak performance improvements when delivering Lotus Notes and Domino services to remote offices. This is achieved via the following techniques:
Data reduction
Silver Peak uses Network Memory™ technology to inspect all traffic that is sent between clients and servers, storing information as a local instance in Silver Peak appliances. Duplicate information is delivered locally rather than sent across the WAN, improving application performance and WAN utilization. In addition, advanced crossflow payload and header compression techniques further reduce the amount of email traffic traversing the WAN, resulting in maximum bandwidth utilization and LAN-like email performance.

Latency and Loss mitigation
Silver Peak uses various TCP acceleration techniques, such as window scaling and selective ACK, to improve email performance across the WAN. In addition, Silver Peak NX Series appliances use Network Integrity to mitigate the effects of packet loss across enterprise WANs and avoid unnecessary retransmissions.
Quality of Service (QoS)
Large volumes of email traffic can have a negative impact on other business critical applications. Silver Peak provides a robust set of Quality of Service (QoS) capabilities to prioritize real-time traffic, like Voice over IP (VoIP), avoiding delay and jitter and ensuring adequate bandwidth for all enterprise applications.
Notes/Domino Web Access
Silver Peak provides significant performance improvements when using Notes/Domino Web access, because Network memory is application-independent. As a result, data reduction works on HTTP traffic, which is the protocol used by Lotus Web access. In addition, Silver Peak’s payload and header compression, latency/loss mitigation, and QoS techniques all work equally well on web-enabled Notes/Domino environments.
Deployment Scenarios
Silver Peak addresses many facets of Notes/Domino deployment, including server-to-server and client-to-server interactions. This includes the following specific functions:
- Real-time access to Domino servers using Lotus Notes, Web Access, and other email clients.
- Replication between distributed Domino servers
- Replication between Domino servers and Notes clients
- Mail routing between Domino servers and email clients
