                 This technical note describes how to use the Steelhead appliance with Lotus
                 Notes and Domino Servers. It includes the following sections:

                 Introduction
                 Some basic Steelhead appliance interoperability tests have been performed
                 with Lotus Notes 6.5.1 and Domino Server 6.5.1. All functions that were
                 attempted ran successfully (for example, login, e-mail, calendaring), and
                 heavyweight functions (for example, saving attachments to local disk) were
                 accelerated (50-70x over 256k WAN, 10-20x over T1). Both in-path and out-of-
                 path configurations were tested.

                 To ensure that the Steelhead appliance can accelerate Lotus Notes traffic, the
                 data must be available in unencrypted and uncompressed form. Lotus Notes
                 and Domino servers have the ability to perform encryption and compression
                 at the port level and compression on a per-attachment basis. These features
                 must be addressed to ensure the Steelhead appliance can perform optimally.




                 Port-Level Encryption and Compression
                 In Lotus Notes and Domino 6.5.1, port-level encryption and compression are
                 disabled by default. You must confirm that port-level encryption and
                 compression are disabled to ensure maximum performance by the Steelhead
                 appliance.


Domino Servers   The following section describes how to confirm that port-level encryption and
                 compression are disabled for Domino servers.

                               !   From the Domino Administrator's Tools menu, choose Server->Setup
                                   Ports.
                               !   From the Web Administrator's Port tool, choose Setup.

                             4. Select the port you want to check.

                             5. Confirm that Encrypt network data and Compress network data are
                                unchecked.

                            Per-Attachment Compression in Lotus Notes
                            When you compose an e-mail message in Lotus Notes and you want to attach
                            a document, in the Create Attachment(s) dialog box, there is a Compress check
                            box that is always checked by default.

                            Ideally, there should be a way to have this check box unchecked by default, or
                            have it not appear at all (defaulting to do not compress). The likely place for
                            this configuration would be in a Desktop Policy Settings Document configured
                            on the Domino server. However, the do not compress option does not seem to
                            exist today. Riverbed is pursuing this issue with IBM Technical Support.
