SAP NetWeaver features the System Landscape Directory (SLD). For those of you not familiar with the SLD only so much: SLD gathers information on system landscape and software catalog (for details, see our SLD presentation).
The latest version of the SLD is running on SAP NetWeaver 7.1. The most important new feature of this version perhaps is the full automatic content sync, which allows setting up two or more SLDs – see the presentation for reasons to have more than one SLD and other details – in a way that all content of one SLD is copied automatically into another. Since this type of synchronization can be set up as well in both directions between SLDs, they can be kept identical content wise:

This figure shows two SLDs set up with bidirectional full automatic sync. All system data from SLD data suppliers plus any manually added data will be kept in sync automatically in both SLDs.

Besides that the UI was given some attention and minor bugs in content sync have been fixed in SAP NetWeaver 7.10 SP5 (this will also be part of the SLD as part of SAP enhancement packages for SAP NetWeaver 7.1). 
So you might ask yourself: “How do I get an SLD of SAP NetWeaver 7.10?” – Well, there are always two ways to install an SLD in the system landscape: Use a dedicated server for the SLD or install SLD together with another application. Also with SAP NetWeaver 7.1 there will be these options, namely:

  •  Installing the SLD together with another application will be possible with
    SAP NetWeaver 7.1 usage type PI (SAP on DB2 for Linux, UNIX, and Windows)
    Adaptive Computing Controller (Adaptive Computing) of SAP NetWeaver 7.1
    SAP NetWeaver 7.1 CE and Enterprise Services Repository & Registry (Enterprise Services Repository&Registry)
  • Installing the SLD on a dedicated server is planned to become available with SAP enhancement package 1 for SAP NetWeaver CE 7.1. Its availability will be announced in SDN.

For details how to assess the pros and cons of these options and our recommendations regarding SLD in your system landscape see SLD presentation and SLD Planning Guide.

    Quick question:
    if you install ACC with the SLD 7.1 can you use that SLD 7.1 also for a SOLMAN installation? PI 7.1 has the SLD 7.1 too, e.g. a full sync can happen but SOLMAN has normally SLD 7.0, e.g. can you attach SOLMAN to the ACC SLD or does SOLMAN need to have its own SLD on 7.0? Otherwise a full sync is not possible between the different versions.

      In the SLD Plannning Guide also available on SDN (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e0a1a8fb-0527-2a10-f781-8b67eab16582) such questions are discussed in detail. To put it in a nutshell: SAP Solution Manager should have a local SLD of its own, so it only can be of SAP NetWeaver 7.0 release, which is the one underlying the most recent Solution Manager release (with or without SAP enhancement package 1 for SAP NetWeaver). This is, however, nothing to hinder you in using it – even when you cannot update it with full automatic synchronization – since the important data for SAP Solution Manager is delivered by bridge forwarding, which works fine with 7.0.

    Please update your blog.  I see serveral documents that discuss the advantages of “Automatic SLD Synchronization” as of realease NW 7.1 but I not be able to find an article that tells me how I can create a standalone, NW 7.1 AS JAVA, SLD system.  Any help you can provide would be greatly appriciated.
