Because we currently have 250k clients in SCCM 2007 and will probably have 350k or so when you take into account mobile devices, UNIX and Mac devices if we go with all them in SCCM 2012.
We need a CAS because of our size. Thank you.

I also spoke to MS, who also confirmed. I don’t like that fact that a CAS needs to be online for new records to be created, but it is what it is. http://technet.microsoft.com/en-us/library/gg712308.aspx About Discovery Data Records<javascript:void(0)> ________________________________ Discovery data records (DDRs) are files created by a discovery method that contain information about a resource you can manage in Configuration Manager. DDRs contain information about computers, users and in some cases, network infrastructure. They are processed at primary sites or at central administration sites. After the resource information in the DDR is entered into the database, the DDR is deleted and the information replicates as global data to all sites in the hierarchy. The site at which a DDR is processed depends on the information it contains: · DDRs for newly discovered resources that are not in the database are processed at the top-level site of the hierarchy. The top-level site creates a new resource record in the database and assigns it a unique identifier. DDRs transfer by file-based replication until they reach the top-level site. · DDRs for previously discovered objects are processed at primary sites. Child primary sites do not transfer DDRs to the central administration site when the DDR contains information about a resource that is already in the database. · Secondary site do not process discovery data records and always transfer them by file-based replication to their parent primary site. DDR files are identified by the .ddr extension, and have a typical size of about 1 KB. Thank you.

In looking over the ddm.log on W01 (Tier 2 Primary) after AD Group discovery finds a machine that was just added to the group; I see the info below: >> The site will not process newly found System from Agent >> SMS_AD_SECURITY_GROUP_DISCOVERY_AGENT [cid:image001.jpg@01CE92B4.DA224290] We have a CAS, and the discovery is occurring at the Tier 2 primary called WDR. If a new record comes in from a primary (ex: AD Group Discovery, AD User discovery, client registration for new client) does that new record 1st need to be forwarded up to the CAS to create the record (I’m assuming this is how the resource ID for the object is the same on all SCCM servers) and then sent back down for the primary to process? This would mean that if the CAS is down any new records that are created (new client installed, new groups created, new users added) won’t be processed for my entire environment until the CAS is back online? That seems like a pretty big single point of failure, as if the CAS is down I won’t be able to do anything with new objects. Our thinking was if the CAS went down worse came to worse we could always scope down to each primary and create advert/deployment if need be. It sounds that wouldn’t work for new objects. We have over 300k clients, so we need a CAS. Thank you.
