Choose SCCM DP Vs Secondary site Vs BDP

1) Implementing the Secondary site

Pros:-

    Ø  Traffic  can be compressed/ Scheduled/Throttled & rate limit on the  address

Ø  Secondary sites do not require additional Configuration Manager 2007 server licenses.

Ø  Secondary sites do not require an additional SQL Server database at the secondary site.

Ø  Clients can be managed across a slow network connection link, such as a wide area network (WAN) connection between sites, without the need to configure client agent settings.

Ø  Secondary sites can have management points (called proxy management points) to help prevent client reporting information, such as inventory reports and status messages, from traversing slow network connections to the primary site.

Ø  Remote sites can be managed centrally from a parent primary site without the need for an on-site administrator at the secondary site. Less administration when compared with primary sites, After enabling client push binaries can be pushed from here.

 

Cons:-

Ø  Required a server OS

2) Implementing the Distribution points:-

Pros: -

Ø  Distribution points can be configured as Protected DP

Ø  Can configure DP Groups for easy selection of DP’s

Cons: -

Ø  DP’s always a SMB copy (that cannot be scheduled, compressed or throttled).

Ø  Required a Server OS and Drive space

Ø  Up to 100 per site, each capable of supporting up to 4,000 clients

3) Implementing the BDP’s:-

 

Pros:-

Ø  Can be configured on any SCCM Client OS (Server and Workstation systems)

Ø  Communication will happened over the BITS and can be resumed

Ø  Computer Client Agent Properties can be configured with BITS Throttle period

Ø  Content can be set to on demand for clients

Ø  Can have multiple BDP’s

Ø  Will fit for Branch offices where 2 -100 systems

Ø  Will download the package from Standard DP

Cons:-

Ø  Branch Distribution Points cannot be placed on server shares

Limitations:

 

Ø  Up to 2,000 per site, each capable of supporting up to 100 clients

My recommendations are:-

 

Number of Systems	Recommended Role
50 – above 150	If you don’t care about up & downwards bandwidth then choose DP
2 - 100	BDP - Protected
100 above	Secondary site

if there is a below 100 systems then just go for BDP role on Server based OS

What and Where you can control the Network Bandwidth

Ok.. Now you want to know here are all the bandwidth can be controlled in SCCM

 

Package Movement	Bandwidth Control	Uses Binary Differential Replication?
From package source directory to site server	None.	No
From site server to standard distribution point	None.	Yes
From parent site server to child site server	Bandwidth controlled by Address settings on the sender between sites.	Yes
From child site server to child standard distribution point	None.	Yes
From standard distribution point to branch distribution point	BITS or manually pre-staged on the branch distribution point. For more information	Yes
From standard distribution point to client	BITS, if BITS-enabled distribution point is available and advertisement is configured to download and run locally.	No
From branch distribution point to client	None.	No

SCCM Senders End to End

Senders can be configured on only Primary and Secondary sites, the use of senders are instead, senders use existing network connectivity to manage the connection, ensure the integrity of transferred data, recover from errors, and close the connection when it is no longer needed.

Types of Senders : 6 types

1) Standard Sender

The standard sender is installed and configured by default on all primary and secondary sites. If your site-to-site communications occur over a LAN that uses a supported protocol, you do not need to install another sender.

if you want to apply some bandwidth restrictions between site to site communication. here are the options for Standard Sender.

 

 

2) Courier Sender

The courier sender is installed and configured by default on all primary and secondary sites. It is not displayed, and cannot be created, in the Configuration Manager console because it must be manually started from the Configuration Manager programs folder on the Start menu. Courier senders are used only for software distribution to send package data to other sites by using physical media instead of sending data over the network. To use the courier sender, you must first create a standard sender connection between the parent site and the child site. Once the standard sender is created, you then create a courier sender address for each site to use the courier sender functionality.

When you have large packages that require excessive time or bandwidth to be sent over the network, this sender can be useful. You can use courier sender at the source Configuration Manager 2007 site to create a parcel (that is, a collection of files transferred from one site to another using courier sender); write the parcel to a tape, CD, or other physical medium; and then ship the tape or CD to the destination site by mail or a courier service. At the destination site, you can then use courier sender at that site to receive the parcel and import the package data into the site.

Note :- The courier sender is installed and configured by default on all primary and secondary sites. It is not displayed in the results pane because it must be manually started from the Configuration Manager 2007 program files on the start menu.

3) Asynchronous RAS Sender

Used for communication over an asynchronous line.

4) ISDN RAS Sender

Used for communication over an ISDN line.

5) X25 RAS Sender

For RAS communication over an X.25 line.

6) SNA RAS Sender

For RAS communication over an SNA link.

Ok.. Now if you in confuse what to use in your network after reading the above, Just check the below table you will get some more clarity where what type of sender you can use

Existing network connectivity between sites	Sender
LAN or WAN	Use Standard Sender, the most commonly used sender, for sending to other sites on the same LAN, or on a WAN using routers, switches, or bridges.
Asynchronous line	Use Asynchronous RAS Sender for RAS communications over an asynchronous line.
ISDN line	Use ISDN RAS Sender for RAS communications over an ISDN line.
X.25 line	Use X25 RAS Sender for RAS communications over an X.25 line.
SNA	Use Systems Network Architecture (SNA) RAS Sender in RAS communications over an SNA link.
No Connectivity to your office or None	Use Courier Sender to send packages between the sites by using removable media instead of network wiring and protocols if you have a slow or unreliable link between a site and its parent. Courier Sender is used only for package distribution, not site-to-site communications.

For my all Primary Site i have open the communication to be open all the time however for secondary sites i have done below recommendation based on the bandwidth and  clients size : this is again for Standard Sender

Pulse mode configure options

In real World :- You will use only Standard Sender
