Table 19-5	Elements to Configure DMS-CD Deployment Thresholds
Element		Description
Number of		The maximum allowed number of FTP or SFTP threads, or sessions, that can run concurrently when
concurrent		DMS-CD provisions assets to DMPs.1 Therefore, the maximum number of DMS-CD deployments that
deployments		might possibly run concurrently in your WAN, if each such deployment targets only one DMP. Otherwise,
		when any deployments target multiple DMPs, this constraint limits how many DMPs can possibly receive
		deployments concurrently in your WAN.2
		Tip	When you use DMS-CD, it is a best practice that none of your DMP groups should contain more than this
			number of DMPs. If you ever reduce this value, check that doing so has not caused any of your DMP groups to contain
			more DMPs than the new number.
		The permitted value is any whole number in the range from 1 to 1000. The factory-default value is
		100 threads. We recommend that you avoid using any value greater than 100. Each incrementally higher
		value authorizes more concurrent DMS-CD deployments to DMPs and an increased load on your DMM
		appliance. You might try reducing this value if you notice that the CPU load is high on your DMM
		appliance during DMS-CD deployments.
		Note	Any time that you change this value, you must restart your DMM appliance before the changed setting takes
			effect on your DMPs.
Deployment time		The count of how many minutes will be allowed to elapse after a DMS-CD deployment package begins
limit per file (in		to provision any file. Upon reaching this threshold, the file moves to the back of the queue and its transfer
minutes)		is deferred.
		The next file advances to the front of the queue and the deployment continues. DMS-CD applies this
		threshold to a deployment package as many times as necessary until it has cycled through all of its files,
		and then the transfer is resumed for a deferred file after it returns to the front of the queue. This threshold
		might cause the transfer of any especially large file to be distributed across days. Bottlenecks are
		prevented and as many assets are provisioned as can be provisioned.
		When you derive this value from the maximum transfer rate, large files in DMS-CD deployment packages
		are more likely to transfer quickly.
		The permitted value is any whole number in the range from 1 to 10080, where 10,080 minutes is the same
		as 168 hours or 7 days.The factory-default value is 1440 minutes, which is exactly 24 hours.
Deployment retry		The count of how many times DMS-CD should try again to restart a failed deployment, until DMS-CD
count		stops trying.
		In combination with the deployment retry time, this setting has significant impact on how long it takes
		DMS-CD to detect failed deployments. For example, 5 retries x 300 seconds = 1,500 seconds
		(25 minutes), while 5 retries x 30 seconds = 150 seconds (2.5 minutes).
		The permitted value is any whole number in the range from 1 to 100. The default value is 5 retries. We
		recommend that you do not change this value.
