MD SRA device management service
The MD SRAsvc process monitors and synchronizes communications between the SRA and the MD storage arrays. SRA workload is
partitioned between a persistent server and multiple transient client programs, which endure only during a single SRM command.
Because it is typical to run many SRM commands while performing a single SRM workow (such as test failover), clients come and
go frequently, while the server, running as a Windows Service, persists and manages all communications with storage arrays.
Typically, you do not need to congure the server, which functions at its default values. When it is necessary to congure the server
for nonstandard operation, there are two les that you can edit (for dierent reasons):
The SRA Conguration le, SraCongurationData.xml – in the cong directory under the SRA’s script directory, typically C:
\Program Files\VMware\VMware vCenter Site Recovery Manager\storage\sra\MD\config
\SraConfigurationData.xml.
The Win32 Service initialization le, NesSvc.ini, in the win32svc directory under the SRAs installation directory, typically C:
\Program Files\VMware\VMware vCenter Site Recovery Manager\storage\sra\MD\win32svc
\NesSvc.ini.
Server settings in SRA conguration data
The portion of SraConfigurationData.xml relevant to service conguration is the following:
<SraService>
<SvcHost>localhost</SvcHost>
<ServicePort>1701</ServicePort>
<ListenBacklog>100</ListenBacklog>
</SraService>
Its content is as follows:
SvcHost : determines the host on which NesSvc is running. The only allowed value is “localhost”. In future releases, it may be
possible to share instances of NesSvc across multiple installations of this SRA, further enhancing performance and simplifying
cooperation between multiple SRA instances.
ServicePort: determines which IP port the service uses for socket communications between the client and server. If another
application on your system is already using port 1701 (the default), then, set this value to another port number.
ListenBacklog: congures a performance property of the port. You should modify performance property only when consulting
technical support personnel.
SRA Windows service initialization le
In normal circumstances, you should not modify the windows service initialization le. The exception is when you need to modify the
virtual settings that the server uses. After consultation with technical support, you can modify the following lines:
