HDS server down

Just want to discuss the impact on the implications when one HDS server goes down (out of 2) is taken down for maintenance.  From what I understand there should be no impact.  How long does it take to replicate the data back, if one HDS server is down for 12 hrs or so ?

Hemal,

As the HDS does not perform any routing, there is definitely no customer-facing impact to taking it down for maintenance. Replication speed will depend on a number of factors - server size, call volume, network connectivity between sides, etc. 

I would expect that the replication would take far less than the 12 hours the server was down for, likely somewhere between 30 minutes and 4 hours. Just a guess though, as there are so many factors that would go into it.

Be sure the HDS you are taking down is not being used by anyone for reporting.
