5 sites and 1 datacentre - will 1 DC in each site be enough

-

hi everyone,

just want ask how other people doing , see if complete no go!! title says have 5 office sites , 1 data centre. have 2 dc's in datacentre , 2 dc's in each office site. each office site connected in hub , spoke network datacentre minimum 50mbps lines.

i looking @ upgrading our domain controllers windows server 2012 r2 , in same instance playing thought of removing 1 dc each office site. still keep 2 in datacentre.

on client side use dhcp point local dns first , different office secondary dns server.

i going view if local dc down office available , 50 , 100 mbps mpls connectivity between sites should enough not noticing long logon delays.

any advice ?

regards

hiya,

it depends on size of site(number of users). if not looking @ thousands of users per site, should fine 1 dc @ site. multiple dc's primarily; 1: fault tolerance, 2: load of users.

as domain has multiple dc's fault tolerance fine. if number users not surpass capabilities of single dc, fine there too.

you need suffer both local dc outage , isp outage users unable use domain services. depending on user load, given line speed should more sufficient.

in terms of dhcp, local dc first, datacenter dc second recommendation, in spoke-hub network.
