absolutely -- after a few weeks of migration effort (my own choice to move clients in phases to mitigate risk), i have moved several thousand clients from bare metal + tinydns to ucs/vmware/bind with no reported issues.
many of these are demanding "power users" (developers with what i'd often categorize as "insane" workloads, firing off queries in batches of 10's of thousands of uncached forward/reverse RRs). that said, we were fairly cautious and chose to deploy load balanced vips as our nameservers in resolv.conf. this imposes a slight hit as each cache must be warmed independently (some sort of mechanism allowing a single cache to be shared amongst a cluster of binds via rpc or similar would be cool, while imposing it's own overhead), but gave desired resilience in the case of individual virtual machines getting overloaded or ucs chassis/switches/etc requiring maintenance. each vip has a set of virtual machines on separate power sources, network uplink, etc. we also use cfengine to creatively alternate odd/even-numbered hosts across vips (you could do this with any DNS software, and i recommend it along with the use of 'options' -- if you don't have legacy clients which won't support it -- so failure of a single VIP/server won't maim entire clusters), and got better monitoring thanks to statistics-channels. -----Original Message----- From: "Manson, John" <john.man...@mail.house.gov> Date: Tuesday, June 5, 2012 9:58 AM To: "'bind-users@lists.isc.org'" <bind-users@lists.isc.org> Subject: VMware & Bind >Will bind run on VMware? > > >John Manson >CAO/HIR/NI Data-Communications | U.S. House of Representatives | >Washington, DC 20515 >Desk: 202-226-4244 | Team: 202-225-5552 | john.man...@mail.house.gov > > > > > > >_______________________________________________ >Please visit https://lists.isc.org/mailman/listinfo/bind-users to >unsubscribe from this list > >bind-users mailing list >bind-users@lists.isc.org >https://lists.isc.org/mailman/listinfo/bind-users _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
