Your architecture options for Hyper-V aren\u2019t just limited to a single hosted server or a single site cluster.\u00a0 They won\u2019t cover you for DR. <\/p>\n
There\u2019s lots of options out there.\u00a0 If you have huge budget and diskless hosts, you can replicate a SAN from site A to site B across dark fibre.\u00a0 Initiating the DR site is easy.\u00a0 Ensure site A is offline and power up site B.\u00a0 Because the hosts are diskless, they store everything about themselves (operating system, identity, configuration, services and data) on the replicate SAN.\u00a0 As long as the site B hardware is identical you can power it up and carry on working as before. <\/p>\n
That sounds perfect, eh?\u00a0 But dark fibre is expensive!\u00a0 You might be able to get away with 1GB copper but that\u2019s really pushing it for SAN replication. <\/p>\n
More affordable is host based replication.\u00a0 I just saw that Double-Take has a few solutions<\/a>.\u00a0 Note that HP customers can get HP rebranded Double-Take software.\u00a0 You can replicate VM\u2019s on a single host to another host using Double-Take for Windows.\u00a0 Or you can use GeoCluster to get much more advanced solutions. <\/p>\n This also reminds me that you can use things like Double-Take or Replistor to do P2V DR of data (not operating systems and applications), e.g. you can have a production physical SQL box called SQL1 and replicate the SQL databases and log files to SQL2 which is an identically configured VM in the DR site. <\/p>\n An interesting way to do is to continually P2V your machine using an imaging solution that can handle drivers.\u00a0 Acronis have a great reputation for driver substitution in their imaging solutions.\u00a0 Their True Image Echo Enterprise Server<\/a> solution allows continual P2V of physical machines to virtualised DR machines.\u00a0 Invocation is a restoration of your stored images, something you can regularly test in Hyper-V with private networks.\u00a0 That Acronis product supports lots of operating systems.\u00a0 There\u2019s a cheaper version for Windows<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" Your architecture options for Hyper-V aren\u2019t just limited to a single hosted server or a single site cluster.\u00a0 They won\u2019t cover you for DR.
