I would like to implement BES 5.0.2 for both local HA and DR...any suggestions on how I would do that.

2 x BES Ent Server
2 x BES Attachment service
2 x BES Admin service

SQL 2008 server clustered for config DB

The BES servers will be installed on VMware, so this could be leveraged as well.

Many thanks.

Hi,

I would consider using BlackBerry 5.0.2's inbuilt HA capability for the primary site with Primary and Backup BES servers, a Attach Server Pool and the BlackBerry Administration Pool.

SQL Clustering is not currently supported - you'd need to mirror your SQL database on 2 separate SQL servers, ideally with a Witness to handle automated failover.

With regards to DR, you could consider using DoubleTake or Neverfai -  both of these will effectively create identical duplicates of your servers with byte level changes being replicated and they will have the same names, IP addresses etc. Upon DR invocation, they automatically assume the identity of the old servers and everything carries on as if nothing happened. Whilst the 'standby' servers are being updated, they do not connect to the RIM network so no SRP blovking can occur.

RIM's suggestion for DR is to have the HA components split across datacentres - not ideal.

What version Vmware do you propose to use - this might provide the answer for DR?

Regards,


RobMobility.
