Choosing the right technology for DR site SAN replication technology

[albertwt]

Hi Everyone,

I am confused of which one is the most preferable choice for DR environment ?
###between SAN based replication technology or 3rd party application (Veeam Backup and replication or VMware Site Recovery mgr.)

my current situation is that I have running mostly virtual environment

production environment that is mixed of HP DL 380 and Blade servers with EMC Clariion CX4-500 FC-SAN
planning for DR environment that uses the same server model but still thinking of which SAN technology that we could use for the replication between the two sites ?

the DR site is not necessarily to be as fast as the current production and the SAN doesn't have to be EMC

Any comments would be greatly appreciated.

Thanks.

You can do replication at host level have you considered double-take?

hm.. haven't think about that yet, let me have a look around then.
