[Lustre-discuss] remote volume mirroring

[Brian O'Connor]

Hi

I'm not hopefull, but I notice that some raid devices support
remote volume mirroring. 

ie.

http://www.lsi.com/DistributionSystem/AssetDocument/documentation/storag
e/software/ESG_RVM_PB_030608.pdf

if the MDS/MGS and OSS's are on a raid devices that support
RVM, could I use this to sync a production and remote DR lustre
cluster?

I seem to remember that even if this works I'll only be able to mount
the lustre volumes on the remote site if I use the same IP numbers in
everything. Are there any other hardware dependancies that would
stop an active block level lustre mirror.?
