remote Xserve RAID replication

[Noam Birnbaum]

Hi folks,

A prospective customer has two Xserve RAIDs, in offices about 30 =20
miles apart.  The RAIDs hold production files, the largest of which =20
are CS3 documents, some of which are in the low gigabytes in size.  =20
They would like a system that comes as close to mirroring the content =20=

as possible.  I told them that actual real-time mirroring was a =20
Fortune 500 company's pipe dream, so instead they want to look at =20
recurring replication on the bit level.

Users at each location will be working on both RAIDs but they assure =20
me that their traffic department is taking steps to ensure that =20
there's no file locking problems.  This remains to be seen, but I'll =20
take them at their word for now.

So let's start simple: assuming these two RAIDs were in the same =20
physical room, how would you mirror them over Ethernet?

Then, since they're NOT in the same room, what are decent solutions =20
given the fact that this needs to take place over broadband?

Let's say they went for nightly replication.  We've worked on one-way =20=

rsyncing but never two-way.  How could that work?

Thanks all!
