I've to do a migration of two servers with large SAN attachments to our new VMWare environment.
EDIT: I have to supply some additional intelligence as I have good answers regarding VMWare solution.
Ok so, I can't attach a previous EMC LUN on the New system due to some technologies limitations on the server.
I can't use VMWare Converter to clone the missing volumes on my new VM as VMWare Converter can't see EMC PowerPath Pseudo-devices and that the previous admin used those Pseudo-device to built LVM2 and/or ASM volumes on top of.
Those two physicals servers are attached to an old EMC² CX-340 SAN and handle 5TB of data.
Those 5TB of data are small PDF and I need to transfer them to the new machine through our 1Gbit/s LAN.
I've tried using
rsync, but it's really to slow and have a strong impact on the RAM and CPU performance.
I've try using NC with TAR but the transfer rate is quite slow as I've an average throughput of about 50MB/s on a 1Gbit/s link with barely zero traffic.
Could you give me some advice or return of experience with this kind of migration and how you manage to have it finished correctly within reasonable amount of time?
