Hello,
We are transitioning datacenters and looking for optimal data migration techniques. Our current filers are Ontap 8.2 7-mode and we will be moving to new filers at Ontap 8.2 Cluster mode. With this configuration snapmirror is not an option as it does not work from 7-mode to cluster mode filers. We have about 40 TB of data to move, in which half is for a vSphere environment and the other half are direct attached storage to physical servers. The physical servers are a mix of UNIX and Windows and the protocol is mostly iSCSI, but we do have a few NFS volumes as well. We plan to migrate the vSphere storage using Storage vMotion technologies. Our current struggle is to find the best way to migrate our iSCSI data on the physical servers. We ran across the NetApp DTA2800 device as a possible solution, but there seem to be a lot of set backs. It seems that the DTA2800 only supports offline migrations for iSCSI luns. Does anyone know typical migration speeds of the DTA2800 for iSCSI migrations? Also, our new filers and old filers are in separate physical locations. Does the DTA2800 device support migrations between datacenters? What other options might we have to migrate our iSCSI data, online and at an optimal transfer speed?
Thanks for any input you can provide!
