SAN migration status

Posted by martijnl on December 17, 2006

For those who are interested: we are now in our second day of the SAN migration from MSA1000’s to an EMC CX3-40.

So far everything is going OK, with a few hiccups yesterday evening. The speed of the migration (we use EMC’s SANCopy for the data move) has surprised us with seven out nine LUN’s ready by yesterday six o’clock in the evening. Two LUN’s from one MSA, with primarily fileserver data, didn’t copy over normally. We suspect because of the controller having difficulties with the I/O load. After the EMC consultant rescheduled the copy jobs and moved them to another storage processor on the CX they competed fine at nine o’clock yesterday.

All that is left now (…) is to patch the fibers to the new Cisco MDS9020 SAN switches, configure the zones for the servers / LUN’s and bring the servers online with their new storage.
