DMD Data Systems offers storage migration services

Upgrading your storage infrastructure? Enlist DMD’s Technical Services team to migrate your data for a seamless transition. Certified in IBM, NetApp, and  EMC storage infrastructures, our architects and engineers are experts at disk-to-disk migrations from legacy systems. There are a plethora of techniques we use to migrate virtual servers between hardware platforms and also to migrate “physical” servers to “virtual server.” We can also perform Microsoft Clustering services, which consist of a couple different types of migration.

Network migration—This is the slowest type of migration and performs a network copy of the virtual machine data using BITS. The amount of downtime is in direct proportion to the size of the data transfer. When you migrate a virtual machine into a cluster by using a SAN transfer, VMM checks that each node in the cluster can see the LUN, and automatically creates a cluster disk resource for the LUN. To migrate a virtual machine out of a cluster, the virtual machine must be on a dedicated LUN that is not using CSV.

Live migration—This type of migration moves a virtual machine running as part of a failover cluster from one cluster to another with no noticeable downtime for users or network applications.

SAN migration—This type of migration uses SAN transfer to migrate virtual machines, and highly available virtual machines, into and out of a cluster. It can be used when both the source and destination hosts have access to the same storage infrastructure (LUN), and the storage can be transferred from one host to another. For SAN migration, the files for a virtual machine are not copied from one server to another and thus downtime is minimized. SAN migration can be used to copy a virtual machine from one host to another, or copying a virtual machine to or from the library.
