Virtual LUN Technology
The Symmetrix V-Max storage array enhances the Virtual LUN technology offered by DMX storage arrays. The Virtual LUN technology on the V-Max array can now perform transparent, nondisruptive data mobility between storage tiers for standard Symmetrix devices. This technology is based on the Enginuity Virtual RAID Architecture and requires Enginuity code level 5874. Virtual LUN migration provides users the ability to move data between high-performance drives and high capacity drives. This new functionality is used to either change RAID protection types, move between physical disk groups, or both. It supports the migration of regular devices or meta-volumes, and can utilize configured or unconfigured disk space as the target. When the migration is performed to configured space, the target of the invocation cannot be assigned to a host. Migration is facilitated by the creation and movement of Symmetrix devices. Upon completion of the migration, the original devices are deleted and the space is freed.
CEO Joe Tucci touts V-Max as haVing been “purpose built for Virtual datacenters”, but how does it differ from Symmetrix DMX with respect to Virtualization?
The word “Virtual” means to make something appear to be real when it is not such has a reflection in a mirror. In the data storage world, Virtualization makes the location and size of LUNs/blocks/files appear to the serVer to be constant when they are not.
Let’s start with the DMX’s Virtualization features:
