The virtualization of data storage space can lead to significant cost savings when a company is faced with the need to make a physical move, whether that move is merely across town or to another state entirely. When storage is virtualized, it becomes possible to carry out a data migration to a new center during working hours rather than on the weekend when overtime costs will make the move more expensive.
With virtualized storage, data migration becomes a simple matter of telling the computer system to move a LUN to a new target array located in the destination. Compare this to older forms of data migration, which might involve voluminous file transfers over the internet or even a physical migration of hard drives from one location to another. Either one of those methods has other drawbacks besides cost. Data can become corrupted during transfers, or worse, it can be intercepted, which can cause any number of serious issues for the company.
Data transferred by means of physical hard drives can become damaged during a move, particularly if the drives are subjected to too much vibration. While not catastrophic, this usually means a need to restore from backups, which can be time-consuming and disruptive to normal workflow. In addition, either traditional option for data migration can mean downtime during which it becomes inaccessible for employee use.
Virtualized storage, in contrast, creates a way to migrate data with no downtime. A managed services provider can assist businesses to get up and running with virtualization.
