You have a VMware infrastructure in place. That’s a great start! But what about your storage? VMware allows IT to be more agile at the server level, but most of the time storage is still the roadblock to a fully agile and safe infrastructure.
Storage virtualization allows servers to be independent from the physical storage. It shields the server from the underlying hardware, and basically presents virtual LUNs to the servers. One may be worried about performance. But the good news is that it actually increases the performance. Instead of having a few LUNs in the red, and most others sleeping, storage virtualization spreads the load across the physical disks.
Storage virtualization is useful if your goals are to:
- Provide agility by removing the necessity to be tied to physical LUNS in the SAN.
- Implement a fully redundant storage infrastructure, locally, or to a remote site
- Keep the storage up 24x7
- Migrate data from an old to a new SAN (same brand or not)
- Keep older SANs in production, knowing you can migrate the data easily anytime
- Increase the performance of storage.
