What is storage virtualization?
The management of most businesses’ data storage is a time-consuming and expensive task. When data storage is spread over multiple protocols,operating environments, application servers, and remote locations, the chance for human error increases.
Storage virtualization arose as a solution to ease management requirements. The first step toward storage virtualization is combining your physical storage volumes across multiple platforms and vendors, and dividing them out into “Virtual Volumes”.
These Virtual Volumes can be spread across any amount of your physical storage volumes, without regard to topology or the physical layout of the storage. This storage abstraction makes the physical pathing, devices characteristics, and physical data location of your volumes invisible to your hosts.
Why storage virtualization?
Storage Virtualization simplifies the management quirements for your company’s data storage infrastructure and applications. You can allocate volumes and repurpose data storage resources as your IT infrastructure changes. With storage virtualization capabilities, you can reallocate Virtual Volumes again and again with ease, and utilize unique storage applications that require Virtual Volumes, like Mirroring, Snapshot & Remote Replication.
In addition to simplifying management costs for your data storage, virtualization allows you to maximize the utilization & capacity of your data storage devices. You can buy a single physical storage device to add into your virtualized SAN, and increase the size of multiple volumes, rather than having to buy multiple devices to increase the capacity of your DAS (direct-attached-storage) volumes.
Also, you can greatly maximize the throughput and performance of your storage devices by allocating frequently accessed data on high-performance disk, and infrequently accessed data on legacy storage devices and tape. You can increase performance of you storage infrastructure even more with load balancing & multi-pathing.
How Do I Get Started?
For true storage virtualization over multiple devices (tape, SSD, SATA disk), protocols (SCSI and Fibre), operating systems and platforms, you have to purchase a dedicated storage server.
